scrolling with $d011

Hi! .. I made a nice working screen scroller from the bottom to the top of the screen. It worked fine and looked good in VICE thet is .. BUT when i tested the code at my c64c it did don't work properly... Chars disapering and whole linse invisible...

I used default screen adress ( $0400 ), and copied the default font from rom to ram ( as hardware reference manual told me ), and pointed vic to the new char adress.

What could be wrong ?

Quote: @itch: You live in Lund, right? So do I... I might have C64c "motherboard" to spare for 50 SEK or so if you need it a lot. (I will keep the SID though, but you should be able to use the one you have in your machine right now.)

Yes :) .. Thanx for the offer, but i have a load of old non working c64's (all different flaws), so i pass this offer :)

50 SEK .. Hmmm .. you'll get a complete c64c for around 200 sek at tradera, so 50 SEK for just the motherboard it a fairly good price i think.

Just calculated it; 5,50 euros (or almost 9 aussie dollahs).
