Crystal Frost in the magazine is a fake - the level was whipped out with many others for the show.

Jade Gully in the videos was a test level.

The "last" builds of Sonic X-treme were done using CartDev
Actual builds never even had anything but one level

The real Jade Gully:

As for me, I'm helping Chris Senn crack the map format to Sonic X-treme
The pictures above are from what I've already cracked
