nielo360, can you try latest Retroarch from play store and tell me if controls are autodetected? I know XD uses a different joystick driver than q9 (xbox driver vs ps3 driver in q9), so not sure if new Retroarch can detect controls properly. Thanks.
Seeing the video it seems you thnk device is running at 1,2 ghz. If you can set 1,4 in setcpu then it's 1,4, but RK3288 has some temperature controls so that CPU can go down to 1,2 or even 1,0 after reaching a certain temperature. Most probably can be changed like in q9 and get 1,8 ghz, but it would require that GPD make free kernel source.
Also, another question. Can you swap internal and external memories like in q9 or is the memory unified with datamedia layout?
All in all, thanks for the video. Seems a nice device certainly.
