Alternate Elemental Arrows

Using GameShark codes, you can equip the individual elemental arrow icons to the C buttons, rather than having the magic combine with your bow. These items are used for display only on the pause screen, but function as normal elemental arrows.

Beam Blade Attack

To do: Remnants like what?

In pre-release screenshots like the one at right, Link is seen using a beam blade attack similar to the one he is able to use when his hearts are full in previous Zelda games. While this attack never made it into the final version of the game, remnants of it still exist in the code. The beam blade can be partially restored in the game using these leftovers.

Dark Link Behavior

Dark Link may be the enemy with the most extensive coding in the game, and the programmers certainly considered all options. Notably, he reacts to the player casting Nayru's Love, which will cause him to shield a lot and generally get out of the way, even though you cannot normally get that item before defeating Dark Link since it's located outside the Desert Colossus, which requires crossing the Haunted Wasteland, which in turn requires either the Longshot (obtained from beating Dark Link) or Hover Boots (obtained in the Shadow Temple, which can only be accessed after beating the Water Temple).

Seeing as the actor is just a shell which inputs buttons to the Link actor, Dark Link can also swim and dive in water, as well as climb ledges. If you are Young Link, Dark Link can also use crawling holes. However, because Dark Link has no animation for getting hit while swimming, it will instead cause him to slowly float to the sky.

Iron Knuckle Head

In the pre-boss room before Twinrova in the Spirit Temple, Link fights a brainwashed Nabooru inside an Iron Knuckle's armor. If you position the camera so that it clips into this Iron Knuckle's model, you will see Nabooru's head. If you do the same to any other Iron Knuckle in the game, you will also see a head that looks similar to Nabooru's with the same textures but has significantly different structure and design. The head is wrapped in chainmail, which covers almost everything below the nose. Also, due to the way the head is modeled, the head has no eyebrows.

The most interesting differences are that the earrings are texture-less gold hoops and that the design of the head ornament is different. This alternate head model is either an earlier version of Nabooru's head, or it was meant to be directly revealed in the same way as Nabooru's, showing that all Iron Knuckles are actually Gerudos.

Either way, regular Iron Knuckles vanish when defeated, so their true face is normally never shown. The head itself was removed in the 3DS remake, but it's still present in the model, just not in-game (with the logical exception of the one that Nabooru actually comes out of). However, when they shed enough armor in combat, a distinctly human neckline can still be seen in all versions (including Majora's Mask).

Regular Iron Knuckle	Pre-Boss Iron Knuckle

Sold Out Item

"SOLD OUT" is an icon that is normally only displayed in the Bombchu Shop in the Back Alley for Bombchus that you have already bought. However, if hacked into Link's inventory as an item, it works exactly like the Master Sword because it's linked to the same action (0x03). The GameShark code 8011A638 002C (US 1.0) adds SOLD OUT to Link's B button.

Triforce Transition

There's a very cool Triforce transition in the game, however, it is not used anywhere. You can force the Triforce transition to appear with the GameShark code.

Unused Child Malon Spawn in Talon's House

Inside Child Malon's actor file, there are three lines of code that spawn her in Talon's House at night after completing the quest to wake Talon in Hyrule Castle. However, Link cannot normally enter Talon's House at night. Trying to enter the door spawns a dialogue box with Talon saying that Malon is sleeping. Even if the player were able to bypass the dialogue box and enter the house via hacking, Malon would still not appear, because the map does not load an actor or object for her.

However, adding her actor and object to the map and bypassing the dialogue box shows that Malon exhibits the same behavior as she does when she appears in Lon Lon Ranch during the day, teaching Link Epona's Song.

Song of Time blocks

To do: someone needs to check MQ Dodongo's Cavern; that has Song of Time blocks accessible as child and adult.

