Microsoft has revealed several new details about how the upcoming Xbox One backwards compatibility feature will work.

During a demonstration today, the company confirmed Xbox One owners will be able to play older titles online with gamers who own an Xbox 360, and also explained a bit more about what functionality the games will have.

The Xbox button on the controller will take you to the soon-to-be-revamped Xbox One home screen, but pressing the View and Menu buttons simultaneously will bring up the old Xbox 360 guide replete with all its features. Screenshots and DVR support are also present.

As for why putting a disc in triggers a download, it was explained the system's design means all games must be partially on the hard drive to run. Also it's worth noting that while this is essentially software emulation, hardware won't be supported so old Rock Band peripherals and the like still won't work.

Finally, as a word of caution, when the system launches this Holiday it'll do so with over 100 titles, but publishers will need to give their permission for games to work. This does raise the question of whether those who've recently released HD Remasters will want to enable it right away but, for now, we'll have to wait and see.

It seems like it would be better just to have a 360.
