"Big N" keeps pushing back against Switch emulators. The company sent seven additional DMCA takedown notices to GitHub, and the immediate outcome was the removal of 401 emulator-related repositories from the site. The biggest casualty was Suyu — a well-known successor to Yuzu; 311 of the removed repos hosted that project. Other targets included the Android emulator Skyline, MonoNX (written in C Sharp), and a raft of Yuzu-based forks.
Open any of the affected repositories and GitHub now shows a takedown banner with the text of Nintendo's notice. The company argues these projects are built to run Switch titles and to evade the console’s technical protection measures.
Nintendo also points to the use of unauthorized cryptographic keys (e.g., prod.keys) to decrypt game files. Its stance: distributing tools that rely on such keys or are primarily intended to bypass technical safeguards runs afoul of the DMCA.
This sweep isn’t unique. Back in May 2024, Nintendo secured the removal of 8,535 repositories that contained copies of Yuzu via a single notice. Then in February 2026 the company again pressed GitHub, asking for the remaining Yuzu versions and at least a dozen more Switch emulators to be taken down.
There’s also been direct litigation. Nintendo sued the Yuzu developers — accusing the Tropic Haze team, in 2024, of enabling piracy of The Legend of Zelda: Tears of the Kingdom, which the company says was illegally downloaded more than a million times before launch. The dispute ended within weeks when Tropic Haze agreed to pay $2.4 million.
