Pr? - do we have verifiable proof on priorities?
Up? - have we updated to use new MO's & tilemaps?
VC? - does it use the video controller?
PF? - does it have a playfield?
P2? - does it have a dual playfield?
MO? - does it have MO's?
AL? - does it have an alpha layer?
BM? - does it have a bitmap layer?
PH? - does it use the palette hack?
