Nintendo issued four DMCA takedown notices to GitHub targeting the Switch emulators Yuzu and Citron Neo, as well as firmware used with mod chips. The largest impact fell on mod-chip software: 144 repositories were removed. Nintendo says Switch consoles use technological protection measures to run legitimate game files, and that bypassing those protections enables piracy and unauthorized copying or play. Mod chips such as Picofly can be soldered onto a Switch’s mainboard and flashed with firmware that circumvents those safeguards.
The removals do not appear to have eliminated all copies of the firmware, which TorrentFreak reported remained available elsewhere on GitHub. The action also recalls Nintendo’s 2024 effort to remove roughly 8,500 Yuzu copies by targeting 12 mirrors. Its timing, shortly after emulators ran a PC remake of The Legend of Zelda: Ocarina of Time, suggests a renewed focus on emulation and circumvention tools. The sweep highlights Nintendo’s continuing legal pressure on software and hardware that can enable unauthorized use of its games, while the material’s persistence online shows the limits of takedowns in preventing redistribution.
