Absolutely!  My problem is that I shoot for Mars, but end up on the Moon.  I
keep trying to squeeze more into these kernels, and get discouraged when I can't, but I have to realize that something can be made out of either of these relatively easily.

Yes, there will be no problem adding the other player and at least one missle. 
I'll be happy with one missle, because with the number of sprites available,
I could easily use a sprite for a shot (wee! imagine shooting shots that really look like missles instead of just dots!)

I have considered going one step further with this algorithm to further
reduce flicker by using both players, that is, if 2 sprites fall on the
same line, assign the first one player 0 and the second one player 1.  The
ultimate in my opinion would also allow me to set a sprite # as being "no flicker" meaning that even if others fall on the same line, it will never flicker (for the player controlled sprite of course).

I'm thinking of making a 2600 version of Sabotage using this engine.  I think I could really do this game justice, and it is one of my all time favorites.

Not that I know of.
