Super Mario World

Super Mario World (known in Japan as Super Mario World: Super Mario Bros. 4 ) is a 2D Mario platform game and a launch title released for the Super Nintendo Entertainment System in 1990, developed by Nintendo EAD. Being a sequel to Super Mario Bros. 3, the game retains much of the elements that debuted in Super Mario Bros. 3 such as the world map and Koopaling boss fights while introducing a large variety of new gameplay mechanics, such as an expanded and less linear world map and the ability to save the game. Introduced in Super Mario World is Mario's sidekick, Yoshi and his species that share his name, where he serves as a playable mount for the Mario brothers with his own unique abilities and gameplay style.

The game was produced by Shigeru Miyamoto, featuring music composed by Koji Kondo, and graphics designed by Shigefumi Hino. Miyamoto has stated that ever since they finished Super Mario Bros., the design staff wanted to have Mario ride a dinosaur. It was believed to be impossible technically until the Super NES was developed. According to Miyamoto, sixteen people were involved in the creation of the game, and it took about three years to make. At some point during the game's development, it was meant to be released in North America and Europe under the full Super Mario Bros. 4 title, but it was later shortened to simply Super Mario World. Miyamoto has stated that this is his favorite Mario game.

The game was released to best-selling status on the SNES, received large amounts of critical acclaim, and is commonly seen on Nintendo's best games of all times on various critic listings. Much of the game's introduced characters, game mechanics, and artistic themes influenced later titles in the Mario series, where the character Yoshi was popular enough to receive a series starring him. The game was followed in 1995 by a prequel, Super Mario World 2: Yoshi's Island, which is set many years before the events in Super Mario World. The game has spawned various nongame media such as a cartoon series that is based on the game which debuted on September 14, 1991, one month after the American release. Various manga adaptions of the game have sprung up, one notable series being the Super Mario-Kun, which has their first volumes based off Super Mario World released in 1991 and is still ongoing today.

Super Mario World is included in the Super Mario All-Stars + Super Mario World compilation title released in December 1994. A port of Super Mario World was later released on the Game Boy Advance as part of the Super Mario Advance series, titled Super Mario World: Super Mario Advance 2. The original version was also re-released on the Wii and later the Wii U and New Nintendo 3DS Virtual Console. Super Mario World is one of the included titles in the SNES Classic Edition.

Story
After Bowser's previous defeat, Mario, Luigi, and Princess Toadstool decide to recuperate in Dinosaur Land. Meanwhile in Dinosaur Land, the Koopa King and his Koopalings trap Yoshi and his friends in enchanted eggs, eliminating the opposition as they secretly rebuild their forces. Shortly upon their arrival, the Mario Bros. realize that Princess Toadstool is missing. While searching, they find the Koopa Troop army. Upon freeing the friendly Yoshi, he exclaims that the Koopas have invaded, confirming that Peach's persistent captor has indeed returned and taken the opportunity to claim the princess.

As Mario and friends travel through Dinosaur Land, they uncover the Valley of Bowser, where Bowser is fought on his castle roof in his Koopa Clown Car, holding Princess Toadstool hostage. Upon his defeat, he gently drops the princess and retreats. Princess Toadstool rewards Mario or Luigi with a kiss as fireworks celebrate freedom, signifying that their vacation can resume with their new good friends. The reunited team returns to Yoshi's House where they and three other Yoshis watch the Yoshi eggs hatch into babies, removing the spell.


 * From the instruction booklet

After saving the Mushroom Kingdom from Bowser and the rest of the Koopas in Super Mario 3, Mario and Luigi needed to recuperate from their adventures. Together they agreed that the best place to vacation was a magical place called Dinosaur Land. But while Mario and Luigi reclined on the beach for a relaxing nap, Princess Toadstool disappeared, apparently seized by evil forces. After searching for hours for their missing friend, Mario and Luigi came upon an enormous egg in the forest. Suddenly the egg hatched, and out popped a young dinosaur named Yoshi, who proceeded to tell Mario and Luigi a sad tale of how his dinosaur pals were sealed in similar eggs by a group of monstrous turtles. "Monstrous turtles!," exclaimed Luigi. "Bowser and his bunch have returned!" Mario slowly nodded his head in agreement and, along with Luigi and Yoshi, set off across Dinosaur Land to find the Princess and to free Yoshi's friends. As they began their journey, Yoshi handed Mario a beautiful cape. "This may help you," Yoshi said. "Some say it has magical powers." With a little luck (and help from a magic cape), our hearty crew can defeat the seven worlds of Bowser's Krazy Koopa Kritters. Many locations are well-hidden so explore everywhere and try everything. Not all locations have to be explored to rescue the dinosaurs and save Princess Toadstool, but there are many "starry" treasures to be found in far-reaching places. You'll need to search all areas to find what kinds of treasures are there… in Super Mario World.

