Super Mario All-Stars + Super Mario World is a compilation title for the Super Nintendo Entertainment System. It includes all the games from Super Mario All-Stars, as well as Super Mario World. It was released in December 1994 in North America and 1995 in Europe, but it was never released in Japan. The game was usually packaged with the console as the Super NES Mario set, and in North America, the game was available exclusively as such.
The original Super Mario All-Stars title screen changes somewhat to accompany the additional game. The background and linoleum color changes from blue to orange and blue to pink respectively, Super Mario World is added to the logo, and Birdo moves a bit forward, and sits down to make room for Yoshi, who is added in the background, in addition to more minor alterations.
On the game-selection screen, the Super Mario Bros.: The Lost Levels cover is labeled "Unreleased in the USA" underneath ("Unreleased in Europe" in the European release).
Unlike in the other four games, the controls cannot be switched in Super Mario World due to the Spin Jump; as a result, underneath the file menu for Super Mario World, instead of a control configuration option, there is an orange circular icon with Yoshi on it, with text reading "YOSHI!" below it. Selecting a file of the game has him winking at the player.
The European box art of the game has slightly changed to reflect the addition of Super Mario World.
