About a year ago, YouTuber SethBling exploited a bizarre glitch in Super Mario World in order to "beat" the game by triggering the credits just six minutes into gameplay. A series of precisely executed actions allowed him to rewrite the game's code as he played, making it possible to trigger the credits. SethBling has returned with a new video, this time taking the code rewriting idea to a whole new level. Through a similar glitch, he found a way to inject the code for Flappy Bird into Super Mario World, creating the popular mobile game inside of the classic SNES game.
