This is a sub-page of Kirby & the Amazing Mirror/Unused Graphics.

This page will document regular unused graphics that could've appeared in gameplay.

Unused Pause Menu Elements

In all versions of the game, various graphics for the pause menu based on those from Nightmare in Dream Land can be found. They're translated into every supported language, but unlike the early localization graphics, these don't have used equivalents.

Graphics Location (JP) Location (US) Location (EU) Description
Kirby & The Amazing Mirror Unused Pause 1 JP.png 00608F78 0062504C 0062ED90 Japanese graphics. The text can be romanized as "Gēmu wo tsuzukeru", and translates to "Continue Game".
Kirby & The Amazing Mirror Unused Pause 2 JP.png 006096F8 006257CC 0062F510 Japanese graphics. The text can be romanized as "Mappu wo miru" and translates to "View the map".
Kirby & The Amazing Mirror Unused Empty Pause.png 00609E78 00625F4C 0062FC90 Empty graphics. Most likely used as bases.
Kirby & The Amazing Mirror Unused Pause ENG.png 0060A5F8 006266CC 00630410 English graphics. Pretty self explanatory.
Kirby & The Amazing Mirror Unused Pause FRA.png 0060B4F8 006275CC 00611310 French graphics. Translates to "Continue game".
Kirby & The Amazing Mirror Unused Pause GER.png 0060AD78 00626E4C 00630B90 German graphics. Translates to "Continue game".
Kirby & The Amazing Mirror Unused Pause ITA.png 0060BC78 006284CC 00632210 Italian graphics. Translates to "Continue".
Kirby & The Amazing Mirror Unused Pause ESP.png 0060C3F8 00627D4C 00631A90 Spanish graphics. Translates to "Continue playing".

These graphics are actually used in the game's Demo, where it used an earlier iteration of the pause menu that worked similarly to the previous game's, in which the player highlighted the options and then triggered them by pressing the A button. Only the prompt that allowed the player to check the map is unable to be selected because the player isn't allowed to pick up maps.

Unused Ability Icons

Various unused icons managed to slip into the game's internals. Some of them are leftovers from Nightmare in Dream Land.

WAIT Icon

At 00309274, 0031AE60, and 0031CD00 in the Japanese, American, and European versions of the game respectively, the "WAIT" icon that displayed when someone lost a life in a multiplayer session of the previous game can be found. Players respawn shortly after being KO'ed, so this icon goes unused. The palette remains inside the game, located at 003019D4 in the Japanese version, 0031AE40 in the American version, and 0031CCE0 in the European version.

Kirby & The Amazing Mirror WAIT Icon.png

STAR ROD Icons

At 00309634, also in the Japanese version of the game, there are graphics for the Star Rod from Nightmare in Dream Land in German.

Kirby & The Amazing Mirror Star Rod German Icon.png

Later, another Star Rod icon can be found in 00310A74, now in Japanese. It can be romanized as "Sutā Roddo".

Kirby & The Amazing Mirror Star Rode Japanese Icon.png

The icon's palette is not fully unused, however, as the orange found in it was repurposed as the palette for the damage icons in all versions of the game, and the red, yellow, and blue colors of said palette are exclusively used for the elemental damage icons in the Japanese version of the game.

KIRBY Icon

Finally, in 003099F4, there's a completely unused "Kirby" icon. These are repeated along the different language placeholder graphic, in place of where the different hurt icons should be. This icon seems to use the palette for the Star Rod icon, which makes it look... not great. Below is the icon with the Star Rod's palette applied, and a mock-up depicting how it could've looked like.

Kabyi!

Unfinished Area Names

Starting at 007B1E18, 007DB308, and 007E5770 in the Japanese, American, and European versions respectively, various unfinished/early area names for the World Maps can be found.

Early Graphics Final Japanese Graphics

It's worth noting that these graphics can also be found in the Demo's data in place of the finalized ones.

