Thanks for the answer, i've tried different times with the same result the L/R buttons are always located at the X/Y buttons on the gamecube controller, and i have no idea what i'm doing wrong...

Hello, I'm using the gbi optimized for the ossc but i can't figure how to change the control scheme in order to use the L/R buttons properly, this is my cli file --format=hd60--scan-mode=non-interlace--control=1 what i'm doing wrong? thanks
