I've noticed that some Vault entries include an Ocarina Code that swaps sound effects between characters.
Example of what I'm talking about. (http://forums.kc-mm.com/Gallery/BrawlView.php?Number=23476)
Are there any codes for making a character to not have any sound effects (or at least use sound effects from a character that has no true voice, like R.O.B., Game & Watch, or Power Suit Samus)?
I'd like to know this too.
