Help with custom css, swaps etc.

[Gthizzle]

I'm using Riivolution. Ok so I replaced Pit and Wolf with goku and vegeta including the sound effects and portraits for both and for goku, the stock, emblem, and css name. The game loads up and everything, I am able to play for a while but eventually the game freezes with the "beep of death". So far I took the sc_selcharacter.pac off the sd card and just left the common5_en.pac, however the game always ends up freezing after a while. I'm at wit's end of what the problem could be. Any help is appreciated!

Does it freeze when you are NOT playing with Goku or Vegeta?

No just when I use them
