I don't know how to switch the superstar type while i'm playing the game in the PC.
In the PS2 i'm just pressing the R3 button but how i'm doing it in the computer?
If you have a PC gamepad with two analog sticks, the method is the same. Check your controller configuration to make sure the right analog button has been assigned.
By the way, this has been discussed at length in the NBA Live 07 General section so if you need any further help, please search for one of those topics. Thanks.
