What do I need to make the 360 play compatible Xbox 1 games?
First and foremost, you’ll need the hard disc drive accessory plugged into your Xbox 360 to play old Xbox games. If you’ve bought the 360 Core System – which doesn’t come bundled with the 20GB hard drive – then you’re out of luck (unless you buy the drive as an extra, of course). You’ll also need to download and install an update to your 360. This can be done either by updating through Xbox Live, burning the required file onto a CD or ordering the update disc from Microsoft direct. 4. I’m on Xbox Live. Where do I find the update? To get the update, all you need is to have your 360 connected online and logged into Live. Insert an original Xbox game into the 360’s disc drive, close it, and the update should begin automatically. Being on Xbox Live is the most hassle-free way to make sure you can play Xbox 1 games, as the system should automatically update each time support for new games come out.
