Konami X-Men and Capcom Black Tiger PCBs not booting.
Got a couple different problems here. First and foremost being my newly acquired 4-player X-Men PCB. It boots up to 6F, 4E, 7C and 2D being bad. This sorta disappoints me as one of those is a surface-mounted IC, and I do not want to try replacing that beast! Would there be any other issue that could cause this board to give a false negative? It seems odd that 4 chips in a group would be bad.
Secondly, I have a Black Tiger PCB that gives no life at all. No boot, no screen, not a peep. Where should I start on that board?
