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.
Press[F4] [F4] [F1] [F10] at the credits screen.
A sound will confirm correct code entry.
