The FONT format defines fonts that can be used to display text in-game.
|
To do: Notate differences between different versions of the format. Only Metroid Prime's FONT version is documented at the moment. Character definition structure should be expanded on; there should be a section explaining what each value does, and it should be made more clear which UV coordinate corresponds to which vertex. |
|
This file format needs more research There's some unknowns in the header, and some of the values in the character definition structure should be double-checked. |
Format

Kerning Table
This table is at the end of the file, and defines kerning pairs. It starts with a 32-bit count value and then loops the following structure:
| Offset | Size | Description |
|---|---|---|
| 0x0 | 2 | Character 1 |
| 0x2 | 2 | Character 2 |
| 0x4 | 4 | Kerning adjust |
| 0x8 | End of entry | |
