I got a new to me Attack From Mars that has some missing P600G 6A 400 PIV diodes. Not sure why this is missing, but is it needed for this game? So far it seems as if everything is working.

If your GI is working, the back of that board has jumpers instead of the fat diodes.

Jumpers are fine. Fat diodes burn up, see the damage on your board.
