Switch emulators: Nintendo takes down 405 GitHub repositories

Nintendo filed seven DMCA notices with GitHub on August 17, 2026; the platform cut off access to the targeted repositories on the evening of August 19. The tally reaches 405 Nintendo Switch emulator repositories: the largest batch ever published in a single day in the public github/dmca repository.

A single notice accounts for the bulk of it: 311 repositories from the Suyu network, the fork that emerged after Yuzu shut down. The other six target Skyline, the Android emulator (29 repositories), MonoNX (18), and four clusters of Yuzu forks: 24, 14, 8, and 1. All of them now return an HTTP 451 error.

Not a copying complaint

Nintendo is not invoking classic infringement here. The seven notices rest on Section 1201 of the DMCA, the so-called anti-circumvention clause: what's being alleged isn't the reuse of Nintendo code, but the use of the console's encryption keys (the prod.keys) to unlock Switch games. The debate is no longer about how similar the code is, but about what it does. Each notice cites the March 6, 2024 ruling against Tropic Haze, Yuzu's publisher, which had agreed two days earlier to shut down and pay $2.4 million.

Two things set this wave apart. This time Nintendo is protecting a console still in the middle of its commercial run, the Switch 2, not a machine at the end of its life. And the method shows its limits: those 311 Suyu repositories were mostly identical copies, put back online after every takedown. github/dmca has logged Nintendo notices almost every month since February 2024, including 19 in 2026 alone. Taking down a repository takes a night; recreating it takes a minute.
