I recently started adding Gamecube ROMS to my Batocera build, but noticed a problem with them. I have been using a wireless xbox one controller via bluetooth to play games, and other than some finicky configuration, it's been great. I can open and close ROMs from other systems just fine using either the "Esc" key or through "Hotkey+Start" button, but neither seem to be the case for Gamecube. The only solution I've found is to reboot the system (which is another pickle because I'm building a new case for the system and have to close the circuit manually for each reboot).
Does anyone know of a possible solution for this? Will be working on it over the weekend at least, and I'm hoping to have the problem solved before the case is finished.
