SnowRunnerSaveMerge

Tool for SnowRunner to enable progress sync from you co-op host.

Requirements

Written in Node v 22.2.0 for Windows

Need to provide 7z.exe in the same directory as script for compression

Usage

This script will overwrite most of your save file, it's best to only use this with a save file dedicated to co-op play, with a consistent host!
Your save file must be on the same slot in game as the host!

Installation

1. Download the saveMerge.js file or clone the repo.
2. Run the script once to create template config file
3. Fill your config according to instructions inside
4. Make sure your load location and backup location exist
5. Copy 7z.exe to the repo directory

Running the script

It's best to run the script directly after ending your game session. To prevent accidental merges with old files if hosts save was uploaded more than 1 hour ago the script will not automatically download and merge it. If you're sure that the file is correct, download it manually and extract the files in you load location remote directory then run just merge operation

Host

1. Get all your vehicles inside a garage, best to retain them
2. Leave all newly acquired trucks, that the guest doesn't have, outside on the map
3. Exit the game
4. Run the script with upload operation node .\saveMerge.js upload

Guest

1. Get all your vehicles inside a garage, best to retain them
2. Exit the game
3. Run the script with download and merge operations node .\saveMerge.js download,merge additionally provide save slot if different than first
4. Restart Steam for safety. Sometimes the game behaves funny if steam is not restarted after save manipulation

Things that will be overwritten

• Map files
• Visited maps
• Watch towers
• Upgrades
• Tasks
• Contracts
• Objective states (half completed tasks etc.)
• Game settings (hard mode, recover and fuel costs etc.)
• Waypoints, not sure if it matters, but the game creates new array elements for them only on host side. You have to redo your route when joining anyway.

Things that are preserved

• Trucks (customizations, addons etc.)
• Money
• Exp

Auto save backup

1. Run the script with backup operation node .\saveMerge.js backup, save slot doesn't matter in this case. Whole save is backed up so it still might useful in single player game
2. The script will enter an endless loop that will backup you saves every set interval, default 10 minutes
3. Do not exit the script while files are copying, there is a message displayed when it's safe to kill the script
