How to add games to Lichii

Once keys and firmware are in, Lichii needs to know where your game dumps live. This covers the games folder, the file formats Lichii reads, and how updates and DLC fit in, because the wrong game version is a top reason a title won't boot.

Checked 6 Nov 2026

Use dumps of games you own. This site doesn't link game files or explain where to find them, and neither does the Lichii project.

Add a games folder

  1. Put your dumps in one folderFor example D:\Switch2\Games. Subfolders are fine.
  2. Double-click the empty game listOr use the add-folder option in the File menu, and choose that folder.
  3. Wait for the scanTitles appear with names and icons once keys are installed. Eglantine's recent builds made scanning much faster, and Lichii inherits that.

Formats Lichii reads

  • XCI: a cartridge image. Lichii reads Switch 2 XCI metadata to choose the right guest clock (fixed in build 83).
  • NSP: digital titles, updates and DLC, the same as on Switch 1 emulators.
  • NUP: a newer container that bundles the game, its update and DLC in one file. The project added NUP support so a single file brings everything, and it shows the NUP's update version in the game list.
  • Unpacked folders (ExeFS + RomFS): early Switch 2 builds booted games this way, and the game list can scan unpacked ExeFS folders automatically.

Eglantine build 212 fixed a NUP problem worth knowing about: a NUP whose base ExeFS was empty made Switch 2 titles boot with the Switch 1 memory layout and freeze at 0 FPS. Mario Kart World 1.8.0 now picks the 12 GiB layout from the update and reaches the title screen. If an older build gets stuck at 0 FPS, update first.

Updates and DLC

If your update or DLC is a separate file, install it with File → Install Files to NAND, select the files and confirm. The game's Add-Ons column then lists what's installed. To switch an update off (handy when a new game version breaks emulation), right-click the game → Configure Game and untick it. Disabled entries show a [D].

A NUP or a merged file that already contains the update doesn't need this step.

Why the game version matters

Fixes in Lichii are often tied to a specific game version. The Ocarina of Time Dynamic FPS patch only applies to the supported game build, and the Mario Kart World fixes are described against version 1.8.0. If a game behaves differently from what the compatibility list says, compare your version first.
