Game package name:

From the issue template:

Game saves from the Xbox Game Pass / Microsoft Store version are needed to add support for the game.
Here's how to obtain the saves:

1. Open up the Windows Run dialog by pressing Win+R
2. Type in "%LOCALAPPDATA%\Packages" (without quotes)
3. Search for a folder name that possibly includes the name of the game or the name of the game developer or publisher. The name format should be something like "DeveloperOrPublisherName.PossibleGameName_RandomLettersAndNumbers", e.g. "BethesdaSoftworks.ProjectGold_3275kfvn8vcwc" for Starfield.

If you found a suitable folder name:
4. Copy and paste the folder name below in this text field. That's the package name for the game.
5. Open up the folder and the "SystemAppData" folder inside it.
6. Zip up the "wgs" folder.
