Just thought id point out that this is the normal D1 GP game, not the 'D1 GP 2005' version that comes out in october, with all the new cars eg the impreza and NOB's Altezza. more info here : http://www.yukes.co.jp/d1-game2005/?
the first ones still a cracking game though, well worth it
2 pieces are very easy to install, the 3rd one is quite tricky, the alternate solution for the 3rd one is to open the slim PS2 and put a sticky tape on the sensor that check if the cover is opened or not
