Super Mario World es el primer juego de Mario en el Super Nintendo, apresurado y modificado para su fecha de lanzamiento.

A pesar de eso, se considera un punto alto de la franquicia, en parte debido a la cantidad ridícula de no linealidad y secretos dentro de los niveles. Además, Yoshi.

Unused levels
Early levels that still linger in the ROM.
Version Differences
Those dolphins had it coming.

Sonidos Sin Usar

Existe un sonido sin usar en la ROM , Que fue usado después en El siguiente juego. File:SMWYoshiColor.ogg

modos de nivel sin usar

capa 1 horizontal en capa 2 vertical

Sprite ID: EC

Cuando este objeto se coloca en un nivel, el nivel comenzara con la sección de Capa 1 horizontal, luego este cambiara a una sección de Capa 2 vertical . solo funciona en niveles con el modo de diseño colocado en 05 o 06.

Niveles Traslucidos

parece que el nivel se desvanece

modo de nivel: 1E y 1F
El juego contiene 2 modos traslucidos: uno para el Capa 1 horizontal /niveles de fondo (1E), y otro para los niveles con Capa 1/Capa 2 horizontal (1F). Ambos modos son completamente funcionales .Su posición al final de la lista sugieren que fueron "agregados" en algún punto avanzado en el desarrollo

imágenes tempranas mostraban una zona pastosa inundada usando el modo 1F , con el agua en una capa y la tierra en otro.esto pudo ser abandonado por la obvia falta de una capa de fondo usando este modo, y puede haber provocado la posterior adición de un modo de agua de capa 3 no transparente.

Unused Background and Sprite Graphics Indexes

Object graphics indexes: A, E
Graphics-wise, index A (Switch Palace 2) is identical to index 4 (Switch Palace 1), except it uses tileset 3, which is normally used by underground levels and castles. As a result, all tileset-specific objects are scrambled, making the index mostly unusable.

Index E (Underground 3) is identical to indexes 3 and 9 (Underground 1 and 2), except it uses a forest/mountain background GFX bank. This would have allowed for above-ground rocky levels, similar to those of World 6 in the New Super Mario Bros. series.

Sprite graphics index: F
Index F is identical to most of the other sprite indexes, save for the SP4 GFX bank (14), which only appears in one other index (B, Switch Palace). GFX bank 14 contains the pipe, block, Bullet Bill cannon, and Yoshi Coin graphics seen in every background tileset, none of which are used by any sprite in the game. It's possible that a set of sprite graphics existed in this bank at one point during development.

Vertical Dark BG Level

Level mode: 0D
Same as 0C (horizontal dark BG level), but uses a vertical layout.

Duplicate Horizontal Layer 2 Level

Level mode: 0F
Duplicate of level mode 01.

Unused Graphics and Objects

A gigantic number of unused graphics and objects can be found hidden in the ROM. Even more stuff from earlier builds of Super Mario World can be found in the SNES Test Program.

Sprite-Based Objects

Classic Piranha Plant

Piranha Plant with Cheep Cheep filling.
Sprite ID: 1A

A classic Piranha Plant. If you've ever played a Mario game, you should know how this works. Its vine tile has been replaced in memory with one of the frames of Cheep Cheep flopping around on land. Note that the upside-down variation of this is used in Vanilla Dome 3, but its stem has been made tileset-specific to the Cave object tileset, and since both piranha plants share their stem tilemaps, this explains why the stem of this has been moved.

There is in fact code in the game to make the stem use the same tiles as the upside-down variation, but due to a bug, it doesn't work properly. There is an IPS patch to correct this problem.

Floating Platform

A big ol' floating platform.
Sprite ID: 5E

This platform will move to the right constantly once Mario lands on it. If Sprite Buoyancy is enabled in the current level, this object will act like the smaller floating platforms found in levels such as Yoshi's Island 4.

Flying Coin

Flying red coin.
Sprite ID: 7E

A red coin that continuously moves to the right like a P-Balloon. Collecting it will give the player five coins. Red coins would not make their official debut until Super Mario World 2: Yoshi's Island, five years later.

Flying Mushroom

Of the gold persuasion!
Sprite ID: 7F

Similar to the above object, this floating golden mushroom gives the player an extra life.

Flying Cage

That's clearly a cage, there are bars and everything!
Sprite ID: 88

This graphically-glitched flying cage can be put into the game. Mario is automatically placed inside the cage when the level starts, and if used in conjunction with an autoscroll object will make the cage move across the level on a set path.

