🧩 Transfer Save Files from Demo to Full Game — Ball x Pit (Steam Deck & Linux)

Want to carry over your progress from the Ball x Pit demo to the full game? This guide walks you through transferring save files using Proton’s compatibility folders. Works on both Steam Deck (in Desktop Mode) and Linux.

Requirements:

• Steam Deck in Desktop Mode
  
• Linux system with Steam installed
  
• Both demo and full game installed
  
• Hidden files must be visible (Ctrl + H in most file managers)

Step-by-Step Instructions:

1. Enable Hidden Files
Open your file manager and press:

Ctrl + H

This reveals hidden folders like `.local`.

2. Navigate to Proton Compatibility Data
Go to:

/home/deck/.local/share/Steam/steamapps/compatdata/

On Linux, replace "deck" with your actual username.

3. Find the Demo and Full Game Folders
Inside `compatdata`, use the search bar to look for:

ball

This should show two folders:

• One for the Demo
  
• One for the Full Game

Confirm which is which by checking inside each folder for recognizable save paths like:

pfx/drive_c/users/steamuser/Saved Games/

4. Transfer Save Files

• Open the Demo folder and locate the save files.
  
• Copy all relevant files.
  
• Paste them into the same location inside the Full Game folder.
  
• Overwrite any existing files when prompted.

5. Launch the Full Game
Start Ball x Pit from Steam. Your demo progress should now be available in the full version.

Tips:

• Always back up your original save files before overwriting.
  
• If you're unsure which folder is which, check the `appmanifest_*.acf` files in `/steamapps` — they contain game names and IDs.
  
• This method works because Proton isolates each game in its own Wine prefix under `compatdata`.
