Is there a cheat to get all red rings in Sonic Colors for Wii?

Yes, there is a cheat to earn Red Rings in _Sonic Colors_, but unfortunately, only works for the Nintendo DS version of the game. There does not seem to be a code yet released that works on the Nintendo Wii Version, or the HD remaster that came out in 2021 on PlayStation 4, PC, Xbox One, or Nintendo Switch.
