[A83] Re: Sprites with clipping
If you want the sprites to scroll vertically, I'm guessing you don't want
the sprites to disapear once parts of them go offscreen, yes? Of course,
since you're asking for a clipping routine. But you might also consider
making a 80x12 byte buffer and writing a modified version of fastcopy to
only display the middle of the buffer and leave the top and bottom 8x12
bytes alone. These parts would be where the excess 8x8 sprites scroll into
then dissapear. The only problem would be the buffer would take up 960
bytes, but if you're going for speed I would say go with that.
