🎮 XGP‑Save‑Tools 🎮

A .NET version of XGP-save-extractor rebuilt with new features, allows you to extract or replace Xbox Game Pass (PC) save files, enabling easy transfer of game saves between Xbox Game Pass and Steam/Epic versions (on supported games).

This version includes:

• Generic handler (allows extraction of saves from ANY game as long as it does not require any extra encryption)
• Replace mode (helps you to transfer saves from steam/epic into Xbox Game Pass)
• Custom directories
• Better menu navigation

Requirements

• .NET 6 runtime
• Windows 10/11 (UWP package layout located at %LOCALAPPDATA%\Packages)

---

Extensibility

Most games will work using the generic handler.

Obs: If a game is not registered on the games.json, it's extracted files names will have no extension suffixes.

Some games require unique handlers, those have to be implemented.

Configure supported games via a strongly-typed games.json file:

{
  "games": [
    {
      "name": "Atomic Heart",
      "package": "FocusHomeInteractiveSA.579645D26CFD_4hny5m903y3g0",
      "handler": "1c1f",
      "handler_args": { "suffix": ".sav" }
    },
    {
      "name": "Starfield",
      "package": "BethesdaSoftworks.Starfield_8wekyb3d8bbwe",
      "handler": "starfield"
    }
    // Add or tweak game entries here...
  ]
}

• package: Folder path within %LOCALAPPDATA%\Packages
• handler: Built‑in save format handlers (generic,1c1f, 1cnf, starfield, etc.)
• handler_args: Handler-specific configurations such as file extension ({ "suffix": ".sav" })

If a game requires a new format handler, you must implement the ISaveHandler interface.

How to Use

Extract Saves

1. Select your game from the available list, or enter a path to your wgs directory.
2. Select your user container ID.
3. Choose Extract Files.
4. The tool will display each OutputName and generate a ZIP file in the root directory.

Replace a Save Entry

1. Select Replace Entry.
2. Choose the save slot to overwrite.
3. Provide the file path to your new save file.
4. Keep replacing slots until you're done, then select Finish
5. The tool automatically backs up the container before overwriting every selected file.

Caution: Not all listed entries are save slots, some files contain crucial general information and can break the game if replaced.
