Nintendo has wiped more than 400 Nintendo Switch emulator repositories off GitHub in a single day. First reported by TorrentFreak, the company filed seven DMCA anti-circumvention notices in one coordinated campaign, and the result was 401 repositories going dark at once.
What was taken down
- Suyu — the most popular successor to the collapsed Yuzu, and by far the biggest target. Because the reported network was larger than 100 repositories, GitHub processed the notice against the entire network: 311 repos.
- Skyline — the Android-focused emulator, around 29 repositories. Notably, Skyline was shut down voluntarily by its own developers back in 2023. The code simply outlived the project.
- MonoNX — a C#-based emulator, roughly 17 repositories.
- Assorted lingering Yuzu forks.
Nintendo argument
The takedown notices repeat a claim Nintendo has leaned on for years: that the repositories offer, link to, or otherwise provide access to Switch emulators, and that those emulators illegally circumvent Nintendo technological protection measures (TPMs) to run illegal copies of Switch games. Specifically, Nintendo points to prod.keys — the proprietary cryptographic keys used to decrypt Switch titles — and argues that distributing software relying on unauthorised copies of those keys amounts to trafficking in circumvention tools under the DMCA.

This is not new, and it is not over
The pattern goes back years. In May 2024, a single DMCA notice removed 8,535 Yuzu-related repositories. Yuzu developer Tropic Haze settled with Nintendo for $2.4 million that same year, and Ryujinx shut down that October. A further notice in February 2026 covered Yuzu plus at least a dozen other emulators.
And yet here we are again. Almost every project hit in this sweep was already supposed to be dead. They were forked, mirrored, or revived, which put them right back on Nintendo radar. As TorrentFreak noted, getting the repos removed is the easy part — keeping the code offline is the challenge, because forks tend to reappear faster than notices can remove them.
Why indie devs and preservationists are watching
For the open-source community, this is a familiar tension. Emulation is not illegal in itself — Nintendo has effectively acknowledged as much — but the encryption keys needed to actually run commercial games are where the legal exposure lives. The practical result is that a large volume of open-source code, including projects whose developers walked away years ago, keeps getting scrubbed from the largest code host on the planet.
For anyone building or archiving game tech, the lesson is blunt: GitHub is not permanent storage. If your project touches anything a rightsholder considers circumvention, mirrors and self-hosting are not paranoia, they are basic continuity planning.
Nintendo Switch emulator GitHub DMCA takedowns: your questions answered
Why did Nintendo remove Switch emulator repositories?
Nintendo argues that the repositories offer, link to, or otherwise provide access to Nintendo Switch emulators, and that those emulators illegally circumvent its technological protection measures (TPMs) to run unauthorised copies of Switch games. The filings specifically cite prod.keys, the proprietary cryptographic keys used to decrypt Switch titles, and frame distributing software that relies on unauthorised copies of them as trafficking in circumvention tools under the DMCA.
How many repositories did Nintendo remove?
401 GitHub repositories were removed in a single day, through seven separate DMCA anti-circumvention notices filed in one coordinated campaign.
Which Switch emulators were affected by the GitHub DMCA takedowns?
Suyu took the biggest hit with 311 repositories, because GitHub processed the notice against its entire fork network. Skyline (around 29 repositories), MonoNX (around 17), and assorted lingering Yuzu forks were also removed.
Is using a Nintendo Switch emulator illegal?
Emulation itself is not inherently illegal, and Nintendo has effectively acknowledged this. The legal exposure comes from the encryption keys and game files needed to actually run commercial titles. Nintendo position is that Switch emulators cannot function without circumventing its protections, which is the basis for its DMCA anti-circumvention claims.
Has Nintendo done this before?
Repeatedly. A single DMCA notice removed 8,535 Yuzu-related repositories in May 2024. Yuzu developer Tropic Haze settled with Nintendo for $2.4 million that year, and Ryujinx shut down in October 2024. A further notice in February 2026 covered Yuzu plus at least a dozen other emulators.
Are the emulators gone for good?
Unlikely. Almost every project in this sweep was already discontinued, then forked, mirrored, or revived, which is what put it back on Nintendo radar. Removing repositories is straightforward; keeping open-source code offline is the part that never finishes, because forks tend to reappear faster than notices can remove them.
