On my Jamma harness, I have a white wire at Pins 25/c. Is it used for anything, like a Pause or an Exit?
 
unless you have the Konami to Jamma adapter.

Do you know if PIN 26 has any use??
 
3 per player... 2 players simultaneous, + 4 start buttons.

It probably maps P3/4 start to P1B4, B2B4

Well, I guess that could be. Although some buttons could also be mapped to the joystick inputs too. Not sure how you would actually wire it, as it probably doesn't have a real JAMMA conversion standard.
