I would like to play two quests that were done in ZC 1.90 (DOS). I cannot get that ZC program to work in my PC. Before I have tried later versions on some older quests only to have some enemies much stronger than was intended. Apparantly unlike most software, The ZC versions are not backward compatable. Please let me know if I can use one such as "The 184 player" without wasting my time trying. One of these quests is on your most downloaded list. If indeed these older quests cannot be played why are they still available for download?
