Download XBOX 360 controller emulator for PC games? Why do you need an emulator for XBOX 360 Controller for PC games? If you play Grand Theft Auto IV (GTA4) and you do not have any XBOX 360 controller or PS3 controller. Then you will know why I need a XBOX 360 controller emulator. I believe that it is part of the marketing that Microsoft does not support normal PC games controller to work on certain PC games. And these PC games only support XBOX 360 controller. Therefore, you will need to buy a XBOX 360 controller in order to play the games with controller. Else you have to stick with keyboard and mouse. Thanks to Racer_S who made this XBOX 360 controller emulator for PC games. Without Racer_S, I still stuck with keyboard and mouse on Grand Theft Auto IV (GTA4).
