- The NTSC display is shorter than PAL. Your monitor will need to be
- adjusted to 60Hz to display this correctly.

- Very few (badly written). Most. In that order.

- It think so.

- No. The PAL screen is taller (256 lines instead of 200 for most games!)
- The programmer simply chops off the bottom of the game display when
- running in NTSC mode. I cannot blame him - I do this myself, except I
- always make sure that there is no critical information displayed
- lower than the 200th line of the game screen.
