Super Mario World 2: Yoshi's Island

Super Mario World 2: Yoshi's Island is the first game to star Yoshi, and the first game chronologically in the entire Mario series. Created for the Super Nintendo, the game features Yoshi and Baby Mario, in his debut, traveling across Yoshi's Island in search for the kidnapped Baby Luigi.

The game was later re-released for the Game Boy Advance under the title Super Mario Advance 3: Yoshi's Island. A heavily-criticized sequel, Yoshi's Story, was released for the Nintendo 64 as well, and a Nintendo DS sequel named Yoshi's Island DS was also released.

Plot
One night, The Stork was carrying two babies across the sky. These two babies were Baby Mario and Baby Luigi, the future heroes of the Mushroom Kingdom. Suddenly, a strange figure, Kamek the Magikoopa, flew by on his broomstick and hit the stork. He snatched Baby Luigi, but the other baby fell down towards the ocean. When Kamek discovered his mistake, he sent his Toadies to find and capture the missing baby.

Meanwhile, the other baby, Baby Mario, had fallen on Yoshi's Island on top of a Yoshi. Along with the baby fell a map, but the Yoshi could not make sense of it. He consulted his other Yoshi friends and told him what had happened. After some talking, the green Yoshi found out what the baby really wanted – he wanted to save his brother from Kamek. So the Yoshis decided to help the baby and they set out on an adventure to rescue Baby Luigi from Kamek and his Toadies.

Remakes and Ports
Yoshi's Island is slated for a re-release on the Nintendo 3DS.

''Yoshi's Island: Super Mario Advance 3
Yoshi's Island: Super Mario Advance 3 a remake of Yoshi's Island for the Game Boy Advance as part of the Super Mario Advance‎ series. It was released in 2002 and has a number of differences from the original surrounding gameplay, content and graphics, as listed below.

New Features
Some new new features for this game are the bonus levels and the sound effects. If the player gets all 100 points on each level the will go to a secret level. Also when Yoshi jumps, flutter jumps, crouches or throws an egg, Yoshi will say something when he does those things. Since there are Bonus levels and the game is on the Game Boy Advance the map looks sightly different.

List of Changes

 * The Pause Menu has changed. Instead of one menu handling all functions, there are now two. One allows the player to put his/her Game Boy Advance into sleep mode, or return to the overworld map. The other, which is a redesigned version of the original's pause screen, allows the use of items, and displays the player's current score for the level.
 * The Yoshi's Island Mini Battle code was changed (because the Game Boy Advance didn't have X and Y buttons) to L, L, B, A, R (while holding the Select button).


 * Level Changes
 * A new room has been added to the level 1-8 (Salvo the Slime's Castle). It is between what were the second and third rooms in the original game. It has one Shy Guy-spawning pipe.
 * The original version had 21 red coins in More Monkey Madness (Extra 3), but the remake has the usual 20. There was a red coin under a Tap-Tap on a ground pound stake. This has been removed from the remake.
 * An extra Middle Ring has been added to 4-4 (Marching Milde's Fort.)
 * The final room before the boss in 4-8 (Hookbill the Koopa's Castle) has been redesigned.
 * All of the extra levels in the original game were modified for this version, most notably Kamek's Revenge.
 * The biggest change was the addition of six entirely new levels in the remake, called Secret levels. These are to the left of the Extra Levels on the map screen, and are unlocked by defeating Baby Bowser on level 6-8. Consequently, it is no longer necessary to have a perfect score in a particular World, to unlock that World's extra level.
 * The final level of the game had its name changed from "Castles - Masterpiece Set" to "Ultimate Castle Challenge".


 * Graphical Changes
 * As always, the palette is lightened to combat the original Game Boy Advance's lack of a backlight.
 * In the original, the Yoshi who completed the x-2 levels was a very dark shade of pink. However, they appeared red on the map. Similarly, the Yoshi who completed the x-7 levels was red, but appeared hot pink on the map. In the remake, the x-2 Yoshi is always light pink, and the x-7 Yoshi is always red.
 * All Yoshis had red shoes in the original. In the remake, they have different colored shoes, as in Yoshi's Story.
 * When Yoshi touches a Fuzzy in the original game, the background smears erratically and fades between random colors. The ground also ripples. In the remake, the background doesn't smear or tint. However, it does fade between white and its normal colors. The ground ripple is also less fluid in the remake. This probably happens because the Game Boy Advance is not able to handle the Super FX chip-powered graphic effects as well as the original.
 * Probably related to the above, Red Coins were given away in the original; while yellow coins followed the rippling of the ground, Red Coins did not. In the remake, all coins ripple with the ground.
 * In underground levels with "sparkling" ground, mushrooms and other foreground decorations sometimes have their palettes changed. This is done to fix a glitch where some black objects would also sparkle.
 * Sealed doors have different graphics. The boards that cover them aren't visibly bisected, as in the original.
 * Kamek's magic has a different visual effect. The colored cloud is absent, while the cycling sparkles remain.
 * The overworld map was redesigned. The path the Yoshis follow to their goal is now in a straight line, and spots have been added to the map for each world's two hidden levels. Additionally, a "world select" screen was added.


 * Sound Changes
 * The game's soundtrack was downgraded to match the Game Boy Advance's sound capabilities.
 * Several sounds in the original were replaced by sound clips similar to the ones heard in Yoshi's Story - most notably Baby Mario's cry and Yoshi's voice.

Trivia

 * In the Super Mario-Kun adaptation of this game, Mario and Luigi go to the past with Bowser by mistake. They stop Kamek from kidnapping Baby Mario and help Yoshi reunite the Baby Bros. But, in the Donkey Kong Country adaptation of Super Mario-Kun, it is revealed Yoshi does not remember anything about any adults here and nothing about the Baby Mario tantrums.
 * The game was placed 18th in the 100th issue of Nintendo Power's "100 best Nintendo games of all time" in 1997.
 * While the English version is called "Super Mario World 2", the original Japanese title is "Super Mario: Yoshi's Island". This was to draw a connection to Nintendo's earlier SNES success, Super Mario World. However, this also generated a lot of confusion as to whether to call it a sequel or not, even if it is clearly a prequel to the entire series. Similarly, Super Mario World was also known as Super Mario Bros. 4 in Japan.
 * The music for World 6 map is a stripped down version of the music that plays when the maps of the other 5 worlds are complete. Also, the music that plays in most areas of World 6 is the underground music.
 * The game places 185th in the 200th Issue of GameInformer's "Top 200 Games of All Times", the lowest ranked Mario series game.
 * The athletic and overworld music of this game returns as a music remix for the Yoshi's Island stage in Super Smash Bros. Brawl.
 * Additionally, one part of the athletic remix is the music played before giant Baby Bowser is battled, right after he transforms.
