Yes, I used the same files that are used by other software, based on the ones published by the FFVV and arranged by a friend pilot. On my side, I just adapted the format to SkyDemon. These files overlap well the zones that appear on the official maps, but of course not exactly, but they are bigger, so quite safe.I will be some days far from my computer, so if you want my Custom Data folder, I can send it to you this evening by mail, just send me a mail. The zones will appear on your computer and you can easily compare with OACI map.
