After you completed the game, it will show you your score and at the
 botton it said that if you press F4 F4 F1 F10 at the credits you will
 get a hidden mothership. I tried it and if you sucessfully enter the
 codes there will be a sound. By using this code the picture of the
 mothership become a face when open to collect resources and a smiling
 face when it colected the resources. By the way, by using the Game
 Wizard I found out hex 002B0D8E is for solinite, 002B0D9E for
 crystals, 002B0D96 for asteriods, 002B0D92 for amomalies and 002B0D9A
 for plasma.
