Rasterbar Scroll Routine ...
Hello there ...
In the Year 1996 i found in a Disk-Mag a very simple routine for a rasterbar scroll ... Now i have forgotten the code ...

Raster bar scroller? A scroller with rasterbars behind the text? Or an upscroller with rastersplits (like in part 1 of Mixer/Upfront)? |

Still don't get it. So the upscroller shouldn't use any chars, *only* rasterbars (rastersplits)? (like in Mixer by Upfront?)
That is the only way i can imagine you could do an upscroller, with *only* rasterbars and nothing else... (but i'm not 100% sure what kind of upscroller you mean)
(so that the letters isn't made with chars (as they normally are in normal upscrollers), but instead with different colors in the different x-splits)

This is what i understand as rasterbar upscroller:
There are seperate colors on each line, which move upwards.
There is a very simple solution for this, which does not
copy around anything..
- lda $d012
beq -
inx
smod:
lda coltab,x
sta $d020
cpx#lastline
bne -
dec smod+1 ;this is the upscroll part!
The above is just a skeleton, not a working routine!
The colortable at coltab must be there twice, so that
an overflow does not become visible.
