Title: Retromini RS-90 (JZ4725B) gba micro handheld
Post by: Verdugo on November 19, 2017, 01:37:02 pm
Indstr mentioned this handheld in a previous topic: The retro mini https://www.amazon.com/Handheld-Console-Retro-Bran-new-Classical-Children/dp/B0777J6KVV/ref=sr_1_165?ie=UTF8&qid=1510859830&sr=8-165&keywords=handheld+game+tf+card .
After some searching I found out that the same handheld is also being sold on aliexpress under the name Revo mini : https://nl.aliexpress.com/item/REVO-MINI-Handheld-Game-Console-2-0-Video-Game-MP3-MP4-Speler-met-Backlit-40-Ingebouwde/32842291381.html?spm=a2g0s.8937460.0.0.e23i5g .
The photo's match the prototype renders on gbatemp: https://gbatemp.net/threads/theres-a-new-handheld-coming-the-revo-k101-mini.427939/ .
I'm not sure if I should order one through Aliexpress. The amazon reviews are all made by people who just recently opened an account. Thoughts?
EDIT: Actually it's not made by the Revo k101 people.

It's not hardware emulation but software. Still might get one next month, because of the nintendo style dpad  8)

I would seriously love to see a full review of this thing.  Does anyone know of one?  It's hard to Google for with so many differently named companies selling it.  Price is all over the place too, seems $50 is the low end on aliexp, with it topping out at $80-90 BIN noe eBay.

Hi all,

Have read through your posts and make a general video to show the Retromini operating. The video is raw in the sense that no cutting or speeding up has happened during the loading or game play in order to provide a genuine feel of the console. Excuse our in-game fails :P.

Without any patching it can read GBA, NES (SFC) and SNES (SFC). For GB and GBC it needs to be patched to GBA format and not all games will run perfectly. In order to run ROMS you must use a Micro SD card.

If you do not buy it from our website we cannot guarantee the functionality will be the same. Without bias it is a pretty cool system, in general I personally prefer a larger screen though (it is just 2").

Feel free to ask any questions.

Just ordered from Fasttech.  We'll see what happens.  I've been looking for a Micro-class system to carry around but manufacturers have been avoiding that size class for whatever reason.  I'll update you guys if it ever comes in.

We deal direct with the factory. For a competitor to sell at that price with shipping (as it has a battery included shipping is not cheap) they are definitely making a loss. -So seems like they are doing it as a way to build up their e-mail list + obviously they are obviously hoping to sell a large quantity so they can minimize the costs. Anyway, buying elsewhere means you will not get product support.

Within the actual console you mean? No. Only options within the console is for the saving slot feature. If you want to make changes to the ROM/s that would be something you would need to do yourself with software prior to loading it onto the console.

you might deal with the factory direct, but you're not based in China, probably don't speak Mandarin, and you don't have the buying power that Fasttech does. they won't be making a loss on these, FT is a giant - they don't need the custom that a few dozen emulators will net them.

FT support is excellent btw. they refund return shipping costs on failed units, and occasionally don't even require you to return the product at all in order to get a full refund.

$75 is just greedy, either that or the factory is ripping you off.

Post by: jonothan on December 08, 2017, 01:53:10 am
I was gonna say something about that too.  There are multiple sellers on eBay and Amazon who have it for $50 which is still $25 less than your price.  I appreciate the info you've contributed to this topic, but the Fasttech price makes the support argument a non-issue...especially when you could outright buy 2 units from them at the same price as 1 unit at your price.  It probably would've been better to just not bring it up or draw attention to it.

Retzone, I take it the "special software which only we provide" that patches gb/gbc roms to gba is just goomba or something, software which anyone can download and use? Nothing special and provided for free by it's authors. I also used a converter for sms roms back in the days of GBA flashcarts, can't remember what that one was called though.

Well, Fasttech emailed me last night saying my order shipped.

Did anyone else order one of these?  I'm actually looking at some of the adapters I have wondering if I'll be able to hack a bluetooth audio transmitter into it.  That would be pretty sweet.

My one from Datafrog on Aliexpress arrived today. Looks pretty good so far.  Came with a 8gb micro SD card too with a load of games on.

Not had chance to give it a proper go over yet as at work but looks decent for the money.

mine was shipped from FT this morning too. i was beginning to worry they'd listed them at the wrong price and wouldn't honour the purchases, but it seems not. :)

seems like a lot of redditors in /r/gameboy jumped on it as well.

i'm really looking forward to getting it, it'll be just in time for a plane journey too.

Hi guys, i read about miniretro, a kong feng color chasis with z4725B the same socs as PDC consoles, mi2, etc.. but that is true???. Miniretro emu fc, sfc, bin, and gba as pmp v has a best resolution.
the firts, socs inside is a pico32 intead of  MIPS z4725B either pico32 MZEF, MZDA or an arm m4 probably a family SAM SAMV7x or a $ plus. Ingenix z4725B is inside rs97 retro o a pap kIII, and the emulation  including cp1, NeoGeo, etc...

Not sure if I overlooked someone answering this already, but is there any chance of this getting a custom firmware? With the GBA resolution screen it won't make a huge difference in available game systems, but possibly in emulation quality.
Title: Re: New Retro mini: gba micro handheld
Post by: gibberish on December 12, 2017, 07:48:33 pm
i don't see why it should be impossible, since we have many other handhelds with the same/similar ingenic chip on them with custom firmware. but it takes someone with enough interest to make it happen. not sure if we're a bit late in the day for that, given the likes of GPDs machines etc.
Title: Re: New Retro mini: gba micro handheld
Post by: jonothan on December 13, 2017, 05:27:20 pm
The main reason I see potential in this device is purely the form factor/price combination.  In recent years, no one has really seen fit to produce any halfway decent devices approaching the Game Boy Micro size class, and if you've tried to price one of those original units then you know the cost for that system is only going up.  It's to the point now that I don't want to take my Micro (which I bought when it was new, so it's still mint) out of the house just because I know that if something did happen to it, I'd never be able to replace it.

As long as this thing's performance doesn't outright suck, there's no reason why it shouldn't become the go-to device for GBA in a truly pocketable format.  My own mental checklist has the following pros:

- The size, obviously
- Common, cheap, replaceable battery
- Possibility of buying a higher capacity battery
- Actual GBMicro quality screen

Potential cons:
- Don't know if controls suck
- Iffy performance?
- Shitty OS build?

In theory, if the build quality is good enough, it could very well be worth the time investment to tweak/optimize the software.

0. I am Chinese and I knew some review videos will show up online sooner or later and this is one of them, I knew it because this console showed up in the Chinese market a while ago and (Chinese) people had been talking about it in the gaming community since it came out.

1. I was about to preorder one but I ended up changing my mind, because ALL (not most, but ALL) of the gamers who received this console said that it had some serious slow-down and frame-drop issues. For those Pokemon or some RPG/strategy games, it is acceptable, but for those action games, it is literally unplayable. If you ordered this console and have it in hand, try some of the action games, e.g. Contra, Castlevania, Megaman, etc. you will understand what I am talking about in 2-3 minutes. Unless they fixed it or somehow updated the firmware, which I doubt, it will have these issues.

2. The screen on this console IS from the Gameboy Advance Micro, yes, you heard it right, it is literally the old stock screens from some old ware house somewhere in China. If you have the GBM, you can compare them yourself. But this screen here has some strange settings that the color on this screen is a little bit too 'blue' (or say it's a little bit too 'cold'), it might have something to do with the driver. The good thing about the screen, however, is that it has a 1:1 pixel perfect aspect ratio without any stretch.

3. The build quality is pretty good though, the d-pad and face buttons are OK but the shoulder buttons (L and R) are not very comfortable, at least for some people.

4. Overall, I would suggest to do more research before you order. For a time, I was thinking we are finally having a Chinese console that does not suck, but apparently not.

PS: Great video!
Title: Re: New Retro mini: gba micro handheld
Post by: gibberish on December 14, 2017, 09:06:00 pm
pretty much what i expected. 2011 levels of GBA emulation are assumed in a CPU from 2011, probably running 1:1 compilations of software from that era. sucks, but what ya gona do.

about the screen, very happy to hear it's 240x160. i would happily take a "cold/blue" LCD of the correct resolution over a vibrant display of the wrong res. you can't have it all.

will see about the placement of the shoulder buttons when it arrives. i can imagine them being awkward for fat handeds like myself.

It doesn't work it works painfully slow I tried Sonic 2 on Game Gear and I tried Sonic 1 on sms but the console on its own plays Sega Genesis games just fine I played a gain ground(bin file) and it worked great besides the fact of the screen being too small

Lol i saw that I actually have the console too I was comparing it with the original games and it does run a tad bit slower(Drill Dozer). When saving a game that it would tend to freeze but then continue after it's done saving (PokemonFR) and you could see the screen updating(like there's a line going through the screen very slowly up|)

Can anyone confirm if snes games run on this thing and if so how well? Im asking because this page says it will by changing the suffix to .smc

 https://funnyplaying.com/products/retro-game-console-32-bit-portable-mini-handheld-game-players-built-in-548-for-gba-classic-games

Even if they dont, ill most likely still buy it. But itd be great to have halfway decent snes emulation in this form factor

it's a subpar Super Nintendo emulator it's even worse than the Gameboy adv part, one thing is that the screen is way too small to display any of the words or Graphics properly .Mario Kart was not really running that great it it was frame skipping everywhere but it guess it was playable to some extent
Title: Re: New Retro mini: gba micro handheld
Post by: chevette on December 24, 2017, 07:18:46 pm
Plus the fact that it has only 2 versus 4 buttons. It stinks for NES, Genesis, + Super Nintendo as the resolution is no good for the small screen. It's OK for GBA (some games don't work at all (Iridion II) and some have bad frame skipping. And the screen is really, really small. I would not recommend this for the price (above $40).

