Nintendo has successfully taken down over 8,500 repositories related to the Yuzu emulator from GitHub. This move comes after the emulator’s developers settled with Nintendo for $2.4 million, discontinuing further development and transferring the codebase to the gaming giant.

The aftermath of this legal action reveals a complex landscape of emulation, copyright concerns, and community resilience.

The takedown, as detailed in a statement on GitHub, stems from Nintendo’s Digital Millennium Copyright Act (DMCA) complaint on April 29. The company asserts that its use of cryptographic keys to decrypt and play Switch games violates anti-circumvention measures under the DMCA.

“Because the reported network that contained the allegedly infringing content was larger than one hundred (100) repositories, and the submitter alleged that all or most of the forks were infringing to the same extent as the parent repository, GitHub processed the takedown notice against the entire network of 8,535 repositories, inclusive of the parent repository,” read the statement.

While Yuzu did not include console hardware keys in its code, users were required to provide prod.keys themselves, raising legal questions about its compliance with copyright law.

Despite the takedown affecting thousands of repositories, the Yuzu code remains accessible through various channels outside GitHub. Many users had already forked the code to their repositories or backed it up on alternative hosting platforms, making it resilient to Nintendo’s takedown efforts, reports PC Gamer.

Additionally, Yuzu’s successor, Sudachi, has adapted its approach by removing title.keys-related code, shifting the burden of providing keys to users for each game.

Last month, GitLab took action against Suyu, a fork of Yuzu.

The swift settlement between Yuzu developers and Nintendo, along with the absence of courtroom battles over emulation and the DMCA, leaves legal uncertainties regarding the interpretation of anti-circumvention laws in the context of emulator development.

While Nintendo’s actions may deter some developers, other projects like Ryujinx continue to operate, suggesting a nuanced legal landscape where certain emulators may navigate legal challenges more effectively.

The emulation community’s response to Nintendo’s takedown reflects a mixture of resilience and adaption. The community made several forks and backed the code across other hosting platforms.

Last month, due to a takedown request by Nintendo, Garry’s Mod removed all materials related to the gaming giant. In March 2024, GitLab took action against the Nintendo Switch emulator Suyu, a fork of Yuzu, after it received a DMCA takedown request.
