The emulator has received positive reception on its ability to play Wii U games on PC at higher resolutions than
1080p, the base resolution of the console, via the usage of community graphics packs. For example
Mario Kart 8 and
The Legend of Zelda: Breath of the Wild can be run in
4K resolution on compatible hardware. Many mods and enhancements have been developed for
The Legend of Zelda: Breath of the Wild; in August 2017, a hack to Cemu Emulator developed by Cemu community member Xalphenos allowed
The Legend of Zelda: Breath of the Wild to run at 60 frames per second (FPS), higher than the game's native 30 FPS limit. Unlike other emulators, Cemu was notably not
open source from its inception until 2022. Exzap explained that it allows for quick progress and for more control of its development. However, the decision drew criticism from other emulation developers.
Higan creator Byuu, later known as
Near, condemned the Cemu's closed-source nature, arguing that Cemu benefitted from the work of previous emulators without contributing back. Pierre Bourdon, a
Dolphin developer, also disagreed with its commercial status, expressing concern that high paying donors could influence the emulator's development team to favour certain bug fixes or games to support. In January 2022, Exzap revealed Cemu's roadmap, stating that Cemu is planned to go open source in 2022. Seven months later, in its 2.0 release, Cemu became open source under the
Mozilla Public License, and introduced its first builds for
Linux, and later for
macOS. ==See also==
