Cafe OS is the operating system running on the PowerPC in Wii U mode. It consists of the Cafe OS kernel, the executable loader, and system libraries. Unlike on the Wii, where games ran with 100% CPU time, Wii U applications run under the supervision of a PowerPC kernel, isolating them from each other. All applications are [[RPL|modified ELFs]], as are the libraries themselves, and applications dynamically link with them to gain access to OS services. Cafe OS also contains a few system processes, like the home menu and error handler.
