The hacking group responsible for one of the first major modchips for the original Wii claims to have successfully reverse-engineered the pieces necessary to run copies of Wii U games from external USB hard drives.
"Yes, it's real," the Wiikey group posted in an update on its website. "We have now completely reversed the Wii U drive authentification, disk encryption, file system, and everything else needed for this next generation K3y. Stay tuned for updates!"
The group describes the Wiike U, as it's being called, as "the first and only optical drive emulator" for the system, running a "powerful embedded Linux system" that is compatible with all regions and models of the Wii U. As described, the device appears to only play copies of official Wii U and Wii games, and not homebrew or hacked titles.
