Well, the NES has what, 32 colors total in its palette?  The 2600 has 128,
and it's pretty trivial to have all of them onscreen at once (though you're
limited to a few per scanline.)  It wouldn't surprise me if their chip just
let them simulate more colors by alternating frames (a favorite trick on
the C64, though rarely used in games) but I don't know what NES cartridges
had access to, maybe they could generate their own video somehow.  

Which games had this 'special chip'?  It'd be interesting to see if they
work in the emulators (which to me would indicate the former method.)
