Someone, I think Tung Nguyen, updated the DeadCold source to work with the current version of Free Pascal. The older version has a number of problems. Unfortunately, I lost what seems to be my only copy of the source when my hard drive died, and I can't find any of the correspondence I had with him about it (if it was someone other than Tung who did the conversion, sorry for forgetting your correct identity).
I still want to revisit DeadCold, but I don't think it's realistically possible at any time in the near future.
