Thats a good idea.... But what if the other person was the one who activates the code...
Like you go to your friends town with the cheat on and they can press certain buttons to make it so you can do that cheat. And press certain buttons to make it so you can't do that cheat. Also it would help if there was a cheat that allowed you to see yourself and the visitors by dividing the upper screen in four units, or is that even possible???
