The Wii U Menu is the main dashboard of the Wii U, acting as an application organizer and launcher. It is a graphical shell similar to the Wii's Wii Menu and Nintendo 3DS HOME Menu. It allows launching software stored on Wii U optical discs, applications installed in the internal memory or an external storage device, or Wii titles through the system's "Wii Mode".

Known Issues

Cemu can't launch system applets from the Wii U Menu.

Sometimes some software can't be launched and results in error code: 199-9999.

Required system files

Cemu now supports the Wii U Menu (with limited functionally) as of Cemu version 2.0-45. Additionally some system files are required.

If the proper system files are not installed into the mlc01 folder of Cemu, the game will simply crash upon loading the menu rpx file, men.rpx. The required files to get the Main Menu working can be dumped from the user's Wii U.

Additionally some system libraries from the Wii U SLC are required. These includes the nn_sl.rpl and drmapp.rpl libraries. For a guide on how to dump these files from your Wii U system, visit the Cemu System RPL Files site.

mlc01 folder

If selecting an option in the Main Menu screen and the required system files are not in the user's mlc01 folder, the game will output the error 155-0262. This is an error relating to save files.

This is likely due to me not dumping all the required files.
