Super Mario Bros: The Lost Levels (or Super Mario Bros. 2, if you prefer) is brutally difficult. For most of us, just completing the game is out of the question, much less completing it in under an hour. We're proud to say that we completed it once, but it took a week -- and two people.
But YouTube user sprocket2005 managed to complete the All-Stars version of this ridiculous game, or at least through 8-4, in 8 minutes and 35 seconds. Even if it is a tool-assisted speedrun, this is an amazing achievement. More importantly, it makes for an impressive video -- which you can see after the break. It might make you want to download the Famicom Lost Levels on the Virtual Console and try it for yourself.
