I'm glad you knew what Franchise5 meant Kremmit. The only "start" button I can think of is the 1P/2P button.
Yeah, there are cabs that start each player just by inserting a coin in the appropriate coin slot. (no 1P or 2P start buttons, etc) My Captain America was this way for four players, each coin slot represented a particular character to start.
Do I need to simply wire something from the 52 pin and wire it into a button of some sort that I would put on the door?
Look at the JAMMA pinout and you will see where 17 = 1P start and U = 2P start.
Add a pin and wire there if there isn't already one.
Then use any button you want to mount wherever you want.
The other side of the button just goes to ground like all the rest.
http://www.arcadetreasure.com/techinfo/techinfo.htmPlayer 3 and 4 start will go directly to another connector on the game pcb along with the player three and four controls. CN2 for player 3 on pin 8, CN3 for player 4 on pin 8.
Same thing, other side goes to ground.
Check the manual and see if it shows the pinout for those.
