Tab -> Input (This Game) -> Remap Player 2
This isn't working, it's still controlled by p1 controls
When the dipswitch is set to upright cabinet, MAME ignores the P2 inputs because on the upright cab P2 used the same controls as P1.
PBJ had the right idea, with the minor correction that you need to remap
player 1's controls to accept inputs from both P1 and P2 controls.
To program each P1 input to work with either P1 or P2 controls:
-- Highlight the desired input
-- Press Enter. Press Esc. (input = none)
-- Press Enter. Press P1 control. (input = P1 keystroke)
-- Press Enter. Press P2 control. (input = P1 keystroke or P2 keystroke)
