Wii Homebrew Channel, which allows users to run unlicensed software on the Wii, is now available for the Wii U with some caveats. The news comes via Hackmii, which notes that the latest release of the Homebrew Channel will work within the original Wii menu that the Wii U uses for backwards compatibility. The release does not, however, work within the Wii U menu itself, something the hacking community hopes to change in the future, no doubt.
Naturally, tampering with consoles is something you do at your own risk (even if you're downloading official firmware updates, apparently). That said, if anyone manages to get the Fatal Frame 4 translation up and running, let us know.
