The NES PPU handles not only sprites, but (scrolling) tilemaps as well.
Also, IIRC a lot of the game logic runs off the 50/60Hz vblank interrupt.

But, I get what you're trying to do, and it may actually be possible
with a simple ROM like "Tennis" (no scrolling, few sprites).

I did something very similar with the TRS-80 and the arcade Space
Invaders...<http://members.iinet.net.au/~msmcdoug/sitrs/index.html>
