'''DKRDS Tilemap''' is a nameless file format used in ''[https://en.wikipedia.org/wiki/Diddy_Kong_Racing_DS Diddy Kong Racing DS]'' which defines a grid of 32x32 tile cells in order to assemble an image. Each cell in the grid is equivalent to one entry from the accompanying [[DKRDS Tile Layout]] file. Rendering all cells in order (from the top-left to the bottom-right tile) produces the complete image. Other filetypes that are commonly associated with tilemaps, and necessary to create screen backgrounds, are [[DKRDS Texture Tileset]] and [[DKRDS Palette Bank]]. Its type identifier in [[assets.bin]] is '''0x00'''.

= File Format =
The file byte order is always little endian.

== Structure ==
{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''Map width''' in tiles ('''W''').
|-
| 0x02 || UInt16 || '''Map height''' in tiles ('''H''').
|-
| 0x04 || UInt16['''W''']['''H'''] || '''Grid of tile entries''', row-major.
|}

=== Tile Entry ===
Each entry represents a 32x32 tile which contains a reference index and flip attributes. They use the following bit layout:

A A A A B C D D D D D D D D D D
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

{| class="wikitable"
! Bits !! Description
|-
| 0-3 || {{Unknown-left|'''Unknown'''. Always 0?}}
|-
| 4 || '''Flip vertical'''. If 1, it mirrors the 32x32 tile on the Y axis.
|-
| 5 || '''Flip horizontal'''. If 1, it mirrors the 32x32 tile on the X axis.
|-
| 6-15 || '''Tile ID'''. This is the index into the [[DKRDS Tile Layout]] file (0-1023).
|}

== Notes ==
* Tile index 0 typically represents an empty or fully-transparent background tile. In minimaps, large regions surrounding the track consist entirely of index-0 entries.
* The flip fields apply to the rendered 32x32 output of the whole 32x32 tile, '''after''' all 8x8 sub-tiles within it have been composited. They are independent of the per-sub-tile flip flags stored in the [[DKRDS Tile Layout]] file.
