First post updated (thanks rot). The new MS3 dump is an earlier revision of the game. The later version (already in MAME) has 0x08 bytes inserted at 0x043874, it checks to see if a player is playing and skips some code if they are.

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.
