Thanks for the response
Like I said I had found the files but InputAutoCfg.ini is located at this path in my installation:
/home/pi/RetroPie/emulators/mupen64plue-rpi/test/
Do you know if I need to edit both that file and also mupen64plus.cfg located at /home/pi/RetroPie/emulators/mupen64plus-rpi to have the same settings?
I am also wondering if InputAutoCfg.ini needs to be moved from the current path and into /home/pi/RetroPie/emulators/mupen64plus-rpi instead?
I did find that my wireless keyboard is working for the one game I have in the n64 ROMS folder (Mario Kart) but I need settings for snes controller.
Can anyone give details for this?
