Halo 2: Hint - Vertical or Horizontal Splitscreen

In a two-player splitscreen, Halo 2 will automatically change whether it's a verticle or horizontal split, depending on whether your Xbox is in widescreen or normal mode. In widescreen, the screen will split vertically (one screen on the left, one on the right). In normal screen (4:3 aspect ratio), the screen will split horizontally (one screen on top, one on bottom).
