Overworld Areas
This is a subpage of Overworld
See also: Standard Notation
Outdoor areas (also known as the Overworld) come in two flavors: Normal and special. Normal outdoor areas (the Light world and the Dark world) are mirrored 8×8 grids of 512×512-pixel cells for a total of 64 cells and a 4096×4096-pixel area in size. Normal outdoor grid cells can be quadruple in size (1024×1024 pixels), in which case their indices represent their top-left quadrants and the indices for the other three quadrants they occupy do not occur. Special outdoor areas (such as Zora's Domain) are separate individual mini-areas on their own.

Area Index
In WRAM, there is a byte which indicates whether or not the player is currently in an indoor or outdoor area, and when the player is in an outdoor area, there is a word which contains the index of the outdoor area the player is currently in.
- $7E001B[$1]
- 0 while player is outside
- 1 while player is inside
- $7E008A[$2]
- the current area index while player is outside
- invalid while player is inside
Player Coordinates
See also: Player Position
Let A be the current area index, (Px,Py) be the current absolute player coordinates, and (Lx,Ly) be the local coordinates of the player within the current area.
When the player is in the Light world (area index $00..$3F), the player's coordinates originate at the top-left corner of area $00, and the coordinates can be calculated as follows.
Lx = Px - ( A % 8 ) * 512 Ly = Py - ( A / 8 ) * 512
When the player is in the Dark world (area index $40..$7F), the player's coordinates originate at the top-left corner of area $40, and the coordinates can be calculated as follows.
Lx = Px - ( ( A - $40 ) % 8 ) * 512 Ly = Py - ( ( A - $40 ) / 8 ) * 512
When the player is in a special area (area index $80 and up), the player's coordinates originate at the top-left corner of the current special area. There are two special areas: $80 combines the Master Sword area and the area under the bridge east of the player's house, and $81 is Zora's Domain. Local coordinates within the Master Sword area and within Zora's Domain are equal to the absolute coordinates. The player is in the area under the bridge when their X coordinate is 256 or greater, and their local X coordinate is simply their absolute X coordinate minus 256.
The Light World and the Dark World
The Light world and Dark world mirror each other: Any area index in the Light world refers to an area index in the Dark world of the same size and at the same location, except the Dark world index is increased by $40. The following table lists the areas of both worlds by their Light world name for simplicity.

Background
The background is composed of 32×32 blocks. How these blocks are stored is compressed.
Example: aabbaabb ... aabb; Where ## is the ID of the 32×32 block (1 byte)
In the case that aa = 00 and bb = nn, blocks of ID nn will be displayed sequentially. Outside the value of 00, aa produces interesting effects
