Playing Xbox 360 Games On Two Consoles (360 & Xbox One)

Say you have an Xbox 360 beacon for a game or two and you're on an Xbox One console. If your friends start the game with the beacon on a 360, will your Xbox One console give you a notification when they've started playing the game?

If you're playing one of the backwards compatible 360 games, yes. It's just like you were on a 360. If it's a game that has an Xbox 360 version and an Xbox One version (like Destiny or Call of Duty Black Ops 3, for example), then you won't be able to play
together, as the two consoles use different servers.

If you are referring to Games for windows live games no you cannot play pc titles on the xbox console. Pc games play on pc, Xbox 360 games play on xbox 360 the two are completely different platforms.

Sorry to hear that you are having issues, but I think there is some confusion here.

There are two version for Battlefield 4. A 360 version and an Xbox one version. They are considered two entirely separate games so the game saves will not work between the two.

The 360 version of Battlefield 4 is not Backwards compatible so you would only be able to play the Xbox one version of the game on your new console.

Hope that Helps you understand why you can't use the games save from the 360 for the Xbox one.

No. For two reasons. Blacks Ops and Ghosts are two entirely different games for one. And obviously Xbox One and Xbox 360 are entirely two different consoles.