Interestingly, the tile numbers and proportions used to draw the wings match up with sprite graphics found in the SNES Test Program (at least for the larger tile), making this an old leftover.

Unused Chargin' Chuck

Sprite ID: 96

This is a duplicate of the normal Chargin' Chuck, used nowhere in the game.

Swooper Spawner

A good amount of blue Swoopers.
Sprite ID: E4

This object will create many blue Swoopers at whatever Y position it's placed, acting much like the Boo spawner found in Ghost Houses. These Swoopers cannot be defeated and will hurt Mario if he tries jumping on them. Note that one of their two flying frames has glitched graphics, hinting that Swoopers had a tilemap change at some point in development, and the fact that jumping on them deals damage hints that they may have once been something completely different.

Curiously, Swoopers would keep this color scheme in future games.

Dummy Floating Platforms

Sprite IDs: 56, 58

These platforms are like the checkerboard platforms, but their sizes are 3 x 2 pixels.

Foreground Objects

Blue Coin

A coin what is blue.
FG Object ID: 16

This acts just like a normal coin, but it's all...blue.

A block what is magenta.

Hitting a P-Switch will turn these blue coins into magenta blocks. They can still be collected like coins, since the code that makes regular coins solid does not apply to this particular object.

Small Door

Want to make a hack harder? Force the player to use half-doors!
FG Object ID: 10 (Extended object)

Half-sized doors that can only be entered by Small Mario. Both normal and P-Switch versions are coded in the game.

Question Mark Block with Shell

That ? Block had a shell in it!
FG Object ID: 37, 38 (Extended object)

Question Mark Blocks that contain Koopa shells are fully coded in the game! Well, not just a Koopa shell. The actual Koopa is still inside, and it will get back up if you wait too long. For some reason, it has no collision data for being hit with a fireball; the fireball will pass right through it.

Empty Turn Block

FG Object ID: 2E (Extended object)

Acts like a Turn Block with an item inside, but doesn't actually contain anything.

Bounce Block

A rude awakening for Mario.
FG Object ID: 39 (Feather - Extended object)
Block with "Nothing" not defined as an object but is in Map16 at 12B

These blocks aren't activated by Koopa shells or jumping, but by running into them from the side. They are finished, but the object part of this block uses the wrong graphics (hinting that something else other than the P-Switch and Springboard was here). Two versions of this block are coded: one with nothing in it, and one with a feather, the latter turning into the former when hit. Similar blocks appeared in Super Mario Bros. 3.


That's a wacky weed.
FG Object ID: 81 (Extended object)

An object-ified version of the seaweed commonly seen in underwater backgrounds. This is only found in the Ghost House tileset, and was likely intended to appear in the Sunken Ghost Ship.


The grass object, inserted via Lunar Magic.
FG Object ID: 3F X5 where X is the object length (Plains tileset only)

In the tileset-specific object set, Bushes 4 and 5 are considered unused, although Bush 5 is finished and works fine. The graphics for it are also finished, available in the forest tileset.

Conveyor Ropes

...carnage? A bit more carnageous
FG Object ID: 36 X_ (Flat), 37 SS (Diagonal) (Mountain tileset only)

These are completely functional conveyor belts using special animated rope tiles. They can go either left or right, and the diagonal ones can face either direction, giving a total of six different unused ropes.

Note Block (All Sides)

FG Object ID: 27 (Extended object)

A Note Block that will bounce Mario away from all sides, not just the top, similar to the pink Note Blocks in Super Mario Bros. 3.

Overworld Sprites


Don't worry, he won't throw Spinies.

This Lakitu will follow Mario around on the main overworld map, but he won't appear on any submaps (e.g., Vanilla Dome). Lakitu can be activated by hex editing a save state and changing address 19FB from 00 to 01.

This was most probably meant to appear on levels with Lakitus in them, but it was never coded to do such. Besides that, the only Lakitus in the game appear in submaps.

Blue Jay

Something like this?

Map bird

This odd-looking bird also follows Mario around on the overworld map, but it will also appear on submaps (except Vanilla Dome). Like the Lakitu, it can be activated by changing address 19FC in a savestate to 02.

It has been suggested that the bird was used around levels that contained the flying cage, since the mysterious winged objects holding up the cage use a blue palette.

Piranha Plant


The Classic Piranha Plant really got shafted in this game. This is a sprite meant to go on the overworld as decoration, but it's never used.

