i cant bind any key retroarch with os v0.3
so I followed the retroarch mega thread after v0.3 update (with etcher)

but always not worked after make -j4

plz tell me what you need to solve

ps. maybe forum linked v0.3 os has a problem. so, i installed v0.21 and updated v0.3 in the game shell. then i can bind key with retroarch.
