Nintendo has sent four DMCA takedown notices to GitHub targeting the Yuzu and Citron Neo Switch emulators and mod chip firmware. The notices cover firmware for mod chips such as Picofly, which can be soldered onto a Switch mainboard to circumvent Nintendo's copy protection; 144 repositories carrying that firmware were removed and replaced with a takedown notice. Nintendo's November 6 notice argued that the Switch's technological protection measures stop pirated games and unauthorised copying. IGN reported that the firmware still appears to be hosted elsewhere on GitHub, according to TorrentFreak. IGN suggested Nintendo may not be finished, noting that in 2024 a takedown targeting 12 mirrors of Yuzu removed 8,500 copies, and that the notices came days after emulators could run the Ocarina of Time remake on PC. IGN also described a wider crackdown on AI-assisted game copies, citing Rockstar's removal of a browser version of GTA 5 and Bethesda's takedown of an AI-generated Fallout New York game, and framed the rise of AI as changing emulation. Those points are IGN's own analysis rather than established findings.
