Im looking for a game pad for my Android tablet which I'll be using for emulation. I'm looking for something that will be cover most retro consoles. I think most pads these days are based off the Xbox 360 pad. Problem is that that button layout on the right is always limited to 4 buttons. However the Sega Genesis and Saturn had 6 buttons. Is there a Bluetooth pad out that which is is like the Xbox layout but with 2 extra buttons on the right?
