I have an RG353V currently running ArkOS. Works great, plugged it into my TV and looks great there too. Tried both a USB Xbox controller and PS3 controller and neither seem to be recognized (both of which I know Linux kernel models exist to support). Wanted to pick up a couple of SNES style controllers (kids mostly play Nintendo games) but wasn’t sure if anyone could vouch for specific brands or models they know work on these platforms.
They have adapters for their wireless controllers, and I think you can use old controller shells and put new “guts” in to update them… if you have old controllers, of course!
