In an ideal world you could have : 32/8 full colour hardware sprites ...16x16 or 8x8 ? with sprite collision detection ? Hardware scroll vertical/horizontal Increase in Colour palette Hardware line interrupts (programmable) to switch palette at a fixed number of scan lines ? No need for CPU intervention.
Even a second Video processor to give superposition, Superimposed video. This could be something like a V9938/V9958. though this obviously would mean quite a bit of extra circuitry, but the resulting graphics would be superb, probably surpassing a Commodore AMIGA. Though this all boils down to someone with the time, brains and means to make it happen !
