The Famicom Disk System's Minus World

Here's a bit of game history: when Super Mario Bros. was rereleased for the Japan-only Famicom Disk System, the "minus world" generated via a well-documented glitch changed along with the format. Instead of an infinite water level, players were treated to a whole suite of glitch-tastic levels, loaded with air-swimming and Princess Toadstool sprites floating in mid-air.
This kind of classic minutiae is exactly what we want out of the Virtual Console. We'd seriously buy Super Mario Bros. again for a crack at this new minus world. Check out the video after the break!
