check the first post. one of the game developers accidentally left it inside their game's files. you need the game and a few special tools to get it, so you might try with the other tool, atrac3plus2wav.
it's easier to get (it's a free homebrew), and all you need is the program and free trial version of sound forge 9 for its driver to use it. both are linked in http://www.emunewz.net/forum/showthread.php?tid=129065
@gid:
while trying to fix the high pitched voice, can you also look at the at3/oma file naming/hashes? the emulator sometimes mistakes some files for others. i think the emulator will wrongly assume some files it's about to extract are the same as different ones it already extracted, maybe because of apparently identical hashes and will play the wrong file. the hash codes might be too simple, or there's some problem in their generation.
