Yuzu Prod Keys and Firmware: Old Folder and Moving to Lichii

Last checked 9 November 2026 against Lichii build 117

Yuzu read prod.keys from %APPDATA%\yuzu\keys on Windows and ~/.local/share/yuzu/keys on Linux. Yuzu was discontinued on 4 March 2024 after its developers settled Nintendo’s lawsuit, so it receives no updates.

Where are Yuzu’s keys, firmware and saves?

Data	Windows path
Keys	`%APPDATA%\yuzu\keys`
Firmware	`%APPDATA%\yuzu\nand\system\Contents\registered`
Saves	`%APPDATA%\yuzu\nand\user\save`

How do you move from Yuzu to Lichii?

Install Lichii from the official GitHub releases page.
Copy prod.keys and title.keys from Yuzu’s keys folder to %APPDATA%\eden\keys.
Copy Yuzu’s nand\user\save folder to the same place under %APPDATA%\eden.
Reinstall firmware with Tools > Install Firmware rather than copying it.

Do Yuzu keys work for Switch 2 games?

No. Yuzu keys are Switch 1 keys. Switch 2 games need Switch 2 title keys and prod keys.
