I just spent 90 minutes on the phone with Xbox support and am still unable to play any of the 7 original games on my system.
The support rep and I went through all the steps listed in this thread (http://forums.xbox.com/xbox_forums/xbox_support/f/8/t/25.aspx). Their conclusion is that the 4GB slim has different BC games than the original Xbox. I also have an original Xbox 360 and was able to play 2 of the games (Fable and KOROT 2: The Sith Lords) on my other Xbox with no problems.
I tried to install the game on the hdd but was not given the option. The hdd did not come with the system, I bought it on Amazon and the Xbox rep guarantees the hdd is an official MS drive (because otherwise the update that we tried would not have worked).
Thank you in advance for any help you can offer.
