One thing that you should add when you clean up your code are some
instructions that turn on VBLANK at the start of the overscan. If
VBLANK isn't on during the VSYNC lines, you'd get a strange gloom
at the top of the screen. At least on a PAL TV where the displayable
area is bigger than the display of your game you would.
