I would like to configure MAME such that whenever the original game didn't have P2 controls the P1 Controls are mirrored on my P2 controls.
I want this because on my narrow control panel there are some 1 player games where, for comfort, I'd like to use the P1 Joystick with the P2 buttons. I have set this up manually in MAME for some of my favorites, but it would sure be nice to have it done automatically.
I am running a newer release of MAME with a Minipac. Any advice would be appreciated.
