'''xyzzy''' is a homebrew application which originally used [[PatchMii]] to download, patch, and use a version of IOS to extract the OTP Encryption keys for the [[Wii]]. The current mod now disables HW_AHBPROT, so it doesn't install an [[IOS]] anymore nor does it use PatchMii. It also supports USB devices, newer Wiimotes and GameCube controllers.
