I have 5 system 12 boards and the contrast, r, g, and b values in the test menus are all different. As far as I can tell, there's no way to reset to a default value.
Is there a common default value across every game? What is it? I tried looking at manuals but that didn't get very far. Maybe I'll try mame.
