Nintendo Files DMCA Notices Targeting GitHub Switch Emulator Forks and Build Assets

Nintendo submitted a set of Digital Millennium Copyright Act notices to GitHub on February 25, 2026, specifically aimed at multiple repositories that host or mirror Nintendo Switch emulator source code, forks, and related build assets. The filings named several emulator projects and forks as the basis for removal requests.

The notices singled out source code copies, community forks, and compiled build assets used to assemble or distribute Switch emulators. According to the filings, the targeted materials included both original emulator repositories and mirrored forks that reproduced the same source and build files, leading to takedown actions against those repository entries on GitHub.

The February 25 filings resulted in takedown bans affecting the identified repositories and mirrored assets. Those takedowns removed or limited access to the flagged repositories and associated build packages on the Git hosting platform, disrupting the availability of the specific emulator forks and their build artifacts referenced in the notices.

Nintendo’s action focused on enforcement against code and build assets tied to Nintendo Switch emulation rather than user posts or forum discussions. By naming emulator source code, forks, and build assets in the DMCA submissions, the company targeted the projects that enable compilation and distribution of software intended to reproduce Switch functionality.

The filings submitted on February 25, 2026, leave the future status of the affected repositories dependent on the takedown process already set in motion. GitHub-hosted code owners and those maintaining mirrored forks now face the immediate consequences of the notices, with the flagged repositories unavailable or restricted following the DMCA enforcement on the platform.
