A room from Fstdan, one of the early maps recovered from the leak.

On July 25, 2020, development resources for a number of first- and third-party Nintendo games, including Ocarina of Time, were leaked on 4chan. The files seem to have been resources sent by Nintendo to iQue in order to help them develop the iQue port of the game. Lucky us!

Early Fishing Experiment

To do: Is it possible to get this working?

The file z_actor.h in the folder z_ocarina2 contains the following commit log note:

* Revision 1.204  1998-04-09 23:36:13+09  morita
*       For those who want to know the secrets of the secret project I'm
*       working on, put 1 in SEX(69) (using controller 2, hold R and press
*       L 6 times), then select "79: Water Temple Boss"....
*       When you do... there are details on the control scheme in 
*       /home/morita/JOY_FILES/secret.lst

The source code indicates that a memory register called SEX, known as "Rs" in the Debug ROM, was named by Kazuaki Morita. Morita is credited with programming the bosses in Ocarina of Time. Additionally, according to an Iwata Asks interview celebrating the release of Ocarina of Time 3D, the Fishing Pond was also his side project and brain child.

Morita: The Water Temple is in Lake Hylia. Aonuma-san designed that dungeon. The boss that appears there is Morpha. Just when I was making that, there was a landform like a pool.

Iwata: Morpha rises up out of the pool and fights Link.

Morita: Right. When I was making that boss, I casually…

Iwata: "Casually"? (laughs) I doubt you had that kind of time!

Morita: But for some reason I did. (laughs)

Morita: I just happened to have a model of a fish, so…

Iwata: You "just happened" to have it? (laughs)

Morita: Yes! (laughs) A model of a fish for putting in an empty bottle. I borrowed that and had it swim in the pool in the dungeon, and when I saw it swimming around, I thought, "Oh! I can go fishing!"

Iwata: What did you do for a fishing pole?

Morita: I took the model for something and made it a cylinder, and then… (gestures as if casting a fishing pole)

Haruhana: You used the motion for Link swinging his sword.

The aforementioned note seems to be instructions from Morita to the other staff for checking out the in-progress version of the fishing functionality he was working on. Following the instructions in the note verbatim produces no noticeable results upon entering Morpha's boss room from the Map Select screen, regardless of Link's age. Even with SEX69 (Rs69) [no comment...] set to 1, the Morpha battle starts as normal. This may indicate that the "secret" that was accessible via this method may have been removed sometime in the 7 months between the commit log note and the game's release.

However, one additional point to keep in mind is that the Water Temple boss is now number 80 in the Map Select options, while the Water Temple is number 79. This may indicate that Morita's fishing preview was created at a time before the boss rooms were split off from their Temples into separate map files, as they are in the final game. As such, perhaps if one were to attempt to enter Room 0x16 of the Water Temple (the boss transition room) without automatically being loaded into the map file for Morpha's boss room in the final game, one could still see the intended effect.

In the final game, Morpha's actor, En_Mo, contains the following strings:

fishing_line_MODE
fishing_line_model

Conversely, the strings that can be found in the actor for the fishing pond, En_Fish, are below:

fs_line_MODE
fs_line_model

Spawn An Arwing

To do: Add the chest spawn stuff from Link's actor, too.

The source code indicates that a memory register called KAZ, known as "RK" in the Debug ROM, was named after Kazuaki Morita. Morita is credited with programming the bosses in Ocarina of Time.

A file called z_actor.c in the folder z_ocarina2 contains the following code used for spawning the Arwing.

#ifndef DEBUG_MODE_NOINPUT    
    if(KAZ(0) == -100) { /* Treasure Chest Fail Test */
    Player_actor    *pla = (Player_actor *)get_player_actor(game_play);
    
    KAZ(0) = 0;
    /* Secret Set */
    Actor_info_make_actor(&game_play->actor_info,
                  (Game *)game_play,
                  En_Clear_Tag,
                  pla->actor.world.position.x,
                  pla->actor.world.position.y + 100.0f,
                  pla->actor.world.position.z,
                  0,
                  0,
                  0,
                  1);
    }
#endif    

As it suggests, setting KAZ00 (RK00) to -100 spawns an Arwing above the player, then rolls the value back around to 0.

