The V1 and V2 font format is identical to that found in V3 games; the big difference is that in V1 and V2, the font is not stored in the game data files, but rather is hardcoded into the executable. All characters are 8x8 pixels big. | The V1 and V2 font format is identical to that found in V3 games; the big difference is that in V1 and V2, the font is not stored in the game data files, but rather is hardcoded into the executable.

Currently, ScummVM includes fonts for english, french, german, italian and spanish game variants. It is not known whether there were other localizations, but if you encounter any make sure to tell the team about it! | Currently, ScummVM includes fonts for english, french, german, italian and spanish game variants.

After this header the character data starts. Every character in the charset takes up exactly 8 bytes, representing 8x8 pixels in which the actual character is contained (the actual width and height of the char should be computed from the charset header). | After this header the character data starts.

Like all other resources in V5 and later, the charset data is stored in a chunk, in this case a 'CHAR' chunk. The header looks as follows: | Like all other resources in V5 and later, the charset data is stored in a chunk, in this case a 'CHAR' chunk. The header looks as follows: | ||

Observe that this header is identical to the V4 header with a few bytes added to the start of it. The charset format is otherwise identical to the V4 format described above. | Observe that this header is identical to the V4 header with a few bytes added to the start of it.

In V7 and V8 (Dig, FT, Comi), the fonts where stored in separate files with the extension "nut". We thus call the format used in these games the "NUT format". | In V7 and V8 (Dig, FT, Comi), the fonts where stored in separate files with the extension "nut".
