Patches released by developers to fix bugs, improve performance, or add features.

The Nintendo Wii U remains one of the most unique consoles in gaming history. While it suffered from poor commercial sales, its library contains some of the finest first-party titles Nintendo has ever produced. Today, thanks to the monumental achievements of the emulation community, playing these games on modern hardware is easier and better than ever.

WUP is an installer format intended for use on a real Wii U console. It is generally not recommended for emulation, as it requires installation to a virtual NAND and can be cumbersome.