Post by: Fishcakes on December 24, 2017, 07:59:47 pm
Thats a shame. I have no problem with the tiny screen, the gameboy micro screen is easy enough for me to read on. The crappy performance is a disappointment.

 Hopefully someone will like the device enough to optimize the emulators or create a more optimized os. Only time will tell i guess. Thanks for the info guys 👍

Got one today. Does play games moderately well, compatibility kinda sucks for the games I tried, emulation looks like frameskip 1-2. Build quality is actually really good. Got it for like $35. Not *horrible* but for the price, can't complain.

After doing some searching and playing around with my retro mini, It plays SNES, NES, GBA and SEGA MD/GENS (Must be a .bin rom file).

Another thing i have have found is if you plug it into a computer's usb and hold 'B' as you turn it on it recognises the device as the JZ4750 USB BOOT Device but won't work unless you either have the Drivers or the usb boot software. I have looked around the web but found nothing so far apart from fake sites with malware or trojans.

With this USB boot mode would there be a possibility to crack the firmware and install a dingux variant or even update the firmware to include native GBC/GB SMS/GG support?

Just a thought as it is an awesome little device.

(i have owned previously 2 Dingoos and install dingux to both this retro mini device looks as though it uses the same OS or firm ware)

That CPU is from 2005, what the hell?  ::)
That said, it should be very similar to the jz4740, so a port of OpenDingux is probably doable.

Got a card through the letterbox today so I think mine is waiting for me at the depot, if it's the correct item (and not something random I ordered from China at 2am 6 months ago) then I should have it tomorrow afternoon. If this thing does get hacked it would be nice to see a stripped down firmware with just GBA, GB/GBC, NES, SMS/GG and Lynx emulators on given the tiny resolution, ancient CPU and limited controls.

Looks like nice hardware and I have wanted something truly pocket sized and cheap for ages, even though performance might be limited lots of people still have a use for something like this.

you could try asking on /r/gameboy - there have been a couple of posts about this thing there already.

Post by: lemmywinks on January 03, 2018, 04:12:40 pm
Mine arrived today, as others have said performance is lower end of average. Smd and nes are good but suffer from resolution issues and poor control mapping, smd has vital buttons mapped to L and nes has A & B reversed. Gameboy is playable but is not smooth enough, as already said sms is a slideshow. GBA is variable, some games play well and some are awful, most are passable.

Hardware is nice though, can't fault it on build quality and it's a cool little handheld which is very pocket friendly. Btw if yours comes in Chinese as mine did (from FastTech) then press right 6 times, press A, press down 3 times and then press A again to get to the language selection screen.

Got mine today.  Charge was low so haven't had much time to mess with it yet...it's charging now.  Pleasantly surprised by the build quality and controls, though the L/R triggers are nothing like the front buttons.  They're super loud and clicky.  No SD card at all in it, so I guess none of the fasttech orders will have it.

Really looking forward to seeing if any of us can make it work better.  The screen and size are exactly what I need!
Title: Re: New Retro mini: gba micro handheld
Post by: jonothan on January 04, 2018, 01:13:53 pm
I guess I didn't actually hit post on the second reply I had typed up last night.

Turns out my unit is defective.  The microUSB port won't make good contact with any cable that I try.  That means that to charge it, I have to sit with it and hold the cable just right so that the red charging light stays on.  If I breathe wrong, it loses contact and doesn't charge.  Fucking infuriating.  I opened a case with Fasttech...my first order with them and I get to find out what their customer service is like.   >:(

So at this point, I'm not much help.  I did get some ROMs copied over to a microSD card to try them and see if results are any different than the crazy-named Chinese ROMs that are on the onboard memory.  Emulation performance on my ROMs seems just the same.  Some games it's okay, some games it sucks.  From what people are saying, there has to be some difference in the OS that's actually flashed to the thing.

I did try holding down different buttons as I turned it on, and my laptop would detect it when I plugged it in, but since the connection is so flaky I couldn't keep it solid enough to ever do any driver investigating.

I'm no help at all since this thing is busted.  :(

FastTech support is usually pretty good, sounds like you might just need to reflow the solder on the port. it looks easy enough to access so if you get to keep the unit you can try to repair it.

The battery is removable (a 1020mah BL-5C which are a pennies) so you could charge it with a generic pphone battery charger, the type with sliding pins.

With my shaky hands I won't be resoldering anything.  I actually already have 2 additional batteries that I think will fit it, but I don't have a separate charger for them so it doesn't help.  Even if I could, that wouldn't help with hooking the thing up to my laptop and exploring options for fixing the software.

I've opened a support ticket with FastTech.  We'll see what they say.  It's maddening.  I like the form factor of this little thing.  It feels great in hand, and I love that it has an easily replaceable/upgradable battery.

Until we get this thing cracked open and the software lined out, it doesn't perform well enough for me to carry it anyway.   ::)

FT support is the best of any China store I know of, but you still have to bear some things in mind when dealing with them. When you've opened a ticket, just wait. Every time you add some more info to the ticket it pushes it to the back of the queue. On the first response, depending who you get, they might try to fob you off with a $5 voucher or something. If you have no joy, just start a forum thread with @AnniePan in the title. She is something like a CS team leader and will sort it out for you.

They may refund you in full, or they may require you to send the unit back. They do pay for your return shipping. Make sure you use a fully tracked service and let them know how much that will cost before you send it. Sometimes the high price of return shipping means they'd rather just refund you in full for it instead.

Sorry you got a duff unit, mine just arrived today too. I haven't tried charging it yet because I'm at work and I'm worried about bringing down the entire network with Chinese malware :P

I got mine today and I'm in love with it! :D sadly though I have one of the not that great GBA emulation units (it's pretty noticeable when you load up an included mario game and just run straight. You'll notice the jittering).

As far as I know the most noteable differences between the different units are the (missing) logo below the screen and the number of included games. Some seem to have 40, some only 36.

My unit has no logo below the screen (which is the reason I might file for a partial refund. Hey, the logo is there on the Fasttech page after all) and 36 included games, in case you wanna compare.

edit: https://steward-fu.github.io/website/handheld/retro_mini/uart.htm
does this help with firmware dumping?

edit2: megadrive emulation is done via picodrive. after trying out a sonic game my sd card had a picodrive config file.

edit3: okay, holding down a and powering on seems to enable some kind of bootloader mode (you mustnt connect the usb cable though until after entering the mode). I'll try some different firmware dumping tools later and come back to you if i get any results

edit4: woops, apparently i forgot about the previous postings haha. so no real new discoveries on my side, but id be happy to lend a hand in and cfw development if i can

edit5: this post is getting long... it seems that the handheld is actually emulating a gba flash cart. when i tried the regular goombaGBC conversion it didn't run, i had to use the ez-flash IV emulation mode.

UART would give you serial access to the system, you could then terminal in and dump to removable storage, you would need root access. If the system is secure, there are ways of forcefully resetting passwords and the like.

I think the USB boot option is probably the easier path to get what you want. There are some utilities from ingenic that should include a way to dump. Away from my computer at the moment or else is give a link.

I am waiting on a 36 game unit from Fast Tech, this is incredibly disappointing to hear. Do you think it's possible to download the firmware from a good unit to replace the bad one? That would be a great band-aid until OpenDingux is available.

also the "bad" version still has some playable titles and the hardware should be identical. so when we get dingux on this little buddy it should all be the same

Mine is from FastTech and the emulation looks identical to every video I've seen including ones with the RetroMini branding and where people have paid $60+, there's no good and bad versions of these. I think that rumour came from reddit so take it with a pinch of salt.

Some GBA games are completely unplayable, most are fine although pretty much everything uses frameskip at some point to a varying degree. I know people who still swear the PSP does perfect Snes emulation and is better than anything out there, some people just don't really notice frameskip that much which explains why some buyers of these RetroMinis say they have great GBA emulation. There's also buyers' remorse - nobody wants to admit they got less than they hoped for.

I read a post on reddit (https://www.reddit.com/r/Gameboy/comments/7n49cg/retromini_coolboy_rs90_gba_clone_thingy_got_mine/drz3m5n/) where someone had 2 handhelds from different sources where one was noticeably better than the other. I know that is not at all a smoking gun but it is something.

I'm not sure how long a dingux port would take like if it would be months, I'm new here and too these devices. If there is a hot fix I would definitely be happy.

By the way Donkey Kong Country 2 GBA is a favorite of mine, hows it play on your device?

You can convert batches of GB/GBC games with this:

I know they aren't perfect, but i hope they may get hacked and end up with a better GBA emulator and maybe a GB/C emulator, too.

Thats all i really want to play on this anyway.  ;)

https://www.ebay.co.uk/itm/NEW-Digital-Camera-Carry-Case-Pouch-With-Velcro-Fastening-110mm-x70mm-x-20mm/282694248039?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

There's also other digital camera cases like this that would fit:
http://www.ebay.co.uk/itm/Black-Compact-Universal-Hard-Shell-Case-Zip-Bag-for-Small-Digital-Camera/141581029587?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

Just make sure the internal dimensions are 10cm x 7cm and you should be ok as long as the corners aren't too rounded.

this menu is looking pretty similar:

while the form factor isn't as nice as the retro mini device, it has more buttons and may have a newer/older version of the OS which might give us more insight.

Wait. So on this dingoonity forum there are the best hackers in the world and nobody has hacked this thing yet
Than retromini must have better protection than Apple and Blackberry together!

Why isn?t this thing hacked and can we remove the awful gba emulator on it? It just plain sucks!

We need to replace it with something good!

A lot of the performance has to do with the JZ4725B which is less powerful than the JZ4740 in the original a320. It's pretty old so I wouldn't expect miracles. GBA is probably the upper limit.


