Hey guys. I know the term 'rare' gets thrown around a lot, but I have the "Turbo Ninja" version of MK1 and it really IS rare. I was playing it a while back and everything was fine, then the game just died.
I knew i wasn't the monitor because I lost all the game sounds and I could tell the monitor was still on. So, to eliminate the cabinet or the power supply as the problem, I installed another board and it worked fine.
I removed the Ninja roms from the board and installed the regular 5.0 (the board is T-Unit) and guess what...the game works fine. That meant that something was wrong with the Ninja roms and/or the extra little PCB that houses the security chip and clock crystal for UG12 (see pics).
I sent the roms to
www.hobbyroms.com and they said that they were fine. They even made me an extra set. So that just leaves the clock crystal or the security chip. I have no idea how either one of them could have ---steaming pile of meadow muffin--- themselves.
I need all your help in further troubleshooting/replacement of these parts. There are two LEDs on the pcb. the upper one indicates power. The lower one indicates activity. The lower one does nothing. If I remove UG12 from the daughter board and install in directly into the PCB, then I get the activity LED, but no game activity.
The roms, security chip, and clock crystal ALL have to work in unison. I am at an impasse because I don't know what else to do. It's not the PCB, or the roms. The security chip and/or the clock crystal has to have just crapped out. Anyone that can help would be extremely appreciated. Here are the pics and some info about the version if you are unfamiliar...
