I have been mucking around with mode 13h for a short while now doing
really simple stuff like scrolleys and such like. But certain things
have come to light.

Like is it impossible to access each plane in turn?
Can you use the set_address_high and set_address_low to pan the screen
around?

Can you use page flipping?

I have the feeling that the answer to all these questions. If so then
why would anyone want to use this mode? My current scrolly is so
processor consuming that I can't do anything else!! 

Should I use Mode X from now on? I believe you can do the above
questions with  this mode, right?

Thanks any help will be much appreciated.
 

Ian.
