DKRDS Model is the nameless file format used in Diddy Kong Racing DS that stores models and textures.

File Format

The file byte order is always little endian.

Header

The file starts with a header that is 48 bytes long.

Offset	Type	Description
0x00	Byte[8]	Unknown flags.
0x08	Int32	Number of textures.
0x0C	Byte[16]	Unknown. Padding?
0x1C	Int32	Model Data offset.
0x20	Int32	Texture Group offset.
0x24	Int32	Texture Reference Table offset.
0x28	Int32	Unknown. Always the same value as the texture reference table offset?
0x2C	Int32	Unknown. Sometimes 0, sometimes the size of the entire file?
0x30	End of header

Model Data

TBD

Texture Group

This section starts with a 4-byte header:

Offset	Type	Description
0x00	UInt16	Number of textures.
0x02	UInt16	Unknown.
0x04	End of Texture Group header, start of Texture Entries

Texture Entry

After the texture data header there's an entry for each texture. This entry consists of a 20-byte header followed by the texture data. The textures are referenced in the Texture Reference Table using 4-byte UIDs.

Offset	Type	Description
0x00	Byte[4]	Texture UID. Referenced as is in the Texture Reference Table.
0x04	Int32	Unknown.
0x08	Byte	Texture format: 1 = A3I5 2 = 4-Color Palette 3 = 16-Color Palette 4 = 256-Color Palette 5 = 4x4-Texel Compressed 6 = A5I3 7 = Direct Color
0x09	Byte	Unknown.
0x0A	Byte	Unknown.
0x0B	Byte	Unknown.
0x0C	Byte[4]	Unknown.
0x10	UInt16[2]	Texture dimensions.
0x14	End of Texture Entry header, start of texture data

Texture Reference Table

This section lists each 4-byte texture UID directly, in order.
