Nintendo has initiated a broad DMCA takedown campaign targeting open-source firmware repositories on GitHub. The company's action has resulted in the removal of 144 tools associated with modchips for the Nintendo Switch console.

The affected firmware includes code for devices such as Picofly, HWFLY, and SX Core. These chips are used to bypass the console's boot sequence and technological protection measures, which Nintendo argues facilitates the use of unauthorized game copies.

The legal justification for this action relies on the DMCA, with Nintendo citing previous criminal proceedings by the US Department of Justice against Team-Xecuter. The company claims the distribution of this firmware constitutes unlawful trafficking in circumvention technology.

While the takedown prevents future firmware updates, flashing, and new installations, it does not affect consoles that already have modchips installed. The move effectively limits the ability of users to modify their hardware for homebrew, emulation, or overclocking.
