Title: Letcool Gamestation
Post by: Frank_fjs on May 18, 2010, 04:02:47 pm
Hi all,

Anyone have one of these?

http://dsdatabase.org/entry.php/176-Review-for-Letcool-handheld-console (http://dsdatabase.org/entry.php/176-Review-for-Letcool-handheld-console) <- Review + more info

http://www.taobaodao.com/goods-3342.html (http://www.taobaodao.com/goods-3342.html) <- site selling the thing

I'm a proud A320 owner and for the price can deal with its shortcomings. The A330 doesn't seem improved enough for the extra $$$ and it seems like most of the existing problems with the A320 will be present in the A330. No official, regular firmware updates. Not quite there yet emulation. Lack of 2 player support.

I don't know, I think the Dingoo manufacturers have created something wonderful, it's just a shame that they didn't back it up with more support and software updates. In my opinion the A320 is about 75% - 85% there, they just needed to go the extra mile to finish it off.

Anyhow, this Letcool device, on the surface, appears to be the answer - the Dingoo A320 as it should have been. What do you guys think?

I've been eyeing this also. If you do pull the trigger to get one, I'd love to see how it compares to the A320.

Some more info on this from another thread:

It definitely looks interesting, and I was also thinking of getting one.
(instead I bought an Eken M001 android pad ...)

I highly doubt that there will be firmware upgrades for this!
Also no SDK or open source OS. And it supports less emulators than the dingoo.
Nevertheless seems very interesting.

If you buy it, please review it here.

Are those hardware volume keys/sliders? The lack thereof is one of the things that nagged me about the Dingoo (especially with Dingux).
Title: Re: Letcool Gamestation
Post by: flatmush on May 18, 2010, 11:46:44 pm
Apparently it has a sunplus8000 chipset which does contain a 3d accelerator which would make this an awesome machine, however the lack of any kind of SDK or information kinda makes it useless since I doubt much chinese programming can make proper use of 3d accel.

Yep, ordered mine from Hopebuy -- awaiting them to get back to me for Paypal payment, but hopefully that'll happen soon!

It looks like a potentially good device. Found the review mentioned in the original post already, but that's about the only review out there for it. No screenshots/photos of the OS anywhere, but according to the sales packaging it'll be some PSP-style knock off, possibly like the native Dingoo OS.

I'm not expecting the device to be an open system, but if it's no good it'll be something to pass over to my nephews to play with once I'm done with a teardown/review!

I know I read somewhere that this does or can do 64bit emulation. Anyone else come across that?

Edit: Here it is  http://mp4nation.net/blog/2008/08/sunplus-8000-media-chip-tri-core-monster-with-hd-video-playback-support/

Not specifically about this handheld but the Sunplus 8000 chipset.

Great, please keep us posted.

To me, I would speculate that the makers of this thing saw the Dingoo scene, listened to feedback and made their own device based on a Dingoo but with improvements made according to what people were saying about their A320's. Two player support, shoulder buttons in the right place, camera is a bit of a wank feature but hey, why not, hardware volume buttons, wrist strap, micro SD, headphone jack on the bottom, replaceable battery etc.

The Dingoo team have created a nice market, they just didn't embrace it well enough (even with the A330 no-one really knows what's going on, are they released yet, are the ones available now fakes or inferior, who the hell is manufacturing them and are they the 'real' Dingoo company or a bootleg company - it does my head in, God who knows.

I really hope the software doesn't let it down, I am really liking the look of it. Pity about the lack of arcade emulators but you never know, that may change... Eagerly awaiting your review omgmog. :)

Really cool. A Review like you did for the a330 would be great. Please open it and make some pictures. Also a backup of the included Apps + OS (firmware) would be nice.

Looks interesting. With the extra control pads and TV-out it would be nice if SNES, Genesis emulation is much better than the Dingoo native emulators

If something like Dingux can be installed on this thing I'll most definitely buy one for those 92 dollars! (which is not even a fist full)  :P

P.S. The reviewer from the link in the top post says the Letcool has "a vibrant development scene ? thanks to its open source nature". How's that possible if no-one has it yet? Is this vaporware people?
Title: Re: Letcool Gamestation
Post by: mortys on May 19, 2010, 02:39:23 pm
As said Science, it could be cool is to upload the file app and maybe  try to launch a dingoo ap on it (I'm always dreaming that chinese game station use the same kind of firmware).

Would it be possible for the community to build a homebrew SDK for the Sunplus 8000? I think given enough time and community buildup, pretty much anything's possible. I remember the Dingoo homebrew community started out really slowly, and then DINGUX was born, which kicked homebrew development into overgear.

Some more info on the Sunplus 8000:
http://mp4nation.net/blog/2008/08/sunplus-8000-media-chip-tri-core-monster-with-hd-video-playback-support/

The mp4nation community is starting to pick and probe the Sunplus8000:

Oh my, this handheld looks very big in comparsion with a A330.

But ok, as far as i know it has an 3,5" 800x480 display.

Do you have also the letcool (eg did you make the picture?)

If yes could you write a small review about the letcool.
Seems to be really an interesting device, but I fear that the SW is extremely buggy, and that there is no public info/SDK available.

thanx in advance

-e- oops, the forum doesn?t scale images?
Interesting device, but i don?t think it has a 800x480 screen, as that would be widescreen (WVGA). I?d like 640x480, but that?s a bit unlikely i guess.  :D
I wonder what the battery life is like, the chip is huge, and the supposed 1050mah battery tiny!

Post by: joanilson41 on May 20, 2010, 01:06:01 pm
well, it's look really good, with this joysticks it become interesting....
the "consoles" with Sunplus 8000 are called spmp8000, because there are almost the same thing, just change the design and menu pictures...
i have a JXD V3, and i say that Sunplus 8000 is a great hardware, but there's bad firmwares and no development tools, the emulators are not bad, but the button mapping turn some games unplayable...

AleMaxx is the guy in MP4Nation that did the working Doom version, with no sound and no ingame options yet, but working with really nice graphics! there are some ppl interested in doing anything, but few experienced programmers in SPMP8000 scene, that's why it's not great by now, but if more hackers and programmers buy these pmp's, so we can have more stuff...

That think just looks too much like a DS (Maybe it's because it was Designed in Japan?)
I would also like to hear how it is from the people that is getting this. WE DEPENDZ ON YOUR REVIEWS!!!! NO LET US DOWN!!!!!!!
Mostly I want to know about the Video Resolution. The Dingoo has the resolution of 320X240 and any video that has the resolution over 320x240 will most likey lag in the video, and also the Dingoo will push the video Resolution down into 320x240 even though the Video actual size is [let's just say is 640x480]
Aside from Video [I know the MP3 is good and the Voice recording and Radio Sucks] I [And all my peers] want to know if the Emulators are good. This is the big one everybody wants to know but no info on.

MAKE THE YOUTUBE VIDEO OF THESE PLEASE!

Thank you drive thru....

Bit OT but in my experience as long as bitrate isnt too high (above 900kbps or so) and vid resolution isnt larger than around 700 pixels wide video plays fine on the A320. This with xvid encoded video

Gonna try that thanks!
Anways, the controller seems to be a little too small for me. It's a super Nintendo controller but the D-pad and Buttons pushed the Start and Select buttons up. And I hope the wire is more than 3 feet. Cannot sit that damn close to a tv even with a little help from the AV-cable it still wouldn't help.

 Got a message from Goldenbridge.hk about a day and 1/2 after ordering that they were out of stock on black(which i ordered). They said they had white if I wanted to swap. Of course I did.So my order was delayed by a couple of days due to exchange of emails. Marked as shipped on saturday.Used UPS so will have in 3-5 days.

Yeah, I'd say its fixable - the L/R buttons don't adjust volume in the menus whereas the +/- buttons do, so its not a case of L/R just being hardwired to +/-.

They emailed me saying:

Dear Max Glenister,
 
The DHL changed your shipment with another air waybill, and the new tracking number is <snip>.
Wish you would receive them soon.
If you have any questions, please feel free to contact me.

Best Regards.
Sales Department
www.Hopebuy.com

so I went to the DHL website and put the number in, the number checks out and the parcel is at my local DHL delivery place.

It was kinda odd that this was the first that I had heard of my tracking number, but the number I got works so I'm not complaining there.

You might find problems with DHL from/to some countries because DHL have been bought out by HDN (source (http://www.hdnl.co.uk/Press-Room/Latest-News/HDN-Announces-Acquisition-of-DHLs-Domestic-B2B-and-B2C-Parcel-Delivery-Business/))

 My Letcool has arrived. Heres a pic of it next to my (now dead) dingoo.

(http://i882.photobucket.com/albums/ac28/1wiierdguy/th_IMG_0586.jpg) (http://s882.photobucket.com/albums/ac28/1wiierdguy/?action=view&current=IMG_0586.jpg)

 First impressions of the unit itself are good. The letcool is light but feels very sturdy and well built.  The larger size means it fits better in the hands with my fingers resting comfortably on the shoulder triggers. The shoulder triggers are clicky like the dingoos but the start/select and volume buttons are not. The main face buttons are very nice with a similar feel to the A320, they are a bit bigger though. The dpad looks bigger but a quick check with the ruler reveals it to be the same size. It feels a bit stiffer than the A320s but it could be just newer.
 The mini control pads feel very nice with a very solid d-pad that is deeply concaved in the middle holding the thunb very nicely.The face buttons are quite clicky and the shoulder buttons are soft rubber not hard plastic.
 All in all I'm very happy with the build of the unit itself. Will go now and test it and will update my findings later.

Looks about the same size as the DSi then, awesome.

Please test :-)
-Resolution of the LCD?
-What's the TVOut resolution?
-How does the TVout work (menu, emu, movie)?
-Does it play DIVX/XVID avi?
-What's the max bandwidth (700~800kb/s)?
-What's the max. resolution of videos. 720p?

And please test some special roms with the SFC/Snes emulator.
-like Secret of Mana (highres rom)
-StarFox
-Dungeon Master
-aso.

How does the Emulators feel in comparsion to Dingoo?

thx.much.
Title: Re: Letcool Gamestation
Post by: 1wiierdguy on June 01, 2010, 11:23:14 am
 O.k. the small amount of charge it came with has run out. Have put it on charge so I'll post about it a bit more.

(http://i882.photobucket.com/albums/ac28/1wiierdguy/th_IMG_0589.jpg) (http://s882.photobucket.com/albums/ac28/1wiierdguy/?action=view&current=IMG_0589.jpg)

 The wall charging unit it comes with is exactly the same as the dingoo. Like the dingoo it can not be off while charging automatically coming on when plugged in. I did notice that unlike the Dingoo the battery is removable and easily replaceable.
 Unfortunatly the system is a mixed bag from my tests so far. Some of you may have read on other forums that when playing on the system controls(no mini pads) that the shoulder buttons do NOT act as L or R, unfortunatley I can confirm this is true. They operate as volume up and down with no button mapping available. Therefore for GBA the shoulder buttons are mapped to X and Y and for Snes there are NO shoulder buttons on the system.When pugging in the mini pads this is corrected for Snes but NOT for Gba with the buttons still being mapped to X and Y.And you would think with X bieng on the right side it would be mapped as R. It is NOT. Y is mapped to R.
 The screen on the unit is nice but there are NO options to change brightness. The level you are stuck on is not as bright as the Dingoo screen set to 3. I think the screen does not look as sharp as the Dingoos probably the same res stretched over a larger size.My unit also has 1 stuck pixel in the top right corner.
 For the Emus themselves, of what I've tested so far:

 NES - Very nice as you would expect detected a little slowdown in some games that the Dingoo does not have.
 GB - Again very nice SMB Deluxe doesn't work like on Dingoo Native but others I tested ran  perfectly.
 GBA - A big step down from dingoo. Games are very choppy and with the button mapping issue. Not Good.
 Snes - NOT playable without mini pads. Game performance is hit and miss. Less sound issues than Dingoo native but feels slower.
 MD - A definate step up from Dingoo native, games ran much smoother and with less sound issues.

 Initial findings are that two player MD is this units early strength. With any luck a firmware upgrade can fix some of the other issues. The manual gives instructions on how to do firmware upgrades so hopefully one will be released soon.
 
 Not tested T.V. out yet, or movie playback. Will soon. The operating system is very similar in function to Dingoo as you can see in new pic.
Title: Re: Letcool Gamestation
Post by: Frank_fjs on June 01, 2010, 11:36:43 am
Yeah, the OS does look strikingly similar to the Dingoo. Not that that's a bad thing.

From what you described build quality sounds good which is important, I like that the battery is readily replaceable.

I guess what's going to make or break this little unit is the firmware. If it is updated on a regular basis & the minor issues are ironed out then this seems to be a wonderful system with a great potential. Additionally, hopefully the firmware can be hacked (or it is made open sourced as is advertised) then there would be no stopping this thing, imagine all the emulators you could add & how cool they would be with 2 player support.

Heck, even with the shortcomings you described it still seems like a kick ass unit even if for just playing nes and mega drive games two player - plus all the other stuff (mp3, videos, camera etc).

I also got my letcool, here are my first impressions. The corners of the case are also a bit sharp - this could be solved by using some silicone covers. The controls are nice if a bit clicky. One problem I've had is it only allows you to use the flash memory OR the TF card, not both at the same time. You have to manually go in and change the system settings.

Please test :-)
-Resolution of the LCD?
-What's the TVOut resolution?
-How does the TVout work (menu, emu, movie)?
-Does it play DIVX/XVID avi?
-What's the max bandwidth (700~800kb/s)?
-What's the max. resolution of videos. 720p?

And please test some special roms with the SFC/Snes emulator.
-like Secret of Mana (highres rom)
-StarFox
-Dungeon Master
-aso.

How does the Emulators feel in comparsion to Dingoo?

thx.much.


Can't find resolution of the screen.
Tv shows as receiving Pal or Ntsc signal depending on what is selected. So output is 480 or 576.
Tv out looked nice, didn't use Tv out on Dingoo so cant give comparison.
Yeah tested some avis and they played. Manual gives Rmvb, dat, Rm , Mpeg1+2+3, flv, H263, Wmv Avi, Asf 3Gp and Vob as supported playback.
Not sure about bandwidth or max Res. Manual says it plays HD but  gives no max resolution.

 Tested Secret of mana, plays nicely with no text issues and decent sound.
 Starfox will not run.
Don't have Dungeon master to test.

 A couple of other things. The screen definatley has a sweet spot tilting the unit forward or back changes the clarity of the image. Not being as bright as Dingoo might not be Ideal for games but for movie playback it gives a very nice and natural looking picture. Add the bigger screen and I prefer this unit for movie playback. Oh and when charging through AC screen will NOT turn off regardless of setting. Charging through usb and it turns off in time with setting. Will be doing usb charging to save screen.

*Edit- One moe thing the MD is always 3 button even when using pad. NO six button setting.

Whats installed on the system? Can you copy and ZIP the internal flash memory and give a link (megaupload or something)?

that's a strange word to have printed on the console front.

well i was all set to buy the a320 but that nice larger screen is just what i want so now i gotta wait to see if and how well mame  runs on this letcool thingy so it's back to the waiting game for me.


rumours are if you put a letcool near to an a330 console a little hammer extends from the letcool and smashes the a330 to pieces

The topic is locked to discussion, but you can talk about it in this thread.

Currently in the process of dumping the Letcool nand. As it's a SPMP8K device, there are already tools around to dump the nand, and as you will read in my posts, there exists software that is compatible with it.

Boot process uses Redboot, and the OS on the device is eCos

Awesome, thanks. Lower pixel density = we can now emulate handheld consoles at native resolution without having to scale. Yippeee! We lose some sharpness, but I'll trade that for not having to squint when playing games without using a scaler any day.

omgomg, when you dump your firmware, can you upload this?
i have a jxd v3, and i'm on mp4nation thread, in jxd v3, the emulators are out of the firmware folder, so i can change this without flashing the device! but the results of the emulators of another spmp8000's are crash or same/lower performance...

the button mapping is a big problem on spmp8000, on v3, the C button of genesis is mapped on Power, so, when you press, it pauses the game, enter in the option menu, what make a lot of games unplayable, but the Mega Drive (Genesis) emulator have a very good speed, good graphics, but without c, it only worth to play Sonic games. In the SNES, the button mapping is even worst, there's no X mapped, L & R mapped as square and triangle, Y mapped as both volume buttons...

well, if you can edit the 8000_mmi.rap (the main OS file), we can fix it, to all spmp8000 devices.

I hope the letcool owners could improve de spmp8000 scene!

The Letcool and all of these other SPMP8000 systems all boot with Redboot, and run eCos, so I don't think it would be too much of a stretch to get a Linux kernel booting on there, or even get Nano-X running on eCos.

Man, things are starting to get exciting for this Letcool.  I hope it gets as big a following as the Dingoo.  It seems like it deserves it. 

BTW, I read about the Sunchip that's in the Letcool and apparently it even has a 3D graphic engine within it.  I kinda doubt the Letcool uses it now, but would it be possible in the future to access this?  Or does the Doom port already use it?

Yeeeehar! But that would mean that all Dingux's emulators would have to be recompiled (LetCool has a different CPU, is it not?). Doesn't that require a so-called "toolchain"? Is that easy to make? Well, I'll wait and see.... :)

The menu's use 3D effects for transitions, so it's entirely possible that it's utilising the 3D stuff.

Hello boys, I'm new to the forum :-). I don't own a Letcool device but an ugly looking psp clone which has similar hardware (i.e. it uses the sunplus spmp8000 soc). So to my knowledge its an arm9 with ceva x1620/mm2000 dsp plus the usual soc peripherials (some of them seem to be based on std. arm "primecell" hadware) and there are rumors about 3d hardware acceleration.

About the 3d, I investigated the firmware a little bit and Im pretty sure it doesnt use hardware 3d. The 3d-transitions are software based. I read somewhere that sunplus has licensed the MBX core though but the last time I read the MBX wikipedia article the sunplus chip that uses this was still unidentified.

Btw, are some of you guys interested in doing some letcool/spmp8000 hacking? So far its possible to write .bin games and if you soldered some wires to the boards/chips uart pads/pins you can even run code from the redboot console (for uart related stuff have a look at www.openschemes.com).

O.k. the small amount of charge it came with has run out. Have put it on charge so I'll post about it a bit more.

