===Room Data===
 
====Room Headers====
 
*{{$|027502}} to {{$|027781}} =  Pointer Table, {{hex|2}} byte local addresses, indexed by room ID.
 
*{{$|027781}} to {{$|027FEF}} = Data
 
 
 
<blockquote>
 
Headers are {{$|0E}} (Decimal: 14) bytes formatted thusly:
 
*Byte {{hex|0}}: {{red|aaa}}{{blue|b bb}}{{green|c}}{{purple|d}}
 
**The {{red|a}} bits are transformed into {{hex|0000 0}}{{red|aaa}} and stored to {{$|0414}} ("BG2" in Hyrule Magic)
 
**The {{blue|b}} bits are transformed into {{hex|0000 0}}{{blue|bbb}} and stored to {{$|046C}} ("Collision" in Hyrule Magic)
 
**The {{green|c}} bit is unused
 
**The {{purple|d}} bit is stored to {{$|7EC005}} (If set, use a lights out routine in the room transition)
 
       
 
*Byte {{hex|1}}: {{red|aa}}{{blue|bb bbbb}}
 
**The {{red|a}} bits are unused
 
**The {{blue|b}} bits are transformed into {{blue|bbbb bb}}{{hex|00}}, thus making them a multiple of 4.
 
This value is used to load 4 different palettes for the dungeon, and corresponds to, you guessed it, Palette # in Hyrule Magic!   
 
 
 
The resulting index is used to load values for {{$|0AB6}}, {{$|0AAC}}, {{$|0AAD}}, and {{$|0AAE}}
 
       
 
*Byte {{hex|2}}: gets stored to {{$|0AA2}} (GFX # in Hyrule Magic)
 
*Byte {{hex|3}}: value + #$40 gets stored to {{$|0AA3}} (Sprite GFX # in Hyrule Magic)   
 
*Byte {{hex|4}}: gets stored to {{$|00AD}} ("[[Room Effects|Effect]]" in Hyrule Magic) 
 
*Byte {{hex|5}}: gets stored to {{$|00AE}} ("[[Room Tags|Tag1]]" in Hyrule Magic)
 
*Byte {{hex|6}}: gets stored to {{$|00AF}} ("Tag2" in Hyrule Magic)
 
       
 
These are the planes to use for bytes {{hex|9}} through {{hex|D}}. This determines which
 
BG you appear on, and possibly more.
 
       
 
*Byte {{hex|7}}: {{red|aa}}{{blue|bb}} {{green|cc}}{{purple|dd}}
 
**The {{red|a}} bits are transformed into {{hex|0000 00}}{{red|aa}} and stored to {{$|063F}}
 
**The {{blue|b}} bits are transformed into {{hex|0000 00}}{{blue|bb}} and stored to {{$|063E}}
 
**The {{green|c}} bits are transformed into {{hex|0000 00}}{{green|cc}} and stored to {{$|063D}}
 
**The {{purple|d}} bits are transformed into {{hex|0000 00}}{{purple|dd}} and stored to {{$|063C}}
 
       
 
Note, the only safe values for a plane seem to be {{hex|0}},{{hex|1}}, or {{hex|2}}. Hyrule Magic
 
appears to violate this rule by letting you put {{hex|3}} down, but nothing higher.
 
       
 
*Byte {{hex|8}}: {{red|aaaa aa}}{{blue|bb}}
 
**The {{red|a}} bits are unused
 
**The {{blue|b}} bits are transformed into {{hex|0000 00}}{{blue|bb}} and stored to {{$|0640}}
 
       
 
*Byte {{hex|9}}: stored to {{$|7EC000}} These are all room numbers that you could possibly exit to.
 
*Byte {{hex|A}}: stored to {{$|7EC001}}
 
*Byte {{hex|B}}: stored to {{$|7EC002}}
 
*Byte {{hex|C}}: stored to {{$|7EC003}}
 
*Byte {{hex|D}}: stored to {{$|7EC004}}

====Sprite Data====
 
* {{$|04D62E}} to {{$|04D92E}} = Pointer Table, 2 byte local addresses, indexed by room.
 
* {{$|04D92E}} to {{$|04EC9D}} = Data
 
 
 
<blockquote>
 
Sprite data is formatted thusly:
 
*Byte {{hex|0}}: Stored to {{$|0FB3}}. Corresponds with "Sort Spr" in Hyrule Magic. In a layered room this indicates sprites in the foreground are to be drawn on top of sprites in the background.
 
