Yes, you were asked something along these lines some time ago, in a locked post
However, I would like to add my opinion to this: registry entries are a waste of time, and make moving the game needlessly difficult. Imagine I'm re-installing Windows, as I usually have to do every six or eight months. Instead of simply formatting and re-installing on drive C and then immediately playing again on the untouched drive D, I have to re-install the game.
Dito on a new computer, new motherboard, new hard drive, etc etc.
You said that you find .INI files so very Win 3.1 :D - call it .cfg then. This would also allow us to take this great game along on an USB stick, showing it off to friends.
Ciao,

PS: Should you want some Delphi code for this, I'll gladly write you a little unit, so you don't have to change your code.
