Setting up Lichii takes 6 steps: download the official build, extract it, install prod keys, install firmware, add your games folder and configure a controller. Use prod keys and firmware 22.5.0, the newest matching pair.
What do you need before you start?
- A 64-bit Windows or Linux PC, or a Steam Deck.
- On Windows, the latest Microsoft Visual C++ Redistributable; Lichii does not start without it.
- Prod keys and title keys and Lichii firmware download.
- Game dumps from your own cartridges or console, as XCI or NSP files.
Step 1: Download the official Lichii build
Download the latest build (117) from the Lichii GitHub releases page. The project has no other download site; the Lichii emulator download page explains how to tell real builds from copies.
Step 2: Extract the archive and run Lichii
Extract the full archive to a folder you control. For a portable install, create a folder named user next to the program. Run lichii.exe; if Windows SmartScreen warns, choose More info, then Run anyway.
Step 3: Install prod.keys
Close the missing-keys dialog with OK, open Tools > Install Decryption Keys and select prod.keys.
Step 4: Install firmware
Open Tools > Install Firmware and choose From ZIP or From Folder. Install firmware 22.5.0, the newest version with matching prod.keys.
Step 5: Add your games folder
Double-click the empty game list and select the folder that holds your XCI and NSP files. Titles and icons appear when the keys decrypt them.
Step 6: Configure a controller
Open Emulation > Configure > Input, map your controller and select OK. Double-click a game to launch it.
How do you set up Lichii on Steam Deck?
Switch the Steam Deck to Desktop Mode, download the Lichii AppImage, and run it. Then follow steps 3 to 6; the keys folder is ~/.local/share/eden/keys.
