An old mainframe game, ported to GNU Pascal.
The original source is found here: https://github.com/PDP-10/sri-nic/blob/master/files/src/games/lugi.pas
This version compiles with GNU Pascal, and it doesn't crash on start-up, but that's about all I have tested.
Differences:
-
I disabled the high score system, since that code was completely non-portable.
-
On the original system, players would not have seen the initialization messages. The game assumed some sort of dump/undump functionality, which modern operating systems do not provide.
Other than that, the code barely required changes.
