Seen some posters flying around with instructions on how-to enable developer mode on your Xbox One, and thus enable backwards compatibility with Xbox 360 games? Yeah? Ignore them please. If you hold your shiny (and big) new console dear, you will not do as it says. The poster lists six steps to unlock backwards compatibility, but the only thing that it achieves to do is convert your heavy new console into a heavy and expensive new... paperweight.
So if you see this:
...please ignore it and move on with your life instead.