I know things will move on this device eventually,  but I only know of 1 person for certain that is actively working on it, and these things do take time.

@VanZan Absolutely agree!
Gotta admit tho... there are quite few systems this would be perfect for: GB/C, GBA, Atari Lynx, Sega Game Gear and NeoGeo Pocket/Color

all need about the same resolution or less and same buttons or less.

How lovely would it be to have a tiny dedicated handheld emulator... just for handhelds ; P

Well, Fasttech wanted me to make a video of the problem and upload it to some sharing site called WeShare.  I finally borrowed someone's phone and made the video this morning.  We'll see what they say now.  I'm thinking at this point if I can get my money back I'll just put it toward a Coolboy RS-97.

guys, we've been had! well not really, butt still. this os seems to be what pretty much all sub-$30 handhelds run, including the $23 pmp v. it even has the same gba sized display haha. although of course the form factor isnt as nice as our retro mini.
there are even handhelds running this os that have 320x240 screens, which might be better for everything not gb(a).
ill see if i can order some other models and compare them side-to-side.

I really think this player is neat.  I would like different options with the OS though like adding more emulators and different game folders.  Also Has anyone figured out game art?  I tried getting some USB drivers and starting in boot mode but was unable to get software.  If anyone can take some time to figure out how to get into the file-system on this thing I would really appreciate it Right now I am able to play NES, GBA, Snes,SMS, GB, and GBC but going through the file manager is cumbersome.

So, I've got my retro mini, from Fasttech, seems it's a fake version, it has chinese bundled games, and there's no "retro mini" on the marquee.

the charger that came with the device don't work, it's red light starts blinking and does nothing.

If i use another charger it only works if i turn it off, then on, then leave it as is, a big battery icon will appear, if i press any button to reach the main menu it stops charging.

would it be a faulty version? or the close is like that?

I have one on the way and would love to put some gb, gbc roms on it. Can you explain how you did it? I keep reading about goomba color alpha 6 but is that different than just goomba color? Sorry for the noob questions I just don't want to screw anything up. Thanks.
Title: Re: New Retro mini: gba micro handheld
Post by: lemmywinks on January 27, 2018, 01:41:24 pm
You use Goomba Color 6 Alpha which will convert your roms into a single GBA file, when you launch this you will get a menu (which is annoyingly slow) to choose your roms from. Because the menu is so slow (it waits to load a screenshot of every game) you're best converting them in small groups if you have a lot of roms.

GB/GBC runs ok on this, not great but just about passable.

lemmywinks, does it bug you that this device doesn't natively run GB/GBC games? I mean it has to, especially since it's modeled after the atomic purple GBC--it's just so, so weird!

Yeah my two favourite systems are Master System and Gameboy (these are what I played as a kid) so it's a shame they aren't natively supported. I can't be bothered playing GB on this as the menu is a chore to navigate and it makes the whole experience unpleasant. Unfortunate as I actually really like the hardware.

Sorry, wrong topic.  I was wondering if a 3.5mm to 2.5mm headphone converter would work for the coolboy rs-6.  It's a cool little device but I dont see me connecting it to a TV.  I'd use it with headphones on a train.  Not sure if this would work though.

hi
sorry just wanted to say that although not perfect the RS-90 and also the RS-97 is able to play some great and difficult to emulate roms pretty well. I have seen the RS-97 running the Golden Sun 2 at a very decent pace and the RS-90 plays most GBA stuff well (played some Mother 3 and it was perfect) . Yes some roms have problems but those i have seen do indeed work pretty well. I have got access to both handhelds so if anyone is interested in a particular rom please let me know and i can check it out. thanks guys keep it up!

edit: my sister just uploaded some random shaky video of GS1/gs2/fft/mother3 so if someone is interested you can see it on youtube if you search for rs-97 and sort by upload date. i do like these handhelds a lot, i can already see us fighting over it every day, luckily we got two so it should be so bad :)

I have one of these on the way.  I'm interested in hearing about what is running and how well it's running.

So basically you can have gb, gba, nes, snes, gg, and sms?  But you need to convert them to gba.

Do any of these run at full speed?  Which are running the best?
Title: Re: New Retro mini: gba micro handheld
Post by: lemmywinks on February 25, 2018, 02:45:24 am
Nothing runs full speed, NES in general runs ok but the buttons are reversed and the resolution is too small. SMD runs ok, skips frames though and the mapping is odd, GB via Goomba is okish but skips too many frames. SMS via DrSMS is a slideshow, SNES is poor.

GBA can be ok or unplayable depending on the rom.

I just snatched a Retro Mini from AliExpress and have been using it to learn how to use console-based music trackers such as M4G, and Furious Advance Tracker, both of which work fairly okay on this really inexpensive device. One thing that I've noticed is that most Pokemon romhacks I've tried don't seem to work. I've tried Pokemon Throwback, for example, and I just end up getting a blank white screen when loading the patched rom. The patched rom works fine in other emulators (vba on my desktop) and the base (unpatched) rom works fine on the Retro Mini. Has anyone else experienced this and/or found a solution? I'm assuming that it might have something to do with the 128kb save file, but I'm not certain if that's the issue. Also, some non-pokemon romhacks seem to working fine such as the Mother 3 English Translation patch.

i have the same problem with some of the roms. Luckily Mother 3 plays fine, and Mother series is the main reason i wanted this little gem. RS-97 for everything else, but RS-90 is always running Mother in my pocket

Been using mine quite a lot recently, converted all my SMS and GB/C roms to single GBA roms to bypass the rom selectors of SMS Advance and Goomba, it's much more usable now and pretty fun.

Annoyingly the device itself seems to have a bug where you can't press both shoulder buttons at the same type meaning no menu in Goomba, no weapon selection in Doom etc.
Title: Re: New Retro mini: gba micro handheld
Post by: ADY on March 04, 2018, 10:17:55 pm

Going off memory here but doesn't Doom for the GBA have a bunch of different control schemes? Is there one you could use that maps the weapon switching to different buttons?
Title: Re: New Retro mini: gba micro handheld
Post by: lemmywinks on March 05, 2018, 12:15:52 am
Probably, it doesn't run well enough to bother and I played the hell out of the GBA Doom games so the R+L weapon select is hardcoded into my brain!

BTW does anybody know of a GBC>GBA converter that supports savestates and rund on this? Goomba Color Alpha 6 runs fine but savestates are disables and Goomba Color 12 doesn't seem to load roms on the RS-90. Saves work fine with regular b&w GB roms using Goomba 2.0.

I remember someone talking about a particular setting but I can't find anything on the Goomba frontend, just the annoying splash screen option.

Good evening to all, my software RMPatcher (RetroMini Patcher) is ready !  I will need beta tester just to be on before the final release !
The software is simple, it converts the roms .gg and.sms in gba (reworked by me 8)) to use the best of the retromini :)
No more worries about sound or frames images (or very few ! ;))

Beta test available in MP

Hello,

I'm wondering about the RMPatcher and the NES Patcher.  How has the testing been going?  If everything is ok, I'd like to try them out.  I just got my RetroMini today.  thanks!

SMS Advance as suggested by the poster a few days ago actually works pretty well, it uses frameskip and there's the odd slowdown but games are still playable:
https://www.zophar.net/consoles/gameboy/sms-gg/sms-advance.html

I converted my roms individually. I love the Master System so it's great to have it on this device which travels to work with me every day.

I guess I'm slightly confused about how to get roms working.  Are there two ways? 

For example, convert an SMS rom to GBA format and it plays through the GBA emulator.

Or

Use an SMS emulator.gba and add sms roms to it

Is this what is happening? 

Title: Re: New Retro mini: gba micro handheld
Post by: lemmywinks on March 05, 2018, 02:27:04 pm
It converts the rom(s) into a standalone .gba file, like a prepackaged emulator and romset that a GBA can see. I did mine individually and renamed them accordingly (eg "SMS Golden Axe.gba"), however you can convert a whole batch into one .gba file and select them from a menu after launching it.

These converters are from the GBA flashcart days, it's basically two layers of emulation on the RS-90 - a MIPS soc emulating a GBA emulating an SMS. Same with Goomba, no native emulator so you use GBA flashcard converters.

Thank you for clearing that up.

So I'm guessing there are different converters and Superbenoit made one for beta testing?

If it's not too much trouble, could you list the best converters for each system (nes, Genesis, ect) How many systems can GBA emulate? 

Thanks again!  I'm looking forward to getting it set up.

Post by: lemmywinks on March 05, 2018, 05:00:31 pm
I only really used my GBA for emulating SMS back in the day, from what I remember it didn't handle SNES adequately at all so I would stick to 8 bit systems. There's probably more knowledgeable people on here when it comes to GBA flashcart emulation. Briefly tried to use PocketNES on the RS-90 but it didn't load the menu, maybe someone else has had better luck:
http://www.dwedit.org/gba/pocketnes.php
NES played natively has horrid scaling and reversed buttons.

Hopefully this system sees some development, shame about the shoulder button issue preventing menu access. Maybe Goomba and SMSAdvance can be modded to suit the RS-90 a little better, perhaps this is what SuperBenoit is doing.

One of my pet hates with this system is the big delay when writing a savestate, I sometimes play games in very short bursts so I need savestates. So far only Goomba (not Color) has working savestates.

There seem to be a bunch of versions of this now on eBay. I?m thinking of getting one since it?s at about $35 shipped now, but I don?t know which one to get. I see with logo, without logo, black, clear/white and I?m not even sure the images are reflective of what each seller would actually ship. Any way to reliably tell if you are ordering the ?good? units versus the ones with poorer emulation performance?

Yeah,
I missed the boat on testing because my unit was still in the air.  A lot of people jumped on it... But I don't hear crickets either.  Haha. @jutley is pretty active so surprised not to hear back from him.  He may be focused on the rs-97.

