Talk:Inaccessible Rooms/@comment-27505372-20151230075832

What is the specific set of things I need to do to access any of these rooms? I have no 'save0' file, and I editing just the undertale.ini doesn't do anything. It'd be great if someone could explain how to use cheat engine or anything to go to these rooms, because I love to uncover secrets/easter eggs in games.
