Nintendo Takes Down Switch Emulators and Mod Chip Firmware in Massive GitHub DMCA Sweep

Nintendo has issued four DMCA takedown notices to GitHub targeting the Switch emulators Yuzu and Citron Neo, as well as firmware used by mod chips. The action matters because the firmware can help modified consoles bypass Nintendo’s copy protection, and the removals may signal a renewed effort to limit Switch emulation.

GitHub removed 144 repositories containing the targeted mod chip firmware, though some copies reportedly remain elsewhere on the site. Nintendo’s notice, dated 6 November, says its technological protections restrict consoles to legitimate game files and help prevent piracy. The move follows Nintendo’s 2024 action against 8,500 Yuzu copies across 12 mirrors; the article also notes it comes days after emulators ran a PC remake of Ocarina of Time.
