As we all know, Haltmann based Star Dream off of Galactic Nova's blueprints, created by the Ancients of Technology (who banished the Ancients of Magic for fear of their power, resulting in Hyness's death cult, remember?).
The reason for this was to bring back his daughter (who died in the Galactic Nova explosion), and unfortunately for him it failed.
Or DID it????
Susie came back, but until now we didn't know how. Maybe the wish actually worked, but by that time Haltmann was already stir-crazy: bent on bringing back his daughter, who he didn't realize was his secretary.
As for Star Dream's "3...2...1...GO!...FATAL ERROR" attack (did you notice the parallel to Galactic Nova's wish-granting line?), the machine could have glitched out when Susie stole the helmet, preventing it from granting wishes and absorbing Haltmann's soul, acquiring one of its own.
