This is a dos game and hence it need the old gameport to get this to work, except if you are not using a dosbox or such emulator which might can emulate your joystick using USB. The configuration if I remember correct was done in a sepeate config which game in the game.
Otherwice it a cool dos game, but mostly placed II of this serie, which it was that game, I started to use Invert-Y in all 3d games and have do that since.