**Bit {{hex|0}} - If {{hex|0}}, sprites will sort
 
**Bits {{hex|7,6,5,4,3,2,1}} - Unknown, should all be {{hex|1}}
 
After the byte {{hex|0}}, you will see 3 byte clusters that break down thus: 
 
 
 
*Byte {{hex|0}}:
 
**Bits {{hex|4,3,2,1,0}} - Y coordinate (in pixels from the top, starting at {{hex|0}}) of the sprite divided by 16.
 
**Bits {{hex|6,5}} - If these are set, they will be used to generate a subtype, stored to {{$|0E30}}, X.
 
**Bit {{hex|7}} - If set, the sprite is on BG2, if not it's on BG1
 
* Byte {{hex|1}}:
 
** Bits {{hex|4,3,2,1,0}} - X coordinate (in pixels from the far left, starting at {{hex|0}}) of the sprite divided by 16.
 
** Bits {{hex|7,6,5}} - If all these bits are set then this is an Overlord, otherwise it's a normal sprite. If only some of them are set they can be used to generate a subtype, stored at {{$|0E30}}, X
 
* Byte {{hex|2}}: Sprite or Overlord type. If a sprite, this will get loaded into a slot at {{$|0E20}}, X. If an Overlord, will get loaded to {{$|0B00}}, X.
 
   
 
The array is terminated with a byte of {{$|FF}}.
 
</blockquote>
 
 
 
====Object Data====
 
* {{$|0F8000}} to {{$|0F83BF}} = Pointer Table, 3 byte long addresses, indexed by room ID.
 
* {{$|01EBA0}} to {{$|01FFF4}} = Data
 
* {{$|050000}} to {{$|053729}} = Data
 
* {{$|0F8780}} to {{$|0FFF4D}} = Data
 
<blockquote>
 
Byte layout:
 
 
 
* Byte 0: {{red|aaaa}} {{blue|bbbb}}.
 
**The a bits are transformed to {{red|aaaa}}{{hex|0000}} and select the type of empty space to fill in. Hyrule Magic calls this 'Floor 1' - Gets stored to {{$|7E0490}}
 
**The b bits are transformed to {{blue|bbbb}}{{hex|0000}} and are the what Hyrule Magic calls 'Floor 2' - Gets stored to {{$|7E046A}}
 
 
 
* Byte {{hex|1}}: {{red|aaa}}{{blue|b bb}}{{green|c}}{{purple|d}}
 
** The {{red|a}} bits are unused and should not be used
 
** The {{blue|b}} bits determine the room's layout type, ranging from {{hex|0}} to {{hex|7}}.
 
** The {{green|c}} and {{purple|d}} bits are unknown, but I have a feeling it's related to {{$|AA}} and {{$|A9}}
 
 
 
After that the bytes come in {{hex|3}} or {{hex|2}} byte object structures, used by routine {{$|01:88E4}}. Objects are loaded until an object with value {{0x|FFFF}} occurs. If a value {{0x|FFF0}} is loaded, the game will start loading Type 2 objects and will not go back to loading Type 1 objects until it is time to load the next layer. (Layer as in HM, not to be confused with the SNES' Backgrounds.) A value of {{0x|FFFF}} will also terminate the loading of Type 2 objects. The routine immediately terminates if that happens during the loading of either object type.
 
 
 
Type 1 Object structure: (3 bytes):
 
 
 
* Byte {{hex|3}}: Routine to use. If this byte is ≥ {{0x|F8}} and < {{0x|FC}}, then it is a subtype 3 object. If the index is ≥ {{hex|FC}}, it is a subtype 2 object. If not, it is a subtype 1 object.
 
 
 
* Subtype 1 Objects, first and second byte
 
** High Byte: {{brown|yyyy yy}}{{green|cc}}
 
** Low Byte: {{grey|xxxx xx}}{{red|aa}}
 
*** The {{red|a}} bits are stored to {{$|B2}}
 
*** The {{green|c}} bits are stored to {{$|B4}}
 
*** The {{grey|x}} and {{brown|y}} bits are transformed into:  {{hex|000}}{{brown|y yyyy y}}{{grey|xxx xxx}}{{hex|0}} - This is a tilemap address that indexes into {{$|7E2000}} and / or {{$|7E4000}}
 
 
 
Use Byte {{hex|3}} * 2 as an index into the table at {{$|8200}}. This is the routine that is used to draw and otherwise handle the object. Subtype 1 objects have a maximum width and height of 4. Width and height are measured in terms of 32 {{x}} 32 pixels. (⟸ last part is questionable)
 
 
 
*Subtype 2 Objects, 1st, 2nd, & 3rd bytes:
 
