'''BFFNT''' ('''B'''inary ca'''F'''e '''F'''o'''NT''') is a font file format used on [[Wii U]] and the [[Nintendo Switch]].

= File Format =
== Header ==
The file starts with a header which has the following structure:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''File magic'''. Always ''FFNT'' in ASCII.
|-
| 0x04 || UInt16 || {{BOM}}
|-
| 0x06 || UInt16 || '''Size of this header''' in bytes.
|-
| 0x08 || UInt32 || '''[[#Version List|Version number]]'''.
|-
| 0x0C || UInt32 || '''Size of the file''' in bytes.
|-
| 0x10 || UInt16 || '''Number of sections''' stored in the file. There may be multiple [[#Code Map|code maps]] and [[#Character Width|character widths]] inside a file.
|-
| 0x12 || UInt16 || '''Padding'''.
|}

== Font Information ==
The ''FINF'' ('''F'''ont '''INF'''ormation) section stores general information about the font, and it places directly after the [[#Header|header]]. It has the following structure:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''FINF'' in ASCII.
|-
| 0x04 || UInt32 || '''Size of this section''' in bytes.
|-
| 0x08 || Byte || '''Font type'''. 0 = Glyph, 1 = Texture, 2 = Packed texture.
|-
| 0x09 || Byte || '''Font height'''.
|-
| 0x0A || Byte || '''Font width'''.
|-
| 0x0B || Byte || '''Ascent'''.
|-
| 0x0C || Int16 || '''Line feed'''.
|-
| 0x0E || UInt16 || '''Alter character index'''.
|-
| 0x10 || SByte || '''Default left width'''.
|-
| 0x11 || Byte || '''Default glyph width'''.
|-
| 0x12 || Byte || '''Default character width'''.
|-
| 0x13 || Byte || '''Character code'''. 1 = [https://en.wikipedia.org/wiki/Unicode Unicode], 2 = [https://en.wikipedia.org/wiki/Shift_JIS Shift JIS], 3 = [https://en.wikipedia.org/wiki/Windows-1252 CP1252]
|-
| 0x14 || UInt32 || '''[[#Texture Glyph|Texture glyph]] offset'''. Relative to -8.
|-
| 0x18 || UInt32 || '''[[#Code Map|Code map]] offset'''. Relative to -8.
|-
| 0x1C || UInt32 || '''[[#Character Width|Character width]] offset'''. Relative to -8.
|}

== Texture Glyph ==
The ''TGLP'' ('''T'''exture '''GL'''y'''P'''h) section stores the textures used in the font. On [[Wii U]], the image data is stored directly, and on the [[Nintendo Switch]] the images are stored into a [[BNTX]] file, embedded inside the font.

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''TGLP'' in ASCII.
|-
| 0x04 || UInt32 || '''Size of this section''' in bytes.
|-
| 0x08 || Byte || '''Cell width'''.
|-
| 0x09 || Byte || '''Cell height'''.
|-
| 0x0A || Byte || '''Number of image sheets'''. For [[Nintendo Switch]], this is the number of images inside the [[BNTX]] file.
|-
| 0x0B || Byte || '''Maximum character width'''.
|-
| 0x0C || UInt32 || '''Size of one image sheet''' in bytes. For [[Nintendo Switch]], this seems to be size of [[BNTX]] divided by number of images.
|-
| 0x10 || Int16 || '''Baseline position'''.
|-
| 0x12 || UInt16 || '''Image format''', see below. Bit 0x8000 means it's compressed, but it's currently not used. For [[Nintendo Switch]], bit 0x4000 means the tile mode is linear, which means the image data is not swizzled.
|-
| 0x14 || UInt16 || '''Number of rows'''.
|-
| 0x16 || UInt16 || '''Number of lines'''.
|-
| 0x18 || UInt16 || '''Image sheet width'''. Width of the images in pixels.
|-
| 0x1A || UInt16 || '''Image sheet height'''. Height of the images in pixels.
|-
| 0x1C || UInt32 || '''Image data offset''', relative to the start of this file. For [[Wii U]], this points directly to the first image. For [[Nintendo Switch]], this points to the embedded [[BNTX]] file.
|}

=== Image Formats ===
; Wii U
The following image formats are supported on [[Wii U]]:

{| class="wikitable"
|-
! ID !! Type !! Color Space !! Bits Per Pixel (BPP)
|-
| 0x00 || RGBA8 || UNORM || 32
|-
| 0x01 || RGB8 || UNORM || 24
|-
| 0x02 || RGB5A1 || UNORM || 16
|-
| 0x03 || RGB565 || UNORM || 16
|-
| 0x04 || RGBA4 || UNORM || 16
|-
| 0x05 || LA8 || UNORM || 16
|-
| 0x06 || LA4 || UNORM || 8
|-
| 0x07 || A4 || UNORM || 4
|-
| 0x08 || A8 || UNORM || 8
|-
| 0x09 || BC1 || UNORM || 4
|-
| 0x0A || BC2 || UNORM || 8
|-
| 0x0B || BC3 || UNORM || 8
|-
| 0x0C || BC4 || UNORM || 4
|-
| 0x0D || BC5 || UNORM || 8
|-
| 0x0E || RGBA8 || SRGB || 32
|-
| 0x0F || BC1 || SRGB || 4
|-
| 0x10 || BC2 || SRGB || 8
|-
| 0x11 || BC3 || SRGB || 8
|}

