At $119.99 on eBay, this Xbox 360 controller “has been modded specifically for Street Fighter 4; all you do is hold down one of the extra buttons to do special moves.” Video after the break. Auction page.

For this controller i have the left extra button programmed for Down, Right, Punch ( Ryu’s Fireball, Sagat’s fireball, etc). I have the right extra button programmed for Down, Left, Punch ( same as left button but for opposite side).
