Many homebrew applications that run via The Homebrew launcher have been collected and hosted on wiiubru.com, which has a layout similar to that of the Wii U's own menu. These hosted applications can be downloaded directly on the Wii U using The Homebrew App Store app in the repository. Some of these applications utilize an IOSU exploit that was released by the WiiUbru team, which allows full access to any Wii U console. This IOSU exploit is often used to launch a console into a patched mode called CFW (custom firmware) sysNAND. In this patched mode, the system is able to launch any title, including unofficial titles and titles without valid signatures and Wii virtual console games or injections that are shortcuts to vWii (Wii Mode) games or homebrew applications. All of the current CFWs allow editing of files stored on the Wii U via an internet connection and an FTP application as well.
