        /* All functions are self explanitory, here's a general structure:
         * Header
         * - Info
         * - XDBF Entries (Data entries)
         * - Free space entries (old unused data that can be reused)
         * Entries
         *
         * To comment everything out in GPD's would be useless and repetitive
         *
         * Achievements, Settings, and TitlesPlayed have syncs associated with them.
         * This is used when updating information to the servers without having to
         * constantly update every single item, it would be a bad system, uneffecient.
         * Each syncable NameSpace has a Sync Entry and an Index Record (I don't know
         * why they wouldn't just combine them, maybe it's a spacial issue).  Sync Entry
         * contains the last synced entry and the next sync ID to be used when needing to
         * assign a sync ID.  To update a sync, you just get the next SyncID, assign it to
         * the respected SyncPair in the IndexRecord, move it to the bottom, and increase
         * the next sync by one.  The Xbox checks it and will sync all ID's that are
         * between the last sync and the next sync.  One trick is you have to make sure you
         * order the entries in the header properly. */
