Awesome? It's just a classic controller pro, but with a USB adapter for use on PC, Android, etc. Have you never used a Classic controller pro or something?Dang, sounds awesome. Where can I get one of those CCPro adapters?
As for the adapter, it can be bought from a veriety of websites - here's a list of where it's sold
Note however that there is a sequence with how the adapter works. For two controllers you plug in the controllers first, then you plug in the USB adapter. For one controller you plug in the USB adapter first, then the controller.
