Very nice color results here. It should really scroll left to right permanently or at least start again directly, when scrolling is over.

Pity i did not spend time on a proper left/right screen plotter (via decompression) hence why only the whole picture is shown once.
Flicker could have been reduced immensely if luma threshold was lower at the expense of less mix colors and more artifacts. None the less, it does not flicker anymore than a ifli pic due to pixel swapping(less in most cases)

this looks extremely well on the 50hz synced TFT connected to chameleon ;) too much flickering on the CRT for my taste though.

Too bad the image doesn't swing back and forth. Again an interesting approach to colors and resolution.

Some info on this entry..

The mode is based on the MCOL-CI which made its debut in the demo 'demolicious'

Rather than treating the image as 320x200 in 16 colors and interlacing this between two mcol images, it concentrates on the color mixing aspect to generate around 70+ colors at 160x200 resolution.
some luma combinations would not normally be permitted due to more flicker, but as each 4x8 pixel block in both fields share the same ink/paper/d800 color, flicker can be reduced even further by interleaving pixels in x and y between each field.
The further advantage in this is that the gfx mode only requires a dd00 toggle and no transfer of color data required at all. (if displaying just the static mcol-ci image)
The scroller does not use VSP, and bitmap is softscrolled. Due to the double buffer requirement, this requires around 36k of screen data to be free. (2 buffers of interlaced 160x200 area). I have used the same routine as was used in the first part of the second disk side of demolicious.
Could have solved this limitation by decompressing strips in realtime ofcourse.

i would like to see this motif more hand-pixelled...guess, it would be really atmospheric :-)

CSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the scene around the commodore 64 computer - the worlds most popular home computer throughout time. Here you can find almost anything which was ever made for the commodore 64, and more is being added every day. As this website is scene related, you can mostly find demos, music and graphics made by the people who made the scene (the sceners), but you can also find a lot of the old classic games here.
