Okay, I have a really stupid question.
I added four admin buttons on the front of my control panel for Mame functions such as Exit, Service Mode, etc.
I have them wired to the "extra" buttons on my IPAC (1P button 7 & 8, 2P button 7 &

.
Can I change MAME to use those keystrokes to escape/pause/service/etc. or should I reprogram the IPAC to send whatever keystroke Mame wants.
I would imagine that it's easier to change Mame than reprogram the IPAC.
Also, these were the buttons I was thinking:
Service Mode
Menu
Pause
Exit (ESC)
Anyone have any better ideas?
