CPS PCB in Jamma cab confusion... HELP!
Rocky:
Yes, to change JAMMA games all you have to do is unplug the old PCB and plug in the new one and the game will work. (you might need to tweak the power supply knob to get the 5v right )
The only other things you have to "match" are controls and monitor orientation.

You also often need to readjust the monitor for the new PCB. Don't bother if you are just tossing the board in to play a few rounds, but certainly adjust it if it is a long term swap.
