I have been reading and reading and going in circles. I have setup retroarch, and of course, whichever controller I use, that is the controller that will work.
All I am trying to accomplish is setting up an NES controller to work with NES games, SNES for SNES games, and eventually Sega Genesis (I am using SEPARATE USB adapters for each system that I will plug in depending on which system I am playing). Which file do I need to edit? I added a controller config file (the controller name that shows up in emulation station when I proceed to setup the controller) to /opt/retropie/emulators/RetroArch/configs with appropriate mapping, but that did not work.
Please tell me what config file I need to edit! This should be easy but I’ve spent days and days and I am getting frustrated.
