I'm not sure the rainbow effect is really there but I think it is
because there's a rainbow line (missle 0) along the left hand side at the
very top of the screen after you press select or on the screen between
rounds (i.e. the mountain screen). I know it's hitting HMM0 around 21
cycles into the scanline but i couldn't get it to produce the star effect.
Maybe there isn't a star effect. I can't verify it since I don't have
a supercharger :-( Anybody know where I can buy one at?
If it's not a star effect you may not be able to see the rainbow line
because of the 8 pixel HMOVE blanks (not sure).
