<< Anyone know where those files are or what extensions they are? Any help would be appreciated. >>
Been a few years, but they are inside the .pk2 files I believe. Probably regular .wav files since I don't think they used mp3 back then... Just open each pk2 file, sort by size, and those huge .wav's are probably it. Also, the pk2 files are nicely sorted, so you will have all the music under a directory called something like "music" or maybe "sounds"...
