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.

RFNT Header 10h bytes

0000: 'RFNT'

0004: FE FF 01 04

0008: DWORD length of whole file

000C: WORD ??

000E: WORD ?? (language flag?)

FINF Header 20H bytes:

0000: 'FINF'

0004: DWORD finf size

0008: BYTE ??

0009: BYTE font height - 1

000A: WORD ??

000C: BYTE ??

000D: BYTE character width or height + 1 (?)

000E: BYTE character height or width + 1 (?)

000F: BYTE 00 (?)

0010: DWORD TGLP section position

0014: DWORD CWDH section position

0018: DWORD CMAP section position

001C: BYTE font height - 1 (excluding left line?)

001D: BYTE font width - 1 (excluding bottom line?)

001E: BYTE character width or height - 1 (?)

001F: BYTE 00 (?)

TGLP Header 30h bytes

0000: 'TGLP'

0004: DWORD length of 'TGLP' section

0008: BYTE font width - 1

0009: BYTE font height - 1

000A: BYTE character width - 1

000B: BYTE character height - 1

000C: DWORD length of 1 image

0010: WORD images count

0012: WORD ??

0014: WORD characters per row

0016: WORD characters per column

0018: WORD width of image

001A: WORD height of image

001C: DWORD position of data

TGLP Data 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

...

CWDH Section 0000: 'CWDH'

0004: DWORD length of this section

0008: DWORD last character ? (= character count - 1)

000C: DWORD first character ? (= 0)

0010: character count * (

BYTE space width ? BYTE character width BYTE smaller than character width ) ????: (0~3) * 00 (align to 4 bytes)

CMAP Section Type 1 :

0000: ‘CMAP’

0004: DWORD length of this section

0008: WORD UTF-16 code of first char

000A: WORD UTF-16 code of last char

000C: DWORD 0 ?

0010: DWORD position of next CMAP + 8

0014: WORD offset of first char

0016: WORD ?

Type 2 :

0000: ‘CMAP’

0004: DWORD length of this section

0008: WORD 0

000A: WORD -1

000C: 00 02 00 00 ?

0010: DWORD position of next CMAP + 8 (0 if no next)

0014: WORD characters in this table (tbl_char count)

0016: tbl_char count * (

WORD UTF-16 code of char WORD offset of char ) ????: WORD 0
