Another one for Link's Awakening. One quest you are supposed to escort some girl from one village to another so she can do something. But there is a glitch where you could hit start or select (forget which) while change screens and warp to a matching place on the next screen, i.e. leave the screen in the upper right hit start at the right time and you end up on the next screen in the same upper right location. Using this you could bypass the screen where the girl would leave you and have her travel around with you some more. But you couldn't enter dungeons or anything with her. And later on there is a spot where you are supposed to meet her again and if you still had her following you, you could freeze the game.
