Double Screen Pixeling compo!

We remind you of the deadline
April 30th 2011.
of our double screen c64pixels.com competition!

Read about the rules further down.
First the compo-prizes!:

First three places win:
Either a T-shirt with the submitted entry printed vertically on it,
or in case of a horizontal arrangement, a cool and leet photo-mug.

The overall winner additionally will be the proud owner of a
personalized (handle printed on it) and unique lasered glas cube!

The coders of the 3 first entries get an original boxed C64 game, that we chose from our collection.

If you code the displayer (remember: double screen)
for your winning entry yourself, you get two prizes of course :)

DA RULEZ:
The theme is "double screen",
horizontally or vertically arranged.

The modes should be multicolor, hires or char picture
and displayable on real c64 with 'RUN'.

- softscroll is recommended

- no enhanced modes
(no interlace, no FLI, NUFLI, etc. - in general no 'CPU'-modes)

* exception: to make up for harsh restrictions on double screen charmode:
multiple charsets are allowed)

(So better grab some coder ;-)

- no previously released pics

So get pixeling people!

If you have remaining question feel free to ask veto or enthusi

char mode allows to use hires and multicolor at the same time. is it allowed?
what about a different $d021 color -lets say every line?

Pretty much answers itself - D021 splits uses timing not connected to the mover and should thus be disallowed. Hires and multicolor is merely the result of the format and should be allowed.

Yes, like twoflower put it.
Except for charmode, only scroll-code is allowed.
And charmode contains hires/mc of course.
Since the latter is fun and underrated, no limits are set on the number of charsets used.
Have fune! :)

I've got a char displayer nearly finished, 2 screens (400px high), hires+multi.
It uses variable raster splits for changing the charsets and screens, also rewrites color RAM.

Common colours:

$d021 (background)
$d022 (col 1)
$d023 (col 2)

Color RAM:

$d800 $0-$7 for hires
$d800 $7-$F for multicolor (but colours are $0-$7)

I will stick the code on github.com soon, just need to finish the converter (from popular image formats GIF/PNG) or...

Do you know any existing converters?

How do you do multicolour bitmap horizontal scroller without VSP? Doublebuffering plus manual bitmap and color RAM copying?
