Now I'm more confused. Are you saying there's no way in MAME to prevent Lunar Rescue from flipping the screen for player 2? And, if so, is the same true for Polaris and Spectar? Is there a list somewhere of all games that will always (and irrevocably) flip the screen for player 2, thereby rendering them useless for upright MAME cabinets?
