Super Mario Bros.: The Lost Levels is a video game released for the Famicom, Game Boy Advance, and the Virtual Console. It is a sequel to Super Mario Bros. that, prior to the Virtual Console release, was exclusive to Japan. This game is known as Super Mario Bros. 2 in Japan. The reason for it being replaced by another game in the US is that Nintendo of America thought it would be too hard for American audiences, and it was too much like Super Mario Bros.
