Well, VDC doesn't seem to have empties which is a shame for me. I find the regular map generator generates galaxy's which are a bit too crap (too many low-g poors, U-poors, small singles etc) and GM2 galaxy's which are a bit too good. When i used to play the original game with orange or decent rocks (mostly orange) i found it to be just right!Also if you look for gas giants and asteroids why VDCREG doesn't suit you?
But recently Darquan and i have been working on tweaking some other things in the .exe and found it quite easy to hex the orange mod in to it, so maybe you should only consider a new VDC .exe if others also have this issue...
