I have arcade cabinet with pi2 retropie 3.5 and ipac2 for controls. Configured retroarch controls and mame fine but cant figure out mupen64plus. The InputAutoCfg.ini file wasnt there(im guessing because i havent connected a “controller”,just the ipac) but i put one in from another pi that i had connected one to. With that it gets input from a keyboard but not the right buttons. I cant run jtest on the ipac so how do i find the key id’s? ex. key(104)
Has anybody had success with ipac on mupen64plus?
