Hey There,

As Variation said, check the Ready to Install area, as I know I found a ****-ton of games that were ready to download from the xbox 360 and that are backwards compatible. If that doesn't work, you can always try to fire up an old Xbox 360 of yours (if you still have it) just to see if they are there, and then go back and see if they come up on the Xbox One.

Let us know how things work out.
