Hey guys,
if you were considering getting a GKD350H metal or even the upcoming GKD Mini, i'm not sure if i could recommend it to you...
The beta opendingux firmware on the RG-350/RG-350M/280V/280M greatly improved performance, so much in fact that it comes close or outperforms the GKD350H...
On top of that, i found weird issues with vsync and even audio blocking not working consistently and sometimes being slower, sometimes being faster. I am unable to explain why it does that...
While it's possible that the GKD350H could run the beta FW someday, it's certainly not going to happen if they don't release the kernel & uboot source code...
That said, i still intend on ports for it from time to time so you can now find here :
https://gitlab.com/gameblabla/gameblabla-releases/-/tree/master/opk/350hI recently ported VBEmu to it, my vb emulator based on the libretro core itself based on Mednafen by ryphecha.
Looks quite ugly without IPU unfortunately.
