This is the American version hence the name but will still work on all DS machines.
Super Mario World 2: Yoshi's Island for the SNES was revered as one of the greatest side-scrolling platformers ever made. The light-hearted art style and compelling game play defined a genre. Now, return to the colourful wilds of Yoshi's Island in a new platforming adventure for the Nintendo DS. Kamek has captured Baby Luigi, and now Yoshi and his band of babies must rescue him. This time, Baby Mario, Baby DK, Baby Wario and Baby Peach are along for the ride. Each one gives Yoshi access to unique powers: While they cling to his back, Baby Mario gives Yoshi speed, Baby DK gives him strength, Baby Peach gives him the ability to fly and Baby Wario gives him magnetism. All of Yoshi's classic abilities are on full display. Players gobble enemies and either spit them out immediately, or turn them into eggs that they can throw at items and enemies. Pound the ground to flatten whatever's underneath, and flutter jump to traverse precarious heights. In certain areas, Yoshi can even morph into special vehicles. Thanks to the power of the Nintendo DS, all of the lush vistas and perilous paths of Yoshi's Island span two screens. Players hit objects on the top screen while using the touch screen, and tackle super-tall enemies that fill both screens. Hidden in every level are flowers, stars, red coins and character coins, so even after players finish the game, the challenge continues.
