Actually, I think that if you use VDP-commands for copying in screen 4 or
lower, it assumes you're using screen 5. So you should adjust the registers.
Assuming the start-adress the patterntable is #1000 and the starting line
is line 2, then the Y-line of the copy should be #1000 / #80=#20 (32) and
the X-position should be err... 2 lines in screen 4, that is 64 bytes=128
pixels in screen 5...
The X-position should in this case be 128.
or so.
I'm not sure about all this, it's all just a guess...
...and I don't think I'm very clear... ah, whatever.