I've been messing around with the old emulator injectors.

I got colecovision working through cologne.  I also got the arcade game punch out working.

I couldn't get pocketnes to run.  I put multiple games on the smsadvance emulator.  Noticed a good amount of flickering at the start of games...  My have to try out the version of smsadvance on zophar that @lemmywinks posted and add them one by one... 

Surprisingly I couldn't get goomba color working either. 

In a few posts back @SuperBenoit linked to an NES injector and also the "thingy" which was a sms/gg injector.

Definitely interested in hearing about those 3.

I see, but the testing that you did for @SuperBenoit with his sms/gg converter.  Did those games run better than with the regular smsadvance converter?  If you didn't compare... How did they run in general?

The SMS Advance I used can do bulk romsets too btw, I just did them individually to save time when selecting roms. The Goomba for normal GB is Goomba 2.0 here:
http://goomba.webpersona.com
For GBC I used Goomba Color Alpha 6:
http://nintendo-ds.dcemu.co.uk/goombacolour.shtml

Goomba 2.0 is able to use savestates, even though the menu is inaccessible because of the L&R issue you can use R&Select to quicksave and R&Start to quickload. Unfortunately doesn't work for GBC roms.

The Jz4760B is mostly an hardware improvement on the Jz4760 with smaller die, better power supply, controllable I/O drive strength, OTP unit and internal buses improvements. The IngenicJz4760B is pin to pin compatible with the Jz4760 except for a slight tweak needed for OTP (if used).

I've picked up some spare original GBA shoulder buttons, cutted and trimmed some of the plastic and with two drops of super glue the shoulder buttons where a problem no more 8)

So, maybe this has already been said before, but I encountered the following:
- RS-90 GBA emulation of the pre-installed games sucks bigtime (got a FastTech unit without any text under the screen). E.g. the chinese version of golden sun runs horrible (a lot of frame drop and sound stutters)
- However, when I run extracted .gba roms from the microsd the experience is MUCH better! Golden Sun still has some framedrop and a bit of sound stutters here and there but defenitely playable and even enjoyable!

Did anyone else also noticed this?
I looked around but did not find any way of replacing the roms on the internal memory. Anyone any succes with that?

Looking forward to a better emulators / opendingux for the RS-90 ^___^

Instead of using Discord for such chat and important information possibly getting buried, I think it may be better to chat about in a place where development happens. One such place is here: https://github.com/SoulEst/OD_on_JZ47xx I made it so that we can contribute ideas and code to further the development of OpenDingux on all Ingenic JX47xx devices.

It was not smooth playing on the device, some frame issues. The device was getting stuck if i play a video and then try to return to main menu (by pressing the B button). Then i had to switch it OFF and ON.
The empty space on the back could do with a nice product label....so i made myself one of sorts  :P

Note since this picture i have returned to the store and have bought a black dock as that seems more suitable to match the RS-90.

I'm trying to use the goomba to create rom gbc for gba, but when I do the whole process the screen of the Rs-90 goes black. Help, if anyone can make a rom available for testing, thank you.

Where are you getting the goomba from?

I was getting a black screen until I tried this goomba version:
https://github.com/gnmmarechal/EZerClient/tree/master/EZGoomba%20Frontend/EZGoomba%20Frontend/bin/Debug/Emulators/GoombaColor

At least I think this is where I got it. I'd just attach it, but the forum only seems to allow text and image files.

You still can't save properly in this version because the L and R buttons do not work. You have to use snapshots.

Use Goomba Colour Alpha 6 for GBC and Goomva v2.0 for GB roms. With Goomba v2.0 you can save and load a savestate using R with Start or Select, unfortunately this doesn't work with Alpha 6.

Hi All, just joined here and bought a retromini recently, very excited about the capabilities of this little device. I live in China so i'm guessing I paid alot less than most of you for the device, and I'm wondering whether the device has many clones as many of you are mentioning that it has a  jz4740 chip on it, I opened mine and found a samsung chip on it, here is the data sheet http://www.alldatasheet.com/datasheet-pdf/pdf/97972/SAMSUNG/K9F2G08U0M.html

notice there is also a space for an extra IC that has been left of the board, I wonder what functionality it may have been intended for. Tried to inquire around about which factory is producing these but no luck so far

that's the flash memory i think. some of them are hynix and others are samsung. you have a JZ4725B in there under the screen just like all the others.

how much did you pay, out of interest? cheapest i've seen sold locally in China is about ?20-?22 ish. Fasttech price shipped globally is about ?26 with a discount code.

Post by: oxxie on April 23, 2018, 04:50:28 pm
Ah I see, I thought the datasheet seemed to indicate it was flash memory, i'll take a look under the screen tomorrow. I noticed the board on steward fu's had a hynix chip, I guess its a cost cutting measure. The vendor sold it to me for roughly equivalent to 18 pound, It was in a wholesale market in shenzhen. They initially asked how many units I wanted so I imagine i'd have gotten an even better deal if I'd bought in bulk. The rs-97 was quite reasonably priced too roughly 30 quid. I bought a coolbaby as well, its the smaller sized lower quality looking gameboy that only plays preloaded nes games

Just out of interest how much was the CoolBaby RS-6?

I got one for ?10 delivered so it's interesting to see how cheap it can actually get!
Title: Re: New Retro mini: gba micro handheld
Post by: oxxie on April 24, 2018, 05:15:52 am
Not too much cheaper, mine basically cost ?9, although again if I'd have bought in bulk obviously it would be cheaper. Last night I tried plugging my coolbaby into my laptop in the vain hope that the flash memory might be accessible from the USB, but when I plugged it in it basically shut off my laptop. It seems the electronics in the thing must be pretty shoddy if they haven't put any surge protection in

I purchased 2 of these. one in a smoked body and one in a frosted body.   The smoked model came with English games and you can get to the folder when connected to a computer using usb.   The frosted one has Japanese games and does not permit accessing the internal flash.

I have checked and disassembled both of them and the boards are identical.  It all comes down to the software load.

the smoked grey model provides the following modes when you hold the corresponding button while turning on the system while connect via usb
smoked version - Japanese games
HOLD Select -  Boot loop
HOLD Start - INternal storage
HOLD B -  jz4750 usb boot device
HOLD A - BLACK screen, nothign on button release

HOLD R - nothing
HOLD L - reboot loop

HOLD Left - nothing
HOLD Down - nothing
HOLD Right - nothing
HOLD UP - nothing

Internal storage is 208MB

Scottvb the 2 handhelds that you disassembled did they have the same memory chip? my flash memory chip was samsung branded and others have reported hynix, I wonder if that has anything to do with the issues of accessing the internal memory via usb

I also have the version with the frosted case and 40 english games, I will test your start button method tonight and see if I can access the flash memory

this seems to be the driver, I haven't tried it myself as it connected fine on both my mac and pc. I connected the usb first then hold down start and power on the device, I was able to access the internal flash, I removed some of the roms that were preloaded and replaced them with some others, in the system folder there is a system.cfg file but it just has a single line of garbled text.

Hey Oxxie!
you are very correct.  the smoked one has a Samsung Memory chip with english games and a Functioning START+Power to access the internal storage.   the Frosted has a Hynix with Japanese games and no access to the internal storage.

as a side note to others on the board I was able to use the 64bit drivers to connect to my Frosted Hynix model and perform a dump as listed in other posts.  I dont know if i want to risk trying to flash the smoked samsung onto the Frosted Hynix. or if the memory addresses even match up.

I also found that you do not need to dissemble your retro mini to to see the flash chip. if you remove the battery you will be able to see it through the case.

It's not been hacked yet as far as I'm aware, why would anyone bother when there's the RS-97? The RS-97 has a faster SOC and a massive amount of development on custom firmware. Considering I paid $47 for my RS-97 compared to $59 (converted from EUR), the Mars Gaming MRB is simple cashing in on the unfortunate uninformed. I don't know why, but even on Ali-Express the Retro-mini (same as Mars Gaming MRB) is only a few $ less than the RS-97 on Ali-Express ($42.15 for Retro-mini, $47 for RS-97). $4.85 extra for the massive performance benefits of the RS-97 is a no-brainer.

A reliable source told me that this thing is unhackable.

I see. Kind of too bad - the device is actually quite ok, smaller and much cheaper than the RS97, and with up to date emulators, it could be a really nice GB/GBC/GBA handheld (GBA is pretty ok even with the stock firmware, but GB/GBC are a really mixed bag). Maybe even the horrible NES/SNES scaling issues could be fixed somehow.

I think I will keep one in a drawer just in case this gets picked up at some point.

I picked up a Retro Mini last week. What a great little device. Not really a classical emulation handheld (I've had them back to the GP32blu+), I really like that it doesn't have a bunch of sub-menus, just games. So I've narrowed mine down to a dozen or so GBA, SNES and Genesis titles. I've deleted hundreds that just didn't work well enough or I have no interest in. The native save-state support makes quick sessions entirely feasible. For Advance Wars I can make genuine progress with as little as 5 minute windows.

I picked up a Retro Mini last week. What a great little device. Not really a classical emulation handheld (I've had them back to the GP32blu+), I really like that it doesn't have a bunch of sub-menus, just games. So I've narrowed mine down to a dozen or so GBA, SNES and Genesis titles. I've deleted hundreds that just didn't work well enough or I have no interest in. The native save-state support makes quick sessions entirely feasible. For Advance Wars I can make genuine progress with as little as 5 minute windows. I'm surprised Pilotwings works as well as it does. It will never take the place of my XD but I'm finding I'm using it more.

May I ask you which games you have put on it?

It's a shame they focused on GBA really, if it emulated just SMS, GG, NES and GB/GBC out of the box and did them well it would be much better IMO, even with scaling issues on the non handheld consoles. Still it's enjoyalbe to use and even with a little Palm case it takes up no room so it travels with me all over.

