I'm assuming you read through the suggested reading from the lobby announcment: http://www.softwarespecialties.com/cgi-bin/rpgforum/dcboard.cgi?az=read_announcements... and that doesn't help. I have never used DosBox, or abandonware versions, so may not be of much help either. I know the saved game files, under normal circumstances, can just be copied to and fro, and even emailed and saved across versions (like Mac version -> emailed -> downloaded on Windows .. edited -> emailed back to Mac) ... so woudl think that if you can find where ever it is your saved games files are located, and just copy them from Bane to CODS, then CODS might be able to import from there?
Same with CODS -> Wiz 8 ... copy saved game from CODS to folder where saves are stored in Wiz 8.
