;[[Cemu]] <small class="plainlinks" style="font-weight:normal;">([https://compat.cemu.info compatibility])</small>:An initially closed-source Wii U emulator created in October 2015, regularly updated every 2 to 5 weeks. It can run a sizeable amount of games. As of 2022, Cemu is no longer in the experimental stage, it's now fully open-source, and a macOS port has been released.
;[[Decaf]]:Can boot some commercial games. It's developed sporadically.
;Kinnay:Emulates the Wii U processors and hardware at the lowest level. It's able to emulate all the way through boot1, IOSU, and Cafe OS up to the Wii U menu. Written by the leading Decaf developers, exjam and kinnay.

====Wii Mode====:[https://en-americas-support.nintendo.com/app/answers/detail/a_id/1162/~/how-to-switch-between-wii-and-wii-u-modes Wii Mode]====:[https://wiibrew.org/wiki/VWii WiiBrew: vWii]
The Wii U is compatible with all Wii games and Wii accessories such as the Wii Remote (Plus), Wii Nunchuk, and the Wii Balance Board. It is possible to migrate most downloaded software and save files from a Wii to a Wii U.
The Wii U is not compatible with GameCube discs or accessories, although a homebrew application for Wii Mode exists that enables GameCube hardware and GameCube controller support. A USB GameCube controller adapter with four ports was released exclusively for use with Super Smash Bros. for Wii U and does not support any other Wii or Wii U games.<ref>[[Wikipedia:Wii_U#Backward_compatibility|Wikipedia: Wii U's Backward compatibility]]</ref>
====Wii U Optical Disc====
The Wii U Optical Disc (WUP-006) is the retail physical game medium for the Wii U, with a capacity of 25 GB. There is no 50 GB dual layer version. The Wii U system software is backwards compatible with Wii Optical Discs, but not with GameCube game discs. The Wii U Optical Discs differ in appearance from most other optical discs in that they have soft, rounded edges.
Nintendo president Satoru Iwata stated, "Wii U does not have DVD or Blu-ray playback capabilities. The reason for that is that we feel that enough people already have devices that are capable of playing DVDs and Blu-ray, such that it didn't warrant the cost involved to build that functionality into the Wii U console because of the patents related to those technologies". Like with the GameCube and Wii optical discs, it was chosen by Nintendo to prevent copyright infringement of games, to reduce cost by avoiding licensing fees to the Blu-ray Disc Association (BDA), and to reduce loading times. This also prevents the console from being modified into a DVD or Blu-ray movie player.[https://en.wikipedia.org/wiki/Nintendo_optical_discs#Wii_U_Optical_Disc]
*cemu has no support for Wii U discs, PC optical drives can't read Wii U discs anyway.
*See [[Home_Media_Player#Emulators|this dedicated page]] for more information about home media playback support for emulation softwares.
