Functions to emulate the video hardware of the machine. Functions to emulate the video hardware of the machine.
Bullet vs tilemap offsets are correct when compared with PCB videos
(both playfield area, and radar area). Bullet vs sprite offsets are also
correct.
The radar area is offset by 3 pixels, also confirmed with PCB video when
it does the VRAM check.
