Unzip TRRNSC99.ZIP with " -d " within your main NASCAR 99 directory.  Enter
the game and choose Driver Info.  Select car 11 (Optimistic Fool) from the
left list, and push the triangle that points to the right.

If you already have 39 drivers on the right, you will have to remove one of
those drivers first.  To do so, select a car from the right list, and push
the triangle that points to the left.

Do this for both vehicle types: cars and trucks.

Enjoy the TRR vehicles!  =]
