In Darkstalkers: The Night Warriors, Huitzil has a fully-functional standing light kick which was never seen in any of the subsequent games. While the CPU never uses it, this attack can be performed by the player, although its slow startup and short range do not make it very useful. It can't be canceled into specials, nor does it have a rapid-fire capability. When Capcom Fighting Collection allowed Huitzil to be playable by conventional means, his animator Shisui said that this move was "so embarrassing that he wished it had never seen the light of day."
In the files of the Donkey Kong Adventure expansion, there are unused files for Rambi the Rhino as a party member, including a model; menu icons; and skills. He would have taken up two spaces on the board and been able to charge through any destructible terrain that enemies are using as cover and destroy it instantly. In the final DLC, Rambi would not appear physically in any form, but would have a gun made in his image. Rambi's model looks closer to his appearance in Rare's Donkey Kong games than his appearance in the Paon and Retro Studios Donkey Kong games, a design change that would also be carried over to Super Nintendo World's iteration of the character after Donkey Kong Adventure's release.
The matching card game has an unused card called "MatchPointsSadChef". It does not have any attached graphics. While this card doesn't exist, the game does have a happy chef card, using the chef from Comfy Cakes.
South Park: Chef's Luv Shack has an unused minigame called WBALL, where the boys would throw water balloons at passerby from a tall building. It exists in the PlayStation version and a prototype of the Dreamcast version, but it is not currently known to be playable.
While Super Donkey is thought to have ultimately evolved into Super Mario World 2: Yoshi's Island, the project was likely tossed around as a Mario or Zelda game at various points in development.
Various development assets associated with Super Donkey, which were uncovered alongside the prototype in the 2020 Gigaleak, include sprites and animations for Link, Mario, and Donkey Kong; the animation files for Link are dated to fall 1990, while Mario's animation files are dated to winter of that year. Additional files for all three characters span overlapping periods in 1991. Link's sprites and animations indicate that Super Donkey was at one point planned to be a side-scrolling Zelda title similar to Zelda II: The Adventure of Link, while Mario's animations imply that the iteration that starred him and Donkey Kong eventually morphed into the 1994 Game Boy title Donkey Kong.
According to The Cutting Room Floor, a website devoted to archiving unused content in video games, Tank is the first video game known to have unused content. Specifically, the game's score numbers are stored as one sprite even for double digit numbers, with the numbers going up to 63, despite such a score being impossible in the game due to the game's maximum 120 second timer and invulnerability frames.
The game’s files have four .txt files titled DEUTCH.TXT, ENGLISH.TXT, ESPANOL.TXT and FRENCH.TXT, suggesting German, Spanish and French versions were planned for the game. In the end, only an English version exists.
In Garfield's alternate costume texture, there is a portion devoted to Garfello, Garfield's Ninja Turtle alter ego from the Garfield Meets the Teenage Mutant Ninja Turtles short comic published in the 1992 Teenage Mutant Ninja Turtles Magazine.
There is an unused model of the Statue of David by Michelangelo in Squidward's prop set. This was likely intended for his air down strong, where he slams down with a block of marble, referencing the SpongeBob episode "Artist Unknown", where SpongeBob makes the same statue by accident. The model has a clam on its groin as censorship, just like in the original episode, but does not have the nose Squidward places on it.
As admitted by Mitsuhiro Takano (the original script writer for Star Fox 64) in an issue of Iwata Asks regarding Star Fox 64 3D, the development team had initially planned on including more aquatic stages based around the Blue Marine in the original game, but these were removed because they felt they dragged down the pace too much. In the Japanese version of the Aquas stage in Star Fox 64, Falco says:
こんな物 後にも先にも１回きりだぜ！(This is like the only time in our life we'll ever use this thing!)
English SF64's equivalent to this is "This thing will never hold together."
Apparently, this was the result of Takano feeling bad about there only being one underwater stage in all of SF64's single-player mode.
Going by files pertaining to Star Fox 64 found within the Nintendo Gigaleak, it seems one of these cut Blue Marine stages was known as カトレア (Katorea), which properly translates into Cattleya. Cattleya is a genus of orchids, which adds more credence that this was planned to be a beautiful water planet. The planet's initials (CL) show up in many other other source files, which gives clue to what it would've been like; for example, fox_edisplay references CL_SHIP0, CL_SHIP1, and fish00, whereas fox_boss.h refers to CL's boss as 鯖/saba, or "mackerel.” fox_jyuza.o meanwhile refers to a "saba snake", which heavily implies that the stage's boss would have been a giant fish creature or an eel of some kind.
On February 9, 2007, nearly a year after the game's release, director and series creator Shigesato Itoi set up an online quiz for fans who had completed the game, testing their knowledge about it. One question asks which Thief Jujitsu technique Wess uses, with the options being:
• "Super Sunset Miracle Chop Again" • "Super Chop Miracle Sunset Again" • "Super Miracle Sunset Chop Again" • "Miracle Chop Super Sunset Again" • "Miracle Chop Super Sunrise Again" • "Miracle Sunset Super Chop Again"
None of this corresponds with anything seen in the final game, and a note attached to the question clarifies that it was based on something that was removed during development, telling fans to ignore it. Because the intended answer was never confirmed by anyone on the Mother 3 development team, it is unknown what the true name of the technique was. Similarly, the question doesn't clarify what the technique would've been used for, though the phrase "Thief Jujitsu" is most similar to the Secret Thief Arts Technique that Wess occasionally uses in battle.
