Can u give it to me? Like post it and I coan put it in. and how can you see what codes are in a GCT?
One more, does Brawl Minus affect any of this? cuz thtas what I have, is Brawl plus better?
Sorry bout so many Q's Imma noob at this

Well I don't have to give the code to you now as the problem was a corrupt texture like you said.
Use Code Manager and open the .txt file associated with your GCT to view your codes. You can also use GCTEdit, but Code Manager should really be used instead. I don't even know what the point of GCTEdit is because you're supposed to edit and view codes with Code Manager.
No, I don't think what codeset you use matters when stuff freezes. Also I use Brawl Minus too and everything is fine.
Great! See I told you lol.
Ok so Im doin 1 at a time now and theres somethin rong wit Marth and Ike. Right when I go on their icon it goes BEEEEEEEEEEEEEEEEEEEEEEEEEEEEP. Any idea y?

When you're on the CSS and mouse over their icons you get a freeze? It's probably a bad texture. I've had it freeze whenever I chose Captain Falcon's red costume. Remove the textures you have on Marth and Ike and see if you can select them.
