Why Mu Linux 97K?

🐧

Native Linux

Ported from Windows to Linux with epoll and MySQL 8.4 instead of MSSQL. No Wine, no VM, on amd64 and ARM64.

🐳

Docker ready

Four Docker Hub images: server, web, editor and MySQL. One docker compose up and it's running. Pterodactyl eggs included.

🎮

Windows and Linux client

Client rebuilt from the 0.97k source, with everything Main.dll did built in. No DLL, no InfoEncoder.

🖥️

Full web panel

Admin panel with graphical editors for items, monsters, shops, spawns, drops, quests, rates and more.

🧩

Server-side customs

Items up to index 511 per section, sets, wings, effects, pets and monsters. The server sends the definitions; the client only carries the models.

Game client

🖥️ Windows and Linux

The client is a C++ port of the original 0.97k main.exe, with everything Main.dll did built in. Your server address is compiled in: each server builds and distributes its own client.

  1. 1

    Set your server address in src/Config/ServerConfig.h

    IP or domain, ports and server identity

  2. 2

    Build for Windows · Linux

    with Visual Studio, CMake or GitHub Actions from a fork

  3. 3

    Distribute to your players

    the client folder on Windows or the Linux package

The DLL client, InfoEncoder and ClientInfo.bmd are deprecated.

Full client guide →

Custom items, wings, effects, pets and monsters are defined by the server: the client only needs the models.
