Ninja Gaiden Sigma/II soundtracks

Wondering if anyone’s taken these babies to task and tried extracting the music digitally. Ninja Gaiden Sigma has 19 new tracks in its sound test menu, which have never been released, and as yet, there’s been no word on a soundtrack for NG2.

Before someone links me to it, I already have the rip someone did of the new NG Sigma music. It may be a digital copy, but it’s not ripped from the game. Whoever recorded the tracks did not think to turn down the Sound Effects to 0 before recording, so every single track begins with the game menu’s percussive "select" sound. I have the file which contains the music from Sigma, and it has an AFS extension… however, existing tools for AFS files did not work on it. Is anyone here working on these babies?
