I don't think I explained it well, but its a fundamentally different way of aiming. Think about aiming a pistol, that has physical sights, you're using those sights to line up a target. Now imagine using a wiimote to do the same thing. You can't, so the games have an onscreen cursor you drag around. Lightgun games don't use a cursor, you use the sights on the physical gun.
Wiimote controls are relative, whereas lightgun controls are fixed. Completely different. So as I said, you can use a cursor with emulation to play these games, but it makes them far too easy, as they weren't designed with it in mind.
