      Set Up: rpi3 B+
      MAME 2003 Libretro .078 Set.
      2x Ultimarc IPAC2's
      2x HAPP trackballs
      2x Happ trackball adapters going to each of the IPAC's

      Here's the problem: When I attempt to play Marble Madness (the game only has two trackballs on the control panel and two start buttons) Player one rolls (Blue Marble) & Simultaneously rolls the (Red marble when engaged in a two player game) the Red Marble doesn't roll at all by itself. I think it's a matter of enabling "multi mouse" or two trackballs and assigning them to the .cfg but I'm having a tough time in doing so. Any suggestions to getting Marble Madness to work with two trackballs ? What specific config file do I need to modify, is it retroarch ? is it the mame 2003 / game specicif file that I need to point / and assign it that they are working interdependently ?

      My retroarch.cfg:

      My retroarch-core-options.cfg:
      "https://pastebin.com/embed_js/yPpYDgLa"