Gameplay
As a 2D platformer, the object of the game is to get to the Giant Gate to advance to the next level before the timer runs out. Mario (or Luigi) can jump over and on top of various platforms and obstacles and stomp on various enemies to defeat them. In addition to these basic moves, Mario can spin-jump to destroy certain types of blocks and enemies, whereas the or  lets Mario dash if held down. When Mario presses either of those buttons next to some items, he can pick them up and carry them through the level as the buttons are held. When Mario hits the Giant Gate at the end of the level, if he touches the vertically moving bar between the gates, he gets awarded star points depending on how high the bar was when he touched it. If he collects 100 star points, Mario can play a bonus minigame that helps him earn extra lives. Some levels contain a Midway Gate, which not only powers Mario up to Super Mario when touched, but serves as a checkpoint for Mario to respawn near if he gets defeated in the level.

In order to obtain most power-ups, Mario has to hit various blocks which may contain items. The basic Super Mushroom, which turns Mario into Super Mario, causes Mario to grow bigger and allows him to sustain an extra hit. When Super Mario hits a block, usually a more powerful item spawns in the Super Mushroom's place, such as a Fire Flower or the newly introduced Cape Feather. Introduced in Super Mario World is the item reserve system, where Mario can hold onto extra items should he find them while in powered up forms; players can manually drop their reserve item by pressing. If Mario gets damaged and turns into regular Mario, the reserve item automatically deploys. A newly introduced character and power-up in Super Mario World, Yoshi, appears when Mario hits certain blocks. Mario can ride Yoshi when he jumps on him, who helps Mario with his own unique traits and abilities.

If Mario gets touched by an enemy or a damaging obstacle while he is in his normal form, he loses a life. If he gets damaged by an enemy while in a power-up form, he reverts to his normal form. If Mario loses all of his lives, the player receives a game over and is prompted to continue from their last save with five more lives. Some obstacles defeat Mario instantly regardless of what power-up he has, such as falling into pits or lava, getting crushed, or not making it to the goal in time. Every time Mario gets defeated, he gets sent back to the world map.

Super Mario World returns the world map system from Super Mario Bros. 3 with more expanded features. Rather than having levels and worlds segmented, all worlds and levels are seamlessly connected to each other, with a heavier focus on multiple paths per level clearance, and thus creating a less linear map, with a few exceptions. Typically, prior to entering new areas, Mario has to defeat a castle boss, usually one of Bowser's seven children, the Koopalings. Once they are defeated, the castle they reside in is destroyed and cannot be replayed, though in international versions of the game they can be replayed if players hold and  on the castle's remains.

Secret bonus changes
After the player beats every special level, the following changes occur:
 * World Map: The colors of the map become fall-themed, like grass and the trees of the Forest of Illusion turning orange.
 * Koopa Troopas and Koopa Paratroopas: Change into Mask Koopas.
 * Jumping Piranha Plants: Change into Jumping Pumpkin Plants.
 * Bullet Bills: Change into Pidgit Bills.
 * Vines: Buds become pumpkins.

Worlds and Levels
Super Mario World contains nine worlds and 96 levels in total. Almost all worlds contain four regular levels and at least one secret level. Levels marked in yellow contain one exit, while levels marked in red contain an alternative, secret exit. Other points of interest include the Switch Palaces, Warp Pipes, and the Super Star-shaped portals to the Star World that are unlocked only when players find the associated secret exit. Switch Palaces activate respectively colored permeable Dotted Line Blocks and turn them into solid ! Blocks that can be stood on or hit from below. Once Switch Palace levels have been completed, they cannot be visited again. Warp Pipes warp players to different areas of the map, usually to different worlds altogether. Finally, Yoshis cannot be taken into castles, fortresses, or Ghost Houses, though Yoshi remains outside for the player if they exit the level. In castles, players have to defeat the Koopalings, while in fortresses, players need to defeat Reznors.

Playable characters
Mario and Luigi are the main playable characters. In 2-player mode, Mario is controlled by Player 1 and Luigi is controlled by Player 2. If Mario loses a life or completes a level in 2-Player mode, Luigi comes into play until he does the same. The two may also share extra lives on the world map. The two have identical mechanics.