Removed Map Events

Ocarina of Time has a complex story and a big map to traverse. As such, the game contains a map pointer system to help guide players to their next objective and mark where they've already been. After achieving certain objectives, a flashing dot appears on the world map to show where one should go. A static dot appears on the map once a location has been visited. The code in z_kaleido_scope.c that handles these functions contains several areas with commented-out cases that preserve old story events.

Events in red were removed during development.

Camera Modes

The file data/camera.zdb has an early list of cameras at the top of it. It's missing some entries compared to the presumably final list found in the camera_mode enum in src/camera_param_data.h.

As the order of the early list doesn't perfectly match the final list, it has been adjusted to better compare the two, with its original order indicated in the # column.

Lifemeter Environmental Behavior

Commented out code inside the file z_parameter.c utilizes three unused leftover functions of z_lifemeter.c, which would change the behavior of the lifemeter according to Link's environmental conditions, like being in hot rooms or underwater.

////////extern int initial_LifeRestChange_Damage( Game_play * );
////////extern void initial_LifeRestChange( Game_play * );
////////extern int  LifeRestChange( Game_play * );

////////    if ( count >= 0 ) {
////////	initial_LifeRestChange( game_play );
////////    } else {
////////	if ( player_condition == 1 || player_condition == 2 ) {
////////	    initial_LifeRestChange_Damage( game_play );
////////	}
////////    }

////////    if ( player_condition == 1 || player_condition == 2 ) {
	if ( EVENT_FG >= Event_MD3 ) {
	    if ( !(KALEIDO_SCOPE_Pause_on_off( game_play )) &&
		 !message->msg_mode &&
		 !bitcheck( player->action2, P_ACTION2_OKARINA_REQUEST_OK ) &&
		 !game_play->fade_direction &&
		 !game_play->fbdemo_wipe_mode &&
		 !Game_play_demo_mode_check( game_play ) ) {
////////		LifeRestChange( game_play );
	    }
	}
////////    } else {
////////	initial_LifeRestChange( game_play );
////////    }

The unused lifemeter functions inside z_parameter.c temporarily deplete Link's hearts while he is exposed to these conditions. In the case of taking damage or if the temporary heart count reaches zero, the hearts would be permanently depleted, otherwise the original heart count is completely restored.

The lifemeter was also meant to change its visual appearance according to these conditions with different color values still being left unused in the final game. This visual change can be observed in pre-release footage.

Hot Room	Underwater

Curiously, the commented out code doesn't account for the case of Link floating underwater yet, so it only engages when Link is touching the ground with the Iron Boots equipped. The count used to decrease a single heart indicates that the environmental hazard timer was originally double the length compared to the final version.

Drained Spiritual Stones

Commented out code inside z_kaleido_scope.c would render the individual Spiritual Stones colorless inside the Quest Status screen when Link is adult and the related event flags for clearing the first three adult dungeons haven't been set yet.

# if 0
	SetSegmentK0( ICON_ITEM_24_SEGMENT, kscope->icon_item24Segment );
	for ( i = 0; i < 3; i++ ) {	/* 精霊石輝きチェック */
	    if ( ZCommon_LinkAgeIsAdult() ) {
		if ( !Get_Event_Chk_Inf( 4, check_bit[8+i] ) ) {
		    black_white_data( (unsigned int *)SEGMENT_TO_KSEG0(item_data[H_holystone_1+i]), (24*24) );
		}
	    }
	}
# endif

"精霊石輝きチェック" translates to "Spiritual Stone Sparkle Check".

This removed detail refers to cut events where Adult Link would have to restore the Spiritual Stones before the Door of Time would open again. View the unused Temple of Time cutscenes for more details.

