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. | 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. | ||

Another minor difference compared to the V3 format is that all characters are exactly 8x8 pixels big. Thus the font is always monospaced, unlike V3 fonts. | Another minor difference compared to the V3 format is that all characters are exactly 8x8 pixels big.

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.
