From what people have said here, you have to get a mod chip for your PS2. I was going to buy one through a guy here but the thought of taking my PS2 apart and changing stuff kinda worried me. I don't want to screw it up. And then the chip is like $30 plus S/H, the game is $25 plus S/H, so you just paid $70 or so to play a game that has a whole 30 or so cars. I think its sorta worth it, as news of another new Japan only GT is comeing out soon. I don't know, it's a risky deal. You have to find GTC, the Chip, and maybe the new GT on the web, and if it's an individual, you have to deal with a stranger with your money. I don't know man...
