USB Loaded Brawl crashes once opponent is loaded in

[heavycube4u]

Hello,
I appear to have an issue with using custom characters in vanilla Brawl.
Every time I load into the game, I will properly load, however, if another character loads in, the console hangs and I am unable to do anything.
The custom character files were written into the game's ISO file and is being ran off of an NTFS formatted USB drive with USB Loader GX.
The codes also are active as well.