Koopa Kid

Only three kids. Huh.


Three Koopa Kids are actually present on the overworld map, but are never visible; the path tiles that were originally supposed to make them appear were changed into oddball corner tiles and used in the Star World. Unlike the rest of the overworld sprites, these actually had a purpose – they were to drag you into levels, much like the hands in World 8 of Super Mario Bros. 3.

The positions of the sprites (visible in Lunar Magic's overworld editor) suggest a vastly different overworld layout at the time of their "removal" than what was seen in the final.

Other Unused Graphics

Hills Background Star

Star light, star bright, star pulsating in the night
An animated star tile found in the hilly and Ghost House background tilesets. It's not used in either. In the final game, a different tileset is used for starry nights.

Early Yoshi Berry


This rounder, shinier, non-animated version of the Yoshi berry is loaded into VRAM at the beginning of each level, but is immediately overwritten with the animated version, which looks much different. In fact, three different versions of the berry graphic exist in the ROM, as shown below:

Fire-Spitting Dino Rhino

That's a spicy meatball! Urp

Dino Rhino was supposed to have an actual attack! These frames and a vertical version of Yoshi's fireball appear in the Dino Rhino tileset. In the actual game, Dino Rhino just walks back and forth; only the smaller Dino Torch actually attacks.

May I ingest you?

Interestingly, one of the transformed kings in the Super Mario All-Stars version of Super Mario Bros. 3 uses a scaled-down, differently-colored variant of the horizontal frame with a crown tacked on top.



Several unused Yoshi parts intended for the ending.

Yoshi Dust

Yoshi Dusted!

This dust is supposed to appear when Mario hops on Yoshi, but it's unused in the final game. Game Genie code 8B68-AFDC will enable this feature.

Iggy's Hair

In the game, Iggy and Larry both have the same hairstyle.

Slick.Also slick.

However, in Super Mario Bros. 3, Iggy had a significantly different hairstyle. Graphics for this hairstyle do exist in Super Mario World, but are unused:

Disembodied hair! Run for your lives!

If used, it would look like this:

Not rainbow, but 100% spikey!The spikes know all.

This seems to have been a mere oversight, as Iggy has his proper hair style during the ending. The tilemaps used during the ending are separate from the in-game ones, hence the discrepancies.

Correct hair in exchange for some incorrect palettes.

Morton and Roy's Attack


It seems that Morton and Roy were intended to have a secondary attack! This makes sense, since both of them have the same appropriate frames as Ludwig, who has a fireball attack.

Placeholder Block Graphics

Before After
Off! On!

These placeholder graphics for the on/off and spinning blocks are loaded before the animated versions are. "ブロック転送" means "Block transfer".

Early Brick Graphics

Early Final
SMW-Bricks-Early.png SMW-Bricks-Final.png

An earlier version of the bricks seen in the boss fights. Compared to the final version, the early one is poorly shaded.

Flying Birds

If birds evolved from dinosaurs, why are there still dinosaurs?

Why does Luigi have so many of those creepy Mario masks anyway?

The birds found atop Yoshi's House have two unused flying frames. While these were left unused in the original game, the tiles found a purpose in the Game Boy Advance remake during the 96 exits cutscene.


Two less than seven!

Graphics for a 5-Up bonus, which can only be seen via a glitch.

Older Title Screen Graphics

Super Mario Bros. 4

4 is one more than 3!

These graphics appeared in an early version of the U.S. title screen, and are still present in the ROM. Strangely enough, they are not present in the Japanese ROM, even though the official Japanese label art did have the subtitle of "SUPER MARIO BROS. 4".



Just the word "AND". Was probably supposed to appear in the copyright line, e.g. "© 1990 AND 1991 Nintendo".


Older Level Layout Leftovers

Busted Beetle
A Buzzy Beetle can be found at the very end of Donut Plains 2, stuck inside a wall. Because the screen slowly autoscrolls at that point, it can never be seen, and even if it could be seen, it would just fall through the floor.

Pipe out of order, please call an actual plumber
There's a pipe in Vanilla Secret 1 that leads to a secret exit. In the screen right above that one, there's warp data that would take the player to the same exit! However, the pipe is not warp-enabled, and even if it was, there's no way to enter the pipe, since there's no place to stand.

Unused Red Switch Palace

Unless you plan to tackle Star World 5, there's really no point.

