Introducing Sudomemo Plus! A way to support Sudomemo while supercharging your experience.

What is Sudomemo Plus?

Sudomemo Plus (or "Plus" for short) is a service that allows you to support us while getting some sweet perks in return. Plus is not a monthly subscription, rather, it is prepaid on a per-day basis. 

What are the perks of having Sudomemo Plus?

Plus perks include:

Flipnote Smoothing: Lines, curves, and edges are smoothed for a more natural look on Sudomemo Theatre. This option can be toggled on or off via the Flipnote options menu in your Flipnote's details page. 


Color Picker when Commenting or Chatting: Spice up your comments and messages with a splash of color! You'll be sure to stand out from the crowd when using this feature. Monochrome comments and messages were so 2018...

Enhanced Audio: It's no secret that the DSi/3DS' microphones aren't that great. With this option, we'll do our best to clean up the audio when your Flipnotes are being viewed on Sudomemo Theatre. This option can be toggled on or off via the Flipnote options menu in your Flipnote's details page.


Download your Comments: Have you made a comment doodle on Sudomemo that you particularly liked? By tapping the timestamp, you can visit the comment's details page to save it to your system as a Flipnote.

  • - Winning a Weekly Topic (you'll get 21 days of Sudomemo Plus each time you win a weekly topic)
  • - Redeeming a ticket and crossing your fingers!


Why does Sudomemo Plus exist?

Sudomemo costs hundreds of dollars per month to run, and most of this money comes out of pocket. With Sudomemo Plus, we can ensure the core features of Sudomemo (such as viewing/uploading Flipnotes, commenting/adding stars on Flipnotes, and chatting with others via the chatrooms) remain free and always accessible. Keep in mind that the features that don't require Plus today will always be free. That is our promise.

Flipnote Audio Recording Techniques

Sonic with a DSi

Recording high quality audio can be quite difficult, but it doesn’t have to be. Here’s a list of our favourite audio recording techniques.


Sock on Mic

This ancient technique still works great today and involves nothing but a sock and an audio source.

You will need:

  • - 1 clean sock
  • - A device capable of outputting audio
  • - Your DSi, 2DS, or 3DS

Here’s how it works:

  1. Grab your console and create a new Flipnote. Fill it with blank pages (depending on how long you want your Flipnote to be).

  2. Head on over to the audio recording screen, once there, grab your sock and place it over the microphone on your console.

    💡 Tip: If you’re unsure where the microphone is on your console, take a look at this fancy image that took way too long to create:

    Microphone locations on various Nintendo consoles

  3. Grab your audio source and place it on the sock, right on top of where the microphone would be.

  4. Play your audio but don’t hit record yet. We need to test for audio clipping.

    💡 What is audio clipping? Audio clipping is a form of distortion. If your audio source is too loud, the audio will distort.

    Adjust the volume of your audio source (if possible) so the waveform shown on the right of the audio recording screen is just below the red section.

  5. Once you’re happy, hit record and that’s it!


Speed 5 to 6

Here’s another excellent method for capturing high quality audio. You can even combine this with the above technique for a home theatre surround sound experience, right on Flipnote Studio*.
*Not really, but almost…

You will need:

  • - .mp3 file of the audio you want to use
  • - Audio editing software (we recommend Audacity)
  • - Your DSi, 2DS, or 3DS

Here’s how it works:

  1. Acquire an .mp3 file of the audio you wish to record and import it into your audio editing software.

    Chrome downloading an audio file

  2. Slow down the audio to 50% speed and save it as a new file. In Audacity, you can achieve this by navigating to Effect > Change Speed.

    Audacity's Change Speed screen

  3. Use the Sock on Mic technique outlined above, but make sure you record the slowed down audio at Speed 5.

  4. Once you’ve finished recording, change your Flipnote's speed to Speed 6, and you’re done!


TRRS AUX (Requires a 2DS or 3DS Console)

Get ready, you’re about to be blown away with this technique. You can even combine it with the Speed 5 to 6 technique for superior sound quality.

You will need:

  • - TRRS AUX Cable (Has to be CTIA TRRS)
  • - A PC or Laptop
  • - A 2DS or 3DS system (this will not work on a DSi system)

Here’s how it works:

  1. Check that you have a compatible cable:

  2. Start off by plugging in the Microphone end of your TRRS AUX cable into the headphone jack of your PC or Laptop. This might work with a phone or tablet, but we’ve not tested this.

