XCM Cross Fire Adapter Mates PS3 Controllers With Your Xbox 360, For Some ReasonS

This seems to violate every fanboy code ever written across the hallowed halls of the gaming internet, but if you must use your wireless PS3 controllers to play Xbox 360 games, this is for you.

It also connects wired 360 controllers, as well as your non-360 Xbox controllers, if you must have the heft and fattness of the original. You'll have to drop $85 for the privilege. [Product Page @ Extreme Mods]
