ive just started doing this aswell with 2 xboxs. dont bother committing suicide with your dummy xbox just have a pen and papper a count on that . you can stick 1 down on the loading screen. if you were to add up how much time you are wasting commiting suicide with your dummy it will be a lot.
also a question about the saving symbol. i was getting that pop up evertime the dummy xbox quit. then after say about 70 gamesit stopped popping up. does this matter. i jsut quit to dash then started again and it came back.
