flaws in your own system...
I have never run into too many prblems except when going from a PS2 controler to a different controler my hands get sore quick but I get used to it, then go back to PS2 control and it happens again.........now I just use the PS adapters, the one with the fans is nice but not for shootem up it has a delay I got four with fans we use em for racing.......just got the formula one cars on GT4 once that happens the Race is on very intence and very stratigic, when you play multi link or lan you can have teams and the game is very live.....I love that game the tracks look so real,
