The black elite controller will work on any model of xbox 360
yes....all xbox 360 use the same type of hard drive even though some could be 20,60,or 120 gb. To sum it up, xbox 360 hard drives are good with any model of the xbox 360.
Because it is a old Xbox game that you are trying to use on a new model Xbox 360 the Slim does not have the software to run the obsolete game.
No you need XBOX 360 controllers.
The original Xbox controller doesn't work on the 360.
Yes you can.
you don't need too, you can use xbox games on xbox 360
No, the AV cord for an Xbox One does not fit an Xbox 360. The two consoles use different connectors and video output formats. The Xbox One typically uses an HDMI connection, while the Xbox 360 can use either HDMI or a proprietary AV cable, depending on the model. Therefore, the cables are not interchangeable.
sometimes but not always
No, you cannot sync an Xbox One controller to an Xbox 360. The two controllers use different wireless protocols and are not compatible with each other. If you want to use a controller with an Xbox 360, you will need to use a compatible Xbox 360 controller.
yes you can use the xbox 360 controllers on the xbox 360 slim. I use my controllers from my old xbox on my new 360 slim.
You can not play xbox 360 games on an original xbox, however you can play some original xbox games on an xbox 360 console.
