Someone at FRUA & DUNGEON CRAFT Community Forums created two (freeware) automapper utilities for this trilogy. All Seeing Eye for EoB1 and EoB2. All Seeing Eye 3 for EoB3. Links are:

Jonas H's approach is based upon DosBox, neither of the ASE programs will work without the relevant EoB# game being played with DosBox.
There are articles on the trilogy too:
