True, but it's possible to rewrite the playfield color registers to
create the appearance of more resolution.  The 6502 runs one clock
cycle for every 3 pixels, so it's possible to create playfield
images that have more complex shapes.  The timing's a nightmare
though - I'm only planning on using the technique to build a pretty
title screen.
