I've just recently done some testing, and it seems that I'm onto something. This may be easier than anticipated.
Previously, I mentioned decoding the entire file as one long wave file, so I could do the separating of the audio myself by hand with Audacity. That may just be possible.
I found a generic Gamecube ADPCM decoder, which managed to reduce approximately 90% of the static in the sound, nearly fully decoding the sound effects. The only problem was that the sound effects were too garbled. In theory, it would be possible to decode all the sound effects in one long wave file. I believe we've already figured out the algorithm to decode Rogue Squadron II's sound effects, so if someone could possibly implement the algorithm into a generic file decoder, I would be all set.
A HUGE thanks if you decide to help me out!!

Don't be too proud of this technological terror you've constructed.
The ability to emulate games is insignificant next to the power of the Force.
