something a bit worrying

I dont know if this is true or not but I heard a rumor that if you use a gameshark or AR MAX etc for gran turismo 4, It could affect the percentage of completion you could get for the game. It may not be true but I just thought it would be good to notify everyone of this.

I used an ARMax to get 100% on a PAL save without problem. So it doesn't stop you getting to 100%.

I used Gameshark and it worked fine.
