DSMOO – Dimenzio's Super Mario Odyssey Online Server

DSMOO is a standalone server implementation for the Super Mario Odyssey Online Mod with server-side plugin support.

The DSMOO server was built from scratch with a focus on modularity, plugin extensibility, and a cleaner, maintainable codebase.
It includes all features of the original SMOO server while introducing many new improvements and capabilities.

Usage

Commands

• Use the help command to list all available commands.
• Wrap arguments containing spaces in quotes, e.g., sendall "Awesome Stage" will teleport players to the full stage name instead of splitting it.
• Use the arrow keys to navigate through previous commands.

Configs

• All configuration files are located in the configs folder next to your server executable.
• After editing a JSON file, use config load to reload the changes.

Plugins

• Install plugins by placing .dll files in the plugins folder.
• All .dll files, including those in subdirectories, will be loaded automatically.

Mods

• Place additional files in the mods folder to add support for custom stages or kingdoms.
• To force a stage that is unknown to the server, append ! to the stage name, e.g., sendall "Awesome Stage!".
