For Geeky Mobile Gaming: G-Pad Physical Controller for iPhones
The awesome thing about smartphones is that they’re so smart, you can run emulators on ‘em and play your favorite console games anytime, anywhere–without the console. For example, the Game Boy emulator. Some of these games aren’t easy to play with on-screen controls, so it’s a good thing that you can add physical controls with the G-Pad.
It’s a silicone sleeve that you can slide over the simulated, on-screen controls so you can play with controls that you can actually feel instead of having to merely imagine them. It is a lot of fun!
