RE: A85: NASRWarp acting strangely
Yes, I am adding (PROGRAM_ADDR) to the location. Even if I didn't, though,
random pixels would still show up in the correct place on the screen, but
they don't. They always appear in two rows in the lower left corner.
Occasionally two small rows also appear in the lower center of the screen,
at the same height as the ones in the lower left.

If you are using ZShell, are you adding (PROGRAM_ADDR) to the address of
your Sprite? And if you're using Usgard, are you putting the ampersand in
(i.e. ld hl,&Sprite)?
