The basic steps to edit saved games as follows:
- Export the saved game from the game's platform.
- Load the file into DISE.
- Edit the file using DISE.
- Save the file using DISE.
- Import the file back to the game's platform.
If you intend to edit saves for PC then you should already have access to the files on the same computer that is running DISE. This makes PC the platform that is easiest to work with. Other platforms involve more steps detailed on pages for those platforms.
