## Requirements & limits

- **Prerequisites:** The Little Fighter 2 v2.0a installer is needed for original game data; Flatpak downloads it during installation, while other platforms prompt users to provide a copy.
- **Prerequisites:** Building requires CMake 3.25+, Ninja, a C++23 compiler, and the development libraries listed in BUILDING.md.
- **Limits:** Gameplay compatibility is still under development; original LF2 network compatibility is unsupported.
- **License:** MIT license covers OpenLF2 code, scripts and documentation, not the original game assets.