Early and Unused Map Text

There's early graphics for the Japanese text that shows up when viewing the World Map and Area Maps starting at 007B07D8, 007D8ECC, and 007E3330 in the Japanese, American, and European versions respectively. These can be seen in pre-release material. Most of these were refined and made bigger for the final Japanese release.

Early Graphics Final Graphics Transcription/Romaji Notes
Kirby & The Amazing Mirror Early Mappu.png
Kirby & The Amazing Mirror Final Mappu.png
マップ/Mappu Translates to "Map". Early graphic is very similar to the finalized graphic. The only differences are that the "マ/ma" has a hollow spot in the middle, and that the "プ/pu" is closer to the sokuon in the early version.
Kirby & The Amazing Mirror Early Modoru.png
Kirby & The Amazing Mirror Final Modoru.png
もどる/Modoru Translates to "Return". The kana were made bigger and given a few gray pixels to give off an anti-aliasing effect.
Kirby & The Amazing Mirror Early Zuumu.png
Kirby & The Amazing Mirror Final Zuumu.png
ズーム/Zūmu Translates to "Zoom". The kana were made bigger and given a few gray pixels to give off an anti-aliasing effect.
Kirby & The Amazing Mirror Early Zentai.png
Kirby & The Amazing Mirror Final Zentai.png
全体/Zentai Translates to "Whole". Paired in game with "マップ/Mappu" to make "全体マップ" (lit. "Whole Map"). The early graphic is very similar to the finalized version, as the only differences are that the early graphic has the kanji closer together and the "全" kanji has an empty pixel at the top and its bottom adjusted.

There are also unused graphics for text that doesn't have variants that's used in the final version.

Unused Graphics Transcription/Romaji Notes
Kirby & The Amazing Mirror Unused Tsugi No.png
つぎの/Tsugi no Translates to "Next". Was paired with "エリア/Eria" in pre-release builds to make "つぎのエリア" (lit. "Next Area).
Kirby & The Amazing Mirror Unused He.png
へ/He/E Translates to "To". Was paired with "エリア (Area)" and "マップ (Map)" in pre-release builds to make "エリアマップへ" (lit. "To Area Map").
Kirby & The Amazing Mirror Unused Dash.png
A simple dash character. Used in pre-release builds to separate the word "エリア (Area)" from an area's number.

All of these graphics also have leftover animation data.

Unused Kirby Sprites

Burning Kirby

Burning Kirby has hat graphics that were used in Kirby: Nightmare in Dream Land when he exited a hub door. No door in this game can trigger this animation, so they go unused. They can be found at 00540518 in the Japanese version, 0055C5EC in the American version, and 005665B0 in the European version.

Kirby & The Amazing Mirror Unused Burning.png

Cupid Kirby

Cupid Kirby has full body sprites for the animation that played when exiting a hub door in the previous game at 0059C678 in the Japanese version, 005B874C in the American version, and 005C2610 in the European version. This is odd, because Cupid Kirby isn't from Nightmare in Dream Land, so there should be no reason for these sprites to exist. The 2003 Demo also has these kind of sprites for Mini and Missile, but they were removed from the final game.

Kirby & The Amazing Mirror Proto Unused Cupid Sprites.png

Fire Kirby

Fire Kirby also has graphics for the exiting animations from the previous game, but like Burning, it's only for the hats. They're located at 004DA8F8 in the Japanese version, 004F69CC in the American version, and 00500990 in the European version.

Kirby & The Amazing Mirror Unused Fire.png

Master Kirby

Master Kirby has graphics for a hat. They only remain for the "Upwards Stab" attack. These are leftovers from an earlier point in development where Master Kirby reused Sword's hat, as evidenced by the 2003 Demo. They're located at 005DC0F8 in the Japanese version, 005F81CC in the American version, and 00602190 in the European version.

