ok, i dont entirely know what you mean... do you mean connecting them to each other, or games? games work fine, and you can connect them to each other fine...
yes
if you mean will an xbox 360 game work on a xbox 360 elite? the answer is that it will. a xbox 360 elite is just a normal xbox but black with some extras like it is black and has a 120 gb hard drive
Yes they should work fine.
yes they work on both xbox 360 arcade and elite
The same way you connect it to a regular Xbox 360.
yes any Xbox plays Xbox games The previous answer (above) is not necessarily true. Yes, Xbox 360 games work on Xbox 360 Elite. However, the original Xbox does not play Xbox 360 games, etc (which is why the previous answer was incorrect). Hope this helps, ~Darkeflare
yes it will
Elite of course.
Elite
Yes they work
xbox original xbox 360 core xbox 360 arcade xbox 360 premium xbox 360 elite xbox 360 super elite
