Dolphin is a software application designed to emulate the environment of the Nintendo Gamecube and Nintendo Wii video consoles so games designed for these consoles can be played on a PC. Though the Dolphin emulator currently only supports Gamecube and Wii games, it can be configured to work on a PS3 dual shock controller following the installation of the correct drivers on your computer.
Download, install and run the PS3 driver for a PC.
Connect the small end of your USB cable to the PS3 controller and the other end to the computer. Wait for the device to register.
Click on the "Driver Manager" tab. Select the radio button next to your PS3 device name and click "Load driver."
Click the "Home" icon in the top left corner. Click the radio button next to "PlayStation 3" underneath "Mode."
Press the "PS" button on your PS3 controller to activate it on your computer.
Open Dolphin and click on the "Config" icon. Click on the "Plugins" tab.
Click on the drop-down box next to "Pad" and select your driver name, "MotionJoy."
Click on the "Pad' icon in the main window of the Dolphin emulator. Click the drop-down box next to "Controller" in the "Controller 1" tab. Select "Motion Joy USB game controller."
Click on the "Open" icon. Navigate to a Gamecube or Wii game, highlight it with your mouse and click "Open."
Use your PS3 controller as usual.
