New Mario Bros. is a ROM hack of Super Mario Bros. with changed graphics and new levels inspired by The Lost Levels and Super Mario Bros. 3. Unlike most other SMB romhacks, this one doesn't contain any warp zones that allow you to skip multiple levels.

WolfAeterni uses many well-known Super Mario Bros. glitches in this run in order to beat the game in record time.

Watch this run being played back on a real console.
