Argh, dan_death actually did this (either mostly or fully) a couple years back. And my inability to remember to archive these things being what it is...
Anyway, a utility called "PSound" should be able to detect the samples. I remember very distinctly that dan_death was able to pull the music track samples, but I can't remember for sure whether all the environmental and in-battle sound effects were easily accessible. Vehek, utunnels, or alfadorredux may have looked into this more than I have by now.
EDIT: Hah, we did save a text file that dan_death made, at least. Looks like a series of file numbers.
