Some time back I asked if it was possible to get more than 8 sprites on a single scanline with the Amiga using a copper list. It seems it is quite possible indeed!
Now I am wondering if it is possible to also split the screen horizontally using a copper list? For example, can you change the resolution from lo-res to hi-res at some arbitrary X coordinate?
Also, is it possible to change the scroll registers at an arbitrary X coordinate so that you could scroll two different planes on the same line? For example, think of a Mario Kart type of game where the game was split vertically down the middle of the screen instead of top/bottom.