Yoshis
In addition to Mario and Luigi, Yoshis of four different colors appear in the game, which may be controlled once acquired and help the Mario Bros. in many levels of the game. Green Yoshis hatch out of Yoshi Eggs, usually found in various blocks throughout the game. If a Yoshi Egg is found but the player already has a Yoshi, the egg instead provides a 1-Up Mushroom. If a Yoshi gets hurt, they run off, requiring the Mario Bros. to chase them down if they want to ride them again. Yoshis can additionally provide an extra jump boost to Mario and Luigi if they jump off the Yoshi. Some levels contain Berries, where Yoshis can eat them and produce eggs from them if enough are eaten. Yoshis can eat most enemies, though they cannot immediately swallow most shells, requiring them to spit the shells out before they eventually swallow them.

Red, blue, and yellow Yoshis are uncommon in Super Mario World. They are first encountered in the Star World, which is accessible by using the five Star Roads found throughout the game. They are found as Baby Yoshis, small and unable to be ridden. However, through carrying them, the Baby Yoshis eat the enemies they touch. When five enemies are eaten, they transform into adult Yoshis, and can be used normally. Baby Yoshis of all colors hatch from the Yoshi Eggs rescued from the castles during the ending credits of the game.

Items and objects
There are a total of six power-ups that provide transformations in the game, with one being exclusive to Yoshi. Most power-ups emerge from the blocks populated in levels, and players are able to carry an extra item in their reserve slot if they are already powered up. While the Super Mushroom, Fire Flower, and Super Star return, Super Mario World introduces the Cape Feather, which gently floats down when they appear on screen as well as being able to be spawned from defeating Super Koopas with flashing capes. The new Power Balloon is a rare item used in a few levels and serves as a temporary transformation for Mario and Luigi.

In addition to the power-up items, Mario and Luigi can encounter other level features that help them progress through the level, such as 1-Up Mushrooms granting them extra lives or Keys and Keyholes granting them access to secret levels.

Regional differences
A number of changes were made to Super Mario World when it was released internationally following its initial Japanese version. This included translating the Japanese names and words and tweaking various levels to make the game easier for international audiences.



Gameplay changes

 * Yoshis can eat the Dolphins as if they were regular enemies in the Japanese version of Super Mario World, but not in the international versions of the game, likely due to them not being enemies. However, this change was later reversed in the remake, Super Mario World: Super Mario Advance 2, allowing Yoshis to eat the dolphins in the non-Japanese versions of the game as well.

Level design changes

 * Donut Plains 2 has an added ! Block after the three ? Blocks near the beginning of the level. Similarly, Vanilla Dome 1 has an added Cape Feather in one of the Rotating Blocks in the structure found early in the level in the international version.
 * The secret exit to Chocolate Island 3 was made more conspicuous through the use of two additional arrow signs, rather than one sign found in the Japanese version.
 * In Donut Secret House, the walls at the end of the two main rooms were extended a bit to fill the whole screen.
 * In the Sunken Ghost Ship, the three 1-Up Mushrooms at the bottom of the Ghost Ship are absent in the Japanese version.
 * #3 Lemmy's Castle has a time limit of 400 seconds instead of 300 seconds. Funky also provided the players more time in the international versions of the game via the presence of nine green berries instead of the original three in the Japanese version; as having Yoshi eat green berries adds 20 seconds to the timer, this meant the international players could accumulate triple the extra time than in the Japanese version of the game.
 * In the Japanese version, the coins at the end of Funky spell out "YOU ARE SUPER PLAYER!!" while in international versions of the game, more coins were added to correctly say, "YOU ARE A SUPER PLAYER!!"

Graphical changes

 * Both the file select and mode select title screens change between the different versions. In the file select screen, the Japanese text was changed to English for international releases, and in both cases, 1991 was added to the original's 1990 copyright date to reflect when the North American and PAL versions were released. The logo was also changed to make the shadowing of the letters less pronounced and the "TM" was rewritten in the same lettering style as the title itself. As shown in the comparison of the file select screens below, the PAL version differed from both the Japanese and North American releases in height. Each version also has its own marker to denote whether all 96 exits were found or not.


 * All instances of Japanese names occurring in-game were changed to English.
 * The sign at Yoshi's House was changed from katakana (Japanese script) to the English alphabet. Also the sign has some shade in the international versions.
 * The enemy names were all translated as well, although rather than Japanese script, they were written in romaji (English letters) in the Japanese version itself. This includes the credits, the writing on Reznor's wheel, and the sign on Bowser's castle.

