What do you mean by saving the game progress? All Z-machine implemenations allow you to save your progress. Or are you looking for a a memory dump of the machine? I have just confirmed that Frotz 2.44 under FreeDOS 1.1 in Virtualbox will crash when playing Lost Pig or Uninvited, but not Shadowgate. I have a vague suspicion that the problem might be related to the zcode file size or how memory is provided to the Z-machine VM.

The "FROTZ" that appears in the crash message is from the filename of the executable. If I rename it to FOO.EXE, the crash message will contain "FOO". -- David Griffith dgri...@cs.csubak.edu A: Because it fouls the order in which people normally read text.