Kirby & The Amazing Mirror Unused Master Hats.png

Notably, there are more frames than what the final animation uses, hinting that the animation's length was shortened sometime after these graphics were created and then scrapped. A mockup of the final animation with matching frames is shown below.

Kirby & The Amazing Mirror Upwards Stab Mockup.gif

Missile Kirby

This is the starting sprite that shows up for three frames in Missile's transforming animation. However, it's covered by many effects and can never be fully seen under normal circumstances. If the player initiates the move while inside an air current, only some pixels will peek, but the rest of the graphic is never shown. The location of this sprite inside the game's data is in 005AD558 in the Japanese version, 005C962C in the American version, and 005D35F0 in the European version.

Kirby & The Amazing Mirror Missile Frame.png

Parasol Kirby

Like Cupid, Parasol also has full body sprites for the hub door animation from the previous game. They can be found at 00503218 in the Japanese version, 0051F2EC in the American version, and 005292B0 in the European version.

Kirby & The Amazing Mirror Unused Parasol.png

Throw Kirby

Another ability to have sprites of this type is Throw, whose graphics can be located at 00549D78 in the Japanese version, 00565E4C in the American version, and 0056FE10 in the European version.

Kirby & The Amazing Mirror Unused Throw.png

Sword Kirby

Lastly, Sword Kirby has these kind of graphics too. Kirby himself is located at 004EA658 in the Japanese version, 0050672C in the American version, and 005106F0 in the European version. His hat is at 004E9598 in the Japanese version, 0050566C in the American version, and 0050F630 in the European version.

Kirby & The Amazing Mirror Unused Sword.png

All of these graphics have leftover animation data.

Kirby Wave Ride

Kirby's damage sprites from Kirby Air Grind in Kirby: Nightmare in Dream Land can be found at 0073F758 in the Japanese version, 0075B82C in the American version, and 00765570 in the European version. No other graphics from Air Grind can be found, which may suggest that Kirby Wave Ride originally had damage mechanics, but were scrapped. Additionally, the last unused sprite, which is not from Kirby: Nightmare in Dream Land, can be located at 00740358, 0075C42C, and 00766170 in the Japanese, American, and European versions respectively.

Kirby & The Amazing Mirror Wave Ride Hurt.png

Also, the Japanese version of the game contains the Spanish sprite sheet for Wave Ride at 00397688. Said sprite sheet also has the unused damage graphics, but two sprites were partially overwritten by the "EXCELLENT!" graphic that pops up when boosting.

Kirby & The Amazing Mirror Overwriten Wave Ride.png

This was fixed in the European version of the game, but it didn't really matter since the graphics went unused anyway.

One last thing to note is that the regular damage graphics are always loaded into memory when playing Wave Ride, and that they have leftover animation data.

Unused Enemy Sprites

Gordo

Gordo has unused duplicates for their sprites in the Kirby Wave Ride sprite sheet at 00742158, 0075E22C, and 00767F70 in the Japanese, American, and European versions of the game respectively. The palettes differ slightly from regular Gordo's due to using a Wave Ride palette. They even have leftover animation data that is not used by the regular version of Gordo. This reinforces the idea of damage mechanics being considered for Kirby Wave Ride.

Droppy

Droppy has sprites with goggles, but only animations for walking and swimming, suggesting underwater Droppys were planned but cancelled during development. These sprites can be found at 00647598 in the Japanese version, 006636A8 in the American version, and 0066B3D0 in the European version. The game stores unused animation data for these graphics, being used for 3 animations.

Minny

Minny has three sprites for what seems to be jumping, aerial time, and falling. In the final game, Minny only runs back and forth rapidly. These are located in 0066AB68, 0068678C, and 006904D0 in the Japanese, European, and American versions of the game respectively. The game also has leftover animation data stored for these graphics, and each sprite is an animation.

