Blitter Question
I found out how to do it, and what I was doing wrong! When you write to potgo,
you must doit it at top of frame (WaitTOF()), then read it at the bottom of the
screen. If you don't read it twice, it will wrap around during the next
vertical retrace. Well, I guess thats the right way 😉 It's working for me so
far…
