|Signature||4 Bytes||0x10 0x00 0x00 0x00|
|BPP Mode||1 Byte||This tells what bit mode the graphics is in. 0x08 signifies 4bpp, 0x09 signifies 8bpp, 0x02 signifies 16 bpp, and 0x03 signifies 24 bpp mode.|
|Reserved||3 Bytes||0x00 0x00 0x00|
|Palette Info||12+ Bytes||Only present for bit modes less than 16.|
|Length of the CLUT Data||4 Bytes||
This is the length of the CLUT Data + 12 (accounting for 12 bytes before the CLUT Data starts).|
It should equal: Number of Colors in CLUT * Number of CLUTs * 2 + 0xC
|Palette Org X||2 Bytes||X coordinate in frame buffer.|
|Palette Org Y||2 Bytes||Y coordinate in frame buffer.|
|Number of Colors in CLUT||2 Bytes||Depends on the BPP Mode. The value for 4 bpp is 16, and for 8 bpp is 256.|
|Number of CLUTs||2 Bytes||This is the number of CLUT groupings.|
|CLUT Data||Number of CLUTs * Number of Colors in CLUT * 2|
|Image Info||12+ Bytes||Present for all modes.|
|Length of the Image Data||4 Bytes||
This is the length of the Image Data + 12 (accounting for 12 bytes before Image Data starts).|
It should equal: Image Width * 2 * Image Height + 0xC
|Image Org X||2 Bytes||Frame buffer X coordinate.|
|Image Org Y||2 Bytes||Frame buffer Y coordinate.|
|Image Width||2 Bytes||* See below|
|Image Height||2 Bytes||This is the height of the image in pixels.|
|Image Data||Varies||Contains data on all the pixels in the image.|
* Note: To get the actual Width, you must multiply the number by either 4 in 4bpp, 2 in 8bpp, 1 in 16bpp, or 1.5 in 24bpp mode to get it in terms of Pixels.
Each CLUT entry is 2 Bytes and all the colors are stored in the order TBGR (Transparency, Blue, Green, and Red). The Transparency bit is only 1 bit, while the others are 5 bits each.
Note: For the CLUT Date in 4bpp, there are 16 Colors per CLUT, 32 bytes per CLUT. In 8bpp, there are 256 Colors per CLUT, 512 bytes per CLUT.
4 bpp mode: Each byte contains 2 pixels (4 bits per pixel). Each 4 bits is a numeric refernce to the CLUT Data.
8 bpp mode: Each byte contains 1 pixel (8 bits per pixel). Each byte is a numeric refernce to the CLUT Data.
16 bpp mode: Each 2 bytes contain 1 pixel (16 bits per pixel) which is in the same format as the CLUT itself.
24 bpp mode: Each 3 bytes contain 1 pixel (24 bytes per pixel). It is the same as the CLUT except each color is 1 byte instead of 5 bits.
