Because your 3DS XL fit into your pocket too well before, Nintendo is finally releasing the bulky Circle Pad Pro add-on to make the system that much bigger.
This is the first time the Circle Pad Pro peripheral for the 3DS XL is available in North America. The company has it up on its official store for $19.99. It begins shipping tomorrow. The hardware shell adds a second circular analog pad for use in certain games that support dual-analog functionality.
The original 3DS has had a Circle Pad Pro since Resident Evil: Revelations launched in early 2012. Major games like Monster Hunter 3 Ultimate, Metal Gear Solid: Snake Eater 3D, and Kingdom Hearts 3D all support the peripheral.
