Not one to let sleeping dogs lie..... I did some more tweaking....

we now have sound and motion....

and choppiness in the sound is due to video capture software

code and various files available at:

sooo.... we did a "little" more tweaking here....

this is a whole sg24 screen !!! (6K) in less than 2 frames.... total speed demon...

thanks to sixxie & sorchard for helping me out here....

enjoy

well.... post away....

alot of stuff could probably be precalced to reduce the overhead.....

/Simon

well now stew.... if we want any more speed out of this baby, we are gonna have to unroll it even further.... in which case we lose the DP, question is, will the increased speed be better than a "semi unrolled" looped DP routine...... well, on the c64 we had a tendancy to unroll the whole thing........

what i will do "though" is point you all to an error that wasn't part of the original code..... alot of ppl won't notice it as it runs fast and looks nice... but if you study the attached file, you can see that the LSB/MSB should be swapped in certain situations..... ok.... sixxie sorted that out......

see.. this makes me happy happy happy !!!!

I knew my c64 background in demos would prove useful on the coco/dragon....

cheers guys !!

BRILLIANT !!

Glad to see you took to the plasma routine and recooked some stuff for more speed....

/Simon

btw....

let me know if you want the chessboard source......

/Simon

@captain nemo.... chessboard is pretty good... (took alot of attempts) the right hand sideborder is "piece of cake"... just requires very careful timing.... and don't go to far or the screen freaks out..... the basic idea would be shift from a 16 to 32 byte mode on a per line basis to fool the vdg's...

it's just an old c64 routine that i ported to the coco II.....

lots more "funkies" to come......

here is a quick vid:
