Blocking Nintendo servers¶
This page will help you set up a method to block all communication with Nintendo. This will stop any updates and reporting to Nintendo, but it will prevent use of the eShop and online games.
Instructions (AMS DNS redirection)¶
You can configure Atmosphère to automatically redirect any requests directed to Nintendo to nothing instead. Documentation about this feature can be found here. The section below will help you set up DNS redirection on your emummc. Note that this will only apply when you are using cfw.
What you need:¶
- emummc.txt
- Atmosphère 0.18.0 or higher
Setup:¶
- Enter RCM and inject the Hekate payload.
- If you use a modchipped Switch, you can simply just turn your Switch on with the Hekate payload renamed to
payload.bin
on the root of your SD.
- If you use a modchipped Switch, you can simply just turn your Switch on with the Hekate payload renamed to
- Navigate to
Tools
>USB Tools
>SD Card
and plug your Switch into your PC via USB. - Enter the
atmosphere
folder. - If it doesn't exist already, create a folder named
hosts
in theatmosphere
folder.- You should end up with the
sd:/atmosphere/hosts
directory.
- You should end up with the
- Copy the
emummc.txt
file into the hosts folder.- If you want to apply the DNS redirection to sysmmc instead of emummc, rename the file to
sysmmc.txt
- If you want to apply the DNS redirection to sysmmc instead of emummc, rename the file to
- Eject the
UMS
device safely from within your computer's operating system and boot into CFW.
Verify functionality
You can verify the functionality of the DNS redirection by booting into emummc (or sysmmc if you applied the config to sys), and powering off after.
A report will be generated in sd:/atmosphere/logs
called dns_mitm_startup.log
. If this starts with the following, the dns redirection is active
Instructions (90DNS)¶
You can add a custom DNS to your WiFi connection that will block all communication with Nintendo's servers. We will be using 90DNS, a community-run custom DNS server. If you prefer, you can run your own DNS server following the instructions on the GitLab repository.
Enter the console's System Settings, and then proceed to the Internet tab. From here:
Setting up a new connection via Wi-Fi¶
Open WiFi networks without a password
Not all WiFi networks require a password to connect. If your network does not use one, you can use the Manual Setup
option, located at the very bottom of the Internet Settings
screen below all other WiFi networks.
- Select your WiFi network from the list of networks.
- Enter an incorrect password that is 8 characters long and press
OK
. - After a few moments of attempting to connect, the console will display a connection error.
- Press
OK
to close the error message. - Press
Close
when it offers to display more details about the error. - When asked if you want to re-enter the password, pick
View Settings
. - Change
DNS Settings
toManual
. - Pick the server that is the closest to your location out of the below chart and enter its
Primary
andSecondary
DNS into your connection settings. - Enter the correct password for your WiFi connection.
-
Save the settings and test the connection.

- Select
Change Settings
. - Pick the server that is the closest to your location out of the below chart and enter its Primary and Secondary DNS into your connection settings.
-
Save the settings and test the connection.
Using homebrew to set 90DNS on all existing WiFi networks¶
- Download switch-90dns-setter and put it in the
/switch
folder. - Launch CFW and open the homebrew menu.
- Launch
90DNS Setter
. - Press X to apply 90DNS to all WiFi networks.
- Press Y to reboot the Switch.
- Check in system settings if networks have a custom DNS applied.
Location | Primary DNS | Secondary DNS |
---|---|---|
Europe (Server located in France) | 163.172.141.219 |
207.246.121.77 |
America (Server located in the USA) | 207.246.121.77 |
163.172.141.219 |
Example for a 90DNS connection with the Europe settings:
Testing if you can reach Nintendo¶
Testing via the eShop (Stock)¶
- Open the eShop. Wait until it either opens or displays an error.
- If it displays "Unable to display page.", you seem to have blocked Nintendo's servers.
Testing via a homebrew app (CFW)¶
- Download the latest release of the 90DNS Tester
- Place the
Switch_90DNS_tester.nro
in theswitch
folder on your SD. - Enter the homebrew menu and run the 90DNS Tester.
- After the test finished it should look similar to the below picture, with every
nintendo
domain being blocked.
