The SaveDongle for 3DS works well.
The handling is very simple and extracting/installing savegames is totally smoothly.
I had no problems and I'm happy, that I could now backup my saves.

I never asked for one because they wanted a promise that I would write a review, something I had no intention of doing. I don't believe I needed one either, I haven't had a corrupted save on a real cart in years.

As expected, I’m really impressed with the features of SaveDongle by the R4i-SDHC company. It proved itself be very useful when it comes to NDS Devices. These days, Flash Carts are being banned in countries and rendered useless in every NDS firmware upgrade, but this revolutionary device takes things into the next level.

The SaveDongle has software to read and write save files of DS, DSi and 3DS games which allows the user to back-up his/her save files with ease, edit save files, and importantly share the game files with other players. This product is for every Nintendo gamer to have as it is very useful for them in having the full enjoyment, fun and satisfaction the game has to offer.

This is the first time such a tool becomes available to the mass market, and it's Christmas season. So hopefully things will develop brightly for this tool.

For this time, I don’t see anything wrong with the tool yet, not that I am expecting any as this product is already close to perfect. I will further use it for testing my other game carts and will contact the R4i-SDHC Team about anything regarding the tool/device.
