'''GEM Font''' is a bitmap font format originally developed for GEM, the Atari ST operating environment. It typically has a *.gft or *.fnt file extension when used in DOS projects. It was incorporated in the Genus Microprogramming graphics library which was used for various DOS games. The DOS version of NeoPaint uses the format for drawing text into bitmaps.

There also appears to be a format with the same extension that has similar looking binary data, but may be something else (I've put a question mark at after the game titles).

'''Ultima I''' is a role-playing game where you play a hero trying to defeat the evil wizard Mondain to save the lands of Lord British. It is the first game in an illustrious series spanning dozens of titles.

Ultima was originally written for the Apple II in 1981, but a DOS port was released in 1987

'''Microsoft Vector Font Format''' stores vector font data. These font files have the same MZ signature as Microsoft executables, but use a *.fon extension. The same file extension and signature is used by [[Microsoft Bitmap Font Format|Microsoft vector fonts]], but the bitmap format is different enough to warrant its own page. The format appears to have been created for Windows 3.0.

Although the font format was designed for Windows, some DOS programs have made us of it over the years. The format was also included in the Windows installer of later DOS games.
