If you can't connect to Xbox Live, you need to go here http://www.xbox.com/en-US/games/backward鈥?/a> and follow the directions to download, burn, and install the update to your 360. Double check that your game is on the backwards compatible list here http://www.xbox.com/en-US/games/backward鈥?/a> . also, you must have a hard drive to play backwards compatible games on your 360.How can i get the normal (old) xbox games to play on my xbox360?
