Time-Based Lighting

Select areas in the game have lighting that changes depending on the current "world time". Some notes on this:

800F1640 is a byte value that stores an id used to keep certain lighting/skybox settings between scenes:

Id	Purpose
0	Default
1	Cloudy Hyrule Field (from Market as adult)
2	Cloudy Kakariko
3
4
5	Raining in Kakariko and Kakariko Graveyard

Environment Lighting Blending

800F1658 stores an array of five different Environment Lighting Blend settings, each record being 0x2A bytes long. The purpose for each setting is as follows:

Index	Purpose
0	Clear Sky Lighting/Fog, uses environment settings ids 0-3
1	Overcast Sky Lighting/Fog
2
3
4	Kakariko Village / Kakariko Graveyard Rain.

Each 0x2A byte record is subdivided into an array of seven different "time blocks", with the following structure:

0x00 ushort //Start World Time
0x02 ushort //End World Time
0x04 byte  //Environment Setting Index A
0x05 byte  //Environment Setting Index B

The Environment Setting Index refers to the data referenced by the 0x0F scene header command.

Hardcoded Stuff

Save Warping

When reloading from a save, the game checks a byte value that stores the scene number that the game was saved in, in order to determine where to spawn Link. Saving in scenes 0-26? will cause you to spawn in a set location based on a table in code.

U1.0 Notes

800902F0 - Start of the Spawn Entrance Index correction routine. Immediately follows the call that copies the save file
B7EA40 - Jump Table for setting the spawn entrance index on save load. Indexed by the scene number that the file was saved in. 26 entries.
800FC090 - List of Entrance Indexes that are set to 11A5D0 when reloading a save inside a dungeon.

Game Over Warping

Whenever you get game over within a boss room/fight scene, or within one of the the tower collapse scenes, your spawn will be set to the main entrance of the dungeon. Save Context + 0x0000, which stores the current entrance index, is used to determine what location a savewarp should take you to.

Id	Scene	Respawn Scene	Entrance Index
17	Gohma's Boss Room	Deku Tree	0000
18	King Dodongo Boss Room	Dodongo's Cavern	0004
19	Barinade Boss Room	Inside Jabu-Jabu's Belly
20	Phantom Ganon Boss Room	Forest Temple
21	Volvagia Boss Room	Fire Temple
22	Morpha Boss Room	Water Temple	0010
23	Spirit Temple Boss Room	Spirit Temple	00??
24	Bongo Bongo Boss Room	Shadow Temple
25	Ganondorf Boss Room	Ganon's Tower Climb
14	Ganon's Tower Collapse Interior	Ganon's Tower Collapse Exterior
15	Ganon's Tower Collapse Interior (Exit)
26	Ganon's Tower Collapse Exterior
79	Ganon Battle

Tower Collapse Sequence Timer

The timer used in the Tower Collapse sequence is the same one used for the trade items that expire when the player takes too long to deliver them. Outside of the Tower Collapse scenes, this timer behaves like a trade item timer. Inside of the Tower Collapse scenes, the behavior is more complex.

There are two temporary scene flags (0x36 and 0x37) set during Tower Collapse. Temporary switch flag 0x36 determines that the trade timer should warp you to Ganon's tower if it expires, rather than triggering the miniquest failure, while temporary switch flag 0x37 determines that the tower collapse sequence has started. This creates the following outcomes:

0x36	0x37	Result
0	0	If you're in a tower collapse map when a timer expires, it acts as if the trade item timer expired
0	1	You have infinite time to complete tower collapse, timer expiration warps you nowhere
1	0	If your in a tower collapse map, you warp to the top of Ganon's tower but it softlocks because the trade timer is stuck at 0
1	1	Normal tower collapse sequence

Custom Scene Setups

By default, scene setups 0-3 are reserved for combinations of day/night, child/adult. However, there are some hard-coded exceptions:

Scene 81 (Hyrule Field): Setup 0 is used for both day and night versions of Hyrule Field as a child, while setup 1 is used for after Zelda throws the Ocarina of Time, but before it's obtained.
Scene 85 (Kokiri Forest): Setup 2 is used for the Adult version of Kokiri Forest when it has been invaded by monsters, while setup 3 is used for after the Forest Temple has been completed.
Scene 99 (Lon Lon Ranch): Exists, but forget how (think it's the child version?)

Switch Flags

When creating a new save, a permanent switch flag within the Water Temple's set of flags is initialized to a default value, in order to set the dungeon's starting water level.

Zora's Domain Water Box

Function 8004213C (Debug Rom) contains extra logic for enabling one of the water boxes in King Zora's room in Zora's Domain
