iWorld Australia is transforming the iPad into a old-school arcade gaming machine with its latest iON iCade accessory.

Simply dock an iPad into the cabinet and you can wirelessly control games with the integrated joystick and buttons.

The iCade is compatible with 100 Ataris classics like Asteroids, Centipede and Battlezone. All titles are available via an in-app purchase in the free Atari Greatest Hits app. iWorld claims that new and existing apps can also be updated to work with these controls.

Here is a video of the iCade in action:
