LORD 4.07 needs five registration codes, and they could only be bought
from Gameport. Gameport has been unreachable for many years, and no one
has been able to buy a code for more than ten years, so most boards
running 4.07 have been stuck unregistered.
LORDKG makes the codes from your sysop name and BBS name. Run it, then
type the same names and the five codes into LORDCFG. Type the names
exactly the same both times: capitals and spaces change the codes.
There is a DOS version (LORDKG.EXE) and a Python version for Linux,
Windows and macOS, in one zip with the source. It is free software
under the GNU GPL.
