Well I just got GT4 yesterday. I played it for the first time today. I hooked my DFP up. You know the wire you have to plug into the PS2? Well when I plug the DFP wire into the PS2, it only works on the top outlet. Its hard to explain...... You know the 2 rectangle shape outlets southwest of the Controller 1 slot? When I plug my DFP to the bottom one I get nothing. The wheel still does the little self adjustment while the game is loading, but when I press the buttons I get no response. No respones from the d-pad(the one on the DFP) or the the other buttons on the DFP.
But when I plug my DFP to the top outlet thingy everything works fine. This happened to me when I tried playing GT3 with the DFP. It is wierd how it only works if I plug it into the top one.
When I play Nascar Thunder 2004, I plug it into the bottom one and it works fine. But on GT3 or GT4, I get no response. Its not a problem because I can still play GT4 fine if I plug it into the top outlet thingy.
Does anyone else get this problem?
