FreePlay Zero Remap Controls

[Sithel]

Since I built my FPZ with no X and Y buttons how do I remap those on a per emulator? For example, seems like Mega Drive uses one of these when sega just uses A,B,C , I could remap C to left shoulder or right shoulder button. I tried coping GPIO controller config, just hte left shoulder input_l_btn = "2" to the retroarch.cfg in megadrive , but it doesn't work. Any help would be appreciated.

Thanks

I think what you want is explained (not in great detail) here: https://github.com/RetroPie/RetroPie-Set...figuration

I think you can also use the method explained here: https://www.reddit.com/r/RetroPie/commen..._only_one/

Let us know how that goes for you!

Thanks @Flavor, option 2 on the reddit post was the trick. It's all working now