Textual changes

 * In addition to being translated, various other changes were made to the level names.
 * While block numbers were used in the original Japanese names, the numbers in the international version match the font style used in the lettering.
 * In the Japanese version, all level names were followed by 「コースｘ」, "Course X", but in the international version, the names were simply numbered (i.e. 「ヨースターとう　コース１」, "Yōsutā tō Cōsu 1", changes to "Yoshi's Island 1", instead of "Yoshi's Island Course 1").
 * Cheese Bridge Area, Cookie Mountain, Forest Secret Area, and Chocolate Secret's Japanese names were all followed by 「コース１」, "Course 1", but as there were no additional levels sharing these names, the numerical designation was dropped for the international versions.
 * However, the Special Zone levels were not numbered. Gnarly and Tubular were both 「おたのしみ　コース」 (Fun Course), Way Cool and Awesome were both 「マリオスタッフもビックリ　コース」 (Even the Mario Staff is Shocked Course), Groovy and Mondo were both 「スペシャリストのための　コース」 (Specialists' Course), and Outrageous and Funky were 「チャンピオンシップの コース」 (Championship Course).
 * The flavor text after defeating a Koopaling and destroying their castle was the same for every Koopaling in the Japanese version, and thus more generic. In international versions, each Koopaling is given their own flavor text.
 * While various enemies change designs after the game is changed to the Fall setting, in the credits, the replacements are given new monikers in the SNES version; in the Super Famicom and Game Boy Advance versions, their name remains the same.
 * Like the enemy names, the staff credits were also written in romaji in the Japanese version, but various small changes were still made:
 * The somewhat odd title of "Total Director" was changed to "Main Director", "Back Ground" was corrected to "Background", and all instances of "Programer" were changed to the "Programmer" spelling for the international release. "C.G. Designer" was elaborated upon as "Character Graphic Designer" outside of Japan, and various other titles were tweaked, with "Course Director" becoming "Area Director", "Course Editor" changing to "Area Data Input", and "Player and System Programer" becoming "Mario and System Programmer."
 * The spacing of certain words was also tweaked, and a colon was added to "Special Thanks" in the international version.
 * Dayv Brooks was added to the "Special Thanks" list for his translation work on Super Mario World.

Super Mario All-Stars + Super Mario World
The Super Mario All-Stars version of Super Mario World gave Luigi a more distinctive sprite where he is taller, thinner and animates differently, while in the original he is simply a palette swap of Mario and his moves are identical to Mario's.

Super Mario World: Super Mario Advance 2
Super Mario World was remade for the Game Boy Advance as the second installment in the Super Mario Advance series, Super Mario World: Super Mario Advance 2. Some of the more notable changes include new sprites for Luigi, the maximum amount of lives being 999 that can now be saved, and a list of levels showing whether the secret exit and the Dragon Coins have been found.

SNES Classic Edition
Super Mario World is one of the 21 titles included on the Super NES Classic Edition.

Graphical

 * Several graphical errors are present in the game. Of note is that the Magikoopas' unique palette has their colors ordered incorrectly, resulting in the area that should be occupied by the lightest shade of blue instead having the darkest. This is fixed in the Game Boy Advance version by giving them the normal blue palette.
 * The Koopa bosses are all depicted with three fingers on each hand. This is fixed in the GBA version. Most of the Koopalings' sprites are made to resemble their Super Mario Bros. 3 counterparts (likely to be more easy to recognize), even when the result would be off-model from their artwork, such as with Iggy only having one tooth and Wendy having a white bow with red spots.
 * Morton, Roy, and Ludwig are given green, blue, and yellow palettes respectively in gameplay. In the credits, they are given turquoise, gray, and pink palettes, respectively, However, in order to match up with their Super Mario Bros. 3 palettes, they should be given the gray, pink, and turquoise palettes, respectively. The credits also give Ludwig Morton's teeth.
 * Lemmy is depicted as being yellow, and has large fangs and spikeless arm cuffs, likely owing to having the same body as Wendy to conserve graphic space.
 * Iggy is accidentally given Larry's hair, leaving Iggy's unused except for in the credits. This error remains in the GBA version.
 * Bowser is depicted as being primarily green. This is fixed in the GBA version to make him primarily orange. In addition, he lacks the spiked cuffs on his arms. This error is kept on the GBA version. Bowser's sprite was redesigned in the Super Mario World theme of Super Mario Maker.
 * Yoshi's arms are orange, as are those of the rest of his species.
 * Due to how Chargin' Chucks' graphics are assembled, their graphics have many errors. Most conspicuously, their heads come off for a frame when they are hit. Other errors include their facemasks going behind the rim of their plastrons in certain poses, and the facemasks also being visible in front of the clapping effect. They are also assigned a green palette in-game despite being colored with blue highlights in their artwork and being given a blue palette in the credits. They also have a star in their artwork, which is absent in their sprites.
 * Despite Dry Bones being skeletal Koopa Troopas, they are depicted as being far larger than their living counterparts. They also have neck and arm bones in their sprites, but not their artwork.
 * The two lower tiles on the back-facing Climbing Koopas appear to be switched, as the lower part of the shell moves in the opposite direction as the upper part of it, and the limbs aren't oriented as they are in the front-facing sprites.
 * Spike Tops are seemingly depicted with six legs in the game, despite seemingly having four in their artwork.
 * Despite being given green feet in their artwork, Goombas are assigned the yellow palette in-game, with the yellow only affecting their feet anyway.
 * Monty Moles have incompatible designs between their jumping and running sprites, with the former having a split lip and the latter having a smooth curve for a mouth. The GBA remake continues this with Mega Mole's unique defeat sprite seen by having Yoshi eat one while playing as Luigi.
 * Due to how Mechakoopas' tiles are assembled, the sprite of one getting up from being stunned appears to have half of an extra lower jaw under its full jaw and half of an extra foot over its full foot.
 * Big Boos have lower fangs and white eyes in their sprites, but have the same faces as normal Boos in their artwork.
 * Bony Beetles have the same falling apart animation as Dry Bones, with Dry Bones' heads being particularly conspicuous.

