You could just download the SPC of the game and use Winamp to convert to WAV. The problem I find is if that certain SPC does not have a time length and just repeats forevere, you have to sit and monitor how long you’re extracting … or you can end up with a track that’s at least 5 Gbs big.
Hope this helps.
To get you started, just google the name Zophar. That place has lots of SPCs and other formats.
