NBA Live '97

While shooting a freethrow, hold the spacebar and press your SHOOT button.

Run while holding the turbo button straight for the hoop. When you're right in front of the court press the "shoot" button. The style of dunk you do depends on the distance and direction you are from the hoop.

On the "create player" screen put the name of the programers that appear on the last screen, on the credits screen. If you did it correctly, your player will turn into the programer you selected.
