Lichii runs original Nintendo Switch games as well as Switch 2 games, and original Switch games use Switch 1 keys and firmware. Lichii inherits that support from Eden, which emulates only the original Switch.
Do Switch 1 games need Switch 1 keys in Lichii?
Yes. An original Switch game is encrypted with Switch 1 key generations, so its keys must be in prod.keys. If you already used Eden, Lichii reads the same keys folder and finds them.
Can Switch 2 firmware run Switch 1 games?
On real hardware, yes: the Switch 2 runs most Switch 1 games through its own backward compatibility. In an emulator, the result depends on Lichii’s build; when a Switch 1 game fails on Switch 2 firmware, Eden with Switch 1 firmware is the fallback.
How do you keep both setups apart?
- Back up
%APPDATA%\edenbefore testing a new Lichii build. - Use a portable Lichii install (a
userfolder next to the program) for Switch 2 files. - Keep Eden’s normal data folder for Switch 1 files.
