I've been trying to track down this issue for some time, but can't quite figure it out.
Look at the line below the castle -- looks like I'm changing name tables at the wrong time. I suspect that my NMI/vblank timing is off, but I can't figure out why. In game, I see some other anomolies as well (flickering when entering the first level, or when showing the treasure screen), but it otherwise plays fine.
Has anyone else run into this issue and/or have any advice?
Thanks,
James
