/* 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. */
