TODO:
- Get rid of those big lookup tables, I see no proms on the PCB so it's a color overlay?
- Get rid of those big lookup tables, I see no proms on the PCB so it's hardcoded
logic somehow, or a color overlay?
Note: warp1 colors more or less match the ones of dai3wksi according to flyers
- Two player games are automatically displayed in cocktail mode.
Is this by design (a cocktail only romset)?
