Anytime I ever try to add a new char slot, it doesn't save it. Is there anything I don't know that would cause it to do this?

Is there an easy to use program to change where the actually portraits are located? If not, is there a way to do it in brawl box? I want to put all my chars that are in the same game's with eachother.

I'm having trouble finding the code/codes to allow you to select all the different chars(allows and such) Could someone please point me in the right direction? Would be greatly appreciated
