07 because is the first position where COLOR00 do not appear on previous line, but you can change in case.
Not sure I get this, but I guess I can just accept it and come back if something doesn't look right later.

Position near the right edge before the horizontal blank where you do not interact with the previous DMA fetch.
This way you have time to set parameters and colors before the next line, which is located in the vertical middle of the screen.
This sounds good.

You need to change this to your needs.
Will do.


I'll keep your explanations as comments in my code, and I'll probably be back with questions after I get all the other bits plugged in.

Thanks.
