Everything but the no-shared flag is working right now. Getting no-shared to work properly will take a little more work because right now there's nothing to guarantee that the content records are synced between the TMD and content objects in a title. This means that updating any content in a title will result in the records being out of sync and the written TMD will not match the actual state of the content when it was dumped. To mitigate this, I intend on making the content records in the content struct a reference to the content records in the TMD, so that they are the same object and therefore always in sync.
