In this confusing yet astounding video, one gamer beats all four Super Mario Brothers games at the same time. How is this possible? Well – I’m going to let Wired explain it:

The trick is that this is a tool-assisted speedrun — using emulators, save states, and running the games at a very slow pace, he was able to individually tweak and nudge each movement of the four Marios so that they would stay a hair’s breadth from danger. It’s still a remarkably impressive achievement when you consider the painstaking care that such a meticulous feat would require.

May I call on the nerds again to dissect that statement? Anyways, as Wired points out, sitting through the entire 13-minute eloquent trainwreck that is this video may not be such an efficient use of your time, so you might want to jump to around the 10-minute mark where he defeats three of the final bosses simultaneously. Still not sure if this beats the dude that achieved a 999-hit combo in Marvel vs. Capcom, though!
