    Could you give an example of how that would work? Does that have to do with idle animation, or some other flag when the game realizes nobody's playing it? I remember FIO had idle animation for feeding fish in the water level that's not present in any of the other metal slugs.

    Nothing to do with animation or graphics. Its a flag that the bios uses to know the current player state (0x10FDB6 - 0x10FDB9). Its function is to know what players are not playing / playing / continue / game over.
