Australian iPhone developer and accessory manufacturer 22Moo posted an updated render of its GameBone, its accessory designed to attach to an iPhone/iPod Touch and add console-style controls with a physical directional pad and real buttons (the new photo now shows only four face buttons, leaving out the two shoulder buttons visible in the previous render).

The GameBone's new design also features a 2000mAh battery for additional power, an LED to show charging state and capcity, start/select buttons, built-in stereo speakers, a 3.5mm headphone jack, and an omni-directional microphone. The accessory now attaches to the handset instead of using a Bluetooth wireless controller setup.

The controller won't automatically work with every game, as developers will need to incorporate GameBone into their titles first, but developer Manomio has already pledged support for the pad. Manomio's releases include Flashback for iPhone, the Commodore 64 emulator app, and an upcoming Amiga emulator app.

22Moo plans to release the GameBone in the fourth quarter of 2010. The company plans to make the GameBone software development kit available for free to all iPhone SDK developers who want work with an alternative to cumbersome virtual joysticks in April 2010.