(http://i882.photobucket.com/albums/ac28/1wiierdguy/th_IMG_0589.jpg) (http://s882.photobucket.com/albums/ac28/1wiierdguy/?action=view&current=IMG_0589.jpg)

 The wall charging unit it comes with is exactly the same as the dingoo. Like the dingoo it can not be off while charging automatically coming on when plugged in. I did notice that unlike the Dingoo the battery is removable and easily replaceable.
 Unfortunatly the system is a mixed bag from my tests so far. Some of you may have read on other forums that when playing on the system controls(no mini pads) that the shoulder buttons do NOT act as L or R, unfortunatley I can confirm this is true. They operate as volume up and down with no button mapping available. Therefore for GBA the shoulder buttons are mapped to X and Y and for Snes there are NO shoulder buttons on the system.When pugging in the mini pads this is corrected for Snes but NOT for Gba with the buttons still being mapped to X and Y.And you would think with X bieng on the right side it would be mapped as R. It is NOT. Y is mapped to R.
 The screen on the unit is nice but there are NO options to change brightness. The level you are stuck on is not as bright as the Dingoo screen set to 3. I think the screen does not look as sharp as the Dingoos probably the same res stretched over a larger size.My unit also has 1 stuck pixel in the top right corner.
 For the Emus themselves, of what I've tested so far:

 NES - Very nice as you would expect detected a little slowdown in some games that the Dingoo does not have.
 GB - Again very nice SMB Deluxe doesn't work like on Dingoo Native but others I tested ran  perfectly.
 GBA - A big step down from dingoo. Games are very choppy and with the button mapping issue. Not Good.
 Snes - NOT playable without mini pads. Game performance is hit and miss. Less sound issues than Dingoo native but feels slower.
 MD - A definate step up from Dingoo native, games ran much smoother and with less sound issues.

 Initial findings are that two player MD is this units early strength. With any luck a firmware upgrade can fix some of the other issues. The manual gives instructions on how to do firmware upgrades so hopefully one will be released soon.
 
 Not tested T.V. out yet, or movie playback. Will soon. The operating system is very similar in function to Dingoo as you can see in new pic.
Thanks for info,GBA suck aye... not good

That sounds pretty cool.  That's probably the main selling point for me, the 2-player controllers.  It would be so easy to leave the A/V cables hooked up to my TV, and then when I have friends over or want to play old-school games with my kids, just plug in the Letcool + controllers and game away.  I do hope they release an update for that pesky L/R button problem, though.

And this is probably a stupid question, but does the camera only take pics?  Or can you record video with it, too?

I'm no assembly/processor/C expert. By no means at all. However, I build applications from (C++) source code sometimes too on my Linux computer. And this error message:
Code: [Select]
Error: selected processor does not support `mvfeqd f0,#0.0'seems to tell us that the assembler, which is trying to build the GNU C Compiler (gcc), is having trouble w/ building some sort of code (or some sort functionality) because it can not be executed on an ARM-Elf processor. Or did you know that already and did I explain soething very, very trivial to you? Sorry, just trying to help (I can't find anything helpful either on Google).

Maybe they can help you on a good Linux/Compiling/Hardware forum... I most certainly hope so, because I already like the LetCool from all I've seen so far! Keep up the good work Omgmog! And good luck. :)

I've been googling around too, running "make all" again now with some options uncommented in the gcc configs (gcc/config/arm/t-arm-elf) which might help according to a post on the gcc mailing list...

Okay it turns out it was failing because I was using a newer version of GCC. Changed over to GCC 4.3.3 and "make all" worked fine! Onwards with setting up the toolchain! (http://alemaxx.al.funpic.de/spmp8000/sp8hc.html)

Okay it looks like I've got my toolchain set up correctly.

I get an error about ../libgame/start.o not existing when I run 'make' in the libspmp8k-read-only directory, but the rgbgame.bin builds and packages as .bin correctly -- the .bin works fine on the Letcool too :D

Time for some sleep now, but I will be playing with this some more tomorrow

The missing start.o problem is fixed easily by editing demos/libgame/Makefile, change this:
Code: [Select]
all : $(OBJS)
$(AR) $(ARFLAGS) $(TARGET) $(OBJS)
to
Code: [Select]
all : $(OBJS) $(START_O)
$(AR) $(ARFLAGS) $(TARGET) $(OBJS)
and re-make it. Some people reported that they had problems with the svn version such that images don't show. I will check this.

@1wiierdguy

That sounds pretty cool.  That's probably the main selling point for me, the 2-player controllers.  It would be so easy to leave the A/V cables hooked up to my TV, and then when I have friends over or want to play old-school games with my kids, just plug in the Letcool + controllers and game away.  I do hope they release an update for that pesky L/R button problem, though.

And this is probably a stupid question, but does the camera only take pics?  Or can you record video with it, too?

The camera shoots stndard def video with audio.

Why don't create a wiki, or a souceforge/googlecode project for people that wants to start programming for this lovely new console?

The look, the size, the number of buttons, the hardware are pretty good.

This console should be the REAL candidate for Dingoo successor.

Also a donation for buying the console for someone like Booboo for investigating and hacking purposes should be good.

Keep up the good work guys.

Things looking great! I've just updated some pages in the wiki.

Did you try dumping your firmware using the FRMorp yet? If you do, would you mind to upload it somewhere so that everyone can download it? I want to investigate a bit of Letcool firmware, whether it is an updated firmware or just the same like any other previous spmp8000 devices. Among thing I want to find is about the flash player since they included link to download many flash game in the main Letcool site. But I try to play in my spmp8000 it just turn out blank. Performance issues I guess since many other flash file I've tried before are very laggy.

Hi jiraiya78, I would say that the firmware (the 8000MMI.RAP) is different, since the letcool has a different screen and most probably another button layout. The emulators are replaceable I think although I haven't tried it yet. They look much like bin games but without the header and they use a different API (but not very different). The flash player is build into the main firmware iirc.

Inside the SOFT.IMG the emulators are just bin files as I'm sure you're aware, and yes there is a "flashlite.bin" in there too
Title: Re: Letcool Gamestation
Post by: alemaxx on June 09, 2010, 12:18:25 pm
Indeed, there is a flashlite.bin and even a swfplayer.bin, my fault. This is a list of the files in "IMAGE/GAME" from my firmware:
Code: [Select]
1560916 2010-02-06 13:22 FLASHLITE.BIN
   74324 2010-02-06 13:22 G1.BIN
   22963 2010-02-06 13:22 GAME_CONFIG.TXT
   16384 2010-02-06 13:22 GBA_BIOS.BIN
  776132 2010-02-06 13:22 GPSP.BIN

