RO3Emu is a server emulator for Ragnarok Online 3's PC client, written in C# with .NET 10. It implements core MMORPG systems including world and combat mechanics, parties and economies, guilds, dungeons, and territory wars. The server uses SQLite for persistence and coordinates gameplay through a single game loop that handles protocol messages from the HTTP SDK and game gates.
Designed for players who want to host private servers and developers studying MMORPG architecture. The project includes protocol research, gameplay system implementations, and server tools. Documentation cites client evidence where available and marks reconstructed mechanics. Built with Claude-code and distributed under GNU GPL v3.0.
