I'm attempting to play the original Fable on my Xbox 360 console. I have a Pro (white w/ Chrome disk drive) with a 20GB HDD. I had no trouble playing Halo or Halo 2 on this console, but when I try to play Fable, I am greeted with the "This original Xbox game is not supported" dialogue. I've tried all of the steps in the announcement thread about playing original Xbox games on a 360. My system software has been updated to version 2.0.13146.0 via the "Test Xbox LIVE Connection" interface.
Any suggestions would be greatly appreciated. Enjoy your day,
