Super Mario All-Stars, known as Super Mario Collection (スーパーマリオコレクションSūpā Mario Korekushon) in Japan, is a collection of platformingvideo games that was developed and published by Nintendo for the Super Nintendo Entertainment System in 1993. It contains enhanced remakes ofSuper Mario Bros., Super Mario Bros.: The Lost Levels (Japanese: Super Mario Bros. 2), Super Mario Bros. 2 (Japanese: Super Mario USA), and Super Mario Bros. 3. There was also an alternate version bundled with the SNES and available at retail in December 1994 that included Super Mario World, although this version was never released in Japan. Celebrating the 25th anniversary of Super Mario Bros., the compilation was re-released for the Wii in 2010.
The title features complete remakes of all four NES and Famicom Disk System Super Mario titles: Super Mario Bros., Super Mario Bros. 2, Super Mario Bros. 3, and Super Mario Bros.: The Lost Levels with improved 16-bit graphics and sound. Gameplay, however, is virtually identical, with only the bonus game from Super Mario Bros. 2 slightly different, and some glitches being removed. A few physics properties were changed; for example, jumping and hitting a Brick Block in Super Mario Bros. causes Super/Fiery Mario to continue moving upwards after breaking it, as opposed to the NES version where Mario instantly bounced downwards upon hitting the block. The most notable addition is a save feature: all games now allow the player to save their status at any point in the game. Upon restarting the game, the player will begin at the first level of the world they saved in, with the exception of Super Mario Bros.: The Lost Levels, which allows the player to begin from the last level they saved in.