   70076 2010-02-06 13:22 N1.BIN
  343156 2010-02-06 13:22 S1.BIN
   61492 2010-02-06 13:22 SWFPLAYER.BIN
  130500 2010-02-06 13:22 TONELIB.BIN
I included the filesize for reference, maybe the Letcool has later versions.
Btw, this is how the emu API looks like:
Code: [Select]
.data:004B0E0C                 DCD emuIfGraphInit
.data:004B0E10                 DCD emuIfGraphShow
.data:004B0E14                 DCD emuIfGraphChgView
.data:004B0E18                 DCD emuIfGraphCleanup
.data:004B0E1C                 DCD emuIfSoundInit
.data:004B0E20                 DCD emuIfSoundPlay
.data:004B0E24                 DCD emuIfSoundCleanup
.data:004B0E28                 DCD emuIfKeyInit
.data:004B0E2C                 DCD emuIfKeyGetInput
.data:004B0E30                 DCD emuIfKeyCleanup
.data:004B0E34                 DCD emuIfGetCurTime
.data:004B0E38                 DCD emuIfTimeDelay
.data:004B0E3C                 DCD emuIfFsFileOpen
.data:004B0E40                 DCD emuIfFsFileGetSize
.data:004B0E44                 DCD emuIfFsFileWrite
.data:004B0E48                 DCD emuIfFsFileRead
.data:004B0E4C                 DCD emuIfFsFileGetChar
.data:004B0E50                 DCD emuIfFsFileSeek
.data:004B0E54                 DCD emuIfFsFileCurPos
.data:004B0E58                 DCD emuIfFsFileClose
.data:004B0E5C                 DCD diag_printf
So its quite a bit different from the game API (which can be found in SK8015A.DAT @.text:002B85C0 initFunTable).

Yeah, I figure it would be like that because before I tried bmorn666 firmware. It shows blank screen when boot using their 8000MMI.RAP but i switch to my own 8000MMI.RAP then it's works. Maybe because in 8000MMI.RAP contain the hardware information such as the LCD controller, I don't know.

Yep, I also want to try the emulator and I have tried before, they are replaceable using sUNpack replace file function. I expect nothing different though (I have the impression that those chinese electronics company really lazy updating their firmware).

The bin files for the apps should be fine on any spmp8000 device -- games for other devices work just fine on the Letcool.

Inside the SOFT.IMG the emulators are just bin files as I'm sure you're aware, and yes there is a "flashlite.bin" in there too

Flashlite.bin is what interest me whether they update it but like I've said above, I expect them to be the very same revision.

I think there are also another file that concern me, sound like flash file too. It called "swfplayer.bin". It should be also in the "flashlite.bin" folder.

There's a load of audio/video/image codec *.bin files in the SOFT.IMG too, these will probably work on other machines too to open up/allow more formats if they're not currently available
Title: Re: Letcool Gamestation
Post by: joanilson41 on June 09, 2010, 01:00:00 pm
the most of spmp8000 firmwares are very similar, the one i saw that's a little different is the jxd v3, because the emulators are not in the firmware, they're in the folder of games, in a sub-folder called player.

8000_mmi.rap is the main file of the OS, there's all information about screen, keys, and a lot of stuff, so this file is different for each device, but the emulators, codecs and all the other things (except the theme) are the same or almost the same. i've changed my emulators, but with no good results, if the result was not the same, was worst or blank screen, but nothing changed about keymapping.

the jxd v3 emulators are strange, there's 2 files from each emulator, not just one, like in the other devices, but the 2 files have the same size, it's weird to me...

ps: i have downloaded more than 10 firmwares from different spmp8000 devices!

It could be. But if no possible way of repacking firmware back to .IMG, we still couldn't add any files. I try using FRM 1.1 to repack folder into IMG file but the advance tab is blank. I think at openschemes they said it possible. And there are even screenshot. Not sure what's wrong.

I doubt that they are compatible although I haven't tried it. The header is pretty much the same but for the SPMP8000 the 1st k of code is encrypted using 3DES and games (as well as the emulators) are loaded to 0xa00000 instead of 0x24C00000. So if you don't compile it with -fPIC it most probably wont work. Furthermore he uses a jumptable located at 0x2400c00 while the SPMP8000 bin games use a function table thats passed in r0.
Btw, the .bin codecs contain cx162x dsp code and there is no compiler available yet. Actually these are MMI files, like the 8000MMI.RAP and I think also the Redboot.img (there are some tools in the svn that calculate checksums for these files and thus allow to patch them).

Ok for starter, I see that many of the files is just exactly the same including the codec, of course taking out the picture and MMI files. I noticed also this firmware uses truetype fonts, like Bmorn666 firmware. The usage of the truetype font is in the MMI files so I can't do much about this, unless the MMI files is compatible with mine. Using truetype is much more anesthetically beautiful so it's interest me.

The emulator is just the same old thing. But there are two new files in the "GAME" folder, which is "G2.bin" and "G2_BIOS.bin". I highly suspect that this is just the same gPSP since the file size is just about the same, maybe some tweak/configuration to match letcool button. That also mean the letcool have different button mapped for gba, and should have same performance issues. And also they still use the same gPSP version. I wonder what old gPSP did they used, maybe the last known source leave by exophase. Oh, and GAME_CONFIG.txt of the gPSP is still the same.

I will try this firmware on my spmp8000 whether it will works or not later. Well, I don't expect it to works though.

On that note, I got the pong.bin for the spmp30xx to compile using your libgame stuff, after I replaced the game.ld, makefile, removed references to sound stuff, etc.

I understand similar portable handhelds can be modified to run Linux, can the Letcool N350JP run Linux?

Maybe. If you are a hobbyist and are interested in porting Linux and other software or emulators to the Letcool N350JP, then please contact us! We would be happy to provide you with support!!

[...] it made a nice pong.bin, but had the same problem that it wouldn't run :(
But I guess it doesn't say "unsupported file type" but only appears to do nothing? I had a short look at the pong source, the "sp_pic_decl"(pong) and "gfx_loadimg"(libgame) structs differ (API seems to be incompatible too) so one also has to rebuild the pic.c which would be as simple as adding all the png names into the Makefile if png2c wasn't limited to 4bpp png images. Anyway, I like to hear that somebody tried out the libgame (I think you are the first omgomg). Great :) If you have any questions I will surely answer them.

Well, I made a first attempt to start a linux port for the spmp8000 a while back but it bails out somewhere in "start_kernel()" (init/main.c).
Okay, since it seems that there are at least a few people interested in this, I uploaded the linux code I have and the quake source here:
http://alemaxx.al.funpic.de/spmp8000 (http://alemaxx.al.funpic.de/spmp8000/)
Read the "README" in the sp8lin.tar.bz2. The quake code may not work since I am using a slightly modified libgame but I uploaded the glue.c too (maybe it helps). I will update the svn but currently I dont have my device available to test that everything is working.

Initially I had the "unsupported file type" message, then it progressed to black screen/lock up :P

I assumed it might be generally down to my lacking C knowledge, but anyway yeah I'll have a play around some more.. and probably start from something a bit more simple :D

Thanks for uploading your work so far, it'll be useful with the help of some more eyes I expect :D

I imagine the best place to get Linux going would be with Redboot.

