Ever wonder how told NES games work? Well, Youtubers The Slow Mo Guys offers a look at the iconic Super Marios Bros. game, slowed down to 380,000 frames a second, via an ultra high-speed camera.

At 1600 FPS, we see that the game’s image is a line of pixels that scrolls from top to bottom at such a speed that our brains put together a full immage as we play. At 11800 FPS, things change drastically.

To find out, you can watch the video above.

In addition to slowing down Super Marios Bros., we also get a look at slowed down version of a modern LCD screen, including the startup sequence of an XBOX One and a game of HALO.
