The only traces of the English version of the site that I could find were through
archive.org and not everything from the site was archived.
Also, I have some of the "Who's That Turtle? Sweepstakes" commercials, a preview of the premiere, as well as the first sneak peak of the theme song and unfinished intro that aired on the FoxBox (which has some of the characters from other shows giving a go at it). I got these from the Ninja Turtles Network site in 2005, but it has been dead for a while now.
Plus, here's the countdown to the premiere that aired before the first episode, as well as Michelangelo making a funny comment about missing the premiere at the end credits.

Here's a playlist of some of the FoxBox Bios and a few advertisements as well.
