I built this Supergun to occasionally test my PCB collection and to show the working one's I trade or sell here, Anyways it works great however on my favorite series (Mortal Kombat ) all the games get stuck. The board goes through it's rom chip tests and after all show green they get stuck on that screen while the game plays in the background (I can hear it on the speakers). Every MK PCB does this, every other board, Killer Instinct, gauntlet legends, street fighter....and so on all test and play fine. I'm confused by this as all the MK PCB's are perfect, test &play perfectly in their respective dedicated cabinets. This all started when I removed the isolation transformer from this test rig figuring that an LCD doesn't need that. Take a look and see if I'm missing something here.
