The space invaders program was among the first I wrote, 
and the TIM/GsSPRITE code probably isn't general.

The later demos that Definitely work with 4, 8 and 16 bit TIMs
(and provide functions to directly link to sprites)
are 2d1, 2d2, and the 2d routines found in tunelfin
and ninth\modules-ninth.

Probably best to rip out the later routines and use those
with the invaders main shell.
