Wow.. that code is eerily similar to mine. Although I put mine at the top
of RAM and you put yours at the bottom. :) My code is able to do a
load/store for missiles, although I'm not quite sure how to make that
useful... I posted my source, have a look.

I replace my stores with stores to a RAM address fine... I'm not sure what
you mean.

Your invaders are all ugly blobs, mine are much better :) I've also got
single-pixel precision for the positioning, although yours replicates the
way the original moves one row at a time rather than the entire formation.
