A small update for anyone who may be interested: I've just discovered that it's possible to enable a basic debugging mode which creates several log files:
- Creature.plc
- events.plc
- mapgen.log
- mapplace.plc
- objects.plc
- region.plc
- Section.plc
- Wizard.plc
This is made possible with a very simple EXE patch using a hex editor; simply change the value at offset 0xD59CA from 0x75 to 0x74 and the above files will be created when you start a game and then quit.
Edit: in case it wasn't obvious, the file in question is Chaos.exe