Empty Chest Markers

The file z_map_mark.h includes an commented out #define and enum constant for "KARABAKO":

enum {
    NON_MARK = -1,
    MK_TAKARABAKO = 0,
    MK_BOSS = 1,
    MK_KARABAKO = 2,
    MAX_MARKKIND
};

#define	MARK_Takarabako	{ h_dm_box_txt, G_IM_FMT_RGBA, CUSTOM_G_IM_SIZ_16b, 8, 8, 32, 32, 1024, 1024 }
#define	MARK_Boss	{ h_dm_boss_txt, G_IM_FMT_IA, CUSTOM_G_IM_SIZ_8b, 8, 8, 32, 32, 1024, 1024 }
/*#define	MARK_Karabako	{ h_dm_empty_txt, G_IM_FMT_IA, CUSTOM_G_IM_SIZ_8b, 8, 8, 32, 32, 1024, 1024 }*/

"TAKARABAKO" means "treasure chest" and "KARABAKO" translates to "empty chest", which indicates that already opened chests would have been drawn to the dungeon minimaps with their own texture called h_dm_empty_txt, a feature that can be seen in pre-release footage.

Pause Dungeon Map Colors

The file z_map_exp.h includes commented out color values for the dungeon map display, which would render visited rooms in a slightly different shade of blue and highlight the current room in red instead of cyan. The red color can barely be spotted in footage of the E3 1998 demo.

////////#define MAP_COLOR	0x52bf
////////#define LINK_MAP	0xf801
#define MAP_COLOR	0x02bf
#define LINK_MAP	0x0663

        message->fc_b = 30; /*0;*/

Early Bombchu Bowling/Shooting Gallery Interface

//		if ( !(game_play->bow_game_flag >= 2 || game_play->bomchu_game_flag > 0) ) {
		    count_display_rectangle( game_play, 0, parameter->b_alpha );
//		}
	    }

The code to draw the separate counter for Bombchu Bowling and Shooting Gallery seen in pre-release screenshots for the game is commented out in the code of z_parameter.c.

File Select

Skybox & Color Change

The file z_file_choose.c from the attic folder includes a commented out function called frame_color_change and a removed part inside the function cursor_color_change:

    XREG(95) = 255;		//                        （Night）
# endif

These differences would change the skybox and the color values of the visual elements as time moves on, the developers later made the decision to only use the night settings:

Music

To do: Volunteers with keen ears can help determine what is causing the byte differences in particular tracks.

They're not new masterpieces from Koji Kondo, but near-final music sequences exist in z_ocarina/data/ZeldaAudio_music.o. Rather than having new melodies, small differences can be heard in the notes of a few tracks. These are very close to the final sequences used in z_ocarina/data/lib/ZeldaAudio_music.o.

Water Temple

Around 0:39 in the track, the dulcimer seems to be louder and more staccato.

Insights from Mdebug Text

Object files contain names of particular functions in the ".mdebug" portion of the ".o" file. These names originate from the original ".c" scripts that aren't included in the z_ocarina source, but can still yield insight.

To do: For those inclined, there are likely many insights derived from these mdebug files.

Princess Ruto's Kiss

The cutscene that follows Link completing Jabu Jabu's Belly is known as "CRYST". In the final game, once Link and Ruto teleport back outside, Link is startled when seeing Ruto staring into him. The mdebug file labels this scene action for Ruto leaning as "CRYST_MAIN_KISS". It's not clear from the cutscene that Ruto is trying to kiss him, but this action may have once been more evident. Located in "z_ocarina/src/rom_f/z_en_ru1.o".

Lodgenet Gateway Build Info

To do: Thoroughly research all references to GATEWAY_VERSION.

Lodgenet was a service predominately used in North America that allowed hotel guests to play Nintendo 64 games from their rooms. Each game featured on Lodgenet had to follow a list of guidelines to be published to the service, namely remove the ability to save and remove multiplayer features (as can be seen in this Star Fox 64 video). The Ocarina of Time Gateway version is technically the only released version of OoT that has yet to be documented and analyzed. Thanks to build information found in the source listed as GATEWAY_VERSION, it offers insight of what was included in this undocumented build.

Here is a function to clear the saves for Lodgenet usersː

    ZCommonSet( Kenjya_no,    0 );
    ZCommonSet( next_zelda_time, 0xffff );
    ZCommonSet( game_info.next_walk, 0 );

According to the section "ロムヘッダ定義（仮）" (ROM Header Definition (Temporary)) in GNUmakefile,v the initialization for the PAL Gateway version is NZLL, while the default Gateway version is CZLG. In comparison, the codes for the other versions of the final game are CZLJ (Japan), CZLE (North America), and NZLP (PAL).
