I have up for grabs as I dont use them at all..
Dragonball Z 2 PCB - Got this off ebay tested a and it powers on
Mortal Kombat 2 Sound Board and Main Board - Tested Working
Also have a Simpsons PCB with a small graphics glitch not sure how to fix it. The Game plays fine except for the one sections the graphic glitch is on. I am on sure someone can fix it but I have a feeling it would cost me the same as getting a new one to get this repaird or looked at.
So techinically everything is available can take pics at req of interested party of boards working. I will upload pics of the boards themselves in the next day or so.
