Lichii: Lichii, a Switch 2 emulator, and its 30,000-commit development history

It is an experimental open-source emulator for running Nintendo Switch 2 on PC. Written in C++, it is developed as a fork based on the code of existing projects such as Eglantine, Eden, yuzu, and Sudachi. It is an independent fork and not an official Nintendo project, currently in an active development stage with 30,243 commits.

Save data and configuration files from existing Eden or Eglantine users are preserved as is. Data directories and configuration keys are not moved or deleted, allowing users to continue using it directly from their previous environment. However, due to the nature of the experimental build, game compatibility and performance may vary depending on the hardware and driver environment, and it is noted that rendering errors or crashes may occur.

It supports major desktop platforms such as Windows, Linux, and macOS. On Windows, it is used by running lichii.exe. The GUI build target name remains yuzu, but the output filename is unified as Lichii. Game files or firmware are not included, and users must only use system files and games that they have legally obtained.

When reporting bugs, users must provide the exact build version, game version, CPU/GPU specifications, driver version, and reproduction steps. It is recommended to attach logs and screenshots after checking for personal information. The project is free, and cryptocurrency donations are accepted to cover the costs of AI tools used in development and build machines, but this is optional.
