    I've learned that on very fast machines that still might not work.
If the frame takes very little time to draw, the WAIT won't pause
because the screen could be still in the same vertical retrace. Instead,
use this:

    WAIT &H3DA,8,8
    WAIT &H3DA,8

    This code makes sure that an entire frame is paused..
