Super Fast Mario!

Listening to: The CalTrain.

To be honest, this probably won't be nearly as funny to other people as it was to me. In any case, this is a video of a Japanese gamer playing the first Super Mario Bros. at an incredibly fast speed. I believe this is the kind of thing you can set up in readily made emulators.

The thing he keeps repeating in the beginning (chotto matte) is basically him interjecting "wait".

Ah, makes me laugh.
