This is incomplete.

Stores images of characters used to display text. Can be found in Mario Kart Wii and possibly others.

The file structure is composed by a header and sections. There always appears to be a FINF, TGLP and CWDH section along with one or more CMAP sections.

The file is not completely known.

The endianess is Big Endian.

Bitmap is formed in a Zig-zag way.

A single block of bitmap looks like this:

00 01 02 03 04 05 06 07

08 09 0A 0B 0C 0D 0E 0F

10 11 12 13 14 15 16 17

18 19 1A 1B 1C 1D 1E 1F

Multiple blocks:

B01 B02 B03 ... B08 (assume width=64)

B09 B0A B0B ...

...

Multiple images:

I01

I02

I03

...
