Sweet, thank you for offer Are you able to find a file format structure ? If you have a спам time, can you look at .TDF files ? every map has own .tdf file, it probably stands for "Terrain definition file", and it includes a information about map and sectors.
If you want to help with that, I can give you a more information about that....
I currently don't know very much about any of the world ed files, but if you could provide me with some information to start, I could give it a try. I won't have much time today, but I can try from tomorrow on.
