I posted my source, have a look. Missiles might not be too useful anyway, since they are always set to display two copies like the players. But you could use the ball instead. That would at least allow one shot per invader row without flickering. You might have to limit the invader shots to come only from the last row of invaders though. > I replace my stores with stores to a RAM address fine... I'm not sure what > you mean. I think you are right. MAybe I'm thinking of some other problem in my code, that I was blaming on the trick, as I wasn't fully understanding it. > 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. Ha, my mighty invaders will eat your tiny little kindergarten-invaders for breakfast. ;-) But hey, I just realized that, if I changed my sprites to six pixels width too, I could shift the last two invaders per row, and display 11 evenly spaced invaders that way. But since the two pixel shifting happens to other sprites too, when you remove some from the formation, this might not work in all situations. Might be worth a try though.
