I created an archive of several of the old sites before they went offline. You can see and downloads maps from the dfb archive I have here:
https://archive.novahq.net/dfbarrack...pdb/index.html
Unfortunately, you can't search the archive for specific maps. I debated adding the maps to NovaHQ but the potential for duplicates is too high and I have no way to filter them out. It would be way too much work.