Song of Time blocks in the game are actually programmed to travel through time; that is they're present on the map either as adult or child, and playing the Song of Time will transfer the Song of Time block from the child to the adult timeline and vice versa. This is actually kind of hinted at in Goron City, in the lava room, where the Song of Time blocks are present as child by default but can be transferred to adult using the Song of Time, which makes it clear that the developers wanted to make use of this mechanic to solve puzzles. Except for the single case in Goron City, all Song of Time blocks in the game are accessible only as adult because they're found either in the adult dungeons or in Dampé's Grave, so this mechanic goes unused. On top of that, a handful of dungeons have the Song of Time blocks set as temporary flags that get reset as soon as you leave the dungeon, so the state of the Song of Time block doesn't get saved either way.

The Song of Time blocks in the Ice Cavern (in the room with the block puzzle) defy this logic as they are not present either as child or adult until you play the Song of Time to make them appear.

Debug Content

Nearly a decade after Ocarina of Time was released, a debug version of the game's Master Quest spinoff was leaked. The ROM was used by testers at Nintendo of Europe to test Master Quest prior to its GameCube release.

Decompressed by default, it had many debug features that weren't present in the retail versions of Ocarina of Time or Master Quest. These included a memory editor, audio debugger, and a number of test maps.

While the retail version of Ocarina of Time does not contain as many debug features as the prototype, a few are still present.

Map Select

The Map Select allows you to go to any area in the game. See the Map Select section of the Debug ROM article for a detailed analysis.

Retail Game	Debug ROM

The Debug ROM contains nine test maps that aren't in the retail version of the game, while the retail game contains entries for two test maps that aren't in the Debug ROM. View the Test Maps section of this article for more details.

Inventory Editor

The Inventory Editor allows you to manually edit Link's inventory, equipment, and quest items.

To activate it, use the code and press Start on Controller 1 to open the Pause Menu, then L to open the Inventory Editor.

Erase Save Data Code

On the title screen, pressing D-Up, D-Down, D-Left, D-Right, Start, B, C-Down, L, C-Right, C-Left, A, C-Up, R, Z on Controller 3 resets the save data. This can be used in case the save data was corrupted, which could cause a crash on the file select menu. After the first input, there is a 16-frame timer for hitting the next input within the sequence (which reverts the timer back to 16 with each correct input).

Ura Zelda Leftovers

An add-on was originally planned for Ocarina of Time. Known by the development nickname Ura Zelda, this expansion would make use of the 64DD, a disk drive accessory for the Nintendo 64.

Title Screen Disk Tag

It is possible to trick the game into believing you have inserted an Ura Zelda disk. This can be done with a Japanese-region Ocarina of Time ROM by changing the bytes at 0xB9CCD0 from Ocarina of Time's identifier, EZLJ, to the identifier of another 64DD disk in your possession. The game will then recognize the 64DD disk as Ura Zelda.

This will cause the game to display a Disk tag on the title screen. In addition, save files with Disk tags appended will no longer be greyed out. However, the game crashes if you try to load them, perhaps because it is trying to access non-existent files on the disk.

Alternatively, you can enable the code D00EB36E 0001 801F0ADB 0004 (NTSC 1.0) while on the title screen to display the Disk tag.

Save File Disk Tag

By using the codes below, it is possible to append a Disk tag to your save file.

The tagged file is greyed out by default and cannot be opened unless a 64DD is attached to the system, and the game is tricked into thinking you have the correct disk inserted using the method detailed in the section above.

Test Maps

The retail version of the game contains two Map Select entries that were presumably used to test the 64DD add-on.

64DD TEST n64dd SetDiskVersion

The first entry is 64DD TEST n64dd SetDiskVersion. Selecting this option normally freezes the game. It would've been used to enable the 64DD Mode in the game. However, if you have a 64DD attached to your system, the following message will be displayed:

Japanese	English
ディスクを差し込んでください。	Please insert a disk.

No Ura Zelda disk has ever been leaked, so it is impossible to test this option using the right disk. If you insert another 64DD disk, the following message appears:

Japanese	English
間違ったディスクが差し込まれてい る可能性があります。正しいディス クに交換してください。 ディスクを取り出してください。	It's possible that you have inserted the wrong disk. Please switch it for the correct disk. Please remove the disk.

