Input (dos vga stuff)
i have a couple of questions regarding input:
1) how do i get a faster key input besides getkey()?
2) how do i get the mouse location and stuff?
Any of these questions would be appreciated if you answered...
DOS oooh, old...
For the mouse reading, investigate interrupt 0x33 (or 0x31, I can''t remember which because I haven''t programmed in DOS for years). There are a variety of interrupt calls which return data, and a couple to set a custom mouse callback ISR.
For faster keyboard input, investigate interrupt 0x16, or hook into the Keyboard IRQ with a custom hander...
It''s a bit vague I know, but my inclination to remember DOS programming is a little low...

A little trawling across my HD revealed the following DOS mouse hooking code... I''ve only included fragments and have no idea if it works any more; munge it as you see fit.

You could try inversereality. They''ve got some good tutorials.
