A friend of mine is having problems with the edge connector on his Nibbler cab, and since he'd like to be able to play other games in it, we figured on just replacing the edge connector with a JAMMA connector (he's got an adapter board to run his Nibbler PCB in a JAMMA cab). Anyway, looking at the pinouts on crazykong.com, most of the Nibbler pins have equivalents on the JAMMA pinout. What do I hook up "reset" to (or is it even required?), and on JAMMA, there's video gnd and "spkr -", whereas there's nothing for either on the Nibbler pinout. Should I just hook both video gnd and "spkr -" to gnd? Also, Nibbler doesn't use -5V, and there's a place for -5V on JAMMA...will that make a difference on other PCB's if it's not there?