Unused Boss Sprites

Gobbler

Gobbler has an unused sprite of him grimacing. What it was supposed to be used for is unknown, but it comes right after the graphics of him dashing underwater. The game has animation data for it consisting of one frame. It's found at 00690E78 in the Japanese version, 006B6C90 in the European version, and 006ACF4C in the American version.

Dark Meta Knight

Dark Meta Knight has graphics for a slide attack that was previously used by Meta Knight in Nightmare in Dream Land only in Meta Knightmare, his playable debut. There's no attack in both of his fights that make use of these graphics, so they go unused. The game also stores animation data for the first three graphics. The last frame, however, is briefly seen in the cutscene where Meta Knight and Dark Meta Knight fight, albeit in a completely different color palette. Dark Meta Knight himself can be found at 007BF218, 007F62F0, and 007EBE8C in the Japanese, European, and American versions of the game respectively, while the sword is at 007CD3D8, 008044B0, and 007FA04C in the same order.

Unused Enemy Health Bar Names

Stoppy

There's a single unused health bar name for an unused enemy. It says "ストッピー (Stoppy)" and is located at 002F0B34, 002EFBA0, and 002F1A40 in the Japanese, American, and European versions of the game respectively. Stoppy is a (mostly) dummied-out enemy present in the final game.

Kirby & The Amazing Mirror Stoppy Health Bar Name.png

Placeholder Names

This graphic, found at 002F1F34, 002F0FA0, and 002F2E40 in the Japanese, American, and European versions of the game respectively, is repeated 5 times between a space separating the names of bosses and mid-bosses. It's used as a placeholder for entities that don't have a defined name yet, and by the unused bytes of data for bosses and mid-bosses.

Kirby & The Amazing Mirror Unused Name Placeholder.png

An alternate version of this graphic is present just below it in the data at 002F2034, 002F10A0, and 002F2F40 in the Japanese, American, and European versions respectively. It's nearly identical to the previous one, but with the bottom pixel on each triangle deleted.

Unused Arrow

There's an unused graphic of a red arrow at 005F5C38 in the Japanese version, 00611D0C in the American version, and 0061BCD0 in the European version of the game. Previously used in Kirby: Nightmare in Dream Land to indicate what Kirby you were playing as upon entering a stage in multiplayer, it ended up unused here due to not being as useful in the open world setting of Amazing Mirror.

Unused Corner

What this graphic, located between Roly-Poly and Foley at 0066B598, 0068766C, and 006913B0 in the Japanese, American, and European versions, is supposed to be is completely unknown. It's recognized as a CHARACTER by the prototype's Debug Menu, and has one animation consisting of this very still frame.

Kirby & The Amazing Mirror Unused Something.png

According to the Debug Menu, the palette this graphic uses is used by many other graphics, such as Magic's roulette, the bouncing Master Sword, UFO's shots, Crash's explosion and particle effects, Ice's ice cubes, the Mirror Doors, food items, the levers used to unlock the air passages, and many other dust and smoke effects.

Unused Mirror Frames

Three unused mirror frames for the Central Circle are present in the game. They appear to be earlier versions of existing mirror frames.

Frame Location (JP) Location (US) Location (EU) Description
KatamProto UnusedFrame1.png 005FF0D8 0061B1AC 00625170 A frame with a space/cloud aesthetic. Could've easily been paired with Candy Constellation.
KatamProto UnusedFrame3.png 005FF5D8 0061B6AC 00625670 An orange stone frame. Its aesthetic fits with the tiles of Radish Ruins.
KatamProto UnusedFrame2.png 006004D8 0061C5AC 00625770 A mossy cave-like frame that could've belonged to Cabbage Cavern or Rainbow Route.

Unused Cut-Scene Graphics

A question mark, exlcamation mark, and a "shocked" graphic can be located near various other cut-scene graphics inside the various versions of the game. The question mark and shocked graphic are part of early cut-scenes still present in the final game, specifically the ones that play when encountering and defeating Dark Meta Knight inside the Dimension Mirror. The question mark would later be used in Kirby: Squeak Squad as a Mix or random ability essence bubble.

