For those part-time programmers out there who may be interested in developing GFF manipulation utilities for KotOR and other Bioware GFF formatted files, I've released an ActiveX component which may be of interest to you.
Once you have run the installer, the ActiveX component, gff_ctrl.dll, will be copied to your System32 folder and registered. You may then begin using it as a Reference (listed as "GFF Object Factory"). Documentation, a sample VB6 application, and an uninstaller are also provided for your convenience. You have permission to redistribute this .dll with any utility you make so long as you retain my copyright notice in both your source code and in any documentation you produce.
I may also release other file manipulators for ERF/RIM/BIFs if there is any interest.
