If you have an Xbox 360 Arcade i don't think it can read old xbox games.
There is no difference! All Xbox 360 games work on all Xbox 360 consoles.
The Xbox 360 Arcade can play the Original Xbox games. Where the newer Xbox 360 can not. On the Arcade you can also download other old games. But sometimes you can do that on the other system.
