Hey if anyone has any problems running this game try doing this:
1.Put the game on your C: drive
2.use windows compatibility modes, Windows XP sp3
3.install/enable DirectPlay
4. try downloading the game via the external one(mediafire) instead of the itch.io
that should work and you should be able to play the game.
one more thing, once you boot up to the character select screen once you select player 1 you will also need to select player 2 as well so you can fight.