I've just taken a bunch of photos of the Letcool guts, and I'll amend my other topic with these photos shortly. Should be able to ascertain some idea about what hardware we've got from those.

If we can get a jtag connection on the board, I imagine it'll be useful to know what's going on.

I only thought this would be strange since mkbing prepends a header and the firmware checks this header and says "invalid file" if the header isn't there or contains values it doesn't expect.

Its definitely recommended to use the Redboot console via serial to test the kernel. The Redboot version installed on the device doesn't support booting a linux kernel, thats why the lxboot.S is there (kinda "nano bootloader").

Nice photos, I always fail at taking good photos of such things. Btw, I also made some while back:
http://i43.tinypic.com/2jfwsjl.jpg
http://i43.tinypic.com/2yl4jg3.jpg
(I didnt include the pictures directly since thy are a little to large, does the "img" tag offer scaling options?)
Some comments on your pictures:
pic3) TP1 TP2 (lower right of the chip) are the uart/serial pins. You can solder some cables here and another to some GND pad to connect it to you pc via serial port. To decide which one is RX/TX check this out: http://www.openschemes.com/modules/wordpress/2010/02/04/spmp8k-serial-port-pinout. The SPMP8000 has 3.3v logic levels so you would need a level shifter (MAX232) or an FT323 like for example this one: http://www.sparkfun.com/commerce/product_info.php?products_id=718 or you can modify a USB cellphone cable.
You mention somewhere that you suspect the chip to run at 200MHz, the bootlog says:
Code: [Select]
ref_clk: 243000000 Hz
sys_clk: 121500000, sys_ahb=60750000, sys_apb=30375000 Hz
ceva_clk: 243000000, ceva_ahb=121500000, ceva_apb=60750000 Hz
arm_clk: 243000000, arm_ahb=121500000, arm_apb=15187500 Hz
So it seems to run a little faster at 243MHz. (taken from: http://www.openschemes.com/modules/wordpress/2010/01/14/full-bootup-text-of-spmp8000/2/)

2. The manufacturer seems to be another company called Pantherlord (http://www.pantherlord.net.cn/athena/offerdetail/sale/pantherlord-181322-659641928.html). The product is called 'NDS GO' by Pantherlord  ;)
3. It's using standard Nokia BL-5B mobile phone battery.
4. The CPU is so called Sunplus PGP-200. Could be a variant of PMP8000.

Ours is the factory-direct version running on the Sunplus PGP-200 processor and designed by Nokubuni Tsuibo at 100Per Studio Designers in Japan. Others are probably just knock-offs sold by questionable suppliers.

Chinavision have spelled the name wrong anyway, it's "Nobukuni Tsuboi" which I believe might be "坪井信邦", I think his influence might only be because of the rubbery grip applied to the console + controllers. Design-wise it's mimicking a DSi, which isn't anything spectacular.

Does that really matter all that much, though?  I mean the PSP is clocked at 222MHz by default.  I do believe they released a firmware update that raised it to the rated 333MHz of the chip.  Besides, many have criticised even using Hz to rate a CPU's speed/performance, since it isn't merely clock speed that determines those things.

Ok, I make processors as a research student so I know what I'm talking about.

MHz does count in this case since the instruction sets are very similar and there isn't other hardware to consider, these are very simple chipsets with a CPI close to one, a MHz for MHz comparison is pretty fair, I don't think arms conditional execution or inline shifting is going to make up for it's half clockrate.
The PSP can't be compared like this because it has two cores, a graphics engine, different speeds of RAM, etc. Sunplus and jz4740 are both fairly similar single core SOC's.

MHz isn't a viable comparison for many architectures now since all instruction sets have different instruction densities, architectures execute different numbers of instructions per cycle, etc. The reason these cores can be compared MHz for MHz is that they are both single-issue in-order cores with simple fairly similar RISC instruction sets, cache architectures, etc.

Didn't realize the chips were so similar in architecture.  Then again, I'm not going to claim I have a huge knowledge in CPU's.  Guess I should have just kept my big mouth shut.  :P  So you don't think the internal graphics engine and DPS will make that much of a difference?  That's kinda disappointing.

I agree with flatmush, both chips are very similar ARM/MIPS but the jz is running about 44% faster. On the other hand when it comes to decoding videos the DSP should make a (not so small) difference and it can of course be utilized for other tasks (http://www.tesbv.com/index.php?option=com_content&task=view&id=42&Itemid=94) but as long as there is no ceva-x compiler available its useless. I probably should mention that we are not left without any hints to the ceva-x instruction set, these files:
http://www.lauterbach.com/cgi-bin/update.pl?file=_icdcevax_win.zip
http://www.lauterbach.com/cgi-bin/update.pl?file=_icdarm_linux.tar.gz

I think there is some misinformation there.. Booboo has been MIA since last November.

Why would a dingoo/gemei/chinachip (read: mips) based developer move over to ARM?

The topic is about the equally awesome Letcool N200 -- a "home console" style Letcool, which I suppose might have the same hardware as the N350JP, just without a screen or controls on the unit. Looks like it has USB-host, or atleast is using USB connections for the controllers which is an awesome thing.

We were talking about it a little last night. Zear said he wants to play DOOM split screen on it, that's all :P

OH you're correct -- that's an oversight on my part

The K4H561638H-UCB3 is the 256Megabit (32MegaByte) chip, and the second K9LBG08U0M-PCB0 chip is actually the NAND.

So, that would be 64MB total.  Same as the A330.  I do have a question though, omgmog.  In the guts description you say that both RAM chips are Samsung K4H561638H-UCB3 chips, but how come the second chip has different markings?

OH you're correct -- that's an oversight on my part

The K4H561638H-UCB3 is the 256Megabit (32MegaByte) chip, and the second K9LBG08U0M-PCB0 chip is actually the NAND.

Sharp eyes there  ;D -- I will update my post!

lol, no problem, man.  Was going to say something about that earlier, but it slipped my mind.  Only bad thing is with that one post, we are now back down to 32MB of RAM.   :P

BTW, any estimation on when the full review will be done?  Or is it a WID situation?  Also, are you planning on anymore vids?  I would love to see a preview of some of the games in action.

Is there anything to back that there is no 3-D accelerator?
To my knowledge there is no hard evidence but the firmware doesn't seem to use it (also no references in the code) and the datasheet of the SPMP8016a (http://alemaxx.al.funpic.de/spmp8000/SPMP8016A_ds.pdf) which otherwise looks very similar to the SPMP8000 doesn't mention it. Sunplus seems to have licensed the MBX (http://www.imgtec.com/partners/Sunplus.asp) though.

