Switch 2 firmware is the system software the Lichii emulator installs next to its prod keys: the system modules, fonts and applets that games call while they run. The newest download is firmware 23.0.1; the newest version with matching prod keys is 22.5.0, so install 22.5.0 until prod keys 23.0.1 are out. Lichii installs either one from its ZIP through Tools > Install Firmware.

Why does Lichii need Switch 2 firmware?
Lichii needs firmware because Switch 2 games load shared system files that the emulator does not recreate: the system fonts, the Mii and keyboard applets, and the system archives that hold error messages and certificates. Without firmware, many games stop at a black screen or crash on the first menu.
Which firmware version should you install?
Install the newest firmware that your prod keys support: today that is firmware 22.5.0 with prod.keys v22.5.0. Firmware 23.0.1 needs prod keys 23.0.1 or later. The Switch 2 firmware versions list shows every release and its date, and the compatibility chart pairs each one with a key set.
How do you install Switch 2 firmware in Lichii?
- Install prod.keys first; Lichii cannot read firmware without keys.
- Open Tools > Install Firmware.
- Choose From ZIP for the downloaded archive, or From Folder if you extracted it.
- Wait for the install to finish, then restart Lichii.
Is Switch 2 firmware a ZIP or a folder?
Switch 2 firmware is distributed as a ZIP archive of NCA files, one NCA per system title. Lichii accepts the ZIP directly or the extracted folder of NCAs; do not rename or nest the NCA files.
