MKWII Yoshi sounds

I apparently have all character voices from the game as well, just not converted into .wav files yet (all of them are .rwav).

Too bad there are no .bank files that are converted yet. I could really use them. The .bank files are Dry Bones, Dry Bowser, Koopa Troopa, King Boo, etc., the character drafting noise, and sound effects.

MFGG is a good source to find Mario Kart Wii noises. There is a file that contains most of the voices.

I forgot where I got my sounds from, but they are ripped from revo_kart.brsar.

Dislikes the amount of neglect Toad receives...
Some of the sounds appear to be possibly cut as well. While going through some of the character's sounds, these characters appear to have voices that did not make it into the final version of Mario Kart Wii. Perhaps, we cannot hear it in the game, but it seems likely that some of the sounds were indeed cut.
