I have RP2 with Retropie3 built from the image written straight to the microSD card. I am using a Sega USB controller that uses playsegacontroller.cfg. I would like to change one button but only for the megadrive emulation (lr-picodrive). If I change the line in playsegacontroller.cfg (in \\retropie\configs\all\retroarch-joypads) from
input_y_btn = “4”
input_y_btn = “2”
I get what I would like but of course this now changes it for every emulator. I’ve tried adding this line to the retroarch.cfg in the megadrive folder (\\retropie\configs\megadrive) but it doesn’t change anything. Still learning but any clue what else I need to do please?
