Summary	08928: warfa and clones: In a linked operation, if one player challenges another player in singleplayer, the game freezes.
Description	Most of networking in War: Final Assault works except attempting to challenge another player in single player to a deathmatch freezes the emulator that was in single player mode. This doesn't happen on hardware.
Steps To Reproduce	This requires linking multiple instances of mame (single or multiple computers) with TAP adapters. For a detailed tutorial on how to do so, see here: https://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Board=news&Number=380959 1. Have mame #1 coin up and start a game in single player; wait till mame #1 goes ingame. 2. Have mame #2 coin up; this time, mame #2 will be given an option to either choose co-op or deathmatch. 3. Mame #2 chooses deathmatch 4. Mame #1 freezes; two possible results can happen with mame #2. 5a. Mame #2 immediately drops in deathmatch playing as nothing being able to look around but not move. 5b. Mame #2 freezes for a few seconds then drops in deathmatch with the other "player" not moving.
Additional Information	It's unlikely the network emulation isn't at fault here with this kind of behavior. Maybe a MIPS core bug?