Unused Heave-Ho Blocks

The small and large Heave-Ho Blocks found all over the Mirror World have a modified duplicate of their graphics that allow them to use unused orange and brown tones in their palette.

Unused Tiles

Cloudy Tileset

The "cloudy" tileset that's used in the tutorial area and the Copy Ability room has various unused tiles. The first tile is a blue ladder similar in style to the floating platforms found in those areas.

Kirby & The Amazing Mirror Unused Cloudy Ladder.png

Next up is an assortment of stars in a diagonal formation. Their purpose is unknown, but their angles are similar to those of slope tiles.

Kirby & The Amazing Mirror Unused Stars.png

King Golem Tileset

A short spike tile resides inside the tileset pertaining to King Golem's room.

Kirby & The Amazing Mirror Unused Spike.png

Mountain Tileset

The "mountain" tileset that appears in some areas of Mustard Mountain and Rainbow Route has unused tiles of a barrel and various crates. The "forest" tileset uses a similar barrel, but with a different palette.

Kirby & The Amazing Mirror Unused Mountain Tiles.png

Volcano Tileset

The "volcano" tileset has an unused animated tile of a lava bubble popping. A similar animated tile is used in Mustard Mountain, but it's slower and doesn't have a dark background.

Kirby & The Amazing Mirror Unused Lava.gif

Ocean Tileset

The "ocean" tileset used in the underwater sections of Olive Ocean has an unused ladder tile similar to the ones found in Mustard Mountain. While some ladders are used in the beach section of Olive Ocean, they look nothing like this. Additionally, ladders don't appear in the underwater sections of the game, so it's clear why this one went unused.

Kirby & The Amazing Mirror Unused Olive Ocean Ladder.png

Peppermint Palace

The "palace" and "icy cave" tilesets pertaining to Peppermint Palace have two small unused circles. The first one is found in the icy cave tileset, while the second one is found in the palace tileset. What they could've been used for is unknown.

Kirby & The Amazing Mirror Unused Circles.png

Miscellaneous Blocks

Various gray blocks can be found scattered across many tilesets. The most interesting block is the one in the middle, which has a hammer symbol. It's likely that it was once used as a block that could only be destroyed with the Hammer ability.

Kirby & The Amazing Mirror Unused Gray Tiles.png

Unused King Golem Tileset

King Golem has a whole tileset that goes unused located at 009EE8AC, 00A1E720, and 00A28B84 in the Japanese, American, and European versions of the game. It includes the sprites for his body (which don't have any differences from the used sprites), a blue door similar to the ones from previous games, a huge platform and some debris. The platform and the debris use a palette that's strikingly similar to the one used in Radish Ruins, and their design appears to come from the aesthetic of that place as well. Additionally, an unused palette for King Golem located 2 palettes away from this tileset's is paired with it, highly suggesting a cut second encounter with King Golem in Radish Ruins, or an early version of his room in Moonlight Mansion.

Kirby & The Amazing Mirror Unused King Golem Tileset.png

The tileset is identified by the value 16, as so is the palette.

Debug Tileset

The Debug Room has a whole entire tileset that goes unused. They include slopes of differing heights, spikes, water tiles, and icy tiles. Some of the tiles are borrowed from Kirby's Dream Land 3, just like how Kirby: Nightmare in Dream Land did it. The text on the first and second tiles means "explosion", the third tile means "fix" or "repair", the fourth one means "hammer", the fifth one means "demo", and the last two mean "magma".

Kirby & The Amazing Mirror Debug Tiles.png

Present only in the debug room's tileset is also this numbered field, which might have been used as a template.

KatamDebugTilesNumbers.png

Dark Mind Tileset

Unlike almost every other room in the game, phase 5 of Dark Mind's room doesn't use a traditional tileset. It instead uses an animated background. However, when inspecting the room's data in a map viewer, the room actually has tiles hidden in-game that form a room identical to the unused Debug Room, sans for the alternate palette.

