Use Your Xperia Play GamePad On the OnLive Service With OnLive Helper
Xperia Play owners who want to be able to use the gamepad to play games using the OnLive Service should check out OnLive Helper by XDA Senior Member hatcyl.
The app should however work with any phone (not just the Xperia Play) and users can create their own custom profiles or use community created ones.
No root is required, and to enable the app, you must change the Input Method Service to ‘OnLive Helper’. Users can have the input method screen automatically come up when opening or closing the keyboard by checking ‘Auto Prompt’ in the options.