Another instance of the Red Switch Palace map tile is coded into the Valley of Bowser. There's no way to reach or activate it without hacking the game. Trying to enter this level leads to Level 112, which points to the Test Level. The actual level ID of the Red Switch Palace is 11B.

Interestingly, Valley of Bowser 3 has its Enable path on secret exit value set to Left, whereas all other single-exit levels have it set to Up, implying that there was a path there at some point. Nintendo probably figured the player would have little need for red Switch Blocks by this point and (wisely) decided to make the Palace accessible from Vanilla Dome 2.

Boss Door

Left: Regular door. Right: Groovy door.

The door on the left is how the boss door appears in the game. The door on the right represents how the different 8×8 tiles stored in VRAM comprise the boss door. Each color is a different 8×8 tile.

Interestingly, the graphics for the orange, purple, and green tiles are identical, but are stored as separate tiles. This suggests that the door once had a much different appearance, and the purple and green tiles were originally used for something else, like doorknobs or hinges.

Overworld Paths

Displaying the future.

There are some blank tiles in the overworld graphics banks, which are drawn over the pathways Mario takes. These tiles were once used by the developers to indicate where the unrevealed pathways are.

This feature can be enabled with this patch:

Reserve Starman

In-game colors Corrected colors
Meh. WHOA!

At one point, it was possible to have a Starman in the reserve item box (though exactly how it would get there is a mystery). There is even a routine that specifically checks for the Starman item ID (03) and cycles the colors appropriately, though it appears to use incorrect palette values (00 02 04 02). Shifting each value left by one bit (00 04 08 04) fixes this.

Pro Action Replay code 7E0DC203 will force a Starman to appear in your reserve item box.

Goal Post Bottom

Just as anyone with Lunar Magic discovered when placing the goal

Though never seen in-game, Goal Posts have a bottom tile. It's likely that they were intended to float above the ground at one point, much like the similarly-styled midway points do in the final game. Unfortunately, the rounded part of the bottom tile was overwritten with large bush graphics at some point in development, causing the glitched appearance seen above.

Unused Bonuses

To do:
Upload a better video that only shows the Wiggler bonuses without bouncing on other enemies.

Normally, the bonus table caps at 1-Up after stomping eight enemies in a row. However, due to a programming oversight, this does not apply to Wigglers! Starting from the tenth stomp, you'll receive a 2-Up, a 3-Up, and then the following unused bonuses:

  • 5-Up
  • 5 coins
  • 10 coins
  • 15 coins
  • 20 coins
  • 25 coins

After 25 coins, each successive stomp will overflow the bonus table and give a glitched bonus, which is often worth a very large number of points and coins. None of the unused bonuses appear correctly; the 5-Up pulls its attributes from the code following the bonus sprite attribute table, while the coin bonus graphics simply don't exist (though they can be seen in the SNES Test Program).

Though none of the game's levels feature more than two or three Wigglers in a row (due to their processing overhead and large sprite count), it is possible to revert them to their calm state by scrolling them off and back onscreen while floating with the cape, at which point they can be stomped on again to increase the bonus count. The easiest place to do this in the game is in Forest of Illusion 1, on the log platforms above the keyhole.

Developer's Tools

Free Movement/Instant Flight Mode

The Game Genie code DDA6-DF07 enables a free movement/instant flight mode. Hold L and press A once, and you'll be able to fly (provided you have a cape) as soon as you start running. Hold L and press A again, and you will be able to move Mario anywhere in the stage. Hold Y to speed up Mario's movement, or press L and A again to return to normal gameplay.

Boss Defeated Scene Select

The Game Genie code 7DBD-04AF will give you special controls during "boss defeated" scenes. After the scene has ended, press L + R to repeat the scene or Up + L + R to view the "boss defeated" scene from the next world.

Additionally, if you go past the seventh and final "defeated Koopa Kid" scene, you can view the credits.

Power-Up Select

The Game Genie code EDA5-0F6F enables a power-up select not unlike Super Mario Bros. 3. Hold Up and press Select to switch between Small, Big, Cape, and Fire Mario.

Yoshi Select

The Game Genie code ED60-642D will let you choose what Yoshi you want on the map screen. Press Select to cycle through the different Yoshi colors (None, Yellow, Blue, Red, Green).

Instant Level Completion

The Game Genie codes DDC1-64DD DDC5-6DAD allows you to instantly complete any level, even ones you have not already beaten. Press Start then Select to complete the level via the "normal" route. Press Start, hold A, and press Select to complete the level via the secret goal, if the level has one.
