# Mupen64Plus SDL Input Plugin config parameter version number. There I found the area where it talked about the joysticks and figured by trial and error that if I see on my controller a number (the buttons are numbered) I type that number minus one in the config file, and for the buttons I was not using I just leave it blank, as in ''.
The file I used to configure the controllers is: ~/.config/mupen64plus/mupen64plus.cfg
I myself couldn't run a GUI for mupen, so I ended up figuring out how to configuire it and run it in the Terminal.
