Here are the unreleased tracks from Sonic Unleashed that weren't on the soundtrack. This includes Windmill Isle Act 1 on the 360 & PS3 as well as the versions of the songs when you hit the boost.

Enjoy!

Interesting stuff.
Windmill Isle Act 1 compared to the OST Windmill Isle, I only noticed some instrument differences (OST had more, or..something)
The speed effect makes the songs pretty neat.
-insert "thank you" here-

Many, many thanks! Did you do this yourself? If not, where did you find it?

Yes I had ripped them straight from the 360 ISO.

Did you find anything else of interest perchance?

Voices from the cut-scenes are rippable in both English and Japanese but I'm having trouble ripping the sound effects from the encrypted .ARC files that store most of the data in the game. Maybe someone can help me out to access those files.
