I was looking over some files to free disk space when I saw this again.
Now that I remember it, I'm doing a remake of the Circle of Death map from RA1. After a hard drive crash, I didn't notice that I never did backup this file and only got the Arctic Circle Redux map.
nice!
I never finished the map for actual detailing, and the map file was lost forever. I don't know if I still want to do this again.
