I entered the code for buying the car for a dollar and the code of the gt40, which is one of the main cars I want. However, it doesn't work. Any help would be appreciated. Also, what do the different versions of the game mean, and how do you tell which one you have.
NTSC has 2 versions the US and Japanese versions, and then there is PAL, which is like England, and all those other places. To tell which version u have, look at the front of the DVD case and up in the top right, under the black PS2 part, it should say it... Hope that helps
