Hi,
I managed to get all the .wem files out of a version of the game, those seem to be encrypted though.

Here are 3 files which are basically one song, and I in did not modify in any way. Btw there also were some .wem files which I was able to decrypt just fine with tools by hcs, those were mostly menu sounds though. Would be amazing if you could take a look.
