Seems that I can forget about a 48 pixel mothership then.
The mothership (it's not animated btw), will constantly travel onscreen
from the left to the right, during normal gameplay. This means I need to
be able to display the Starfield and (if firing) the laser on the same
horizontal lines any given time. So I'll have to try it with a 32 Pixel
sprite, or won't that make that big a difference?

Epyx did the home versions. You'll find everything about Star Fire, when
following the link I provided above.
