- Nintendo has managed to remove more than 400 Switch emulator repositories from GitHub in a single day through seven DMCA notices.
- The most affected project has been Suyu, with 311 repositories removed, followed by others such as Skyline and MonoNX.
- The company justifies the measure by arguing that these programs circumvent the technological protection measures of its consoles.
- This action adds to a long list of Nintendo's legal battles against emulation, with precedents such as the Yuzu case.
Nintendo has once again demonstrated its unwavering commitment to combating emulation. The Japanese company has succeeded in having over 400 code repositories hosted on GitHub removed, all related to Switch emulators. The operation, carried out in just 24 hours, primarily affected Project Suyu, one of the most popular emulators following the demise of Yuzu.
The legal offensive was launched through seven DMCA takedown notices filed on the same day. These notices had an immediate impact on the collaborative development platform, leading to the removal of 401 repositories that hosted or linked to these programs. This is not an isolated action: in May 2024, Nintendo forced the removal of more than 8,000 versions of Yuzu, and in February 2026, it repeated the move against the remaining copies of that emulator and a dozen other alternatives.
The project most affected by the new wave of DMCA
The purge has been particularly aggressive toward Project Suyu, a successor to Yuzu. Of the 401 repositories removed, 311 belonged to this emulator, demonstrating that it has become Nintendo's primary target. Suyu had long been the most popular option after Tropic Haze, the team behind Yuzu, reached an agreement with the company in 2024 and shut down the project.
But the removal hasn't been limited to Suyu. The list includes Skyline, an emulator for Android devices , and MonoNX, a program developed in C#. Numerous forks and variants based on the original Yuzu code have also been taken down. When attempting to access these repositories, users now encounter a message indicating that the content has been removed and includes a link to Nintendo's complaint.
Nintendo's legal arguments
Nintendo, in its complaint, maintains that the repositories offer or link to emulators primarily designed to run Nintendo Switch games. The company argues that these tools illegally circumvent the Technology Protection Measures (TPM) of its consoles, a key argument in this and previous lawsuits.
To reinforce its position, the company explains that Switch games are encrypted using proprietary cryptographic keys, known as prod.keys. According to the company, emulators must use unauthorized copies of these keys to decrypt the games, which constitutes illegal technology trafficking under the DMCA. Therefore, distributing these programs represents a direct infringement of its rights.
Story of a chase: from Yuzu to Suyu
This new offensive is part of a series of legal actions that Nintendo has been pursuing for years. The first major battle took place in 2024, when the company sued the creators of Yuzu. The accusation was based on the fact that the emulator had facilitated the illegal downloading of titles like The Legend of Zelda: Tears of the Kingdom millions of times before their official release.
The case was quickly resolved with a settlement in which Tropic Haze paid $2,4 million in damages and ceased operations. Since then, the Japanese company has relentlessly pursued any project that follows in its footsteps, and Suyu became the next target. In this latest action, Nintendo has also cited that legal precedent to justify the mass removal of repositories.
The scale of the operation has also been made possible by a particular feature of GitHub. When a claimant alleges that a repository infringes copyright in the same way as the original content, the platform can process the removal of the entire network of forks at once, instead of acting against each project individually. This has allowed Nintendo to remove hundreds of repositories with just a handful of notifications.
The effect on the development community
Nintendo's actions have had a profound impact on the development community. Beyond the loss of the emulators themselves, documentation projects, bug reports, and a history of work have been lost in an instant. For the community, these repositories weren't just piracy tools; they also represented a significant effort in engineering and hardware research.
However, Nintendo doesn't seem willing to change its strategy. The company believes these kinds of actions are necessary to protect its catalog and its console, especially now that the 120Hz OLED model is on the market and the Nintendo Switch 2 is on the way . The "zero tolerance" policy against emulation isn't new, but it has become more relentless over time.
In any case, this operation doesn't mean the definitive end of Switch emulation. The source code for many of these projects has already been copied and distributed through numerous channels outside of GitHub. While the company may be making open and public development increasingly difficult, what it has demonstrated is that the battle against emulation is long and doesn't seem to have a clear end in sight. With each shutdown, new projects emerge that try to keep the scene alive, and the next news of this kind is sure to follow.
