Nintendo continues its fight against Nintendo Switch emulation. The company sent GitHub seven new copyright infringement notices, resulting in the removal of over 400 repositories (401, to be precise) containing Switch emulators from the platform.
Suyu was the most affected – one of the most prominent projects to emerge after Yuzu's development ceased. Of the 401 removed repositories, 311 contained Suyu. Also blocked were the Android emulator Skyline, the C# MonoNX, and numerous forks of other projects based on Yuzu.
This is far from Nintendo's first such action. In May 2024, the company, with a single request, achieved the removal of 8,535 Yuzu-related repositories from GitHub. In February 2026, Nintendo again appealed to the platform, demanding the removal of the remaining Yuzu repositories and at least 12 other Switch emulators.
In the new notices, Nintendo claims that Switch emulators are primarily intended for running console games and illegally circumvent technological protection measures. According to the company, emulators use Nintendo's cryptographic keys (prod.keys) to decrypt game copies and ROM files.
Nintendo believes that the distribution of such emulators is illegal. The pages of the removed repositories now display a blocking notice and a link to Nintendo's corresponding demand.
Legal pressure on emulator developers began particularly actively after Nintendo's lawsuit against Tropic Haze – the creators of Yuzu – in 2024. The company claimed that copies of The Legend of Zelda: Tears of the Kingdom had been downloaded over a million times even before its official release, and Yuzu allegedly facilitated piracy "on a colossal scale."
Ultimately, the parties reached an agreement just weeks after the lawsuit was filed. Tropic Haze ceased work on Yuzu and agreed to pay Nintendo $2.4 million in compensation.
