Hacks failing over Player 3 Slot

[silveruchiha]

I know this doesn't make a lot of sense, but I was going through new costumes for characters (replacements, updates, and attempting to fix ones that we thought didn't work).
Through my tinkering, I found out that certain costumes will not work when used by Player 3. Instead, the game freezes. Player 2 works fine. Player 3 works fine. But certain ones like Joker, Hitler, Deadpool, and even Banjo Kazooie will not function on player 3.
I can think of any codes or reason why this would be a problem. Has anyone else encountered a similar issue? If so, is there a way around it? Any help would be appreciated as I have a lot of costumes and it would suck if we had four players and one of us was stuck with the defaults I left on there (luckily).

Could it be your codes?  I know that when I use my hacks, they all work with all the player slots.
