I was wondering if the OP2 mapper that Hacker has made could open OP2Demo map files. I first grab the maps.vol off the demo, and open it with the mapper. I then extract the map files, open them with OP2 mapper, and the suspense... Nothing happens. An error occures. Evidently, the demo maps use a differeing tileset from that of the Release OP2. Because this is so, that means that unless the tile values are manually converted (or manually placed in the mapper) no demo map can be played. The only successfull port of a demo map done was Unsettled Earth, also done by Dynamix.
So!
Can the old mapper, with its primitive tileset knowledge open these map files? I doubt it, but I no longer have the old mapper anyway. So I can't test the theory out.
