JKSM is a 3DS homebrew application that can backup and restore save files for 3DS cartridges, and 3DS eShop titles (including GB and GBC virtual console). This tutorial will walk you through its installation and usage.
Prerequisites
In order to use JKSM, you will first need access to CFW or Homebrew. A comprehensive guide on how to set up CFW can be found here. If you do not have what you need, you can still use JKSM with homebrew access
Additionally, you will need to possess the patience and ability to read sentences.
Note: Options on screens may look different based on the version of JKSM you're using. I've tried to provide different screenshots, but if it's still slightly different, you're going to have to be flexible and adapt according and choose the most relevant option at that step.
Downloads
The latest version of JKSM can be downloaded from here.
Using CFW
CFW is the preferred way to use JKSM. Install the .cia using your favorite installer.
Then, launch the JKSM app.
Using Homebrew
- Download JKSM.zip, and create a 3ds folder to the root of your 3DS's SD Card (if the 3ds folder doesn't already exist).
- Paste the .3dsx file into the 3ds folder
- Open the homebrew menu using your favorite homebrew entrypoint.
The Steps
0. You only need to perform this step, if you are trying to dump the save of a newly installed game, or if you have never used JKSM before.
Open JKSM and Select Reload Titles / Refresh Games.
1. Open JKSM on your 3DS and click on Titles.
2. Scroll down to and click on your desired game.
Note: You may need to perform Step 0 if you don't see your desired title listed.
In this example, we'll be selecting Pokémon Sun
