BRFNT files

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.

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

Multiple blocks:

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

B09 B0A B0B ...

...
