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.
I have one that’s shaped like the SNES, it’s pretty good. The only issue I have is sometimes it doesn’t connect to my retropi and I have to remove it and reconnect it again.
