Nintendo Issues DMCA Takedowns for 400+ Switch Emulator Repositories on GitHub
Key points
- Nintendo issued seven DMCA takedowns on GitHub.
- 401 Switch emulator repositories were removed.
- Takedowns targeted Suyu, Yuzu, and Skyline emulators.
- Nintendo cited circumvention of anti-piracy measures.
Widespread Takedowns on GitHub
Nintendo initiated a coordinated campaign of DMCA takedowns on GitHub, targeting repositories related to Nintendo Switch emulators. This action led to the removal of 401 repositories, primarily due to GitHub's policy of removing entire networks of forks if a parent repository has over 100 forks and receives a valid DMCA notice. Seven distinct strikes were filed by Nintendo on the same day.
Targeted Emulators and Their Forks
The primary target was the Suyu emulator, a fork of the previously shut down Yuzu emulator, which had 311 associated repositories removed. Other affected projects included the defunct Android-based Skyline emulator with 29 forks, Yuzu Android with 8 forks, NicholasArvani's Yuzu fork with 14 repositories, an early access Yuzu build with 21 forks, and MonoNX with 17 forks, along with the main Yuzu emulator parent repository.
Nintendo's Stated Reasoning
Nintendo's justification for the takedowns centers on piracy concerns. The company stated that these emulators "illegally circumvent Nintendo's TPM in order to run illegal copies of Nintendo Switch games." Nintendo argues that emulators rely on 'prod.keys' files to bypass the cryptographic key verification required for Switch games, thereby facilitating the use of pirated software.
Impact on Emulator Development
The takedowns significantly impact the public availability of Switch emulator source code and development on GitHub. While some projects like Skyline were already defunct, the removal of active projects and their forks demonstrates Nintendo's continued efforts to combat emulation it deems illegal. The removed repositories now link to the DMCA notices, and their forks may display 404 errors.
