The documentation on this page was made in collaboration with JK.

Backing up save data using JKSV ​

Instructions: ​

    • Note: If you wish to back up all save data at once, simply press Y while hovering over your user in the sidebar, then proceed by holding A.
  3. Hover over your desired game and press A to select it.
  4. Press A again to create a new save backup
  5. Enter a name for the save data folder containing the save data and press + or OK.
  6. Wait for it to finish backing up your save data.

Restoring save data using JKSV ​

  3. Hover over your desired game and press A to select it.
  4. Hover over the save data folder containing the save data you want to restore and press Y.
  5. Hold the A button to restore the save data, keep holding it until it's finished.

Setting up remote save data backups (Google Drive & WebDAV) ​

JKSV features a functionality that allows you to back up your save data from the JKSV homebrew app directly to Google Drive. The setup for this feature is detailed below.

Note: Throughout this guide, clickable items in screenshots will be highlighted in red.

1. Create a new project ​

  1. Go to Google Cloud Console and click Select a project (top-left corner).

  2. Click New Project (top-right). Name it JKSV. It's fine to leave Organization blank.

  3. Wait for the project to be created, then click Select Project.

2. Enable the Google Drive API ​

  1. Click the Navigation menu (top-left) → APIs & Services → Enabled APIs & Services.

  2. Click + Enable APIs and services, scroll to Google Workspace, select Google Drive API, and click Enable.

3. Create OAuth credentials ​

  1. Go to Credentials → + Create Credentials → OAuth client ID.

  2. Click Configure consent screen.

  3. Click Get started to start configuring Google Auth Platform.

  4. Fill in JKSV for the app name alongside the user support email (the email of the Google account you're currently using) and click Next.

  5. Select External, click Next.

  6. Fill in your own email into the contact information field and click Next.

  7. Click the checkbox to agree to the Google API Services: User Data Policy and click on Continue.

  8. Now, click on Create and it will take you back to the overview. Click on Create OAuth client.

  9. Set the Application Type to TVs and limited input devices, then set the name for the client (can be anything, the name JKSV is used in this guide).

  10. Click on Create and you will end up at the final window for this step, download the JSON file containing the client info for JKSV.

    DANGER

    • Note: Google will not allow you to download this file again after this point!

  11. Rename the downloaded file to client_secret.json and store it somewhere safe.

4. Add yourself as a test user ​

  1. Go to Navigation menu → APIs & Services → OAuth consent screen → Audience.

  2. Click + Add users and add your email.

5. Copying the JSON file to your microSD card ​

Copy the client_secret.json file to: sd:/config/JKSV.

6. Launching JKSV ​

The next time JKSV starts with an internet connection, it will guide you to complete the login process by navigating to https://google.com/device and filling in the code mentioned in the middle of your screen in JKSV.

After the primary setup for Google Drive, you can launch JKSV with an internet connection again and it will give you a notification near the bottom of your screen stating Successfully signed in to Google Drive! if your configuration file was set up correctly. You can now back up and store your save data backups on Google Drive by pressing Zr on any save data backup!

7. (OPTIONAL BONUS STEP!) ​

  1. Make a secure backup of client_secret.json from your microSD card after logging in with JKSV.
    • This is recommended if you plan to share saves between multiple consoles due to Google’s OAuth scope policies.

JKSV features a functionality that allows you to back up your save data from the JKSV homebrew app directly to a WebDAV server. The setup for this feature is detailed below.

Please note that this feature requires you to either sign up for a WebDAV server provider or selfhost your own WebDAV server on your local network.

1. Creating and applying the WebDAV configuration file ​

  1. Create a file named webdav.json and paste the following contents in it:

    {
    "origin": "https://example.com",
    "basepath": "path/to/JKSV",
    "username": "optional",
    "password": "optional"
}

  2. Create a folder named JKSV on your WebDAV server.

    • Note: The folder name doesn't have to be called JKSV. For the sake of this guide, JKSV was used for consistency purposes.

  3. Fill in the origin, basepath, username and password fields, the base path is case sensitive and beginning/trailing slashes should be left out in the origin and basepath fields. Keep the information below in mind.

    • The origin field should always contain the host portion of the WebDAV server you're connecting to.
    • The basepath field should either contain the absolute path to the location of the WebDAV endpoint + folder created in the previous step or you can use an aliased folder.
    • The username and password fields should contain your credentials you use to authenticate with your WebDAV server. These lines can be left out/removed entirely if you do not have authentication set up for your WebDAV server.

    If you need WebDAV configuration examples, unfold the section below.

    WebDAV configuration examples

    Example 1:

    Your WebDAV endpoint is hosted on a local server with IP address 192.168.1.100 with the WebDAV endpoint running at 192.168.1.100/webdav, on which you created the JKSV folder. In this example you do not use any authentication.

    {
    "origin": "http://192.168.1.100",
    "basepath": "webdav/JKSV",
}

    Example 2:

    Your WebDAV endpoint is hosted on a WebDAV server provider at https://app.koofr.net/dav/Koofr, on which you created the JKSV folder. In this example you do use authentication.

    {
    "origin": "https://app.koofr.net",
    "basepath": "dav/Koofr/JKSV",
    "username": "<Koofr email address>",
    "password": "<Generated WebDAV password>"
}

    Example 3:

    Your WebDAV endpoint is hosted on a local server with IP address 192.168.1.100 with the WebDAV endpoint running at 192.168.1.100/webdav, but you have an alias for 192.168.1.100/webdav/JKSV set up so that your endpoint is available on 192.168.1.100/JKSV. In this example you do use authentication.

    {
    "origin": "http://192.168.1.100",
    "basepath": "JKSV",
    "username": "<WebDAV username>",
    "password": "<WebDAV password>"
}

2. Copying the JSON file to your microSD card ​

Copy the webdav.json file to sd:/config/JKSV.

3. Launching JKSV ​

The next time JKSV starts with an internet connection, it will give you a notification near the bottom of your screen stating WebDav successfully started! if your configuration file was set up correctly.

You can now back up and store your save data backups on your WebDAV server by pressing Zr on any save data backup!

Checkpoint ​

Checkpoint is also a save manager. It can be used to back up and restore game saves to your microSD card. It also has the ability to share save data over FTP and WiFi.
