So I noticed something today and maybe someone can figure this one out and maybe it can create a solution for this problem. I bought an N64 controller today and noticed that when I played SNES games the X and Y as well as the right and left shoulder buttons worked. So when it loaded I noticed the file name: Generic USB Joystick and went to /opt/retropie/emulators/retroarch/configs to find the file to see how the buttons where programmed, but he file isn’t there in that folder. Anyone have any ideas as to where the file is then? And if so maybe that’s why when I modify USBGamepad.cfg it doesn’t fix the problem on the SNES controller?
