I took the time to rip the audio from the game, now it’s available for your listening:
This was done by feeding an optical audio cable into my Hauppauge HD PVR, which is then fed straight into my computer. As a result I get Dolby Digital 5.1 AC3 audio, which is as clean as it gets, short of extracting the game assets and converting it like that. Though upon examining the stream, it turns out the audio is 2-ch, with the back channels being nothing more than reverb. So the above files are only 2-ch AAC 192 kbps VBR audio, but enjoy!
P.S. I also normalized the audio tracks and did a bit of cleaning up with the Main Menu track to ensure it sounded great as a standalone track, but overall should be pretty much the same thing.
