Migrating save files from the DEMO version to the full game of DELTARUNE on Linux can be a bit tricky, but this guide will help you do it smoothly. By following these steps, you can ensure that your progress in the DEMO version carries over to the full game without any issues. Let’s get started.
Short answer
Run this command in the system terminal (idk how this works on the steam deck but you probably have to switch to desktop mode to do this):
cp ~/.steam/steam/steamapps/compatdata/1690940/pfx/drive_c/users/steamuser/AppData/Local/DELTARUNE/* ~/.steam/steam/steamapps/compatdata/1671210/pfx/drive_c/users/steamuser/AppData/Local/DELTARUNE/
this will probably overwrite your savefiles in the full game, if you have any.
Why?
Steam’s Proton makes a separate Windows folder for every game you launch, so the games cannot mess with your files accidentally. Deltarune does nothing to circumvent this, which is fair but also means that you have to manually move the saves before the game sees them. The command above does exactly that.
Additional notes
This guide assumes that:
- you have saves in the demo
- you ran both the demo and the full game at least once on your device
- your steam installation is in the ~/.steam folder (or that there’s a symlink to the real folder there)
