Nintendo’s Relentless Purge: 400 Switch Emulator Repos Vanish From GitHub in One Day

Nintendo has filed seven separate DMCA anti-circumvention notices with GitHub, all on the same day, targeting Switch emulator repositories and their forks. Together the notices covered more than 400 repositories, TorrentFreak reported.

The largest notice targeted suyu, an emulator that gained popularity after Yuzu shut down. Because the reported network was larger than 100 repositories, GitHub processed the notice against the entire fork network, covering 311 repos. The other six notices ranged from a single repository to networks of a few dozen.

Same Argument Every Time

All seven notices make the same legal claim: that the emulators exist to bypass the encryption protecting Switch games, in violation of the DMCA. “During operation, the emulators at the reported repositories necessarily use unauthorized copies of these cryptographic keys to decrypt unauthorized copies of Nintendo Switch games, or ROMs, at or immediately before runtime without Nintendo’s authorization,” one notice read.

Each notice cites two precedents: the 2024 consent judgment against Tropic Haze, the company behind Yuzu, which ended in a $2.4 million settlement, and a Colorado default judgment last October ordering streamer Jesse Keighin, known as “EveryGameGuru,” to pay $17,500. TorrentFreak noted that neither involved a court ruling on the circumvention question on the merits. At the takedown stage, Nintendo doesn’t need a precedent anyway, and GitHub says it will “err on the side of the developer” only when a claim’s validity is unclear.

Dead Projects, Living Code

The sweep also cleared a network of 29 repositories for Skyline, an Android Switch emulator that was not a Yuzu fork and whose developers shut it down voluntarily in 2023. Its open-source code survived anyway, as did forks and mirrors of Yuzu, which settled in February 2024, and Ryujinx, which shut down that October.

Most of the targeted repositories now display removal notices, while some return 404 errors, suggesting their developers deleted them after being notified. Every emulator on the list was supposed to be gone already. For open-source maintainers and platform operators, the episode shows the limits of takedown-driven enforcement: removing repositories is routine, but keeping widely forked code offline is close to impossible.
