Puzzle 490: Quad-Wrangle 20

After you're done wrangling these quadrangles (or before, if you wish), check out this quad-run of the first four Super Mario Bros. games (including the game known as Super Mario Bros. 2 in Japan and The Lost Levels elsewhere). This quad-run aims to beat all four games using the exact same series of button presses. As a tool-assisted run, this series of button presses was not achieved by a person playing the game in real time as the games were meant to be played, but through the use of emulators with savestates, slowdown, frame advance, and other tools; see this topic for more information before crying "hax!" or "cheater!".