I had a genesis rom in the wrong folder so it didn't show up in the game browser but when I went to the file browser and selected it it let me try and run it. Instead of booting the emulator it just went black and dumped me to the main menu.

Could it be that the handheld runs its executables as .bin files? could something be done here?

Forward Solutions just announced plans to release a RetroMini 2 on r/gameboy  (https://www.reddit.com/r/Gameboy/comments/94d6xr/retromini_2_the_long_awaited_revamp_to_the/). It's basically a new handheld with a 4:3 screen, 4 face buttons and more focus on the SNES.

Quote from: Forward Solutions
Hello Everyone,

My name is Daymon Schultz, CEO of Forward Solutions Inc. and the Owners/Creators of the RetroMini.

We are excited to announce the next generation in RetroMini and would like your help in offering up suggestions for what you'd like to see with this new device. After receiving a large amount of critical feedback on our original RetroMini console, we felt it was necessary to begin developing a 2nd version. The RetroMini 2 aims to fix a slew of problems found within the original device:

25% Larger Screen
25% Increase in overall size
Increased size to the rear triggers for better functionality
Addition of XY buttons for full SNES support
Developing native GB/GBC support
Better internal components for smooth Emulation and to reduce lag
This is the first time we are reaching out to the community to really get an idea as to what everyone looks for in a GB emulation console. Any feedback would be greatly appreciated and when the device is fully released, we will be sure to thank the community in a generous way.

We have just finished up the mould process and have begun work on the PCB board. Here's a sneak peak at the current mould: https://imgur.com/a/0rnD2Ra
Thanks again for reading this post and can't wait to get the RetroMini 2 released!

I'd also like to address the elephant in the room surrounding the original RetroMini. I've come across numerous reviews on YouTube, Reddit, gaming forums etc. in regards to the RetroMini and the lag/build quality of the devices. What many are not aware of, is that the RetroMini was knocked off. We were unfortunately late in getting our Trademark which led to Chinese manufacturers distributing the product to unauthorized resellers/distributors under our name. It was also discovered after doing a tear down of these knockoffs that they were built with inferior parts, causing the device to function way under our strict guidelines (we understand that there will always be some form of minor lag, but these knockoffs were unplayable).

To ensure you are buying an authentic device, it must be purchased through www.retromini.com. We have NO distributors, NO resellers, NO Amazon Listings. Once the Trademark has been made official we will do our best to have these sellers taken down to ensure everyone moving forward receives an authentic, functioning device, with full customers support from our team.

If you have any questions, please do not hesitate to email us at contact@RetroMini.com

It's unlikely this will be any improvement at all. Ingenic SoCs will be hard to get by (expect some lame ARM SoC without OpenDingux support) and the screen wasn't actually detrimental (having a GB Micro screen is awesome). To me the original device simply looks like a private label device based on an existing design. Hell, it even runs ?C/OS-II like the Dingoo A320 with a SoC from 2005. There is no way any lag can attributed to using "inferior parts". The GB Micro screen is freely available, the battery is just one of many knockoff Nokia style batteries and the SoC in these "knockoff" devices is still the JZ4725B.

There is mention of "Developing native GB/GBC support", which will probably entail taking some open source emulator while keeping it closed source. The only reason the RS-90 has any issues with GB(C) emulation is because it uses Goomba within some gpSP GBA emulator fork.

I might as well make a handheld out of Creator Board Ci20. Those are pretty easy to come by.

I will probably start working on that. Since it has some linux support already out of the box and Dingux can be ported to it.

It definitely sounds fishy as they talk about bad Chinese manufacturing being the reason for bad build quality/performance yet they are selling the same product on there site. If there version indeed runs better and has better build quality you would think they would want to show a video of there performance next to the supposed rip off version. It would be cool if they were telling the truth because this is a very cool little handheld but it doesn't sound like its legit.

These clowns are clueless! Maybe I'll make a badly 3D printed GB knockoff shell and pretend I'm a console company!

Plus even if they were serious they're still oblivious to why people like the RS-90 - because it's cheap and tiny yet still usable. If the makers (the actual real life ones, not Backward Solutions) had any sense then they'd open it up to community developers and let it realise its potential. Instead we have this familiar struggle where Chinese manufacturers want to protect their stolen code at the expense of their profit margins. Almost like they have no idea why handhelds such as the A320 sold so well in the first place.

Wouldn't a ARM SoC provided it could support linux be a good thing? It could presumably take advantage of ports from the old GPH handhelds, open pandora and the rasberry pi depending on the specifics.

Most ARM SoCs have a terrible reputation with regards to upstreaming drivers into the Linux kernel. Just think about all those Raspberry Pi clones and which kernels they are stuck at and what binary blobs they depend on (WiFi/GPU/video decoding/boot loader/etc).

Porting software is not easy. GPH based software is probably suffering from a lack of maintenance and/or a lack of sources. It also came from an era where people didn't care about well written ports. If you want to take a look at what a proper port consists of then I'd suggest you to check out the GCW Zero software porting guidelines (http://web.archive.org/web/20150920144451/http://wiki.surkow.com/Software_Porting_Guidelines). I can assure you that the majority of the software thrown onto these forums doesn't meet them.

I'd definitely purchase one of these devices if somebody can get some proper homebrew on it.  The NES, GameGear, GameBoy & GameBoy Color, Sega Master System, and Atari emulators, would really do some justice to the RS-90 (even if that's all it can run @ 60fps).  Is anyone actually working on this?

I've been thinking a lot about this little device and what could be done with it once it's cracked open - as we all know, it's pretty nice hardware, just utterly crippled by the software and interface.

The 240x160 screen is an interesting one, and the current menu is serious hampered by it - only showing 6 games at a time, for example - but it's not like designing for phones where everything has to be at least finger tap sized - interactive objects can be small, they just need to be distinct and clear - and then it hit me, the sprite based art is great for this kind of thing.

So I started mucking around with a mockup for an icon based grid, rather than just a list of roms, and I kinda like how it looks, especially for iconic characters.

The idea would be that each system has it's own colour scheme - so GBA silver and purple, master system black and red, etc, so it would always be clear which system you were selecting. a grid of tiles on the left, the currently selected objects on the right.

Thanks! I'm not completely settled on it yet, it could definitely be clearer as to a users position in the grid. Ideally you'd give people the option to choose between a couple of views - rom list, icon grid, maybe something that emphasizes box art...working on it!

And where do you find the icons?
Honestly, I've just been cropping from screenshots. It'd be fairly trivial to set up a site with a DB of icons though, or just talk to the folks at one of the several game DB's to see if they'd allow a category of icons.

There's a new update on the blog: https://zcrc.me/

RTC is not working?  How important is RTC in GBA games?  I was planning to use mine for Pokemon games too

This is amazing, possibly one of the biggest bits of progress i've seen on this system.

Yeah, great news.

It's actually not that bad - the UI is simple but functional, and gba games run pretty nicely right out of the box (even proper saves are supported for games like Final Fantasy VI and Wolf3D). Adding direct support for gb and gbc would be great though (currently needs ROM conversion via Goomba), and NES/SNES games would really benefit from being cropped instead of stretched.

Too bad Lost Vikings don't work (the device just restarts after a few seconds), and the handheld is too slow to run Doom and Doom2 at any acceptable speeds.

I finally caved and bought an RS-90 "Retro Mini"... it arrives within 24 hours.  I would like to help in the development of a CFW for it, but I am not as technically savvy as pcercuei.

So far, I have the USB Burn Tool 1.6.1 with the drivers, and have been reading over the English JZ4725B devguide (from 2013).  It looks like pcercuei has not been able to get Linux to output to the color LCD screen, yet.  Is it possible that someone could hack the driver from the NAND dump and integrate into OpenDingux kernel?

Or, what can people do to help the progress? ( now that pcercuei is getting further (and looks to be one of the only people actively able to hack with progress) )

That's assuming it uses Linux though and it's most likely inside of the precompiled kernel anyway if it does use Linux. (not to mention kernel symbols being different etc...)

Get the LCD & Audio to work but so far, it seems pcerceui has not published his changes yet.

Btw pcerceui, once you get LCD & Audio working (which does not sound simple...), if you ever decide to work on the custom firmware, i would advise that you use musl rather than uclibc for the libc. I've only had issues with uclibc-next, at least on the RS-97...(Musl was only a beta in buildroot 2014 but that has since changed)

It's nice though that the RS-90 will get a newer kernel, i'll closely follow what you're doing with it.

There are some user made icons available, but they don't cover all the games.  Maybe box art could work instead?

Sadly not - box art at 32x32 really isn't clear at all. Here's an example
(https://i.imgur.com/g70bwgP.png)
You could scale things up, but then you'd show less games...and we're back to the original issue.

Anyway, I tweaked things a little bit, trying to make it a bit clearer what game and system were selected, and had a look at what might work for the master system.

No, the original OS is not Linux, and even if it was, this would be impossible. I'd need the sources.

How do you get the RS-90 to detect as an xburst device?  I have all the files ready and I just need to flash them.

Tried powering on and press B.  Maybe my VM is not detecting it with USB.
Yo yo yo!!  This is great news and progress, too!  Have you tried the ingenic tools?  I remember seeing some documents to flash the very files you are talking about.  I'll look for them, but maybe you'll be able to get there faster?  PM sent.

Just wanted to add to what people have said previously here:

There are at least 2 different RS-90 RetroMini's.  From the same seller, I have received both types.  The one with the Samsung chip I have runs much quicker in all emulation than the one with the Hynix chip.  The only way to tell the difference between the two is the chip under the battery compartment, as said earlier in this thread.

Using the same microSD card, the Hynix chip takes about 10 seconds to load the Romlist where the Samsung chip takes about 2 seconds.

