What Gen 6 or 7 Save Dongle type tools are there?

[FlyingFalcon]

I'm looking for something that can allow me to transfer a save file from a cartridge onto the computer, edit it with PkHEX, and then write the edited save back onto the cartridge. 

 

To my knowledge, the Joey-Joebags works for Gen 1-3, and the R4i Save Dongle works for Gen 4 and 5. Is there anything that works for Gen 6/7?

 

thanks!

Gen 6 and 7, I think only some Cyber Gadget Power Tool works, but that works for Japanese games only.

Beyond that, people install homebrew/CFW on their 3DSes, which in turn allows them to use homebrew to dump the saves of their carts or e-shop games alike.
