A Spanish localization for The Legend of Zelda: Ocarina of Time was planned by Nintendo of Europe's Madrid branch, only to be scrapped partway through due to production difficulties faced by the main development team in Japan. Consequently, the Spanish release of the game used the English-language ROM, bundling the cartridge with a 150-page booklet containing all of the game's text in both English and Spanish. The cumbersome nature of the guide and the potential risk of encountering spoilers while flipping through it was considered enough of an issue that Spanish advertisements for The Legend of Zelda: Majora's Mask heavily emphasized the inclusion of a proper localization. Despite this, the guide's Spanish-language text was not added back in for the Virtual Console re-releases of Ocarina of Time.

If the Song of Healing in The Legend of Zelda: Majora's Mask is reversed, it sounds similar to Saria's Song from The Legend of Zelda: Ocarina of Time. While this may seem unintentional, the inputs to perform each song are also reversed from each other, with Saria's Song being played by pressing Down, Right and Left, while the Song of Healing is played by pressing Left, Right and Down.

The Goron Tunic, meant to protect Link from heat and reduce damage taken from lava, also affords the same protection against acid and spikes due to both being coded to use the same hit detection as lava.

While Link being able to manually jump either on his own like in Zelda II: The Adventure of Link or through the use of an item like the Roc's Feather from The Legend of Zelda: Link's Awakening is a recurring ability in the series, several 3D installments forgo this in favor of having Link jump automatically at the edge of a platform. There are conflicting claims by series producer Eiji Aounuma and series co-creator Shigeru Miyamoto as to who thought of the automatic jump during the development of The Legend of Zelda: Ocarina of Time and why. Aonuma claimed the autojump was directly inspired by the Roc's Feather and he had it implemented due to his own poor ability at playing platform games, wishing that the game could do the jumping for him. Miyamoto on the other hand claimed that he had thought of the autojump one morning and sprung it on the development team, who were planning to add a manual jump and were previously used to making Mario games, as an intentional limitation to see if they could "do all kinds of things." Manual jumping would be incorporated into a 3D Zelda game for the first time with The Legend of Zelda: Breath of the Wild.

Although Majora's Mask is a direct sequel to Ocarina of Time, there was an officially licensed novel released set shortly after the events of Ocarina of Time. "Link and the Portal of Doom" was written by Tracey West and published by Scholastic in 2006 as part of the Nintendo Heroes series.

In the book, a mysterious portal suddenly appears in Hyrule which absorbs all things around it and threatens to destroy the land. Link and Navi have to travel across Hyrule to learn five parts of a song which will destroy the portal.

Although officially licensed by Nintendo, it's considered to be non-canon.

Eiji Aonuma started developing Majora's Mask because he had no interest in remaking new dungeons for Ocarina of Time's Master Quest mode.

If the game detects that its cartridge is a pirated copy, Zelda's hair will turn into a giant pentagon in cutscenes, fishing will always result in a hooked fish escaping after 51 frames of animation, and Spoiler:the exit to Ganon's Castle during the escape sequence will be blocked off to Link, as Zelda will run right through the bars, leaving Link behind and making the game impossible to finish.

In a 1999 interview published in a Japanese strategy guide for Ocarina of Time, series creator Shigeru Miyamoto revealed that Chain Chomps from the Super Mario Bros. series were planned to appear as enemies in Gerudo's Fortress. According to Miyamoto, the Chain Chomps would be able to capture Link and wrap him up in chains, requiring him to use the Megaton Hammer to break them and free himself. Chain Chomps were present up until the final revisions of the game; Miyamoto did not explain why they were removed.

At one point in the Spirit Temple in The Legend of Zelda: Ocarina of Time, Link must fight an Iron Knuckle that turns out to be a hypnotized Nabooru, who returns to her senses after being defeated. By clipping the camera through her Iron Knuckle armor, you can see her head modeled underneath her helmet, likely to facilitate the post-defeat cutscene where her armor falls off.

Furthermore, every other Iron Knuckle in the game also has a placeholder Gerudo head modeled underneath the helmet. While much of the head's face is obscured by chainmail, the details that are present indicate that it is most likely an early version of Nabooru's design; of note is that the head's hairstyle is closer to that seen on Gerudo Village's guards, implying that this element was reused for them when Nabooru's design was revised to the version seen in the final game.

This placeholder head is also present inside the Iron Knuckles that Link encounters in The Legend of Zelda: Majora's Mask, due to that game reusing many assets from Ocarina of Time.

Much like how Bowser's laugh in Super Mario 64 is sped up for use as the Boo's laugh, Ganondorf's laughter is sped up to create the laughter of the Poe Sisters in the Forest Temple.

After slashing a sign with your sword in Ocarina of Time, playing Zelda's Lullaby while near the sign will repair it. Once the song is finished, the solving a puzzle jingle plays and the sign magically repairs itself.

This same thing happens in Majora's Mask with playing the Song of Healing.

In early footage's of the game the spirit temple's boss door was a regular door instead of the huge designed door with a lock on it found in the final release.

In order to gain access to the Master Sword, the player only needs to know the Song of Time. This is because the game's flags assume that, as the player knows and can play the Song of Time, then the player will have triggered the following:

• Gotten the Ocarina of Time
• Have all three spiritual stones

The game assumes these things because the player needs to have all 3 of the spiritual stones to trigger the cutscene in which they learn the Song of Time (which is also where the player obtains the Ocarina of Time). When playing the Song of Time, the game assumes that the player already has them.

This also extends to the Medallions as well. In order to trigger the cutscene in which Zelda gives the player the Light Arrows, as well as access to Ganon's Castle, the game only checks for the Shadow and Spirit Medallion. Even if one uses a cheat device/debug menu to remove the Light Medallion from Link's inventory it will still play the cutscene. This works because much like the Door of Time opening the game assumes things. In this instance the game assumes that the player:

• Have the Light Medallion.
• Obtained the Forest, Fire, and Water Medallion.
• Triggered the Nocturne of Shadow obtain cutscene.

The reason the games assumes these things are:

• The player is unavoidably given the Light Medallion in a cutscene, so the game has no need to check for it.
• In order to get the Shadow Medallion, the player would need to have triggered the Nocturne of Shadow cutscene, as well as having obtained the Forest, Fire and Water Medallions to trigger that cutscene, so the game doesn't check for them, as the game assumes that, as the player has the Shadow Medallion, you must have gotten them.

Since the Spirit Medallion isn't tied to getting another Medallion, or forcibly given to the player, the game also checks for it as well.

Dark Link mimics all of the player's moves and actions (save for a few.) The amount of health he has also corresponds to the amount of Heart Containers the player has by the time they fight him, potentially making him very durable or quite weak.

According to an interview with Shigeru Miyamoto conducted while the game was still in development, Navi was originally intended to have romantic feelings for Link and was even jealous of Princess Zelda. Though it seems that these details were left out in the final game.

In early trailers of the game Link's bombs were slightly different. They were more round and a much darker blue.

In early versions of the game the shooting gallery mini game had more things Link can shoot instead of just rupees. Footage shows Link shooting bombs and other targets which are not in the final version of the game.

In early versions of the game Sheik's eyes were blue, but were changed to the red in the final version.

Taking out a Deku Stick near a group of butterflies and leading one away from the group will result in the butterfly turning into a Fairy.

The bassline for the The Song of Storms sounds very similar to the bassline for the Castle Theme from Super Mario World 2: Yoshi's Island.
