If you are using a non-fixed font (or not including all the characters listed later in this post), then you need to create a sub images file that defines where, in the main file, each letter is.
The subimages file is named '<font file name> subimages.txt'. Substitute the name of the file that has the font images for '<font file image>' and leave the space in (I hate spaces in the file names, but this is how AppGameKit is set up).
The image file probably should have the characters in the order as follows: space !"#%&'()*+,-./0123456789@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
The subimages file looks something like this:
32:0:0:30:72
33:34:0:19:72
34:68:0:31:72

The first value is the ASCII code for the character. The second is the x offset for the start of the character in the font file. The third is the y offset. The fourth is the width. And the fifth is the height.
If your file does not have the full set of characters, then the subimages file should only have definitions for the one in the actual file.
