Welcome to The Red Hat Café, where we hack some of our favorite games: New Super Mario Bros. U, New Super Luigi U, Mario Kart 8 and Super Mario Maker! You can make an account, or just browse the site and see what we're making.
At The Red Hat Café Wiki, you'll find lots of up-to-date information that will help you hack New Super Mario Bros. U and Super Mario Maker. You can submit your own findings there, too! Mario Kart 8 information is kept on the Custom Mario Kart 8 Wiki at Tockdom.
You can submit your own findings about sprite settings and behaviors in New Super Mario Bros. U and New Super Luigi U to our database. The information, containing the very latest findings, can be downloaded in XML form here.
You can't hack a game without the proper equipment. Check the downloads page to find the programs you'll need to get started. Then browse this site for compiled homebrew apps you can use to run your custom content on a Wii U.

Wii U System Menu Versions: Quick Reference
Both a userspace exploit and a Cafe OS exploit (commonly known as a "kernel exploit") are needed to run custom content on a Wii U. You can check your console's version number in the System Settings app. The official System Menu update history from Nintendo can be found here.
Please note: the letter at the end of system software version numbers is a region code: U is the Americas region, E is the Europe region, and J is the Japan region.
Private exploits will be made public in the future.
The information below is current as of September 25, 2016.
* An exploit is possible, but has not yet been developed.
