I have a few questions:
1.Does anything happened if you leave the G25 adapter on for a long time?
2.How do you adjust the degree of rotation for the ps2 games?
3.Can you set the buttons up for GT4?
1. Yes it gets hot just like a laptop adapter I unplug mine when not in use.
2. You can't adjust the degree as far as I know only adjustment is on a PC.
3. Yes use the DFP settings in the options menu to change the default settings.
4. In your other post you said this wheel cost the most check out the Ecci wheels if you want to see how much a high dollar wheel setup is.
Buttons for the wheel and PS3/PS2
Top 4 The black ones
Top-triangle-cancel-reverse(gear to back car up)
Left-square-cancel
Right-circle-E_brake
Bottom 4 buttons The red ones
Far left-no function
Second button-change view
Third-pause-quick exit (replay at end of race) When you win a race with lots of moneys if you hold this button down as money starts to count down this will add money quick.
Fourth-best race line for license test
Buttons on wheel
Left-look back
Right-nitro
D-pad
Same as controller-up,down,left,right-menu use
Also for (during race)
Bottom-look back
Left- look left
Right-look right
To change any of the button functions use the DFP settings in the options menu. I have not used the wheel in photo mode. The only thing you can't do with the wheel is "exit" game. I also never have my controller on during gameplay, I only turn it on to exit the game. The wheel should be in the far left port to work (port 3 also works for the wheel) port 2&4 will not work for wheel.
