After installation, restart Yuzu. Go to to verify the firmware version matches what you downloaded.
Downloading copyrighted firmware or keys from the internet is illegal in most jurisdictions. The only legally compliant method is to extract them from a Nintendo Switch that you personally own.
The only legally compliant way to acquire Nintendo Switch firmware and keys for Yuzu is to dump them directly from your own, personally owned Nintendo Switch console. This requires a launch-model Switch or a modded console capable of running custom firmware (CFW) like Atmosphere. Prerequisites for Dumping Firmware A hackable or modded Nintendo Switch console. An SD card formatted to FAT32 or exFAT.

While the Yuzu firmware GitHub repository has been instrumental in driving development, there are challenges and limitations to consider:
Thus, acquiring the proper firmware is for a functional emulation experience. This is where GitHub enters the picture.
By leveraging GitHub, the Yuzu team has been able to: After installation, restart Yuzu
: The original repository was deleted, but "frozen" mirrors and forks (like yuzu-mirror ) still host the final builds (Mainline 1734 / Early Access 4176). 🛠️ Firmware & Setup on GitHub
Because these files are copyrighted by Nintendo, they cannot be officially hosted by the Yuzu team. Instead, the community hosts them on GitHub repositories.
If any of these subfolders are missing, create them exactly as written in lowercase. The only legally compliant method is to extract

Restart the emulator. If the installation was successful, the emulator will no longer prompt you with a "Missing Keys" error on startup. Furthermore, checking the system settings or logs will display the specific firmware version you installed (e.g., Firmware 18.0.0). Best Practices and Safety Warnings
Emulation technology itself is legal. But the way you obtain system firmware determines whether you are in the clear or in Nintendo’s legal crosshairs. Stay informed, respect intellectual property, and always support game developers by buying the games you love.
The keyword typically indicates that a user is looking for a GitHub repository containing a pre-packaged firmware archive. Several repositories have appeared and disappeared over time due to DMCA takedown requests from Nintendo. As of 2026, you will find that many such repos are already deleted, forked, hidden, or moved to alternative Git hosts like GitLab or self-hosted Gitea instances.
Because the official Yuzu website and its GitHub organization were taken down, independent developers used GitHub to archive the final builds of the emulator. Concurrently, some users host "firmware repositories" on GitHub containing pre-dumped Switch system files.
