VLC will convert them to mp3 successfully. It's a shame the bitrate isn't higher though, there's some quite audible aliasing at times :sad: Still, there's always that nice 4 disc soundtrack available!
Ok, so I've unpacked the Sounds BSA and extracted the music files...but they're in .xwm format. I tried playback in VLC which kind of worked (lots of skipping), can anyone point me in the direction of a converter for these files please?
