Sonic Unleashed Cheats for Wii
Enabling this feature requires going into already cleared missions and collecting ALL the secret items (except Movie 36).
At the start of the level when Sonic is counting down swing the Wiimote after he says 'One' but before 'Go' and sonic will boost out in a spindash to start the level.
When you have completed ALL the missions with S-Ranks the game's final mission will become unlocked. Find the hidden item and complete this mission and you will be able to view the 'Sonic Omake' cutscene.
When you have collected ALL the Art, Music, Secret Documents and Movies (except for Movie #36) the final Adabat mission will become unlocked.
This feature can be accessed if you enter Y, X, L, B, R, A at the 'Cheat Input option' using a GameCube controler.
On the Gamecube controller, if you press Y between 1 and Go you'll start out at a spin dash.
I heard in the game that there is one secret mission that is really easy to get in the game Sonic Unleashed. All you have to do is to get S-Rank in every single mission and collect all Sun Medals and all Moon Medals. Once that is done with,go to Adabat and it's time to do the Final Mission,you will beproud once you finish this mission which means you beat Sonic Unleashed one-hundred percent complete. Happy cheating out there.
