Sudachi Prod Keys — Setup by Build Date
Sudachi releases have never followed a steady schedule, so its key requirement tracks the build date rather than a version number you can look up. The practical rule is to match the keys release and the build to the same period.
Where Sudachi looks for keys
Where Sudachi reads prod keys
- Windows
%APPDATA%/sudachi/keys/ - Linux
~/.local/share/sudachi/keys/ - Android
Internal/Sudachi/keys/
Also Yuzu-lineage. Key requirement depends on the build date; very old builds pair with the keys release from the same month.
Matching keys to the build
- Check the date of your Sudachi build in its about screen.
- Take the keys release published closest to that date from the version history.
- If games still fail, take the newest release instead — newer keys do not break older builds, they simply do not extend them.
When it crashes instead of reporting an error
A Sudachi crash on launch, rather than a keys message, is usually a mismatched pair: new firmware with old keys, or the reverse. Reinstall both from the same generation before changing emulators.
Frequently asked questions

The release from the same period as your build, or the newest release if you are unsure.<br />
Where is the Sudachi keys folder?
%APPDATA%/sudachi/keys/ on Windows, ~/.local/share/sudachi/keys/ on Linux, app storage on Android.<br />
Why does Sudachi crash after updating keys?
Usually keys and firmware are from different generations. Install both from the same release window.<br />
