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 full hardware access, Wii U applications run under the supervision of the kernel, isolating them from each other. All applications are [[RPL file|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.

+Cafe OS applications dynamically link with system libraries to get access to OS services. These OS services include memory management, graphics, audio, and controller input. All libraries are [[RPL|RPL files]], a modification of the standard ELF format with compressed sections and more Windows-like dynamic linking. The main system libraries are listed below, with some having their own pages of documentation:
+*[[coreinit.rpl]] - Kernel, memory, and FS
+*[[gx2.rpl]] - Graphics
+*[[snd_core.rpl]] - Audio
+*[[vpad.rpl]] - Gamepad input
+*[[nsysnet.rpl]] - BSD sockets
