<p>this'll be (relatively) easy to do, since it turns out this program only needs 432 KB, since it targets a 512 KB RAM machine.<br />Since it's no longer 1990, I think I can safely bump that up a bit? I won't need more than another 64 KB, which means I'll just bump the game up to 496 KB memory required. Completely doable in any 640 KB or more machine!</p>
