I guess what I'm trying to ask is......is there any software that will let me play downloaded dlc with my xkey? I know in the past you couldn't. "The tool also has the ability to manage arcade games / DLC and unlock them for use if required."

Can anyone tell me more about 360mpgui? I have an xk3y and I'm wondering what I can do with it. Particularly get dlc. Thanks so much
