So I'm at the tail end of my NBA Jam restore and conversion. Converting from a two player into a 4 player cab.
At this point, my only issues are A) no sound. Worked before, just troubleshooting what the hell I did in the process and B) I can't get it to show up as a 4 player. I haven't wired the 3 and 4 player wires to the CP, but I have the harness's plugged into the 3/4 player slot on the board and flipped what I thought was the right switches, but no luck.
I'm working off: rev 1.0 01/17/94
Would it be a pcb battery thing or weird pin mapping? I think the battery on my board must be dead by now.
Thanks in advance!
