Nintendo files DMCA notices against 217 Switch repositories on GitHub

What Nintendo asked GitHub to remove

Nintendo sent four copyright takedown notices to GitHub on 6 November 2026, targeting 217 repositories in all, according to TorrentFreak as reported by GameVicio and Voxel. The notices covered copies of the Switch emulator Yuzu and projects derived from it, and also firmware used by modchips that unlock the console.

One notice hit Citron Neo, a derivative of Yuzu, and GitHub disabled 71 repositories in a single action, GameVicio reported. Two other notices targeted copies of Yuzu itself, whose maintainers removed the code and the change history.

The largest single block was 144 repositories holding firmware for modchips such as Picofly, SX Core, SX Lite and HWFLY, including copies derived from the original project. Voxel described this as the first time Nintendo has moved against modchip firmware in this way.

Nintendo's argument

In the notice published by GitHub, Nintendo said the firmware lets Switch modchips circumvent its technical protection measures. According to the company, the files alter the console's boot sequence so that unauthorised copies of games can run.

"The firmware allows Nintendo Switch modchips to illegally circumvent Nintendo's TPMs to run illegal copies of Nintendo Switch games," the company wrote in the notice, as quoted by Voxel.

A modchip is a small chip soldered into a console to bypass its protections. The firmware is the software that chip runs.

Earlier cases

The notices refer back to Nintendo's past lawsuits against members of the Team-Xecuter group, which sold Switch unlocking tools. Voxel reported that the strike notice recalls the case of a well-known modder who sold unlocks for the console.

GitHub has not commented publicly on the removals beyond publishing the notice. It is not known whether the affected projects plan to appeal the takedowns or move the code elsewhere.
