Cemu (short for "Café Emulation", "Café" being the codename for the Wii U[2]) is a closed source Wii U video game console emulator developed by Exzap running as the Core and GPU developer And Petergov Running as a core and audio emulation developer.[3] It was initially released on October 13, 2015 for Microsoft Windows.[1][4][5] Typically, the emulator updates once every two to four weeks, with Patreon supporters receiving updates a week before the public release.[6] Though it is still under development, it is able to run certain games smoothly.[7][8] In January 2017, it was reported that Cemu is capable of running games in 4K resolution through graphic packs.[9]


Developers of Cemu expected that The Legend of Zelda: Breath of the Wild would be playable with only a few months worth of work,[10] and had a rudimentary version of the game's tutorial playable within weeks of its release.[11] As of July 2017, the game is now fully playable and is able to be completed with physics, particle effects, and reduced crashes. Cutscenes are currently available with a community-made addon called Cemuhook. Also included in Cemuhook is an optional feature that allows performance increases at the cost of intermittent texture bugs.[12] On December 26, 2017, an update added support for multi-threaded CPU emulation, which enabled Breath of the Wild to be played at 60 frames per second.[13]
