Atlas: /* Tools */

'''DKRDS Texture Tileset''' is a nameless file format used in ''[https://en.wikipedia.org/wiki/Diddy_Kong_Racing_DS Diddy Kong Racing DS]''. It stores raw Nintendo DS 8x8 character tile graphics used to build screen backgrounds. It exists in 4bpp (32 bytes per tile) and 8bpp (64 bytes per tile) bit-depth variants, which correspond to different palette modes in the accompanying files. Other filetypes that are commonly associated with texture tilesets, and necessary to create screen backgrounds, are [[DKRDS Tile Layout]], [[DKRDS Tilemap]] and [[DKRDS Palette Bank]]. Its type identifier in [[assets.bin]] is '''0x00'''.

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

== Header ==
The file starts with a 4-byte header.

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Int32 || '''Number of tiles''' ('''T''').
|}

== Tile Entries ==
After the header comes the tile entries. The total file size is always <code>4 + '''T''' x ''size''</code>, where ''size'' is 32 (4bpp) or 64 (8bpp) depending on the variant.

=== Variant A ===
The first variant is used together with a 16-color palette from a [[DKRDS Palette Bank]] file. Each tile is an 8x8 pixel block where every pixel is a 4-bit index (0-15) into one of the 16 available palettes.

==== Tile data layout ====
Each tile is made of 32 bytes. Pixels are packed two per byte, row-major within the tile:

{| class="wikitable"
! Offset !! Description
|-
| <code>'''R''' * 4 + '''C''' / 2</code> || Two pixels from row '''R''': low nibble = pixel at column '''C''' (even), high nibble = pixel at column '''C'''+1 (odd).
|}

=== Variant B ===
The second variant is used together with a 256-color palette from a [[DKRDS Palette Bank]]. Each tile is an 8x8 pixel block where every pixel is a full byte (0-255), a direct index into the single 256-color palette.

==== Tile data layout ====
Each tile is made of 64 bytes. One byte per pixel, row-major.

== Notes ==
* Pixel index 0 is always transparent. The corresponding palette entry may contain any value; it is never displayed.
* Sub-tile IDs referenced from the [[DKRDS Tile Layout]] file are direct indices into this file. For Variant B (48-byte two-section layout), the full value must be used without masking, as sub-tile IDs can exceed 1023.
* The [[DKRDS Tile Layout]] file specifies which palette bank to use for each sub-tile. In 4bpp mode this selects one of 16 palettes (each 16 colors x 2 bytes = 32 bytes). In 8bpp mode the whole 512-byte palette block is treated as a single 256-color palette and the palette ID field is ignored.

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

== 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.

Its type identifier in [[assets.bin]] is '''0x00'''.

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

== Header ==
All variants begin with a 4-byte header.

! Offset !! Type !! Description
|-
| 0x00 || Int32 || '''Number of tiles''' ('''T''').
|-
| 0x04 || colspan=2 {{unknown|End of header}}
|}

== Tile Entries ==
After the header comes the tile entries. The total file size is always <code>4 + '''T''' x ''size''</code>, where ''size'' is 32 or 48 depending on the variant.

=== Variant A ===
The first variant is used when the sub-tiles carry their own palette in each tilemap value (4bpp mode with per-tile palette selection). It contains a single section of 32-byte entries. Each entry describes one 32x32 tile as 16 tilemap references arranged in a 4-column x 4-row grid (row-major, left-to-right then top-to-bottom).

{| class="wikitable"
! Offset !! Type !! Description

==== Sub-tile Entry ====
Each entry is composed of a reference ID and tile attributes. Only up to 1024 different sub-tile references can be defined. 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

|-
| 6-15 || '''Sub-tile ID'''. This is the index into the [[DKRDS Texture Tileset]] file (0-1023).
|}

=== Variant B ===
The second variant is used when palette and flip information is stored separately from the sub-tile references (4bpp or 8bpp mode). The file is divided into two back-to-back sections (32-byte and 16-byte each) rather than interleaved per-entry data.

==== Sub-tile Entry ====
Each entry contains a direct sub-tile reference. The value here is '''only''' a tile index, so up to 65536 different sub-tiles can be referenced in contrast of Variant A's limit of 1024.

{| class="wikitable"
! Bits !! Description
|-
| 0-15 || '''Sub-tile ID'''. This is the index into the [[DKRDS Texture Tileset]] file (0-65535).

== 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.

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