; Switch
[[Nintendo Switch]] supports the same formats as [[Wii U]] but adds support for the following formats:

{| class="wikitable"
|-
! ID !! Type !! Color Space !! Bits Per Pixel (BPP)
|-
| 0x12 || BC7 || UNORM || 8
|-
| 0x13 || BC7 || SRGB || 8
|}

== Code Map ==
The ''CMAP'' ('''C'''ode '''MAP''') section maps character codes to [[#Character Width|character widths]]. The section starts with the following structure:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''CMAP'' in ASCII.
|-
| 0x04 || UInt32 || '''Size of this section''' in bytes.
|- bgcolor="#AAFFAA"
| colspan="3" align="center" | '''If [[#Header|version]] ≥ 3.0.0.0'''
|- bgcolor="#DDFFDD"
| 0x08 || UInt32 || '''Character code begin'''. Always 0 for scan, because then this field is unused.
|- bgcolor="#DDFFDD"
| 0x0C || UInt32 || '''Character code end'''. Always 0xFFFFFFFFF for scan, because then this field is unused.
|- bgcolor="#DDFFDD"
| 0x10 || UInt16 || '''Mapping method'''. 0 = Direct, 1 = Table, 2 = Scan
|- bgcolor="#DDFFDD"
| 0x12 || UInt16 || '''Padding'''.
|- bgcolor="#DDFFDD"
| 0x14 || UInt32 || '''Offset to the next [[#Code Map|code map]]''' structure, releative to -8. 0 if there is no following section.
|- bgcolor="#FFAAAA"
| colspan="4" align="center" | '''Else'''
|- bgcolor="#FFDDDD"
| 0x08 || UInt16 || '''Character code begin''' ('''B'''). Always 0 for scan, because then this field is unused.
|- bgcolor="#FFDDDD"
| 0x0A || UInt16 || '''Character code end''' ('''E'''). Always 0xFFFF for scan, because then this field is unused.
|- bgcolor="#FFDDDD"
| 0x0C || UInt16 || '''Mapping method'''. 0 = Direct, 1 = Table, 2 = Scan
|- bgcolor="#FFDDDD"
| 0x0E || UInt16 || '''Padding'''.
|- bgcolor="#FFDDDD"
| 0x10 || UInt32 || '''Offset to the next [[#Code Map|code map]]''' structure, releative to -8. 0 if there is no following section.
|}

What data follows depend on the mapping method.

; Direct
The direct method maps multiple character codes to multiple [[#Width Entry|character width entries]]. The following data is stored:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''[[#Width Entry|Character width entry]] index'''. Index of the first entry which maps to the first character code '''B'''. This method uses '''E''' - '''B''' + 1 [[#Width Entry|character width entries]].
|}

; Table
The table method also maps multiple character codes to multiple [[#Width Entry|character width entries]]. The following data is stored:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16['''E''' - '''B''' + 1] || '''[[#Width Entry|Character width entry]] indices'''. Each index corresponds to one character code, starting at '''B'''.
|}

; Scan
The scan method maps multiple character codes to mutlple [[#Width Entry|character width entries]]. This structure does not use '''B''' and '''E'''. The following data is stored.

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''Number of scan entries'''.
|}

Each entry has the following structure:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || UInt16 || '''Character code'''.
|-
| 0x02 || UInt16 || '''[[#Width Entry|Character width entry]] index'''.
|}

== Character Width ==
The ''CWDH'' ('''C'''haracter '''W'''i'''D'''t'''H''') section controls how the characters are stored in the images. The section starts with the following header:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''. Always ''CWDH'' in ASCII.
|-
| 0x04 || UInt32 || '''Size of this section''' in bytes.
|-
| 0x08 || UInt16 || Global index of the '''first''' [[#Width Entry|width entry]] ('''B''').
|-
| 0x0A || UInt16 || Global index of the '''last''' [[#Width Entry|width entry]] ('''E''').
|-
| 0x0C || UInt32 || '''Offset to the next [[#Character Width|character width]]''' structure, releative to -8. 0 if there is no following section.
|}

=== Width Entry ===
Width entries follow directly after the header. The amount can be calculated with: '''E''' - '''B''' + 1. There will always be at least one entry stored. Each entry has the following structure:

{| class="wikitable"
|-
! Offset !! Type !! Description
|-
| 0x00 || SByte || '''Left width'''. The width of the character's left space.
|-
| 0x01 || Byte || '''Glyph width''' of the character.
|-
| 0x02 || Byte || '''Width''' of the character.
|}
