Lichii is the experimental, open-source emulator that runs Nintendo Switch 2 games once Switch 2 prod keys and firmware are installed. Its newest release is build 117 (7 November 2026); it works with prod keys and firmware 22.5.0, reads both from the eden data folder, and descends from Eglantine, Eden, yuzu and Sudachi.
What does Lichii need to run Switch 2 games?
| File | What it does | Where to get it |
|---|---|---|
| prod.keys | Decrypts every game, update and firmware file | Switch 2 prod keys |
| Firmware | Supplies system fonts, applets and modules | Switch 2 firmware |
| title.keys | Decrypts dumps that ship without a ticket | Switch 2 prod keys and title keys |
| Game dump | The game itself, as an XCI or NSP file | Your own console and cartridges |
Which platforms does Lichii run on?
Lichii runs on Windows as lichii.exe and on other desktop platforms as lichii. Linux and Steam Deck use an AppImage. macOS support in the Eden code base is experimental and depends on MoltenVK.
Where does Lichii keep its data?
Lichii keeps the Eden and Eglantine data directories, so existing keys, firmware, saves and shader caches carry over. On Windows the data lives in %APPDATA%\eden; on Linux it lives in ~/.local/share/eden.
