Whoops! I think you mean *320*x200, not 360x200 for screens 7 and 13.
Also, screen mode 13h supports higher resolutions using ModeX, but that's
a different thing entirely.

Two somewhat petty corrections. :-)
No. 1. Screen modes 7, 8, 9, and 12 are 16 color modes. That means that
you can use colors 0-15 not 1-15.
Also. Screen mode 13h allows 256 colors, so you aren't limited to colors
0-15, but rather you have colors 0-255.
