For this code, you need two VMU's and two controllers. The first VMU should have your main saved game on it, with all the stuff you've worked your butt off to get. Copy this file to the second VMU. Go to two player races and select pink slip race. Select the car you want to copy for players so that you are racing the same car. Complete the race, and make sure player one wins. Now, when it asks player one to save, go ahead and save, but when it asks player two to save, keep pressing B until you get back to the main menu. Load player one's file, and you will have two of the desired car. Then look at player two's file, and presto! The car that you copied is still there. Now you have three of that car rather than two.