I'm kind of just reviewing/noting things as I go along. Couldn't do a good review of the console *as is*, as there isn't a lot to it. I think my "review" topic is more of a "rolling information/observations" type topic.

I could video some Golden Axe 3 on tv-out maybe.. will see when I get home tonight :)

Maybe I was confusing a 3-D accelerator with the Graphics Engine it mentions there.  

@ omgmog

That's cool.  And while I am definitely into seeing the emulation, I would also like to see the games it comes preloaded with.  Though, I'm sure they are probably pretty cheesy, cheap clones of different games.  Call me crazy, but I'm into that kinda thing.   :)  But, do whichever you would prefer.  And keep up the awesome job.

Hi there, I`m new here. Hello to you all.

I bought a N350JP today from Chinavision, but something got my attention:

Quote
This next gen portable gaming systems is actually the third generation in recent portable game emulator advancement. In 2008 there was the Gemei X760, in 2009 the Dingoo A320, and now in 2010 we have the Letcool N350JP

It runs those machines:

Quote
Default Gaming Console Modes
- 3D Games (20 games included plus download even more from www.70game.com)
- GBA (Nintendo Game Boy Advance - 32bit)
- NES (Nintendo Entertainment System - 8bit)
- SNES (Super Nintendo Entertainment System - 16bit)
- Sega Genesis (Sega Mega-Drive - 16-bit)
- GB & GBC (Game Boy and Game Boy Color)
- Future Downloadable Gaming Consoles

...and the Dingo A320 says that it runs those machines:

Quote
Gaming Console Modes:
- NES (Nintendo Entertainment System - 8bit)
- SNES (Super Nintendo Entertainment System - 16bit)
- Sega Genesis (Sega Mega-Drive - 16-bit)
- GBA (Nintendo Game Boy Advance)
- Neo-Geo (SNK Neo-Geo)
- CPS1 and CPS2 (CAPCOM, arcade game systems, 1st and 2nd edition)

but my question is: If this is *really* the next generation, will N350JP be able to play Neo-Geo and CPS games too? Have anyone tried it ?
Title: Re: Letcool Gamestation
Post by: BonesCollector on June 17, 2010, 03:50:59 am
Do not believe everything you read.

Facts:
- Gemei X760, Dingoo A320 and A330 have the same kind of SoC: Ingenic [email protected] 336 ~ 400 mhz MIPS architecture.
- Letcool, PSP-clone and SPMP8000 devices haves the same kind of SoC: Sunplus80XX, ARM926 ~ 270 mhz ARM9 architecture.
- None have 3d acceleration.
- The "next generation" are GP2X WIZ and Pandora because they have a really fast CPU (530 ~ 600 mhz) and 3D hardware acceleration.
Title: Re: Letcool Gamestation
Post by: oilusionista on June 17, 2010, 01:46:18 pm
Thanx,

So Letcool is inferior than A320. That is bad :(

Have anyone tried to run Neo-Geo or CPS games on N350JP ?

I found a site with many emulators for A320, I wonder if they works on N350JP http://dingoo-a320.dcemu.co.uk/  (its ok to have link to emulators, nor roms, right?)

There will never be a dingux port, as dingux is developed specifically for the ingenic/chinachip/dingoo hardware. the dingoo cpu is a mips-based jz47xx, where-as the letcool has an arm-based spmp8k system-on-chip containing an arm926.

There might be some kind of Linux for the Letcool in the future, and it would be entirely possible, but booboo isn't the saviour for this, he was doing dingoo-related stuff and he has been inactive since November.

Doom does run well, but that's on native, and is probably helped by Alemaxx's porting.

You were the first to review it on chinavision ;)

Post by: jiraiya78 on June 19, 2010, 04:11:38 pm
That's is true but we still don't have any possible way of getting the eCos source from the Sunplus. I heard that someone ever tried to email them to get the source but to no avail. Maybe you want to try that.

Other than using the eCos source, the most possible way is porting directly source-available emulator into BIN application. Like porting snes9x, drpocketsnes, gpsp, virtual gba or other emulator. I think the most critically unplayable emulator is GBA and SNES. But porting this could prove to be difficult because of the SDL/layer/library thingy.

Someone with enough experience with this maybe could explain how hard to port emulator to here.

maybe they can contact right people about firmwares and whatever else is needed if someone knows what to ask for which i dont sorry

also can anyone make sense of this?

I made a quick video using nokia mobile phone 2MP camera, look crappy though. Tried out the new Windows Live Movie Maker also. Quite neat for a free video maker.

This is not Letcool though but other kind of generic SPMP8000 PMP. The screen is 4.3" so it is widescreen. A bit stretched but not very obvious. The button problem is the same with Letcool (except the shoulder button acting weird as volume +/-).

but it's next to useless for anything with shoulder buttons, since the shoulder buttons only change the volume.
get a dingoo a320, it's more powerful (supposedly), it has a million more applications and emulators available for it and it community support is on going. the letcool, currently, is only really useful for people trying to hack it. if you don't know how to do that then it's useless as a gaming machine at the moment.
Title: Re: Letcool Gamestation
Post by: TheCaffeinator on June 24, 2010, 03:59:39 pm
I wouldn't go as far as to say the LetCool s "useless" as a gaming machine without properly functioning shoulder buttons, but I do agree that  the shoulder button issue is a big deterrent. If they released a fixed firmware, I'd probably get a LetCool... but not until then.

The shoulder buttons are/were my big gripe about the A320. Although they function properly in-game, they're kind of crappy as controls go and aren't really suffiecient for GBA or SNES games that require heavy use of them. I have to say, though, that that doesn't make the A320 useless as a gaming machine, either. Truth be told, 95% of the games I play on my A320 don't use the shoulder buttons as in-game controls; as for the remaining 5%... for GBA games, I remap the keys ((X=A, Y=B, A=R, B=L), and for SNES games, I tend toward games that don't require heavy shoulder button use.

I had high hopes for the A330 because of the shoulder buttons, but the whole A330 thing hasn't quite worked out for me.

lol.

If you could boot a working kernel on this, you can map all buttons to whatever you want, eliminating that bug. I'm guessing the bug lies in the LetCool native firmware, and that the buttons are wired separately.

I heard the LC SNES emulator is shit anyway, Snes9x should be portable to ARM.

IMO, getting a working Linux kernel on this device has higher priority than some shitty proprietary SNES emulator :)

While i do aggree that linux is the first big issue that needs to be tackled, geting a better snes emu and fix the shoulder button issue are small things that will make the wait much more bearable. it may also get more people on board with the letcool if they see people releasing solfware to better it, it will get the ball moving and push more people to develop more stuff. plus i wanna play kirby super star.

Well if someone gets Linux to run on the Letcool you will be able to get Snes9x on that and have mappable buttons.

I been Following this for a while and i know that linux is the best thing for the letcool.
how hard is fixing the buttons? i wanna give it ago if someone would help me get started abit.

hello omgmog you said in the past

"Talking a bit with the folks in #Dingoonity on freenode, turns out the controller connection on the Letcool is micro-USB
if it's implemented correctly (and isn't just a cheap connection that looks like micro-USB) this *could* mean the Letcool has USB host."

has any one confirmed if it has usb host or not. Its a deal breaker for me i want to be able to play movies straight from 2.5 hdd
thanks in advance for any info.

confirmed that it physically has a USB host, and the spmp8000 chipset *can know* what to do with it, but there's no software to take advantage of it yet, beyond the multiplayer controllers.

if you wanted to get any use out of it other than that, you would need to fabricate an adapter, and write software to recognise mass storage devices connected to the port, etc.

If you could boot a working kernel on this, you can map all buttons to whatever you want, eliminating that bug. I'm guessing the bug lies in the LetCool native firmware, and that the buttons are wired separately.

I heard the LC SNES emulator is shit anyway, Snes9x should be portable to ARM.

True, but I think remapping the SNES buttons might be easier than trying to get Linux and then another SNES emulator on it for the average user.

You probably want to watch out for this table:
(http://img138.imageshack.us/img138/386/keytables.png)
and patch it. So the harder part is to find out its location.
If you patch the firmware file (the 8000MMI.RAP) you also need to update some checksums. Openschemes.com published an article about these MMI checksums ans also a tool to update/recalculate them here (http://webcache.googleusercontent.com/search?q=cache:hhXSAYP9b-sJ:www.openschemes.com/modules/wordpress/2010/02/04/spmp8k-a-door-with-a-lock-is-sometimes-less-secure-than-a-door-without/2/).

That's my dump of the Letcool firmware, and you don't need an account to download it. Wikia is just stupid about outgoing links, there is a "skip this ad" button.

This firmware dump is the same as what you will find on any Letcool, and the only way to flash it is using firmware writing software.

Should be working but from what I see in the IMG extract, there are some quite changing is the file. But I still haven't compare it with the previous bmorn firmware so I'm not sure what is new and what is old thing.

I'm not using bmorn but a generic spmp8000 shaped like PSP. It should be similar and should be working. Same goes for letcool. I couldn't test it in the near future so I couldn't give much comment on this.

Im using an old cellphone data cable based on a pl2303 converter. If you have got a soldering iron (which you would need anyway to solder some cables to the letcool pcb) and one of these cables you can modify it easily. One potential problem I encountered was that I had to supply an i/o voltage to the pl2303.

Hi I'm new here so I hope I don't get in trouble for bumping an old thread but after reading 17 pages this seems like the right spot for it.

I lost my old Dingoo A320 and this Letcool seems like a more than suitable replacement but I was wondering:

Does this quote still apply considering firmware 2.0 and that custom russian firmware that got posted up a couple weeks ago?

For the Emus themselves, of what I've tested so far:

 NES - Very nice as you would expect detected a little slowdown in some games that the Dingoo does not have.
 GB - Again very nice SMB Deluxe doesn't work like on Dingoo Native but others I tested ran  perfectly.
 GBA - A big step down from dingoo. Games are very choppy and with the button mapping issue. Not Good.
 Snes - NOT playable without mini pads. Game performance is hit and miss. Less sound issues than Dingoo native but feels slower.
 MD - A definate step up from Dingoo native, games ran much smoother and with less sound issues.

 Initial findings are that two player MD is this units early strength. With any luck a firmware upgrade can fix some of the other issues. The manual gives instructions on how to do firmware upgrades so hopefully one will be released soon.

Have the updates improved any of this? Cause if I remember right, while I loved my Dingoo, GBA emulation was the only one that was truly perfect (as perfect as emulation gets anyway). While games such as SNES's Chrono Trigger and Super Mario World would kinda lag. So have the firmware updates for the Letcool improved it beyond the Dingoo, or would the Dingoo still be a better bet for SNES?


Also it's probably waaay too early to ask about this but since I don't see it mentioned anywhere else in the forums, is it possible that the added ram for the Dingoo A380 makes things run smoother or is that not how it works? The link below has the specs, and I think there are youtube vids of it as well though I doubt any have shipped yet.
http://www.etronixmart.com/dingoo-a380-mini-console-2players-gaming-wireless-controllers-p-793.html

Thanks for the help  ;D


After some more forum research, I see that ram only really affects, Dingux emulators and not the native emulators, still good to know though
Title: Re: Letcool Gamestation
Post by: 1wiierdguy on February 03, 2011, 10:49:48 am
 Later firwares have improved Letcool performance and button mapping. The A320 still has better emulation though.

After some more forum research, I see that ram only really affects, Dingux emulators and not the native emulators, still good to know though

 This is true for Dingoo A330 because the native firmware wasn't updated to use the extra ram. If the A380 firmware and emulators have been moddified to use the ram it will make a difference. Just have to wait untill someone gets their hands on one.

 The camera not up to standard for capturing holiday memories. The Letcool can support up 32GB micro sd. Nes emu runs a bit too fast, Snes is ok but some games can get choppy, Genesis Gameboy and Gameboy advance run pretty good. All up the Dingoo still outperforms the Letcool for range and quality of emulators.

 Try the version 3.0 firmware from the multimix magic site. There must be two different screen versions in the letcool. If screen is off centre in 3.1 go to 3.0 and vice versa.

Download version 3.0 firmware, rename to 1.img.Replace the 1.img from the 3.1 files from my upload then put all files on root of memory card and update Letcool as usual.

Pictures taken are 320x240.  You can set it higher, but all it does it expand the 320x240 pic.  (Meaning it's still the lousy quality of a 320x240 pic no matter what size it is.)

I also had the screen off center problem with the 3.0 & 3.1 Defender firmware after system repower.  I tested a few SNES games and I couldn't detect any performace improvements, myself, so I don't think there's any loss in going back to the custom firmware.  I did flash back and forth several times with no bricking on my unit.

Just now found another place selling it for $23.95 (before shipping): http://www.elite-electronix.com/mp4-players/letcool-multiplatform-handheld-gaming-entertainment-station
