New page

'''DKRDS Sprite Group''' is the nameless file format used in ''[https://en.wikipedia.org/wiki/Diddy_Kong_Racing_DS Diddy Kong Racing DS]'' that stores a formation of tiles and positions to create sprites. Its type identifier in [[assets.bin]] is '''0x00'''.

== Header ==
The file starts with a header that is 12 bytes long.

{|class=wikitable
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || {{unknown-left|'''Unknown'''. Always 0?}}
|-
| 0x02 || UInt16 || {{unknown-left|'''Unknown'''. Number of sets? Always 1?}}
|-
| 0x04 || Int32 || '''Number of sprites''' in this group to be rendered on the screen.
|-
| 0x08 || Int32 || '''[[#Tile Generator|Tile Generator]] offset'''. Always 0xC?
|-
| 0x0C || colspan=2 {{unknown|End of header, start of Tile Generator}}
|}

== Tile Generator ==
All offsets from here on are always relative to the start of this section.

{|class=wikitable

|-
| 0x00 || UInt16 || '''Number of [[#Tile Set|Tile Sets]]''' ('''S''').
|-
| 0x02 || UInt16 || '''Total number of tile texture blocks'''.
|-
| 0x04 || [[#Tile Set|Tile Set]]['''S'''] || '''Tile set entries''', 8 bytes long each.
|}

=== Tile Set ===
Each tile set links tile information blocks with tile texture data.

{|class=wikitable

|-
| 0x00 || UInt16 || '''[[#Tile Texture Data|Tile Texture Data]] offset'''.
|-
| 0x02 || UInt16 || '''[[#Tile Information Block|Tile Information Block]] offset'''.
|-
| 0x04 || UInt16 || '''Number of tiles''' ('''T''').
|-
| 0x06 || UInt16 || '''Total texture data length''' in bytes, of all tiles in this set.
|}

== Tiles ==
After all tile set entries are defined, each pair of arrays, that is '''T''' tile information blocks, and then its corresponding '''T''' tile texture data chunks; are stored sequentially.

=== Tile Information Block ===
Each information block is 8 bytes long and stores position and tile format data.

|-
| 0x05 || Byte || '''Texture dimensions'''. Only the 4 least significant bits are taken into account:

* 1 = 16x16

* 11 = 32x64

=== Tile Texture Data ===
Texture data is stored as 8x8 blocks in 16-color palette format (4 bits per pixel). Palette data is stored in separate files.
