I know this question is very spesific question but I know there are some c64 code gurus around here. So, here is my question.

When I try to disable screen using $d011 trick, upper/lower border also opens. I want to do that without opening upper/lower borders. Is it possible?

Hi,

You can disable the screen if you put $0B value into the register $D011.
By setting the register value to $1B you can restore the screen.

I hope this is might help.
