Save/Load system how does it work?

[Andyoyo]

Do the save/load systems save variables to the computer itself? Can a code be made so that it is only usable for the one computer to load a hero, the same code won't load for other players?

They often convert units, items, gold... into code, and when you load, they decode it creating a completely new unit with the same stats, items, level, and all that you saved it with.
