Super Mario Advance 2: Super Mario World

Super Mario Advance 2: Super Mario World is the second game from the Super Mario Advance series made for the handheld game system Game Boy Advance, and released in 2002. The game is a remake of Super Mario World for the Super Nintendo Entertainment System, bearing many new features on gameplay, content, and graphics. Mario, Luigi have voices added to them in this version. Other new features include Luigi as a playable character for player 1, more Message Blocks, and Yoshi Coins in all levels. The game was a gigantic hit for Nintendo and the Game Boy Advance, selling 3,290,000 copies in the United States and 5,460,000 copies worldwide. Additionally, Luigi's sprite has been changed and made taller than Mario to match his normal appearance, and the Mario Bros. classic game has been included in the game (like the other Mario Advance games), with multiplayer playable.

Changes from Super Mario World

 * If the player manages to collect all 5 Yoshi Coins in every single level, all the Yoshi Coins will change into Peach Coins (after watching a cutscene where this happens). The player can also check out in which levels the Yoshi Coins have been collected or not, by simply pressing SELECT.
 * Voices have been added to Mario, Luigi and all of the Bosses apart from the Reznors. Some of Mario and Luigi's voices were ripped from the first Mario Advance, while the others are new. Also, bosses yelp as Bowser does today when they are defeated.
 * Players can have up to 999 lives and save the number of lives for the next time the player plays the game.
 * Players now start out with the power up they last had.
 * There are more Message Blocks throughout the game than the SNES version. They're now also headed with the phrase "Tourist Tips" on top of each one the player gets.
 * When the player gets hurt with Cape or Fire power, the player won't become tiny and need to use the item in reserve (if any), but the player will become Super Mario/Luigi, and they will keep the reserve item.
 * The player can get the colored Yoshis in ? Blocks: a Blue Yoshi if the player is Cape Mario/Cape Luigi, a Red Yoshi if the player is Fire Mario/Fire Luigi, and a Green Yoshi or Yellow Yoshi if the player is Small Mario/Small Luigi or Super Mario/Super Luigi. This only happens after the Mario Bros. have used the Yoshis in Star World.
 * Luigi is an optional character for player 1 and he has some differences like: jumps better, runs a bit slower, and his Yoshi waits a bit to swallow an enemy (being able to spit it back out at an enemy), other then Mario's, that swallows it instantly (except for shells).
 * The player can also save half-way through a level once the player has past the half-way gate and quit. When the player comes back to that level, the player will start from the half-way gate, and it is not affected by playing another level after doing this process.
 * The rescued Yoshi Egg dots are colored instead of being a dull gray-brown color.
 * Luigi is updated to resemble his current look: tall and skinny, while Mario and all the others are still the original sprites from the SNES game.
 * The autumn changes will not occur until the player has found all 96 exits. Goombas, Koopas and other enemies now change.
 * Because there is only one run button on the GBA, it is impossible for Mario to turn around while flying with the cape, or release fireballs while holding an object.

Items & Power-Ups
The game borrows many items from the original game from which it was based, which include:

Power-Ups
Mushroom- Mario or Luigi can eat a Mushroom to become "super." Fire Flower- With a fire flower, the Mario Bros. can shoot fireballs at enemies. Cape Feather- Using this feather, the Mario Bros. can fly. Star- With a Star, the Mario Bros. will become invincible for a couple of seconds.

Items
1-Up Mushroom &mdash; If Mario or Luigi collects one, they'll get a 1-Up.

3-Up Moon &mdash; If Mario or Luigi collects one of these, they both get three extra lives. These are very rare being the first at Yoshi's Island 1.

Key and Keyhole &mdash; If the Mario Bros. put a key in a keyhole, a secret level will be unlocked.

P-Balloon &mdash; Mario and Luigi fatten up and inflate like balloons when they touch this item, allowing them to float in all directions for a short length of time.

P-Switches &mdash; When the blue switch is pressed, blocks transform into coins and vice-versa, and some invisible blocks will be revealed. If the silver one is pressed, some enemies, such as Spinies, will transform into Silver Coins. After a short period of time, the changes made by either switch will revert to normal.

? Ball &mdash; An item that is required to successfully complete certain levels.

Playable Characters
Unlike the original game, there is no 2-player mode, so Mario and Luigi don't alternatively take turns after finishing or failing a stage. However, players can choose to play as Mario or Luigi by pressing R on the map. Luigi is slightly different to Mario:
 * Luigi jumps higher and farther than Mario.
 * Luigi runs slower than Mario.
 * When Luigi flies using the Cape, he doesn't fly as fast as Mario.
 * When hurled, Fire Luigi's fireballs bounce higher than Fire Mario's.
 * Unlike Mario, when Luigi rides Yoshi, he cannot swallow any enemy. Instead, Yoshi can spit them out and use them to attack other enemies. If Yoshi has an enemy in his mouth for about eight seconds, he will swallow it.
 * If Luigi hits a Coin Block, all the coins will spill out of the block instead of collecting them one by one.

The Mario Bros. can obviously still ride Yoshi, and he has the same abilities from the original game.
 * Green Yoshi - After eating a shell, the Green Yoshi will have a special ability depending on what color the shell was. Note: Green Shells don't give Yoshi an ability. They can be spat out and used as a projectile.
 * Blue Shells - Gives Yoshi the ability to fly.
 * Red Shells - When Yoshi spits it out, he spits out fireballs instead.
 * Yellow Shells - When Yoshi lands on the ground, he makes tremors that can defeat nearby enemies.
 * Rainbow Shells - When Yoshi eats this shell, he will gain all of the previous abilities.
 * Blue Yoshi - After he swallows any colored shell, he can fly.
 * Red Yoshi - After he spits out any colored shell that he swallowed, he spits out fireballs.
 * Yellow Yoshi - After he swallows any colored shell, he can cause enemy-damaging tremors when he lands.

 * World 3 - Vanilla Dome