I believe it has been asked before, but does anybody know where to reliably get the Samsung-chipped, faster-emulating RS-90's?  Don't really want to end up with any more slow-mode ones.  I feel sharing this would be good for the RS-90 community.

It's not like the samsung ones are much better, for some reason gba games won't run anymore on mine-- they just boot to the GBA bootloader with a messed up nintendo logo no matter what.

I have the Hynix chip in mine and the roms folder loads pretty much instantly.

I am using a SanDisk 32GB A1 microSD card with over 2,900 items to be loaded into the list.  The RS-90 with the Samsung flash chip I received is quicker in every way.  For instance, the introduction level of Castlevania: Concerto (with the armor that chases you) runs smoother on the Samsung chip than on the Hynix flash chip RS-90.  Still, games like Star X do not run fast enough to play on either.

The most obvious slowdown with the Hynix flash chip RS-90 is when loading a large romlist.  There is just something about the Samsung flash chip RS-90 that makes everything quicker.

Title: Re: Retro mini RS-90 gba micro handheld

Yes, the internal NAND roms on the first Hynix ran slower than the Samsung.
Amazingly, I have now received a third Hynix RS-90 that now works the same as the Samsung RS-90.  This is confusing.

interesting - any particular game that would allow me to easily find out whether I have the faster or the slower version?

also, can you check whether you can run Lost Vikings on the faster device?

Hey, if you want to ensure that you receive a Samsung-chipped RetroMini, you can do so by putting a note in your order through www.retromini.com. I will personally sift through our inventory to ensure you get the Samsung chip. As for the confusion on why some devices have Hynix or Samsung, that's related to whats available immediately to us at the time of manufacturing and the costs associated with purchasing the chips.

If you have any other questions, please let me know.

Difficult to tell based on what game you're playing. Best way to tell what chip you have is by removing the battery and taking a flashlight to the unit. You should be able to see the chip logo at the top of the battery compartment.

Any chance you could try Doom2? That one is absolutely unplayable on a Hynix unit, so it should be easy to see whether it runs better on the Samsung unit - if it runs considerably better, I might consider buying directly from retromini com (as the price is pretty steep there, they can be purchased on ebay for half that price, shipping included).

Ran the test on both Hynix and Samsung chipped units, both are unplayable. We do have the RetroMini Pro slotted for release in October. I'll have a few units available to test by mid-September. I will run Doom 2 on that and see if it nets better results.

As for getting them cheaper on eBay you are correct, however those are knockoff units. To ensure you are getting a proper warranty and customer service, they would have to be purchased directly through our site. Come Jan/Feb of next year, all RetroMini listings on eBay, Amazon, and other knockoff resellers websites will be taken down due to Trademark Infringement. Get your cheap units now while you still can!

Honestly if you want to run Doom and have decent emulator performance then just grab an RS-97, it's almost as compact and has native Doom engine ports. The RS-90 is pretty cool for what it is but no way is it worth $60 or whatever they're charging, the Chinese reseller prices are about right IMO.

Pretty disappointed with the emulation on this device wondering if I can replace the motherboard with a pi zero or something.   Or may end up getting a backlit GBA on ebay or RS97.

I mainly just want to play pokemon GBA and fire emblem

You could certainly try putting a Pi Zero in the shell. I haven't heard of a kit or anything like that for you to use, but there might be something like that out there.

The RS-97 seems to do very well with GBA emulation, once CFW is installed. One thing to note is that some newer units, labeled 1.0S under the battery cover, have incompatibilities with CFW that haven't been fixed just yet. (The preferred GBA emulator, regba, doesn't run, which leaves you with gpsp.) Also, the RTC stops when the unit is powered down.

Hi, guys!
I found a way to use full-screen NES roms on the RS-90.
You have to convert NES ROMS with EZ CLIENT 3.25.

In addition, this program also converts Turbografx-16 and GB roms (no fullscreen).

I found a Flashcard Gba OS that support GBC\GB Emulation (http://krikzz.com/pub/support/everdrive-gba/OS/) , but you have to adapt it to the rs-90.

Pogoshell run on our Retromini RS-90?

Rs-90 is the best.

Hi guys, I found a way to play GBC roms on our RS-90 more smoothly.

I converted GBC rom into a GBC multirom with GBC-X-TOOL (an old GBC flash card software).

Later I converted gbc Multirom into gba with EZ Flash 3.25.
The emulation is faster and less troublesome than the crap of goomba color.

My RS-90 has died  :'(  Was playing some SMS and it hung, now when I switch it on I get a black screen, power and charge light are functional. Tried it with a spare battery and I get the same result. Crazy busy tonight so will have to open it up when I get chance.

Oh well, it's a disposable little thing and if it is dead I can steal the dpad for my RS-97 without feeling guilty.

Mine does that sometimes. Try taking out the battery, putting it back in and playing with the angle a bit. Also you can try playing with the volume wheel when you are powering it up. I do not know why doing these two things helps when mine has the light on but a black screen but for some reason it does. It most likely is happenstance that this works but if you do open it and find the main problem please do post here and let us know.

Well I got in after tonight's gig and read your post, turned it on and it's alive again! Will open it up and reseat everything tomorrow and give it a clean. Tbh my RS-90 has a hard life than most as it lives in my work bag, even though there is a little pocket that it fits perfectly into and I always keep it in a padded case I guess it gets banged around a bit. Glad it's still functioning though as it's such a handy little thing.

Congrats on it being alive. It really is a cool device. I love its size, its a cheap alternative to a gb micro and its frame rate is not too bad. Hopefully they make a new one with a little better hardware and software. I take this thing everywhere and that's saying something with all the handhelds I have for emulation.

Could you please upload it Mega.co.nz ? (you will need to register a free account)

Nothing like Bumping a thread that seems to have died. I just got this unit. (Late to the party I know, but for $25, I figured what the heck.) I know everyone has been focused on getting Dingux going which seems to be a losing proposition without a lot more work. I am honestly curious if there is any way to get some more of the community made Dingoo A320 Native software working? It seems those needed to be in either ".sim" or ".app" format. For the life of me though I can't make them run on this little thing. If anyone had any advice on to maybe get any of that going, I would love to hear.

Does this give you access to the area where the emulators are actually installed? If so, there are some good options from the original Dingoo A320 That should be portable into the system.

@Great Crippler Lets hope so... the A320 is one of my favorite systems... Hopefully they can port the "3D Games / Interesting Games" section... 7 Days is a great Resident Evil clone... There was a shooter too similar to the Raiden series :)

So, in an attempt to get in over my head. If I were to add on the port to my current unit. Would I gain any benefit?

Probably not, unless you intend to use it for debugging or development purposes.

No, sad to say that's all a bit over my head. I just want a way to add PCE emulation. This device just screams pocket Turbo Grafx to me.

I quite fancied it for some of the great 2 / 3 button arcade games Double Dragon, Bad Dudes, Robocop, Turtles, Simpsons etc...

Now my 3 year old daughter uses it for Mario and Mickey Mouse games... Oh and Big Hero 6 the series... as a pocket media play it isn't too bad

Right, until work from pcercuei and others lead to a fully functional Linux kernel. That will open the door for CFW and native ports of other emulators and software.

Don?t bother playing other stuff than GBA. That sucks on this awesome machine.
So far no one in the world has been able to hack this system, its copy protection is out of this world!

Quick list from my own testing:

GBA: Decent. Slow downs and compatibility issues abound, but overall mostly enjoyable.
GB: Roms must be converted using "goomba." Results are hit and miss, but overall pretty good.
GBC: Roms must be converted using "goomba color." Also hit and miss, but a lot more miss than GB.
NES: Bad aspect ratio (Screen looks squished.) , but runs well enough. "pocketnes" can fix the aspect ratio to a point on a lot of games, but requires some work, and is a bit hit and miss.
GENESIS/MD: Bad aspect ratio (Screen looks squished.) , but runs pretty well.
SNES: Bad aspect ratio (Screen looks squished.) Runs decently on a lot of games, but with 4 buttons, your mileage will vary. Special chip games are also pretty sub-par.
SMS/GG: Roms must be converted using "SMSadvance" Haven't used this much, but i imagine results will vary a lot game to game.
PCE/TG16: Roms can be converted using "PCEadvance" but almost everything i have tested has been unplayable.

Also SMD has control issues due to the lack of 3 face buttons, having a vital button mapped to L/R on the RS-90 is a chore. NES also has A and B reversed.

SMS is ok, not smooth but playable and compatibility is ok.

I prefer the Bittboy by quite a margin as it just provides a much better standard of emulation. I mainly want GB, GBC and SMS and although the RS-90 does all of this the performance just isn't up to standard as it goes through 2 layers of emulation. Games are playable but not exactly smooth, I got my RS-90 for short sessions as it lives in my work bag so it's fine for this, I wouldn't want it for my main emulation handheld.

It's always frustrating with cheap Chinese handhelds as they're 80% great with annoying little niggles, you would think by now they would be able to release something that can perform simple tasks like 8bit emulation especially as it's not like they're writing the emulators themselves. This is why I like the original XD so much as it just doesn't have any real problems.

I feel like this is a comment trolling me? But what the heck. The reason is not that I don't want one. (Though it's not high on my list) I want a small very pocket sized handheld with a Gameboy style setup. I have gone through a lot of options. From a size standpoint, the RS-90 is ideal, as it fits right in my pocket inside a small bag (Old Oakley Sunglasses bag to be exact.) It just doesn't run that well. Here is a completely unsolicited list of things I have tried, and moved on from. (I imagine I missed some, as this is just off the top of my head, but yea.)

PsP/Go/Vita/etc: PsPs are fine, and the GO is close to the right size, but I find it causes hand cramps.

