i had seen the article "The Skinny on NES Scrolling".
some explain in it:
-----------------------------------------------
here are the related registers:
(v) vram address, a.k.a. 2006 which we all know and love. (16 bits)
(t) another temp vram address (16 bits)
(you can really call them 15 bits, the last isn't used)
(x) tile X offset (3 bits)
-----------------------------------------------
but i dont understand that the (x) mean.
it mean:if (x) = 6,all 32 of tiles are offset 6 pixels?if as I said,so the screen is show 250*240 pixel?
