I have a NOS Boomer Rang'r conversion kit I bought a while back. I installed it in an old Dig Dug short cabinet with a JAMMA adapter card. It worked for a few days, but then the picture kinda froze with just part of the background showing. I installed it in another JAMMA cab and it shows a credits screen, but nothing else. Any ideas? Repair manuals for the Data East cassette games? Thanks.
