I'm a n00b, having recently purchased my first couple of cabinets. My JAMMA cabinet is a Primal Rage conversion, which is a JAMMA+. As far as I can tell from the pinouts, the Primal Rage board is the same as the standard JAMMA except that it uses pins M and 11 for the right speaker, and pins CC, DD, 25, and 26 for additional controls. The pinout is attached.
My questions is this - does it hurt anything to have these additional pins in the harness when swapping boards that do not requrie a connection at those points? I would think that standard JAMMA boards just wouldn't have anything traced to those spots on the edge connector.
I ask because I was unable to get either of my two boards to work in the cabinet. One had no sound (I would expect to have the left speaker only) and one had a bizarre video issue.
