I just ordered a Ninja Baseball Bat Man pcb that I'll run sometimes in my Sunset Riders cabinet. My question is, is anyone familiar with what size auxiliary harnesses would be used for players 3 & 4. Konami boards use a 15 pin, Wrestlefest uses a 9 pin. The picture of the pcb looks like probably a 9 pin, but I can't quite make it out. Anybody know? If it's something different, I want to get a head start on making it so I don't waste $25 on what I can make for a buck.
Edit: playing around with this, but I can't find a manual scan online. Anyone know where I can find a complete manual or dip switch settings for the actual Irem board? I want to put it on free play so I don't have to keep coining up.
