Simpsons: Hit and Run by wolupgm6 at 4:33 AM EDT on June 5, 2011
Firstly, inside the hrf files are rsd files. They're signed 16bit PCM files, little endian, 24000hz. They don't play with vgmstream as far as I can tell, my version may be a little outdated so I can't be entirely sure.
Here's an archive with one of the rsd files, and an mp3 version I quickly converted for reference: http://www.mediafire.com/?5jog0r26fgpzae5
And lastly, for those who simply "cannot be bothered" with the whole thing, here's an mp3 version of every file in the music archive. All named as per their original file names: http://www.megaupload.com/?d=NRTQM7WS
I thought about uploading a lossless version, but given the quality of the originals, 192kbps was appropriate and showed no real signs of quality loss.
