If I were to get the NDS Backup Adapter Plus, I'll be able to copy the save files of my 4th and 5th gen games (which are on actual cartridges and not r4s or something)? And I'll be able to restore them should my games ever corrupt? I also only have 3DS XLs. So I've looked at this thread but just want to clarify some things. I don't currently know of any tools for this but the concept is to retrieve the timestamp from the current SD Card and apply it to the encrypted files on the backup prior to putting the backup card in the system. If there was a way to synchronize these timestamps before the 3DS system accessed the SD Card it would be possible to restore and use older backups of the SD Card with the Pokemon X and Y games. If that timestamp is not in sync the database on the SD Card is updated and apps like Pokemon X and Y will use this to identify tampering. That same timestamp is stored in an app database on the SD Card within that unique folder. The 3DS system stores a timestamp every time the SD Card is accessed. The 'Private' folder is shared by all 3DS systems that use that SD Card. A single 'Private' folder also exists on the SD Card which is used by certain apps. You CANNOT copy the apps and data from one system folder to another because the files are also encrypted with that unique key. You CAN use the same SD Card for multiple 3DS systems and each one will have its own unique folder on that card. I am just as anxious as many other people to find a way to backup the save data for generation 6 games.Įach 3DS system generates a unique key which is used to create a folder on the SD Card and encrypt the apps and data stored in that folder.

This is not a reply to any of the previous posts.

Furthermore, a brand-new key for the data encryption appears to be generated every time an app/game is launched. This may be well established or documented information for the console hacking community: this testing confirms that every 3DS stores data on the system itself relating to the eShop account and the SD card the system is using. This confirms that there is data stored on the actual 3DS system about the SD card being used with the system.įurthermore, I should point out that writing the image to an SD card then plugging the SD card into another 3DS linked to another eShop account will not show any of the applications on the memory card. I will note that if you attempt to use this method to rewind time on your eShop versions of XY you will get an error from the games. The image can be written to another SD card to allow a player to use a different SD card with their system. It is possible to create an image of an SD card used in a Nintendo 3DS. On a similar note, I would also like to share an interesting fact about the eShop versions of the games.