In a 2023 leak of unreleased content from different iOS games, an app titled Angry Birds Island - or alternatively Angry Birds Hatchery - was discovered. The prototype was simply a version of the original Angry Birds with two major differences •A mode called "Hatchery", which shows an overworld map of an island with a row at the bottom of toys and furniture •The first two worlds of the original game, but with an option to select from a set of birds, all of which appear to be hybrids of the regular birds This seemingly implies some kind of pet simulator mode with an egg breeding mechanic, not unlike the Chao Gardens from the Sonic Adventure series. It is unknown if this was planned as an update for Angry Birds or a new spin-off.
Nickelodeon All-Star Brawl 2, like the first game, contains unused calls from the announcer. Interestingly, a good chunk of these voice calls are for characters who could be clones or otherwise have a similar body shape to playable fighters, such as DoodleBob, Dark Danny Phantom, Nermal, Abrasive SpongeBob, Squilliam Fancyson, and La Tigresa. Perhaps most interestingly, Lucy Loud's ghost ancestor, Lucille Loud, is the only The Loud House character with an unused announcer line, despite the show's protagonist Lincoln having been cut from the first NASB and the show being based on a large ensemble cast of sisters. Michelangelo and Leonardo are the only cut veterans from the first game with unused announcer voice clips. None of them are from new shows, with a technical exception in the form of the name "Tak", which most likely refers to the Invader Zim character, as she would fit a clone role being an Irken invader like Zim, but could also potentially be for the titular character from the Tak series, though this is unlikely given that the game series had effectively been abandoned by Nickelodeon following the cancellation of its animated series in 2009.
Strangely, before the unused voice lines were dumped and publically uploaded to the internet, an almost entirely accurate list circulated online with Goku from Dragon Ball listed as an announcer call, likely a meme-based in-joke regardless of if it is real or fake, a name which was not included when the voice calls got datamined proper.
While Flashing Eggs make cameos in the Secret Level "Yoshi's Island Easter Eggs", they are out of Yoshi's reach due to them being embedded in the ceiling at the start of each room. Hacking the game to let Yoshi use them shows that they are fully coded and retain their functionality from Super Mario World 2: Yoshi's Island, producing a Red Coin when thrown at an enemy or Winged Cloud.
King K. Rool's render pose in Super Smash Bros. Ultimate seems to be lifted from an unused character select screen render for Zelda in Super Smash Bros. Melee.
What exists as LightFoot Village in Star Fox Adventures was originally merely a subarea in a greater location known as SwapStone Circle in Dinosaur Planet. This was essentially Krystal's equivalent to Sabre's SwapStone Hollow, acting as a hub for her adventure and thus connecting together her stages such as Cape Claw, BlackWater Canyon, Discovery Falls, Golden Plains and Moon Mountain Pass. It was also where she'd utilize her namesake SwapStone, Rubble, to transport to Warlock Mountain to deposit Krazoa spirits.
In the transition to Star Fox Adventures, when it was decided to scrap Krystal's co-protagonist role, thus leaving Fox as the only playable character outside of the prologue, Krystal's stages were either removed entirely or given to and reworked for Fox. SwapStone Circle as such would be heavily revamped, expunging the SwapStone element and heavily expanding the LightFoot Village mini-area into its own full distinct location. Similarly to Dinosaur Planet, the area would link to Cape Claw. It's worth noting that within the game files, LightFoot Village is internally called "SwapCircle", as ThornTail Hollow is similarly internally called "SwapHol", referencing their original names.
In Dinosaur Planet, Krystal and Kyte were tasked by the LightFoot to lit their ancient beacons that had gone out. Doing this in turn would reward them access to Discovery Falls. This quest would appear in the final Star Fox Adventures, but re-contextualized as the ThornTails in ThornTail Hollow asking for Fox and Tricky for help in reigniting their beacons, and doing so rewards them a key that let them access Moon Mountain Pass, as well as the Volcano Force Point Temple.
What exists as ThornTail Hollow in Star Fox Adventures was originally called SwapStone Hollow in Dinosaur Planet. It more or less functioned the same as it does in SFA, serving as the hub for Sabre's adventure, connecting his stages such as SnowHorn Wastes, Walled City, Diamond Bay, Willow Grove and Dragon Rock. It was where he'd utilize his namesake SwapStone, Rocky, to transport to Warlock Mountain to deposit Krazoa spirits.
ThornTail Hollow retains most of the same layout, but has noticeable differences: the shop that was originally situated underneath the SwapStone (now WarpStone, as the character swapping mechanic was dropped with Krystal's co-protagonist role scrapped) is now its own distinct establishment settled in the middle of the map. The winding series of tunnels right by the Swap/WarpStone has been replaced by the Mother ThornTail egg mini-game. The areas it was originally connected to such as Willow Grove, Walled City, Diamond Bay and Dragon Rock were either entirely removed or split off the mainland Dinosaur Planet in orbit. ThornTail Hollow also now leads into Moon Mountain Pass on the right side of the area, and what originally led to Willow Grove in the bottom left now leads into LightFoot Village.
