Are you referring to a save game editor? If so, I don't think you're in the right forum for that, as it isn't really modding, but to answer your question, they don't exist (yet). There are cheat engine trainers and the like, but there aren't any save game editors.
Edit: Looks like Gel214th beat me to it.
