Schedule I Dedicated Server and Client Launcher

Schedule I — Dedicated Server

Version 0. 2. 0 - build (40)

This is a very early Work-In-Progress project! Bugs will appear!

Backup your saves beforehand!

Run a 24/7 headless dedicated server for Schedule I, direct IP connect, and a full suite of server management tools.

Schedule I uses Steam P2P lobbies by default, meaning the host must stay online, can only have one game session per Steam account, and players must be Steam friends to join. This mod replaces that system entirely with raw UDP networking (FishNet Tugboat transport), enabling true dedicated server hosting — on your own machine, a VPS, or a home server. This allows for other players to play on your savegame without the host being online.

You can also use this to solo play but have a world running 24/7 that is constantly being played and days are being passed, allowing you to continue to let your automations run ingame.

For solo play hosting, simply host using the server launcher and connect with the client app to your localhost (127. 0. 0. 1).

Requirements

• []Schedule I Steam Installation (Steam, v0. 3. 4+)

  []MelonLoader (the Launcher can install this for you automatically)

  []Windows — for the GUI tools. The server mod DLL itself runs on any platform the game supports.

  What's Included

  S1ServerLauncher.exe - GUI tool to set up and run the dedicated server

  S1DirectConnect.exe - GUI tool for players to connect by IP

  Schedule1DedicatedServer.dll - The MelonLoader mod (deployed automatically by the tools above)

  True Dedicated Server

  The server runs fully headless. You can host from a machine with no Steam login active. The server bypasses Steam P2P entirely and listens on a configurable UDP port for direct connections.

  One-Click Server Launcher

  S1ServerLauncher.exe is a dark-themed GUI that handles the entire setup workflow:

  []Auto-detects your Schedule I installation via Steam registry

  []Installs MelonLoader automatically with a single button click (no manual setup)

  []Deploys and removes the server mod cleanly — the mod is only active when you launch through the Launcher, so your game remains vanilla otherwise

  []Live console output embedded in the app with ANSI colour support, showing MelonLoader logs in real time

  []Auto-restart on crash — the Launcher monitors the server process and relaunches it automatically if it exits unexpectedly

  [*]All server settings configurable from the GUI without editing JSON files manually
