I got a SNES USB controller today for when I play Super Nintendo ROMs and was wanting to make sure I knew how to do this before screwing it up like last time. Last version I had I swapped it so square and x on my PS4 controller were A and B for NES as that’s my preference and it swapped those around for the menu and everything. I want to just set it up for SNES and maybe recustomize on NES without it interfering with other cores or the menu, how do I do this for sure?
Also, which CFG file is for controls? Is it the retroarch cfg? This way I can make a copy just in case.
