"We will support both digital and disc-based entitlements," says Microsoft.

Microsoft has explained how downloadable content will work for Xbox 360 games played through the Xbox One's backwards compatibility feature. 

According to statements issued to Game Informer, both disc-based and downloaded DLC will be supported for Xbox 360 games. However, since the Xbox 360's game store is not emulated, content cannot be purchased for older games on the Xbox One.

"Right now, Backward Compatibility does not emulate the Xbox 360 store [so] new Xbox 360 games [must] be purchased on your Xbox 360 or via Xbox.com," a representative explained. "DLC will be supported and automatically downloaded to your Xbox One along with supported games. "We will support both digital and disc-based entitlements for Xbox 360 games running on Xbox One ... Provided you own the DLC already, you should be all set once the service launches widely on November 12."

The New Xbox One Experience dashboard update, which also includes the backwards compatibility functionality, will start rolling out worldwide at 12:01am Pacific / 3:01am Eastern today (November 12).

Backwards compatibility support for Xbox 360 titles won't start right away, however, and will instead become available sometime after 12:01pm Pacific / 8pm UK on November 12.
