I'm making myself crazy trying to find some documentation of the DEFAULT keymapping for MAME. I'm rewiring my four-player control panel and need the whole enchilada, not just the overview (P=pause, 5=coin 1, etc.).
I've looked at all my .ini files, looked on the MAME site, Google, etc., but no avail. The closest thing I can find is the one on the Ultimarc site, but it has a couple overlaps that I'm trying to verify (P2 button 4 is 'I', as is P3 joystick up).
Where can I find the official default MAME keymapping?
Thanks ...
