vWii

From RGDWiki

vWii (or Virtual Wii) is the fanmade name for the emulated Wii mode of the Wii U. It uses modified IOSes and a modified Wii System Menu to account for changes in the Wii U's hardware and the virtualized environment which is booted directly from Wii U mode using a technique called cafe2wii.

vWii encryption

vWii-specific titles, including System Menu and IOSes, use a new keyslot not found on the original Wii.

  • Key slot 0: Wii common key
  • Key slot 1: Korean key (located in SEEPROM at 0x74)
  • Key slot 2: vWii key (located in OTP at 0xD0)

Boot process

vWii lacks the Wii's 3 bootloaders (boot0, boot1, and boot2); instead, the Wii U launch code (cafe2wii) directly launches vWii IOS and the System Menu. This can be used to boot into a custom title other than the System Menu such as a particular channel or homebrew app.
