I have two xbox's one in my room and one in the living room. The one in the living room is my main one and has my account on it. The second one is just for times when I want to be alone. I copied some arcade games from my main xbox to a hard drive to be able to play them in the room. I read a warning mentioning no longer being able to unlock achievements, II thought it meant the copied versions not the original version on my main xbox. So now I can't unlock any achievements with these games. I was wondering how I can fix this.
