3DS

This guide will show you how to access your server from a 3DS console.

Optional: dumping BOSS keys

You may now dump the BOSS keys from your console for use in the BOSS (SpotPass) server. These keys are only required if you want to create new 3DS SpotPass content.

These steps are based on the guide from the boss-crypto repository.

1. Download the Citra key dumper GodMode9 script and run it in GodMode9. Then, copy the SD:/gm9/aes_keys.txt file from your SD card to the console-files directory in this repo.
2. Run ./scripts/get-boss-keys.sh to validate the dumped keys. It will show you if the keys are missing or incorrect.
3. If it reports that the Wii U BOSS keys are valid, run ./scripts/setup-environment.sh to reconfigure the servers with the BOSS keys.

Connecting

warning

Due to the 3DS's account system, using a local Pretendo Network server with it requires making some potentially dangerous modifications to the system save data.

Create a NAND backup before proceeding.

1. Follow the official Pretendo Network 3DS installation guide to install the patches. At this point, you should be connected to the official Pretendo Network server.

2. Open System Settings => Internet Settings => Connection Settings => (Your current internet connection) => Change Settings.

3. Go to Proxy Settings => Yes => Detailed Setup. Set the proxy server to your server's IP address and the port to 8080. Then, tap OK => Don't Use Authentication.

4. Save the settings and go back to the Home Menu. Check your mitmproxy logs at 127.0.0.1:8081 to verify that the console is sending HTTP requests through your proxy.

   • If you open the Friends List now, you will get a message that "This device's access to online services has been restricted by Nintendo." Your 3DS is not banned. This is expected. The console is trying to log into your local Pretendo server using a NEX account (from the official Pretendo server) that doesn't exist in your local server's database. This causes that misleading error message.

5. Start ftpd on your console and run ./scripts/upload-3ds-files.sh to upload the required files to your console.

6. This is the potentially dangerous part that modifies your system save data. As the official Pretendo docs explain, Nimbus works by setting up a second Friends account using a test environment instead of prod. On the first run, it creates this account, and on subsequent runs, it switches to the already-existing test account. Unfortunately, Nimbus cannot create a third test account, but what you can do is back up the save data for the Friends and account system modules and then reset the test account.

   Credits

   Trace (@traceentertains on Discord) created a modified version of Nimbus that resets the Friends test environment (originally released on the Pretendo Network Discord server as manual_override.3dsx). All credit for the Friends test account reset program goes to Trace.

   1. Reboot into GodMode9 and open the scripts menu.
   2. Run the FriendsAccountSwitcher script and select "Create a new save slot". Name the slot something descriptive like pretendo_official.
   3. Reboot into the Home Menu and open the Homebrew Launcher. From there, run the ResetFriendsTestAccount.3dsx app and press A after a white line appears at the top of the screen.
   4. Open the Friend List applet. You should be "online" and have a new friend code that is different from your friend code on the official servers. If you don't go online, you have not successfully connected to your self-hosted server. Check your mitmproxy logs at 127.0.0.1:8081.
   5. Reboot into GodMode9, run the FriendsAccountSwitcher script again, and select "Create a new save slot". Name the slot something descriptive like local_server.
   6. You now have multiple test Friends accounts saved on your SD card at SD:/gm9/out/friends_accounts/. You can switch between them by running the FriendsAccountSwitcher script, selecting "Load a save slot", and following the instructions.

7. Open System Settings using your local_server Friends test account and create a new PNID or sign in to one you created on your Wii U or website.

How does this work?

The Friends Account Switcher script simply implements "save slots" for the Friends and account system modules, similarly to what Checkpoint does for games.

Each of your Friends saves contains both your prod (Nintendo) and test (Pretendo) account data, as well as a config that determines which account is currently active. So, your pretendo_official slot contains your Nintendo prod friends account, your official Pretendo test account, and a config that makes the test account active. Your local_server slot contains the same prod account but a different test account, and with the config making the test account active. (The account sysmodule save data works in a similar way.)

Note that if you save a slot while Nimbus is set to Nintendo, your save slot's config will be set to making the prod account active. You can switch it back to Pretendo by using Nimbus again. It is recommended to use the pretendo_official slot when using your NNID to keep things consistent with your NNID save data, but either will work.
