on the new Xbox 360 Arcade can we play regular xbox games on it? becuase i read and tried to play them and you couldnt because the drive wasn't compatible or something. do I need to update?
Unless you get a hard drive, you can't play them. Most games for xbox rely heavily on disk caching, as there is always a hdd in an original xbox. It seems that MS would rather you have most things compatible and buy a hdd than only have a few titles possible to play.
