Ryujinx Prod Keys and Firmware: System Folder and Install

Last checked 9 November 2026 against Lichii build 117

Ryujinx reads prod.keys and title.keys from %APPDATA%\Ryujinx\system on Windows and ~/.config/Ryujinx/system on Linux. The original project went offline in October 2024; the community continuation, Ryubing, keeps the same folders.

How do you install keys and firmware in Ryujinx?

Copy prod.keys and title.keys into the system folder, or use File > Open Ryujinx Folder to find it.
Open Tools > Install Firmware > Install a firmware from XCI or ZIP.
Select the firmware ZIP and confirm.

Does Ryujinx run Switch 2 games?

No. Ryujinx and Ryubing emulate the original Switch. For Switch 2 games use Lichii with Switch 2 title keys and prod keys.

Can you reuse Ryujinx keys in Lichii?

Yes for Switch 1 games: copy prod.keys from the Ryujinx system folder into Lichii’s keys folder. Switch 2 games still need Switch 2 keys.
