I recently bought a Dr. Mario arcade system with all docs and all stickers still on their backing from a couple that was selling off their motel and contents. I got it for $40, and the display only shows green except for one time, when it displayed in full RGB. By this picture, does anyone know if this is a play choice cabinet with a Dr. Mario board stuck in or is this an actual Dr. Mario cabinet (of which very few are known to still exist)? Either way it's either going to be sold for parts or modified to play NES/SNES games.

Additionally, if anyone has any ideas as to how to fix the color issue, let me know. I tried adjusting the gun lenses as it says in the manual (face the tube screen North, etc.) but it doesn't change the picture at all, and the fact that it did display properly once lead me to believe there's some wiring issues.
If anyone needs more pictures to determine this, let me know.
