If you search for Gapps for the Nook Color or how to install Google Apps or Android Market you will get some very large Gapps files but everything within these aren’t needed for all devices. In the case of the Nook Color you will not need the full Gapps for example NFC support would be useless and in most cases causes the Nook to bug out on ROM startup since there is no NFC support. You will also notice that the facial recognition unlock is gone as well, since the Nook Color has no camera this could cause issues if turned on.
