Worth the long wait for precalc before the animation playback kicks in. =)

It looks like the old discussion got conveniently wiped.

Anyway, nice to see this one. Might be a good enough reason to grab ZX emu for the very first time ever.

@Krill, did you manage to look under the hood how Dalthon is doing that? It's actually quite interesting :)

Didn't try. :) What do you mean, specifically?

I wonder why it 8-ish KB, though, and not significantly smaller than that. Gives me the suspicion that not everything is fully calculated at init-time (but some animation-relevant data coming with the executable already).

Well, he converted each frame into 2d vector data (by hand :), meaning the shapes and the stars coordinates. Then upon runtime, he is drawing the frames with vector lines, filling them up, then making them into 8x8 tiles (!) and storing into upper memory. Finally, the tiled screens are played back :)
