The '''Wii U''' is an eighth-generation console released by Nintendo on November 18, 2012, at {{Inflation|USD|349.99|2012}}. It has a 3-core IBM [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#PPC_CPUs|PowerPC]] CPU at 1.24 GHz with 2 GBs of RAM and an AMD Radeon GPU. It is the first console by Nintendo to output high-definition (HD) resolutions, such as 720p and 1080p. It includes a tablet-like controller, known as the [[wikipedia:Wii_U_GamePad|Wii U GamePad]], to provide certain additional gameplay. Notably, it can play all [[Wii emulators|Wii]] games as well as support the Wii Remote controllers for native Wii U games.

===Comparisons===
;[[Cemu]]: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.

:[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.

Also it supports [[Wii_emulators#Hardware_Features|Wii games that allow you to connect to the DS]] if you're gonna play them on the WiiU.<ref>[https://old.reddit.com/r/wiiu/comments/244gqn/can_i_connect_an_original_ds_to_the_wiiu_when_its/ Can I connect an original DS to the WiiU when it's in Wii mode?]</ref>

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>

====[https://skylanders.fandom.com/wiki/Portal_of_Power Skylanders Portal of Power]====
[[Cemu]] can communicate to the USB device directly if you have the Skylanders portal even though currently it has [https://wiki.cemu.info/wiki/Skylanders_Portal_FAQ#Known_Issues minor issues]. There is no official Skylanders portal emulation for [[Cemu]] at the moment, but you can use [https://www.youtube.com/watch?v=Fw-JhDFvP1M this unofficial modified version] which has an emulated portal of power included.

There is a [https://github.com/cemu-project/Cemu/pull/971 pull request] for adding "Skylanders Portal of Power" emulation to cemu though.

====[https://lego-dimensions.fandom.com/wiki/Game_Components#Toy_Pad LEGO Dimensions Toy Pad]====
[[cemu]] can communicate to the USB device [https://wiki.cemu.info/wiki/LEGO_Dimensions#Configuration if you have the Toy Pad]. Just like [[PlayStation_3_emulators#Peripherals|RPCS3]] there is no Toy Pad emulation for the [[cemu]] at the moment but you can use [https://github.com/Berny23/LD-ToyPad-Emulator#installation LD-ToyPad-Emulator] for that.

==[[Dolphin]] support for Wii U==
You might have read about an unofficial branch of [[Dolphin]] with Wii U support — but don't get your hopes up. While the [[wikipedia:PowerPC|PowerPC]] architecture in the Wii U is the same as the [[Wii emulators|Wii]] and [[GameCube emulators|GameCube]] (this fact alone was the reason why Wii emulation was added to Dolphin. It was originally GameCube-only), this support is nothing more than the file viewer features (region, internal name, various info, list of files and folders inside ISO and a way to extract them) being expanded to Wii U disc images. Nothing has been done on the actual emulation front as far as Dolphin is concerned, and the Dolphin developers have said that they are not interested in adding Wii U support to Dolphin.
