Well.. I finally figured it out. I heard the mix, and it sounded remarkably familiar, despite the firm knowledge that I'd never played the game before. I decided to take a look at the game for myself. After viewing a screenshot, I was startled by the likeness it had to another game I had played. I did some research, and found out that Fury of the Furries was remade and released for the PC in the US as Pac-in-Time(which is very different from the SNES version, and differs from Fury of the Furries in story, some graphics, and game physics).
I also tracked down a MOD of the original song this was based on, and I have to agree. It is quite nearly identical to the original. I've listened to the original and the remix back to back, and though I could tell you which was which, I wouldn't be able to tell you until a full minute into the song, and if you asked me in a week, I wouldn't remember the differences, because they are very specific and very small.
As a track, this song rocks. As a remix, it's a very minimalist approach. I don't pretend to be an expert though, and my ear is untrained, so maybe there are more differences than I can detect.
