Lichii is an experimental, open-source Nintendo Switch and Switch 2 emulator written in C++. It builds on Eglantine, Eden, yuzu and Sudachi, preserving their contributions while developing this fork's game compatibility and renderer fixes.
This is an independent fork, not an official release of those upstream projects. Lichii is not affiliated with Nintendo.
Visit the official Lichii website to find games and compare community compatibility reports.
Download Lichii only from this repository's releases page. Lichii has no other download site: archives offered elsewhere, such as lichii.org, are not built by this project, and one has been reported to install malware (#545).
On Windows, extract the entire build archive and run lichii.exe. Only use games and system files you have legally obtained. Games, keys and firmware are not included.
The rebrand intentionally retains the existing Eden/Eglantine data directories and configuration keys. It does not move or delete saves, settings or shader caches. Back up your saves before testing experimental builds.
Compatibility and performance vary by game, hardware and driver. Rendering errors, stutters and crashes remain possible. Passing automated tests does not establish that a game renders correctly, and this project makes no universal frame-rate guarantee.
Browse community compatibility reports for results with each player's build and setup.
Desktop reporting requires a build containing PR #303 and is not available in build 88. In builds that include it, play and stop a Switch 2 game, then right-click that game and choose Submit compatibility report. Only the latest session in the current Lichii process is eligible.
Confirm the matching website catalog entry and review the editable machine, game, setup, and enabled add-on details prefilled where available. Check the public preview and give explicit consent before submitting. Nothing uploads automatically, and the native v1 reporter does not read or upload logs or files.
When reporting an issue, include:
- The exact build, game version, CPU, GPU and driver version.
- Relevant settings and steps to reproduce the problem.
- A screenshot and the log from the affected session, after checking it for personal information.
Do not upload game files, keys, firmware or private account information.
See the build guide, user documentation and coding guidelines. Some inherited documentation and internal build target names still use upstream names. The GUI build target remains yuzu; its output is lichii.exe on Windows and lichii on other desktop platforms.
Keep changes focused and distinguish code-level checks from actual gameplay testing.
