The R4i Save Dongle is exactly what you would think, it can extract/replace save files on game cartridges. This is specifically why it was built. It is usable with every game cartridge, from DS games to 3DS games. It is able to extract the correct save file in the known format of .sav, which allows it to be recognised by game save editors.
Your R4i Save Dongle will be shipped in a red box, with nothing else apart from the dongle itself. The dongle feels quite sturdy and not all that heavy. It's a bit on the big side, but not too big.

Features that are listed on the back of the box:

User friendly software interface to manage the save file
Lots of Google translate, but the point gets across.
PC Software
The PC software is quite straightforward. It has one button which is used to get the save and another button which is used to write the save. You can download everything you need from here, just scroll down to the app download sector. You need the SaveDongle backup/restore, the Firmware Uploader, the 3DSSaveTool v0.2b and when necessary the drivers.
The upgrade software is relatively simple too. You first need to download a firmware file from the official site. Once you have the latest firmware, upgrading is a breeze. Two buttons do the trick, one on the PC and one on the dongle. Wait for a few seconds then you are done.
Once done with extracting the save, you can upload it to the official site. From this site you can also download saves from others who have uploaded. Picking the correct save is easy-peasy as the saves are tagged correctly, have a short description and are checked by staff of the site.
Cartridge Compatibility
I have tested the Save Dongle with the following games. I tested them by retrieving my own save and putting someone else's save back.
Putting my own save back always worked and restoring saves from flashcarts also works. My tests did however reveal that there seems to be some problems with restoring saves to certain 3DS carts. All the tests were done with update v1.3 and the backup/restore program v1.5.

DS-Scene would like to thank the R4i-SDHC.COM team for sending us the review sample.
A new form of 3DS savefile decryption got introduced with a new 3DS firmware update a few months ago. Unfortunately they can't simply fix it for these 3DS savefiles, it needs to get cracked first.
