These are the banners you'll see in various places in the [[System Menu]]. They have the dimension 32x32 pixels.

Languages (in correct order) are: Japanese, English, French, German, Italian, Spanish, ?Chinese?, Korean.

== Animation Sequence ==
The sequence is represented by 2-byte tokens, in the following format (we're now talking bits, from left to right):
{| class="wikitable"
|- style="background-color: #ddd;"
! Length
! Description
! Mask
|-

|-
| 3
| Bitmap Index
| 0x0700
|-
| 8
| Frame Duration (in frames (one frame = 1/60sec))
| 0x00FF
|}
Both bytes being zero indicates the end of the sequence. If the first token is zero, the non-animated default image is shown.

== Bitmap Format ==
The bitmap is tiled 8x8 pixels (Nintendo tends to do this). Each pixel contain 4 bits of data, being the index into the palette specified by the current sequence-token.

== The Palettes ==
Each color in the palette is in the standard 2-byte RGB5551 format (used since GBA).

The conversion to RGB888 is made like this (C):
u8 r = ((color ) & 0x1f)<<3;
u8 g = ((color >> 5) & 0x1f)<<3;
u8 b = ((color >> 10) & 0x1f)<<3;

== Checksums ==
The CRC-output is not bitwise inverted after the calculation, but it is byte-swapped to big-endian. Polynominal used is: 0xA001, same for all.

The file name seems to be stored in the file header 3 times:
*Original file name 0x0066
*Current file name 0x0078
*Partial file name 0x0092

The file name is stored in 3 parts:
*3 hex bytes, the first byte's high nibble is not the same as the first byte of the file name
*13 bytes for the central part of the file name
*2 bytes for the last part of the file name.

For the file name : G35B20_0909841CDBEB1_002

The preview image is a 64x48 image stored in a 16 colour tile way, with each 8x8 tile taking up 32 bytes of the file.

Here's two preview images I (blasty) decoded from some PPM files.
