Hey Adalog,
I'm in Seattle (Greenlake) and have a Sega Lost World Jurassic Park with DMD strange behavior - parts of various screens are faded. It shows all is fine with the display tests in the diagnostic menus. I've replaced the display ROM, DMD, DMD power supply, and it does the same. My last thing to do is to swap in a known working DMD controller board. If I find that it is the culprit would I be able to bring it over for you to test and help me determine what needs to be fixed?
Thanks,
John Peters
