Totally cool for its time codewise and without using the syncscroll technique.

Try arrow keys.

Very nice looking intro. Too bad there's no music.

Yeah, all JMP demos were only small sized prg files with coderporn inside, without music :)

Maybe they never had any rastertime left to add music? :D

I guess he just didn't care :)

JMP = John M Phillips by the way, the guy who made the games Nebulus and Eliminator (code, music and gfx).

Ah right, I knew I read that name somewhere back then. :)

Yeah, afair JMP was written all over the intro page of Nebulus or in the hall of fame, don't remember exactly :)

Didn't he make a very early demo containing sampled music and a 2bitplane scroller too? Anyway very nice effect, I had to think for a while, even when looking at the code, to figure out how he made the scroll. (And Eliminator is a is a nice game too from a coding point of view, if I remember correctly)

(A note to non-atari people, the ST is barely able to copy a full screen of data with the cpu in full framerate, it takes at least 85% cpu. The scrolling with overhead to update all 16 screenbuffers needed to do a smooth horizontal scroll plus the sprites would be impossible if no clever tricks were used)

Well done! 4bpp in 1 frame.
But 16 screen buffers won't work in a 520ST, with double buffering won't work in a 1040ST !