** Byte {{hex|3}}: {{white|ff}}{{purple|dd dddd}}
 
** Byte {{hex|2}}:  {{pink|eeee}} {{green|cccc}}
 
** Byte {{hex|1}}: {{red|aaaa aa}}{{blue|bb}}
 
***The {{red|a}} bits are unused, but after all they are the marker for this type of object subtype.
 
***The {{blue|b}}, {{green|c}}, {{pink|e}}, and {{white|f}} bits are transformed into a VRAM tilemap address: {{hex|000}}{{green|c ccc}}{{white|f}} {{white|f}}{{blue|bb}}{{pink|e eee}}{{hex|0}}
 
 
 
Might I add this is one messed up format? The {{purple|d}} bits are used as an index into the table at {{$|8470}}. Since such indices are going to be even, the {{purple|d}} bits are transformed into: {{hex|0000 0000 0}}{{purple|ddd ddd}}{{hex|0}}.
 
 
 
*Subtype 3 Objects
 
**Similar to Subtype 1, with a few small exceptions.
 
**The vram address is calculated the same way. However, {{$|B2}} and {{$|B4}} are not used as length or width dimensions here. The routine that is used is determined as follows:
 
**Take the original index (times two) that a Subtype 1 would have used. AND that with {{0x|000E}}. Then shift left 3 times to produce {{hex|0000 0000 0}}{{pink|eee}} {{hex|0000}}. Then, OR in {{$|B2}} and {{$|B4}} and shift left once, so the final result is: {{hex|0000 0000}} {{pink|eee}}{{red|a a}}{{blue|bb}}{{hex|0}}.
 
**Also, this value indexes into {{$|85F0}} instead of {{$|8200}}.
 
 
 
Type 2 Object Structure: (2 bytes)
 
*High Byte: {{green|cccc cccc}}
 
*Low Byte: {{blue|bbbb}} {{purple|dd}}{{red|aa}}
 
**The {{red|a}} bits form a 2-bit value ({{hex|0000 0}}{{red|aa}}{{hex|0}}) that determines the routine to use for the object. In Hyrule Magic, corresponds to the "direction" of the door.
 
**The {{blue|b}} bits are transformed into {{hex|000}}{{blue|b bbb}}{{hex|0}} and stored to {{$|02}} ⟹ X. Corresponds to "Pos" of door objects in the Hyrule Magic. Note that these range from {{0x|00}} to {{0x|16}} (always even) which if you halve those values is 0 - 11 in decimal. This is easily verifiable in Hyrule Magic.
 
**The {{green|c}} bits are shifted into the lower byte and stored to {{$|04}} ⟹ A and {{$|0A}}. This is later used to grab the tiles used to draw the door and the area below it. In Hyrule Magic, corresponds to "type". Note the type is 1/2 of the number listed here. This is because to avoid using an ASL A command, the {{green|c}} bits are always even.
 
**The {{purple|d}} bits are unused.
 
 
 
Next I'll go into the nitty gritty of the various types (the value of {{$|04}}). Again note that we'll only be dealing with even values {{blue|b}}/{{green|c}} that's what you'll see in the code. To convert between here [as well as the code] and Hyrule Magic, take the hex value here and divide by two. Convert to decimal and that's your Hyrule Magic "type."

{{$|1C}} and {{$|1E}} are unused (and hence could potentially be added.) Notice they are all even numbers.
 
In asm routines these values are divided by two sometimes to provide an index into other arrays.
 
That's why. The definition of a "dungeon" is something with a key, compass, and map.
 
 
 
A value of {{$|FF}} (-1) denotes it doesn't belong to a dungeon.

This is used only when you exit the given room. For example, let's say you enter through a skull doorway in Skullwoods.
 
But that's not really a door way, it's just a set of tiles that are no different from a hole you might create after picking
 
up a big rock. But if you entered from a building door, the game has to know whether to put the door frame when you exit.
 
*1 byte:
 
**{{hex|0}} = no doorway when exiting

<blockquote>
 
1 byte each. A value of {{$|FF}} plays the same music as the overworld screen from which the player entered.

====Entrance Values====
 
*{{$|015C40}} to {{$|015C4D}} = Starting Location Data
 
<blockquote>
 
1 word each. Since the starting locations have to reference an entrance, this is necessary.

==Rooms==
 
Tiles on the underworld maps are referred to as "super-rooms" and can contain 1-4 "sub-rooms."
 
 
 
===Primary Map===
 
The primary underworld map consists of {{$|FF}} (decimal: 256) super-rooms arranged in a {{$|10}} {{x}} {{$|10}} (decimal: 16 {{x}} 16) square.
