No, sorry I am not the maintainer.
I'm guessing the AIBB.font is internal and probably requested when the default system font is not available or the AIBB.prefs file is missing (It's usually located in the s: directory). Please remember AIBB is really old Software so you should not even attempt to change the default font.
Also, some of the hacked versions found on other sites are not the original distribution version.
