Change one button for an emulator

[Anonymous]

Hi,

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”
to
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?

Try
input_player1_y_btn = “2”

make sure the quote symbol is correct first though.

Or you can try remapping:

Thank you, worked perfectly. I had the wrong syntax. My Retropie is coming along just nicely :)
