So, I got the Sega GT 2002 xbox game and i want to play it on my xbox 360.I checked a compatibillity list of the games. and this game works. it told me i need a hard drive/ So i went and bought a 20gb and the cable because i have a xbox slim. But for some reason it still gives me the error: To play original xbox game you have to attach a xbox 360 hard drive. Any1 help?
