Unfortunately, this project has come to its natural end.
Dead mantis was kind enough to ship me an original SB Live! card to use in the system. While it took a LOT of work to track down some drivers with full support for the card, it did happen. The problem is this. After running the EQ client with the card installed, the music sounded no different than the mp3 recordings I made over 6 years ago by simply uploading the eq soundfont into my Audigy. In other words, that seems to be how the music really did sound a decade ago. No extra instruments, no fancy reverb, nothing. I guess age has colored my memory of how the music used to sound. Though I was hoping it would sound more like those ancient recordings from the EQ website back in 1998.
I will reupload the mp3 collection when I can find a place to host it. Until then, its basically the same mp3 files found here:

If anyone has any music related questions, or wants me to test something running on a 2000 era client before I dismantle my contraption, please ask.