Nintendo DS/3DS/etc: 3DS units aren't small enough, and DS Lites have crap emulators.

GBA/SP/Micro: A GBA SP AGS-101 with an Everdrive is actually what I usually carry with me. PCE is bad, but playable with some work on a lot of games. I like the SP a lot, but I want something a little more shaped like the RS-90 or Bitboy. (The Micro cramps my hands)

Dingoo A320/380: Almost works for what I want, but I find even between the Stock OS and Open Dingux that it's just kind of buggy, and locks up a lot. Constantly finding a pin the poke the reset button is irritating. Years worth of no updates or community, so not really worth the effort.

GCW Zero: Cost is too high for performance, and the units I have played on while showing solid emulation, have really poor D-Pad, and button design. I have heard the 3D printed buttons help, but that's a big drop of cash for a maybe it improves it enough, and is still a touch larger than I want for my pocket.

GP2X/Wiz/Caanoo: Had a couple, and haven't liked the button quality, and performance is REALLY hit and miss.

RS-97: Again, very close. Runs well, decent size, but I have had 4 in hand. Wildly inconsistent build quality, though the one consistency is "Cheap."

Tapwave Zodiac: Cool design, but doesn't run very well.

Android/IOS: Functional, but haven't found a pocket controller combo for my phone that I really like for taking with me. Clip for my PS4 controller is great for playing at home.

Odroid GO: Nice little device, but no PCE, and with only 2 buttons, I imagine the device has seen most of the development that it will.

Arduboy/Gamebuino/etc: Cool Devices, but not really emulation Handhelds.


TL;DR: Love open source handhelds, and am just looking for that "Ultimate" very pocket sized unit. I take the RS-90 with me a lot, so I have spent more time with it than most, and keep hoping a CFW is possible.



@lemmywinks Thanks for the comparison. I am going to put in an order for the new Bitboy. I want to give it a shot.

No, I am serious, thanks for your long answer. I have many many many handhelds (even a PCE GT) and am in the same position as you, searching for the ultimate one that plays 16 bit games perfectly.

I agree with you on the gcw zero ( I have one ), the machine is awesome except for the d-pad.
My favourite handheld now is the PSVita (original one) because the oled is awesome (but 16:9) and the dpad is just the best ever!

Not without some downscaling though, at least for NES, SMS and PC Engine.
Honestly, apart from maybe GB, GBC, GBA, PokeMini, Wonderswan (almost a perfect fit), Neo Geo Pocket, Lynx, Game Gear, Supervision, Atari 2600, Odyssey 2 and Intellivision, everything else will require some downscaling and/or cropping.
And without IPU, ports are going to be painful... But let's see how it turns out.

Decided to adapt Quake for the RS-90's low screen resolution (240x160) as a celebration for the CFW :

And here's the source code :
https://github.com/gameblabla/sdlquake (https://github.com/gameblabla/sdlquake)

I don't plan on getting the RS-90 though, 240x160 is too low for my tastes and the low-end hardware makes it worse.
It does make it the perfect device for GBA though. (I just hope that performance of reGBA isn't lousy on it.)

Custom firmware might be a misnomer. This device isn't getting a modified "custom" firmware like the RS-97. Rather, the hardware needed to be reverse engineered. This consisted of deciphering LCD and memory timings, porting the bootloader, writing drivers and getting most of the changes upstream. None of the recent devices receiving a custom firmware had to go through that. If OpenDingux ever gets ported to the RS-97 it won't depend on the existing source code dump of the manufacturer. At most you could pull the LCD timings for one of the multitude of screens from the sources. Currently a KMS driver is being written to be able to move away from the age old framebuffer which isn't supported in newer generations of software and the Linux Kernel. After that you can expect userspace development to happen. Right now this isn't a priority.

If you want something with a CFW, then just get an RS-97 or LDK rather than the RS-90 because it is going to take a while.

Now I'm working on an installer/flasher, and at the end I will work on the UI.

Ah, that was my impression. I thought like missing was missing but no.
Pretty sure you are going to reuse Gmenu2x.

Btw, it comes to me right now that the kernel will only have a DRM/KMS interface available.
The RS-90 doesn't have a 3D GPU, which means no port of SDL2, the only one to directly support KMS.
And SDL 1.2 only supports fbdev, not DRM/KMS. (though it should still work if fbdev emulation is enabled)

So have you guys actually thought about that ? Are you just going to rely on fbdev emulation ?
I guess a basic SDL2 port to fbdev/framebuffer would be nice (as shown by the nxdk guys here (https://github.com/XboxDev/nxdk-sdl/commit/e53fc2da99e66f1a40b3262f26f850311fef0d2f)) because it might not be as optimal as one would liked

SDL2 does not require a GPU, it has a software renderer too.
SDL1 can just work on top of fbdev emulation, yes.

It does through DirectFB ? Because at least it doesn't seem to work over /dev/fbdev and i was under the impression that it didn't over KMS either.
I knew it had a software renderer, i'm just not sure it supports KMS with software rendering currently. But looks like i'm wrong ?

Hmm i guess a DRM video backend is something that could be looked at but it's probably not a priority. (i assume that you are still going to use SDL 1.2 for the UI ?)

I didn't do tests with SDL2 right now - maybe the software renderer doesn't work with KMS, but it would be strange, the video output and the renderer should be independent.

For SDL1, what's the interest in having a KMS driver? Using fbdev emulation will work just as good.

Well, as my Bittboy literally fell apart on me, this is now my go to take it with me handheld again. Here's hoping for something I can install on it sooner than later.
If you want something with a CFW, then just get an RS-97 or LDK rather than the RS-90 because it is going to take a while.
(They merged the DRM, ADC, Sound and LCD bits but they are still some other things missing.)

If you want to see what they did, see their commits here :
https://github.com/OpenDingux/linux/commits/jz-5.0-retromini (https://github.com/OpenDingux/linux/commits/jz-5.0-retromini)

Been there done that with the RS-97. I didn't care for the build quality on them either. I'm also kind of tired of waiting on Chinese shipping, so barring a cheap US seller, meh. Not really up for dropping 60+ on the LDK to risk another cheap PoS. I'm not short on things to play, I just don't have a good CFW handheld to take with me day to day. For now the RS-90 as-is, and my SP with an Everdrive will have to do.
Title: Re: Retromini RS-90 (JZ4725B) gba micro handheld
Post by: vermillion on March 18, 2019, 02:10:55 pm
I am also looking forward to CFW for the RS-90. I have the new Bittboy and it has some good points but the build quality is poor and it feels like it wont last long at all. The power switch and the usb port are particularly week areas and the device just feels cheap(which it is!). I Also have a RS-97 Which is much better than the bittboy but if you were only going to buy one device for emulation i don't think you could do any better than a ps Vita with cfw or a PSP go with cfw. I recently picked up a exploitable Vita  for 60 quid from my local game shop.
My RS-90 will wait patently until the great devs here are ready for a release. And my thanks goes to them for all there hard work.

The last update is fairly fresh:

Now I'm working on an installer/flasher, and at the end I will work on the UI.
So I'm guessing the first release is coming - which is great, as I still think this is the ultimate device for GB/GBC/GBA games, as long as it will run them using proper emulators.

Hey guys:

Want to make some updates to this excellent handheld we've seen, using, and waiting for a CFW release as i can see.
Perhaps this is already knew but, just want to share my experience in emulation with this beauty.

Overall:
I realized that some Zip files containing these emulator compilers, have different GBA emulators files to make the process (different sizes). Since there are a lot of 16bit chinese hanhelds out there, you cannot assume that everyone or version will perform perfectly so, for my RS-90 I did the tedious effort to check every single compiler and eureka, there was differences in performance. So for those who want to make some research or find the file, I can share the zip files without a problem. My main purpose is to put the RS-90 to the limits by testing every emulator that this thing could handle, waiting as you guys for a CFW, which i hope to be sooner. 

Emulation performance:














Is you guys want some info, please send me a message. I dont want to have this info by my own, obviously the purpose is to share for everyone, specially for those who put a lot of effort trying to look the capabilities of the Retromini GBA.

Bye.

@kokokool

I'd love to get PCE working on here. In fact Temper is like %90 of what I want out of this device. PCEAdvance was pretty much a non-starter for me though. It compiles and boots fine, but I didn't get to any games that were all that playable. Even on a GBA flash cart you usually have to tinker with the settings to get specific games running well. "Well" also assumes no sound and speed at 70%ish of full.

SMSAdvance I find runs well... slightly worse than Pocketnes, though that's the same on GBA flash carts too.

SNESadvance... Not worth the effort. You might get a couple of games to play tolerably without sound. (Gradius III, Super R-Type... maybe) For the most part though, SNES emulation never got very far on the GBA.


With 16 bit, you can muddle through a lot of SNES, and Genesis as long as you can handle the bad aspect ratio. No good way to do PCE at all from my experience so far. :(

There's no specific need, and certainly no reason to share links to illegal rom compilations. :) It's an issue of poor performance within the emulator. (PCEadvance in this case) In addition to that with no access to the in game emulation options, and the fact that it's an emulator running through an emulator. Most games are simply going to run poorly. You may have found a few that run well during testing, and I have no doubt that some might. Most PCE games however are going to fall in the "unplayable" category.

Post by: kokokool on April 20, 2019, 02:09:52 pm
Agree with you mate. But as i could see, some others are completely agree to test. I?m very aware about the impacts of share roms as an illegal procedure so yeah.

Anyways, the results shown above only tries to summarize something i couldn?t see at the very first months and suddenly I faced that some version of the emulator as well as some compilers have different console emulators, therefore, I could play games that with the other compiler nearly reached 10 fps, while the final compiler gave me 40-50 fps.

On the other hand, Personally SNeSadvance did not work pretty well. Too slow. Do you guys know other enulators that confirm playable emulation with image display fix? Native emulation at the time is the only way.

