I have been using a wired PS3 controller just fine with my retropie 3, but after having some sound issues for SNES i installed PiSNES as my new default SNES emulator.
Since this isn’t part of retroarch, i edited the snes9x.cfg file in the pisnes folder with what i believe are the ps3 controller button mappings. However when i launch a game in pisnes from emulation station, my controller and keyboard do not respond at all.
Is there another file i should edit? retroarch and ES work great with my controller. It’s just pisnes that is causing me trouble.