64DD TEST2 n64dd SetDiskVersion

The second entry is 64DD TEST2 n64dd SetDiskVersion. Selecting this option has no effect, even if a 64DD is attached to the system. This would've turned off the 64DD Mode in the game, hence why it does nothing.

Error Messages

Error messages indicating that the wrong 64DD disk is inserted are another relic from Ocarina of Time's past. This text can be found starting at 0xB9CDF0 in a decompressed 1.0 ROM. The messages were even translated into English.

Check to see if the proper disk is inserted.
Please insert the disk the correct disk.
Do not remove the disk when the access light is flashing.
Please read the instruction manual for details.
Please read the instruction manual for details.
Please insert a disk.
Please insert the disk again.
Please remove the disk.

These messages can be viewed on a decompressed US-region Ocarina of Time ROM by attaching a 64DD to your system, then changing the bytes at 0xB96B0A in ROM (or $1D2C5A in RAM) from FF FF to 00 00. If these bytes are not changed, the N64 enters an infinite loop while checking the region of the attached 64DD. This is because the region of the attached 64DD is, by necessity, Japanese, as the accessory never got an overseas release.

In addition, there is also an error message indicating that the Expansion Pak is not inserted. This is due to the fact that the Expansion Pak is required to use the 64DD.

Are you sure the Expansion Pak is inserted correctly?

Files Replaced

ovl_64dd would have rewritten the following files with files on the Zelda disk:

Scene File	Title Card Image File	Location
ydan_scene	g_pn_06	Inside the Deku Tree
ddan_scene	g_pn_08	Dodongo's Cavern
bdan_scene	g_pn_07	Inside Jabu-Jabu's Belly
Bmori1_scene	g_pn_01	Forest Temple
HIDAN_scene	g_pn_03	Fire Temple

jyasinzou_scene	g_pn_05	Spirit Temple
HAKAdan_scene	g_pn_02	Shadow Temple
HAKAdanCH_scene	g_pn_54	Bottom of the Well

Additionally, the room files for these scenes would likely also be replaced, since most rooms reference textures stored within the scene file.

Miscellaneous Content

Blanked Files

To do: Sort into proper section, add more detail.

The following files contain no data and were blanked out before the game's release.

01F5	gameplay_object_exchange_static
025F	object_warp2
0270	object_efc_flash
0289	object_demo_tre_lgt
0349	object_spot01_objects2
03EE	elf_message_ydan
05EF	anime_model_1_static
05F0	anime_model_2_static
05F1	anime_model_3_static
05F2	anime_model_4_static
05F3	anime_model_5_static
05F4	anime_model_6_static
05F5	anime_texture_1_static
05F6	anime_texture_2_static
05F7	anime_texture_3_static
05F8	anime_texture_4_static
05F9	anime_texture_5_static
05FA	anime_texture_6_static

Some guesses as to the purposes of each file can be made based on their filenames:

• gameplay_object_exchange_static was likely an object file that several actors could have depended on. Since files with "static" in their name aren't compressed, it's possible that the bulk of this file might have resided on rom, with the engine loading select assets on the fly.
• the object_* files are object files. All object_* files listed here are directly referenced by the game's object table.
  • object_spot01_objects2 would have been an object file specific to Kakariko Village (known as spot01).
• elf_message_ydan is one of two "elf_message" files, which contain the data for Navi's main quest hints, specifically the "spontaneous" C-Up hint Navi gives that can alternatively be brought up when Saria's Song is played. While the file is used and loaded into memory when the player is inside a dungeon and contains data for a single message ("Link, Try to keep moving!!"), there is an option that loads no "elf_message" for a given scene that still triggers the same message, suggesting that there might have been a more comprehensive hint system planned for dungeons.
• the anime_model_* and anime_texture_* files are unique in that there are no other files in the game that begin with "anime", so the purpose of these files isn't immediately clear.
