I appreciate the effort, but I'm pretty sure that wasn't the remix Zaratustra used...
Dug out my old hard disk, and it looks like I deleted the level at some point, so it's lost to the sandstorms of time, as it were. Due to my own actions, no less.
I could do some forensics, but the important question was "does anyone still have it", and that question's been answered, so no need to do anything more. Thanks! Time to disappear for another 5 years.
