This project has been coded long time ago, in 1993. Basicly that was my attempt to create tools needed to make games, in particular this system is a sprite editor and map editor. All coded in Borland C++ 3.1, some Graphical User Interface has been developed (later ported to 32bit).
There were several version of the system, with first geared up towards
Comic/12 and Commander Keen, all platform style games.
The older version remain in history, source was hacked up many times,
and the only one that is left tuned up for Dune3, my old game project.
I don't think anyone will ever need that. However here is the source: GDS for Dune3
