I've had this SE 4 CD now for at least 5 years. I installed it again and found theres this new deluxe version.
So I have SE 4 D 1.95 installed. All I noticed different so far is a couple new races and ship types.

questions- Can I add additional races and ship types without erasing what's here?

What's the story with spaceship supply? I have always added these to my designs thinking that it was needed. Better to be supplied than not was the thinking. I ran into the first enemy ship of this new game and the enemy ship design had no supply in it. Does that mean my ships have better range with those supplies?
