This is a carry-over from the Ultimarc forum. I just upgraded my cabinet from Windows 7 to Windows 10. Now that the upgrade is complete all controls have been reversed in MAME. Player 1 (Ultrastik 360) now only responds as Player 2 and vise-versa. The same problem happened with the Opti-Pac as well. MAME now sees the Player 1 trackball and spinner as Player 2 and vise-verse.
Anyone have a suggestion on how to revert them back? They were correct under Windows 7.
Side note: I just tried removing each device from Windows and now MAME only uses one trackball for games. Both trackballs work in the UI game select but as soon as a game starts it reverts to only using one.