Miscellaneous

 * In the Japanese version, the message spelled out with coins in Funky reads "YOU ARE SUPER PLAYER!!" in a typical case of . The Western versions fix the grammar to "YOU ARE A SUPER PLAYER!!" thus adding more coins to the level.
 * In the manual description for Reznor, Bowser is referred to simply by his Japanese name and surname of "Koopa," when all other instances in the manual refers to him by his first name.
 * The English localization refers to as the enemy known as Kuribon in Japan as "Goomba," either in an accidental mistranslation or a deliberate attempt to group the two creatures together, possibly to seem more familiar to players. This led to confusion in Western depictions as to whether or not the two creatures were the same thing or not until Super Mario 3D World retranslated them as "Galoombas," though Mario Party Advance seemingly made an earlier attempt with "Goombob."

Reception
Super Mario World received universal critical acclaim. The game was placed 16th in the 100th issue of Nintendo Power's "100 best Nintendo games of all time" in 1997. The game placed 47th in the 200th Issue of GameInformer's "Top 200 Games of All Time".

Sales
Super Mario World was bundled with the Super Nintendo Entertainment System making it the most sold game for SNES, selling 20 million copies.

Pre-release and unused content
Dinosaur Land was drastically different than the final version, possessing an appearance similar to the various kingdoms of Super Mario Bros. 3. Specifically, it was to feature things such as Toad Houses (which could possibly mean that Toads were once considered to populate Dinosaur Land) and more Super Mario Bros. 3-style Fortresses. In addition to this, the game originally had the subtitle "Super Mario Bros. 4"

Glitchy graphics from defeated enemies
The balls on Iggy's and Larry's platforms can be destroyed by the sliding attack, as can the Grinders (using a triangle block). This results in glitchy graphics, most likely because the developers did not intend for these enemies to be defeated. The same thing happens if Mario does a nose diving in the second level of the Bowser battle. The Big Steely is defeated as a red sprite of Princess Toadstool's head.

Miscolored overworld
In order to do this glitch, the player must go to the end of Chocolate Island 3. Under the goal, the player must jump off Yoshi to the Giant Gate so that the screen does not scroll up. If done correctly, Mario is barely seen when he finishes the level, and because Mario is not present on the bottom of the screen, the screen begins to flicker in many colors as the stage begins to fade out. When he comes back to the overworld map, the entire world is glitchy and colored with red and blue. If Mario visits Forest of Illusion or Valley of Bowser and comes back to the main overworld, the entire world will be ivory colored instead. The glitch ends if the player completes a level or visits Star Road.

Staff
Twenty-three people were listed in the credits of Super Mario World, including notable Nintendo composer Koji Kondo for the sound programming and Shigeru Miyamoto as the producer. Takashi Tezuka was the overall director of the game, listed as the "Total Director" in the original Japanese version of the credits.

Trivia

 * The 2D graphics with linear transformations in this game would later be reused for Super Mario World 2: Yoshi's Island and Wario Land 4. Additionally, the Mario, Luigi and Yoshi sprites were also reused for Mario is Missing! and Mario's Time Machine.
 * Although Mario and Luigi have back pockets, they are not shown with those details in their artwork.
