Watch someone use glitches to inject Flappy Bird into Super Mario World

Super Mario World is one of the most beloved games ever made, and that has led to fans breaking the game open in order to figure out how they can change it and manipulate it. And now someone has taken this to an extreme new high.

YouTube personality SethBling has uploaded a new video where he goes through a process to inject 2014 sensation Flappy Bird into Super Mario World by hand. Using a number of well-known glitches and by positioning Mario at certain coordinates in one Super Mario World’s levels, SethBling was able to write several lines of code into the game’s memory. This is something we’ve seen other people do before using the tool-assisted robot (TASbot), but that enables players to predetermine a number of controller inputs that the TASbot will then feed to the Super Nintendo. In this case, SethBling actually hand-controlled every piece of this process — he pointed out that this is likely the first time anyone has ever coded another game inside of Super Mario World without computer-controlled assistance.