Finally, For what i try to achieve is to play the other platforms. 800xl and Mame ( any romset).

Hi guys. I've purchased two batches of 3 Retro Minis, about 8 months apart and they're fairly different from each other. This might only be an FYI sort of post but I am curious what layout others have received.

Both batches I purchased were bought on amazon. One was from a seller that kept their stock with amazon, so it was eligible for amazon prime. This batch came with 40 games in the built-in memory, and an 8GB micro sd card which had somewhere on the order of 500 games. Every single game in both of these memory spaces were all GBA games. I suspect this is pretty standard for what most people received because this is what I have seen advertised in most places, and the boxes this batch were received in had a barcode sticker on the side that said Coolbaby.

The second batch of three I bought from a different amazon seller as the original listing had been deleted and the seller no longer in the system. This listing said it would come with a 16GB micro sd card (I think) and more than 900 games total. The price cost approximately $5 less than the first listing at just $34.80. What I received was a Retro Mini that lacked any micro sd card at all, but may or may not have had a larger resident memory space, because rather than only 40 games built-in, it has 169. Also unlike the earlier batch, this game library is a selection of GBA, Gameboy Color, NES, SNES, Genesis, and Arcade even games, if you can believe it! The unit had its factory original language set to Chinese; after changing it, the file names in the game library remained in Chinese, as I rather expected them to for the most part, because if the filename is Chinese then the language setting is not going to change that, but the ROMs of many or most of these games were also Chinese or Japanese versions as well. The Punisher, Captain Commando, Street Fighter II Championship Edition and several other Capcom fighters were among the Arcade games included, all zipped up and everything. I know those are some oldies but I had no idea that this hardware was even capable of these games much less that an emulator for them had been written? Or is this another emulator-in-emulator (GBA emulator?) at work here?

I know that several people purchased a Retro Mini without a micro sd card but I have never heard of anyone getting a resident variety of games on their unit like this before. I don't have the technical know-how to dump this if it involves any hardware hacking, but I'm very willing to share whatever I can if this could be helpful to the effort for the Retro Mini. This is still my favourite hardware just because it feels so very right, even though it's tiny. The build quality is stellar and you can pound on it 24/7 without putting a dent in it, it would be great if the software is done up to the same standards as the hardware.

@kokokool thanks for your post about all the emulators.

But do the games play really 100% at 60fps full speed without any frameskipping?

I really can?t wait until the CFW is released for the RS-90.
It will be perfect for GBA and PC Engine (and Megadrive)

Forget Snes, that won?t be possible, but I don?t care.

Post by: kokokool on April 22, 2019, 08:10:17 pm
Im at the field right know with minimum of chance at this minute of share the emulators ( compilers and packs ive found that works for rs90 ) since being at heights ( 4000 masl) internet is  pretty slow. As soon as i get home ( perhaps these days) i?ll share the Dropbox link to share. I have two emails waiting so yeah, join to the request.

The only way to play snes 80% good, but with frameskipping is via native ( just as it is, placing the smc extension)

Now, something very interesting is that for Genesis, bin files worked pretty good very fluently.

I reach 55-60 fps in atari, Nes, msx games, gb, gbc, genesis and 85% games in gba ( Doom II is 10 fps). Snes i must admit that is a bit different, some games are fluid, some others not at all. But im doing bit research to get to the reason why snes are more difficult to manage, cus its not a hardware problem.

Something very interesting was the performance of MSX games converted to sms extension.

PC engine is a different thing. Yeah it does have frameskipping but i dont know, for me it works. we should share videos or create a whatsapp group to talk about videos and share content.

I understood in HyperionAlpha's post that his latest batch didn't come shipped with a micro SD card, but he meant that they don't have a micro SD slot? That shouldn't be a problem in practice, but if the rest of the hardware is different, I can't guarantee it'll work without some tweaking to the OS.

Clarification on my long-ass post: the Retrominis that I ordered most recently did NOT come with a micro sd card. Like every Retromini I have seen, it DOES have a micro sd card SLOT. The amazon listing simply stated that it would come with about a thousand games, and it didn't. The memory that is built in to the board holds the only games that these Retrominis come with from the factory, and it's a very, very different batch from my first one. My first batch had nothing but GBA games, in its built-in memory and in its 8GB micro sd card. This new batch has GBA, GB Color, GB, NES, SNES, Sega Master System, Sega Genesis, and even some Arcade games on it. Nothing I had read about anywhere prepared me for this, never heard anything at all about such a different set of ROMs being included.

Here is a link to the Retromini that I ordered, and yes it is an RS-90 Retromini, with the actual Retromini logo and all that -> https://www.amazon.com/gp/product/B07CHLFWPW/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

Clarification on my long-ass post: the Retrominis that I ordered most recently did NOT come with a micro sd card. Like every Retromini I have seen, it DOES have a micro sd card SLOT. The amazon listing simply stated that it would come with about a thousand games, and it didn't. The memory that is built in to the board holds the only games that these Retrominis come with from the factory, and it's a very, very different batch from my first one. My first batch had nothing but GBA games, in its built-in memory and in its 8GB micro sd card. This new batch has GBA, GB Color, GB, NES, SNES, Sega Master System, Sega Genesis, and even some Arcade games on it. Nothing I had read about anywhere prepared me for this, never heard anything at all about such a different set of ROMs being included.

Here is a link to the Retromini that I ordered, and yes it is an RS-90 Retromini, with the actual Retromini logo and all that -> https://www.amazon.com/gp/product/B07CHLFWPW/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1


Wait, one thing is to have a micro sd card slot and on the other hand, to include a x gb micro sd card.

Chinese websites manage products services in separate way and join them into a package for shipping.

When i ordered mine, it came effectively without sd card. I had to buy one locally and thats it. Dunno whats the problem here that im missing..

I don't care about getting an SD card with the device - I'm not that interested in the games that come with it.
I want the device so that I can add our own emulators on it and I like having an SD card slot to do this.

So thanks for you recent post @HyperionAlpha, who confirms that it does indeed come with the slot.
My previous post had an eBay link which has a three or so eBay vendors selling the Coolbaby Retro Mini RS-90.

I sent the same message to each seller - asking whether the device has an SD card slot and whether it comes with the card.

I've received two replies; one vendor said no SD card is included, the other vendor said no SD card slot. But I don't know if it's just a miscommunication. I've asked him to confirm/clarify his response.

Anyway, I'll probably order one as it looks like the CFW release is coming soon. Despite the screen size, I'd like to see how this device performs.

I'm hoping that the device's USB port will support networking? ie. ssh into it?

Why not just order a unit from China? They are half (https://www.aliexpress.com/item/Data-Frog-Retro-Game-Console-32-Bit-Portable-Mini-Handheld-Game-Players-Built-in-940-For/32906341231.html) the price (https://www.aliexpress.com/item/Retro-Mini-Handheld-Game-Player-32Bit-Portable-Classic-Game-Console-Built-in-36-games-For/32967847015.html) on aliexpress. Any unit comes with an SD card slot. If you want to know more about the current status of OpenDingux you can join the #gcw and #opendingux channels at Freenode via IRC.

I'm not sure how or when I said anything that made anyone think that the Retrominis I bought most recently, the actual, genuine Coolbaby Retrominis, did not have a micro SD card slot. I've seen them for sale plenty of places without a micro SD card, never, ever not once have I seen one for sale that didn't even have a slot. Likewise, every single genuine made-by-Coolbaby Retromini I have ever seen has only ever come with GBA games on it, whether on the resident memory in the board or in the micro SD card, if it came with one. Any time I have ever come across a variance of the games supplied, it's been through the micro SD card included, otherwise everybody just has the same 40 games.

I really honestly do not give a crap if it comes with a micro SD card or not, because if it does come with one it is only 8GB and that's tiny sauce by my book, I've already got 32GB cards that I will put in there without hesitation, I might even try a larger one in order to fit as many ROMs and even videos and stuff for my kids on the thing. The reason I made such a long-winded post in the first place about the batch of Retrominis that I last received is twofold: I got a Retromini with games that were not GBA games on it (Megadrive, SNES, NES, SMS, Arcade), and even some of what I would expect to be the more demanding games were running 100% fullspeed. Maybe that isn't a big deal to any of you guys but it was huge to me, made my eyeballs pop out. In this very thread I believe there are people complaining about frameskip that seems to be running in every GBA game, talk about emulating stuff other than GBA and everyone says "It's just too underpowered," it emulates other systems inside of a GBA emulator, etc. etc. etc. Well when I come across all of that and everything (except a couple SNES games) is running full speed, including an Arcade game emulator, I'm going to flip out. Does this mean different hardware? I doubt it, it's all Coolbaby Retromini. But they are writing this game batch directly to the board, not the micro SD card since they didn't include one. Did they rewrite firmware with better, faster code? Possibly.

Yes, i believe they re-wrote the firmware updating lots of things. Thats why CFW is critical because i sense that hardware is capable of support more than its original status.

Ohboy (https://boards.dingoonity.org/gcw-releases/ohboy/) for example will need to be ported to allow for GB/GBC support.

Linux instructions above for flashing copy the flasher to your desktop and type the commands then Hold Button A if not B then power on you will then get some commands like below.You then finish the rest of the install on the rs90 device itself enjoy :)

You need to go into device manager and find the JZ4725 device and right click - update driver. Then point the dialog box at the folder with pcerceui's drivers.

The drivers won't install if you don't have driver signature enforcement disabled:

SD cards support seems to be broken. Even if it appears in the filesystem the apps and emus will crash when trying to read from it. I'll add a workaround in the kernel, and update the flasher. In the meantime, avoid using external SD cards.

For the half-empty battery icon - it's just that the driver isn't very well calibrated.
