Everything seems to be running great with my big box arcade cabinet setup except 1 game, Toobin. The original arcade game is 5 buttons (paddle left forward/back, paddle right forward/back, and fire in the middle). It is also a 2 player game. This is fine for me as I built the cabinet with 8 buttons for each player. The problem is in Toobin with MAME emulator, player 2 doesn't exist on the controls. Player 1 is assigned to both joystick and buttons so it is very awkward for gameplay. How can I re-map the controller inputs for this one game without affecting all the others that work great?
