Super Mario All-Stars + Super Mario World

Super Mario All-Stars + Super Mario World is a compilation title for the Super Nintendo. 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, 1995 in Europe and was never released in Japan.

The original Super Mario All-Stars title screen changes somewhat to accompany the additional game. The background and floor color changes from blue to orange, 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.

Also, the boxart of the game has slightly changed because Super Mario World was added.

Differences from Super Mario World
Although there are no huge differences to the game unlike the other games in Super Mario All-Stars, there are a few minor differences, such as the sprites for Luigi in Super Mario World. In the original game, Luigi's sprite set is identical to Mario's, save for the greener color palette in order for the second-player character to be identified as "Luigi". For the All-Stars edition, Luigi's sprite set was completely revamped in order to for the character to appear different than Mario, and performs various action poses differently (for instance, Mario slides down slopes on his rear, but Luigi slides down on his knees). Luigi also spits fireballs rather than shooting them from his fingers, resembling the attack of a Fire Bro. The changes in the sprite designs were purely cosmetic, as Luigi's gameplay performance remains identical to Mario's, unlike the gameplay performance in the later remake Super Mario World: Super Mario Advance 2.

Mid-game saving is also incorporated, which works the same as it did in the other games.

Also, Super Mario World now has four save files similar to the rest of the games in Super Mario All-Stars, where the original version only had three, and while on the map screen, the player can press the select button to reveal the option of either continuing the game or quitting. The file select is before starting the game, in the same fashion as the other four games, and when the title screen shows, pressing a button simply brings up the number of players selection. While the other games do not allow a change in the number of players after a game is started, Super Mario World allows the player to change between one and two players even when resuming a saved game, as with the stand-alone version.
