Bought a pacman board, when it arrived I see it was modified to work with a jamma adapter. I'm trying to get it back to original. My board has the diodes cut at D8, D7, D3, and D4. There's also a jumper wire in the upper left side where the large ceramic diode is. If I resolder those diodes back in and cut that jumper, is that all I need to do to get the board original again?
I know those diodes convert AC to DC, so I'm worried I might fry the board if I don't do this just right.
