what does it mean to have 4 costumes per character?

I have read in a post that someone is tryin to get champion with the same character in the 1p and 2p costume so they can have a total of 4 costumes. How do you get an extra costume and are there any pictures of them? OR do they just mean some extra costume colors. DOnt u need to beat it just once to unlock the colors for both 1p and 2p costumes? Thanks

 

It sounds like they just want to have the same 2 costumes, but just set them up in different ways, giving them a total of 4 different costumes, i.e. 1p would be blue for the player 1 data, and red for the player 2 data.

 

wow that sounds liek a lot of work /versus/images/graemlins/laugh.gif
