DKRDS Palette Bank (File Format)

DKRDS Palette Bank is a nameless file format used in Diddy Kong Racing DS. It contains BGR555 color data used to render pixels from tile sprites. It exists in two variants depending on the bit-depth of the accompanying DKRDS Texture Tileset file: a 16-palette bank (for 4bpp tiles) or a single 256-color palette (for 8bpp tiles). Both variants are exactly 512 bytes. Other filetypes that are commonly associated with palette banks, and necessary to create screen backgrounds, are DKRDS Tile Layout and DKRDS Tilemap. Its type identifier in assets.bin is 0x00.

File Format

The file byte order is always little endian.

Variant A

The first variant is used with 4bpp DKRDS Texture Tileset files. The 512 bytes are divided into 16 palettes of 16 colors each.

Structure

Offset	Type	Description
0x00	UInt16[16]	Palette 0 (colors 0-15).
0x20	UInt16[16]	Palette 1 (colors 0-15).
...	...	...
0x1E0	UInt16[16]	Palette 15 (colors 0-15).

Variant B

The second variant is used with 8bpp DKRDS Texture Tileset files. The 512 bytes form a single palette of 256 colors; pixel bytes index directly into it.

Structure

Offset	Type	Description
0x00	UInt16[256]	BGR555 colors (colors 0-255).

Notes

Color index 0 of any palette is transparent regardless of the stored BGR555 value.
