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.
