OK…I’m refurbishing an old full size arcade. All the buttons are in and all good. Now I can’t get my Rpi B+ to recognize player 2 controls through the ipac2 in anything else but mame. I tried remapping all the buttons with the program supplied by Ultimark but still nothing. Oh and the trackball doesn’t work either. I tried changing “mouse 0” to “mouse 1” in the mame cfg but still nothing. Any help is appreciated.
