Does the scroll counters increase or are they modified in anyway when the PPU is off ($2001.3 and .4 both on zero) ?
If not, could the scrolling be normally easily set via $2005, with the screen off the first few scanline, then be turned on later and the scroll value set trough $2005 would be intact (without having to deal with $2006 as usually do midframe) with the vertical value of course added to the number of additonnal scanline that were off ? Or would the scroll be altered ?
