I have got an original version of call of duty that I used to play with my old Xbox 360. Now I am trying to play this with my new Xbox 360 slim but it is not playing in the new one. I had tried to run that with the different setting but games didn’t load up at all. But it is running very fine with the older Xbox 360. I really want to play this in my new Xbox 360 slim. So guys any clue, what I need to do now?
