Owners of an iPhone may have been aware of the Joypad app, a small utility that turns your Apple smartphone into a NES-style control pad, allowing you to play iOS games on your Mac, PC, Apple TV or iPad using your iPhone.
The Joypad team have been working to port their SDK to other iOS devices and have just released a new SDK which allows Apple device owners to - wait for it - play iOS games on their Apple TV via their iPhone and iPad.
The beauty of the Joypad SDK is that it can be incorporated into any iOS game on the App Store, providing application developers with the option to make their games Apple TV compatible with simple code tweaks.
Granted, you will need to own each of these devices but with the magic of Airplay, Joypad extends games played on your iPad to your television - wirelessly - giving you complete control via its iPhone application.
After you download the Joystick app on your iPhone it will connect to the iPad via Bluetooth. Once the connection has been made you can then push the game from your iPad to the Apple TV with Airplay. In effect you'll be using your iPhone as a controller and your iPad as "console".
As of now the catalog of games is relatively small, but with the Joypad SDK any developer can add this capability into their apps.
