You can still use Wayback machine to download KotOR tool. I used wayback machine to go back to the site today as it was archived in May of 2010. It'd take a bit too long to explain it here through text (and I don't think I could convey the directions in an understandable manner) so you'll have to look at the picture below.
KEY: RED = Place you click after first arriving on the site
YELLOW = Place you click to download
BLUE = Where the file would pop up if you use google chrome
