Nintendo has had more than 400 GitHub repositories tied to Nintendo Switch emulation pulled from the platform, after filing seven DMCA anti-circumvention notices on 17 August 2026. The notices, filed against Suyu, Skyline, Yuzu Android, MonoNX and several smaller Switch emulator repositories, are published in GitHub’s public DMCA archive.
The scale comes from how GitHub processes forks, not from Nintendo filing hundreds of individual claims. Once a parent repository passes 100 forks, GitHub stops reviewing each one on its own and removes the entire network in one action. Suyu’s parent repository had accumulated 311 forks, so a single notice against it wiped out the whole tree. Suyu began in 2024 as a continuation of Yuzu, picked up after Yuzu’s creators, Tropic Haze, settled a lawsuit with Nintendo and shut the project down.
How the Switch emulator repositories were removed
The other six notices covered smaller but still substantial networks. Skyline, an Android Switch emulator that is not built on Yuzu’s code, lost forks even though its developers stopped work on it in 2023, worried about exactly this kind of action; the source had simply stayed public and forkable since.
- Suyu: 311 forks removed with the parent repository
- Skyline: 29 forks, despite development having stopped in 2023
- Yuzu Android: 8 forks
- MonoNX: 17 forks
- A fork maintained by developer NicholasArvani: 14 forks
- A repository built around an early-access Yuzu build: 21 forks
Tom’s Hardware’s breakdown of the individual filings is the most granular account of where those numbers came from. Between the seven notices, GitHub’s fork-network rule turned what would otherwise have been a modest set of claims into the largest single Switch emulation purge the platform has processed, on top of the main Yuzu parent repository itself.
What Nintendo’s DMCA notices claim
Each notice makes the same argument: the emulators rely on unauthorized cryptographic keys to decrypt Switch game files, which under the DMCA’s anti-circumvention provisions makes them tools for defeating copy protection rather than ordinary interoperable software. GitHub does not rule on whether that argument holds; once a valid notice is filed, the platform removes the repository and, where the fork-network rule applies, everything beneath it.
Nintendo has now taken this approach against Yuzu, Suyu, Skyline, Yuzu Android and MonoNX, covering both the original Switch emulator and most of the projects that carried its code forward after each shutdown. None of that stops the code from existing: it has been forked and mirrored widely enough, on and off GitHub, that new copies are likely to surface under different names.
What is worth checking is whether Nintendo follows up against the mirrors that inevitably reappear, or against emulators for later Switch hardware as that homebrew and reverse-engineering scene matures. GitHub’s public DMCA archive is the place to watch: Nintendo’s notices, including this batch, are filed there and stay visible even after the repositories themselves are gone.
