So I've been play around with an android emulator I downloaded onto my old chromebook and discovered I can use my sega genesis six button controller on it. I was wondering are there any emulators that will let you assign the same button/command to multiple keys. I've been using it to play golden axe and if you press attack/jump together your character will do a back attack move. So the layout I'd want (if its possible) would be A B and C assigned to normal buttons but also B and C assign similtainously to either X Y or Z. Are there any emulators that let you do this kind of thing?
