<p>Hartie95: Added some more games using the secure Value</p> <hr /> <div>=Summary=<br /> Anti Savegame Restore (internally referred to as ''Save Data Rollback Prevention'') is a feature originally implemented in [[Filesystem_services|FS]] module with [[4.0.0-7]], which prevents the user from restoring previous versions of a savegame image. This feature is not used for gamecard games. When an old version of the save is detected, the application will display an error regarding old savegame version, then delete+recreate the save(similar to when the savegame is corrupted).<br /> <br /> =Implementation=<br /> When creating the SD savedata, the application generates a random u64 value, then stores it in an arbitary savefile in the savegame FS. The application then uses the anti-savegame-restore [[Filesystem_services|FS]] commands to verify the stored u64(with the u64 loaded by FS module), and to update the u64 used by FS module. The u64 used by FS module is stored in the FS module [[System_SaveData]].<br /> <br /> Each time the application writes to the savegame, the u64 value stored in the savefile should be updated(and the command for updating the NAND u64 value should be used as well). Usually applications update this value by incrementing it, however generating a new random-number or other methods of updating it can be used as well.<br /> <br /> =Applications using this feature=<br /> * Animal Crossing: New Leaf<br /> * Pokemon X &amp; Y<br /> * Pokemon Omega ruby &amp; Alpha Saphire<br /> * Pokemon ORAS Demo <br /> * Pokemon Shuffle<br /> * Super Smash Bros<br /> <br /> It's currently unknown whether there's any eShop-only titles that use this.</div>

<p>Hartie95: Added a question about System Data Archives</p> <hr /> <div>Hey Guys,<br /> <br /> Does somebody know how to open the &quot;System Data Archives&quot; like &quot;cver&quot; and &quot;nver&quot;?<br /> I would like to make it possible to check the firmware version that a patch needs in the [https://github.com/hartmannaf/Free-multi-Patcher freeMultiPatcher], and I would like to differ between firmware and kernel Version, because of things like firmlaunch. <br /> Otherwise there could be a wrong interpretation of the for example used home menu.<br /> <br /> And with the possibility to allow the user to add own patch files that will be loaded from the SD in the next update, it would be better to have such mechanisms.</div>
