I am using Arch Linux, and I've already managed to connect the Wiimote to my computer via Bluetooth. Any advice on how to hook it up to mupen64plus? I'm new here.
Best case scenario, it would simply work (TM), since there already exists an autoconfig entry for the classic controller. Make sure that the mode parameter in your ~/.config/mupen64plus/mupen64plus.cfg is set to 2 for the input you intend to use. If it doesn't work automatically try to use some joystick testing utility (most desktop environments include one or e.g. https://github.com/Grumbel/sdl-jstest ) to find out how SDL registers your input and set them up correctly in the cfg
