I think it should be possible to decode it (not perfectly) as a single long file.
I would greatly appreciate any and all help, I can even provide a decoder for certain Gamecube ADPCM data that didn't work with Rogue Squadron II. Perhaps that could serve as a template if it's modified to decode Rogue Squadron II and III's audio format. It is only 69.9 kb in size.
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.
