Try the mod from here:
Run DAVEHACK.EXE in dosbox.
If you are a modder and want to decompile the game, here is the Ghidra ( ghidra-sre.org ) project containing information I have been able to gather so far (the first being an import from 2014-03-13):
Download the latest .grb file, run Ghidra and select “File – Restore Project”. Happy hacking!
