I don't think it's a JZ4780. They said 1.5 GHz, which matches the M200 better (1.2 GHz + 300 MHz dual-core).

By that logic it could be a JZ4770 at "1GHz CPU + 500MHz VC-1/VP8 core". If it's actually an M200 running at 1.2GHz it would be just as welcome. Though both chips have both been mostly MIA for the last 5 years. I haven't heard that M200 supplies have been any better than JZ4780.

FWIW, I had explicitly heard the board was supposed to have a JZ4780 chip. Of course, that's hearsay, so we'll see what they actually come out with.

It could very well be a JZ4770, yes.
A JZ4780 would be great, but I'll believe it when I see it.

Better don't buy from this lousy reseller. Official aliexpress shop and other aliexpress reseller are the way to go.

Oh yeah, i must note that the GK350H does not use the JZ4770, M200 or JZ4780 :
It is in fact an almost complete clone of the M200.
It has a single mono core clocked at 1.5 Ghz, supports the MXU & MIPS32r2 (according to kernel) and (as i suspected) lacks a 3D GPU of any kind of like the M200. I'm not sure about cache size but i believe that it should be either 256kb of L2 or 512kb.
Apparently whoever made this cpu thing is GameKiddy but this source says its made by Junzheng instead :
https://tieba.baidu.com/p/6279590671

"Junzheng X1830:
Main frequency: 1.5G, 28nm process, 11x11mm package size
Built-in DDR2 memory, 64X16 (128MB)
Graphics processing: IPU, no GPU
No HDMI and AV interface"
"Because the 350H motherboard does not have DDR2 memory, it is using the built-in 128MB DDR2 of the CPU."

Yeah, it only has 128MB of DDR2 ram. Don't expect to go full out on MAME and huge arcade roms thx.

I feel very mixed about this finding and i'm almost certain they won't release the kernel source code for it either.
It's possible that they made this clone due to supply issues of the JZ4770.

So yeah, don't expect to run Mupen64Plus on it because it simply lacks a GPU for it. However, the extra CPU power might be more interesting for some heavy SNES games. It can also mostly handle games like MGS well as you may have seen from other videos.

By looking at the link gameblabla kindly posted, it seems they are making a 512MB SWAP on the SD Card, which will be slow as hell.

That being said, both first Xbox and PSP were able to achieve pretty good emulation for larger arcade games by using cleverly programmed swapped partition.

I still don't really see the point of releasing a device that seems to excel mainly in PSone emulation but without proper L2/R2 buttons.

128MB is fine for most MAME games (circa Mame 084), most likely whatever is larger than this can't be handled by the CPU anyway.

I ordered my RG-350 so once I've tested it with XMAME 2.0 I will release something for it and a couple other Platforms.

Can someone please vouch for (or shoot down) RetroGame300.com as a seller (of the RG350)? No one on eBay carries it yet, and AliExpress (the apparent preferred source) doesn't like PayPal.  Thanks

Well consider me misinformed. I'll just ask Anbernic for their relevant info. Thank You.
EDIT: Oops my bad. The error is on my end, for using Firefox with adblock broke AliExpress. Chrome worked fine, though.

It was a joke dude

As far as I know paypal isn't accessible in China

thus any seller there who wants to refund you through paypal are often want to scam you and to avoid bad rating from aliexpress

I got scammed once with that modus operandi, luckily it was a cheap stuff. Think it was a handphone case, less than $5.

Friends, please tell me what is known about the defective party RG 350?  I ordered a copy for myself and it is already coming to me, I hope it will be of good quality.  And the second question is, can we wait for updates and adding new emulators?  I'm interested in the J2ME emulator of old button games from mobile phones.

I've preordered mine in early september, back then we didn't knew the RG350 would be availlable in different colors, today they've sent an email asking me what colour I want (or more precisely, telling us the three color options and asking us to mail them back with our choice).
