Ourloader is an application that enables playing retail Wii U discs from other another region, also known as freeloading. This circumvents region-locking.
USA/EUR/JP game discs can be played on any USA/EUR/JP consoles, without the region of the disc needing to match the region of the console.
Insert the disc from different region into the Wii U. Then, start the app and press A to continue. The game should start as if it weren't region-locked.
Some games still won't work due to using different language files.
The development thread and compatibility can be followed in the release thread on GBATemp.
