hm i personally thought this was some piracy tool but if the folks at the legit wiibrew site deem it as legit homebrew then ill waiver this for now.

CleanRip is a Gamecube and Wii optical disc backup tool for the Nintendo Wii.

The "Clean" in CleanRip comes from the fact that this tool does not require nor utilize any custom IOS (cIOS). It simply requires that you have the latest Homebrew Channel (HBC) installed. Also, if it finds that IOS58 is installed, you will be able to rip discs at USB 2.0 speeds.
