     That's a pretty good general approach. One try at finding the room
number bytes is to save the game in two adjacent rooms (on different
Save disks). If no other changes occur (like your inventory is
unchanged), you could compare Saves for a changed byte.

     Being able to save/restore emu state is such a cool idea that it's
surprising emus like AppleWin do not offer the feature.

     If you have access to a IIgs, you can start Medea from the old
Roger Wagner program SoftSwitch and save game state-- I have saves of
Alternate Reality: Dungeon using this method. Maybe a IIgs emu, like
Bernie, would allow launching 'Medea under SoftSwitch.
