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. | ||
Therefore, ScummVM has to include fonts for the various versions of the two affected games (Maniac Mansion and Zak McKracken).
