Hmm sorry but they are porting games, once you insert the disk your Xbox One will download a huge chunk of data of the internet were talking 5GB+ for each game.<p>Microsoft also isn&#x27;t hiding it:
&quot;The digital titles that you own and are part of the Back Compat game catalog will automatically show up in the “Ready to Install” section on your Xbox One. For disc-based games that are a part of the Back Compat game catalog, simply insert the disc and the console will begin downloading the game to your hard drive. After the game has finished downloading, you will still need to keep the game disc in the drive to play.&quot;<p><a href="http:&#x2F;&#x2F;www.xbox.com&#x2F;en-US&#x2F;xbox-one&#x2F;backward-compatibility" rel="nofollow">http:&#x2F;&#x2F;www.xbox.com&#x2F;en-US&#x2F;xbox-one&#x2F;backward-compatibility</a><p>Sure they might be downloading the 360 version and then doing the emulation but it&#x27;s much much more likely that they&#x27;ve actually simply ported the game.
