How To Rip Sounds Out Of Wii ISO's One Piece Unlimited Adventure

[Random Talking Bush]

Well, fiorst of all you're going to need a program that can browse ISO's and extract it's contents. I recommend MagicISO.
Simply (or well, simply? depends on the game) browse the ISO and look for a sounds folder. Then extract the contents you need et voila.

I hope this helped

MagicISO won't work with Wii games. You'll need either Dolphin or WiiScrubber to view and extract the contents.

Either way, look for a "BRSAR" file on the disc. If there isn't one, then there really isn't an easier way to extract the sound effects.
