system state is not the same as a save file. System state is the cpu registers, the process' entire memory space (because you don't know what the game might do at any point) gpu context, etc.

edit: example: the save file for older games was measured in bytes. System state is much larger han that. It contains everything not just what the developer decided to allow you to save.
