Everytime I play a team game (versus, arcade, co op,) My other team mate always jumps off the map, leaving me 1v2 until I press qw to switch with him. How come?
you are using a character that has tag team built in.some people implement that code to try to emulate the versus style tag team.
depends on which character is, give us more details, was it a fresh mugen install or did you download one of those pack thingies that sometimes come with weird stuff already installed?