Kirby & The Amazing Mirror Dark Mind Tileset.png

It also comes with its own version of the Debug Tiles.

Kirby & The Amazing Mirror Dark Debug Tiles.png

All of this may mean that this room may have once been a Debug Room during development until it was repurposed as a Boss Room, or that the Debug Room's data was copied to make this room.

(Source: Vyroz)

Placeholder Tiles

These are placeholder tiles used by the designer to fill into. The second and third tiles are only present within the NLZ compressed graphics of the sub-games.

Unused Backgrounds

Placeholder Background

A placeholder background representing some mountains. You can see it in-game by replacing the background of the main hub room. To do so, change the byte at offset 0093AEF2 in the US version of the game from 1A to 16.

Some... mountains?

Unused Credits

An unused version of the credits' text, classified as background 22 and 23. It's nearly identical to the used version, but it doesn't have shadows behind the letters.

Kirby & The Amazing Mirror unused credits.png

(Source: Vyroz)

Unused Fonts

Debug Font

A fairly small font appears two times in all the regional ROMs. This was used as a debug font earlier in development, and it can still be found in the 2003 demo's Debug Menu. The palettes for it seem to have been removed, so the one you're seeing here is a recreation of how it was in the Demo.

Kirby & the Amazing Mirror Unused Font.png

It first appears at 00348660 in the Japanese version, 00363EEC in the American version, and 0036E170 in the European version. It makes its second appearance at 00D49EEC, 00D7EAD4, and DF12EC in the Japanese, American, and European versions respectively.

(Source: Vyroz)

Early Credits Fonts

Two fonts meant for the staff credits, only found in the Japanese version of the game at 00ADEB70 and 00AF2784. Previously shown in the unused backgrounds section, this font is the same as the one from Kirby: Nightmare in Dream Land. The final font adds shadows behind the characters.

Unused Characters

The credits fonts have various characters that don't get used in any version of the game.

Unseen Details

Map Blocks

When the player hasn't collected the map for a certain area, they can pause to see a partial map of the rooms they have visited. These partial maps have small colored blocks representing where the actual Area Map is. While these graphics are not unused, they're only seen in their small versions. These graphics are much bigger than what they appear to be, and the game resizes them in real time to be small. Below is a comparison between how they're seen and how they actually look in the game's data.

Seen Full

Dark Meta Knight Flap

Dark Meta Knight has a few graphics with hidden details. While these graphics and animation can be seen used by Dark Meta Knight in the introduction cutscene, it's displayed in pitch black. Looking at the sprite in a tile editor reveals that the sprite was fully drawn with the intention of having all of Dark Meta Knight's colors and details. Loading the animation in-game outside of the intro cutscene (Sprite ID 03 9E, Animation ID 00) reveals that the sprite even has an assigned palette ourside it, sporting an otherwise unused palette for Dark Meta Knight that has golden colors used in an earlier design for him. These colors turned his eyes and shoulder plate rims golden, and in these graphics, these colors are used for his sword, making it resemble Galaxia.

Kirby & The Amazing Mirror Meta Knight Flapping Color.png

These graphics can be found at 0082CBF8 in the Japanese version, 0085986C in the American version, and 00863CD0 in the European version. An animated comparison between the true color version and the seen version is below.

Full Goal Game Backgrounds

While not completely unused, the backgrounds that appear in Goal Games have a big chunk of unseen sky. The player is unable to see beyond the upper half of the second star, leaving the giant stars and light trails unseen. The sides and bottom are also slightly cut in-game.

Yellow Violet Teal Visible

Full Crackity Hack Beach Background

Similarly, the beach background seen in Crackity Hack is massive, but most of it is obscured by the actual beach and palm trees, and some of it is cut off by the borders of the screen. A large portion of the sky and most of the ocean goes unseen because of this.
