Yup, there is a thread about this on AA:

Hm, I'm not sure. Technically this shouldn't be a problem at all (doing 
it in midscreen with PF graphics by enabling the score color mode in 

But the result might look vertically separated if you don't choose the 
colors quite identical.

That's IMO much more promising. You could even generate an extra  RGB tripple 
every three (or maybe for every single!) scanline. Just don't make it too different 
to the previous one. This might improve the quality significantly, but will 
probably require a lot of handprocessing when preparing the data.
