Cemu is a free and open-source Wii U emulator, first released on October 13, 2015 for Microsoft Windows [1] [3] [4] as a closed-source emulator developed by Exzap and Petergov. [5] With the release of Cemu 2.1 on August 27 2024 it gained stable support for Linux and macOS. Though still under development, it is able to run the majority of games smoothly, assuming compatible hardware. [6] [7] [8] The popularity of the emulator spiked with the release of The Legend of Zelda: Breath of the Wild in 2017 as Cemu successfully booted and ran the title within hours of its release. [9]

Development

Designed as a proof-of-concept, the initial release of Cemu could successfully boot Mario Kart 8 and The Legend of Zelda: The Wind Waker HD yet lacked Wii U GamePad support and audio and suffered from stutters and video glitches. [10] Cemu could run on 64-bit Windows operating systems and only supported OpenGL 3.3 on release. Despite the Wii U sharing a similar name as its predecessor, the Wii, the emulator was built independently from Dolphin, a Wii emulator, as the systems only shared their CPU architecture in common. [11] The emulator would rapidly progress from this state and increase its compatibility with the Wii U game library and add more features.

A couple of days after The Legend of Zelda: Breath of the Wild released, Cemu was able to boot the game - though running at a sluggish framerate, without audio, and filled with many glitches. The anticipation for emulation of The Legend of Zelda: Breath of the Wild caused the emulator's Patreon to increase monthly donations to $7,400 per month [12] and later $22,317 per month. [13] Developers of Cemu expected that The Legend of Zelda: Breath of the Wild would be playable with only a few months worth of work, [9] and had a rudimentary version of the game's tutorial playable within weeks of its release. [14] Cutscenes were made available with a community-made add-on called Cemuhook, though Cemu 1.18.0 removed the need for the plugin. [15] [16]

Reception

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. [17] [18] Many mods and enhancements have been developed for The Legend of Zelda: Breath of the Wild; [19] 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. [20]

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. [21] In January 2022, Exzap revealed Cemu's roadmap, stating that Cemu is planned to go open source in 2022. [22] Seven months later, in its 2.0 release, Cemu became open source under the Mozilla Public License, and introduced its first builds for Linux, [23] [24] and later for macOS. [25]

The Nintendo data leak, also known as the Nintendo Gigaleak, is a series of leaks of data from the Japanese video game company Nintendo on the anonymous imageboard website 4chan. The leak started in March 2018, but became most prominent in 2020. Ten main sets of data leaked on 4chan, ranging from game and console source code to internal documentation and development tools. The name "Gigaleak" mainly refers to the second leak on July 24, 2020, which was 3 gigabytes in size. The leaks are believed to have come from companies contracted by Nintendo in the design of these consoles, and/or from individuals previously convicted of intrusion into Nintendo systems. An earlier, much smaller leak had also occurred in 2018 which contained the Nintendo Space World 1997 demos for Pokémon Gold and Silver.

Emulators of the Nintendo Switch, Nintendo's current eighth-generation video game console, have been in development since 2017, less than a year after the console's release. Multiple emulators have been in development, the most well-known being Yuzu and Ryujinx, both now defunct. Switch emulators have been widely noted by video games journalists for the swift and significant progress of their abilities to accurately emulate the console, as they are already able to run existing and new titles for the console in a playable state, sometimes within days of their release, as well as able to run on a variety of devices, including PCs running Windows and Linux, and the Steam Deck.

Nintendo is one of the largest video game publishers in the world, producing both hardware and software. Since the release of the Nintendo Entertainment System in 1985, the company has generally been proactive to assure its intellectual property in both hardware and software is legally protected. Nintendo's protection of its properties began as early as the arcade release of Donkey Kong which was widely cloned on other platforms, a practice common to the most popular arcade games of the era. Nintendo did seek legal action to try to stop release of these unauthorized clones, but estimated they still lost $100 million in potential sales to these clones. Nintendo also fought off a claim in 1983 by Universal Pictures that Donkey Kong was a derivative element of their King Kong in Universal City Studios, Inc. v. Nintendo Co., Ltd.; notably, Nintendo's lawyer, John Kirby, became the namesake of Kirby in honor of the successful defense.