  3. Now, plug in the output end of your TRRS AUX cable into your 2DS or 3DS system.

  4. On your computer, play some audio and see if your console picks it up. If successful, you’ll see the waveform moving to the music. If not, check your connections or use a different cable.

    Flipnote Studio receiving audio

    💡 What's going on here? Basically, we’ve tricked our console into thinking our computer is a microphone. Anything (audio wise) we output from the computer will be received by the console.

  5. Adjust the volume on your computer so the audio doesn’t clip. On our system, volume 4 to 6 works best, your mileage may vary, however.

  6. Use the Speed 5 to 6 technique outlined above and hit record. Make sure the slowed down audio is playing from your computer and being received by your console.

  7. Once recorded, un-plug the cable from your console and set the Flipnote’s speed to Speed 6, and that’s it!

Nintendo 3DS & 2DS Setup Guide


🚧 Following this guide will require Custom Firmware (CFW). 
If you do not have CFW, please visit 

ℹ️ This guide is for Flipnote Studio and not Flipnote Studio 3D.

WARNING: Resetting your system or uninstalling Flipnote Studio will cause you to lose access to your Sudomemo account.

Installing Flipnote Studio

Since you’re unable to get Flipnote Studio from the eShop, you’ll need to obtain it via other means: 

1a. If you don’t have a DSi with Flipnote Studio installed, you will need to find a copy of Flipnote Studio for your region elsewhere. Please note that the file must end with .cia.

1b. If you already have a DSi with Flipnote Studio installed, you may follow this guide to extract it from your DSi and convert it to a .cia file:

2. Once you’ve gotten Flipnote Studio as a .cia file, transfer it to your “cias” folder in your 2/3DS’ SD card. If you don’t have this folder, create it in the root of the SD card.

3. Open FBI and navigate to SD > cias > Flipnote Studio.cia > Install and delete CIA. This will install Flipnote Studio to your 3DS’ home screen.

Sudomemo: ISP Information

Shortlink to this article:

Hello! If you've been linked to this article, then you are most likely a support technician at an Internet Service Provider.

Your subscriber is attempting to use a service called Sudomemo, which is a Web community of artists and animators creating content using Flipnote Studio on the Nintendo DSi System. A previous service existed called Flipnote Hatena, but it was shut down in mid-2013. Sudomemo exists to fill the void that it left behind, and provide an outlet for those artists and the people who enjoy their work.

If your subscriber is experiencing issues, then there may be an issue with how your configuration is affecting their ability to connect. In general, Sudomemo has one key difference in how it operates from what you'll see with normal web traffic, a DNS override to briefly change the destination of traffic.

Here is the article that your subscriber followed to get it set up:

For DNS Issues

If your subscriber is having issues with DNS (which can be diagnosed with this tutorial), you may be redirecting DNS queries (UDP traffic to port 53) to your own resolvers.

If this is the case, please either provide your subscriber with instructions on how to disable this behavior, or if you have more fine-grained control at your end, please permit DNS traffic to to pass through uninhibited.


Our DNS service only changes the following few domains: (only in Japan)

After your subscriber connects, the domain used changes to an internal one that normally points at the same place anyway, so it should be indistinguishable from regular traffic after that. If you have anything in place that might interfere with this step, you'll want to make a change to permit this to occur.

We ask that you work together with your subscriber to resolve the issue to the best of your ability. Thank you very much!

Sudomemo Connection Troubleshooting: DNS

If you have Sky Broadband, Comcast, or another ISP that interferes with DNS queries, read this or this and then check out sudomemoDNS after reaching out to your ISP with our ISP Help Guide (shortlink

Sometimes you may run into issues connecting to Sudomemo related to your DNS settings. If you're getting 20110 ("Service for this software has been discontinued."), follow this guide to determine where things are going wrong.

Forenote: Make sure you have your proxy settings disabled.


1. As explained in the setup instructions, make sure you still have your DNS settings set correctly:



 2. Next, go to the main menu and open the Nintendo DSi Browser:



3. Once it's finished loading, visit



5. The screen you get will instruct you what to do next. 

If you made a mistake in your DNS settings, or your ISP is overriding DNS:


If things are configured correctly:


If you reach a red screen, read through the text completely and follow the steps presented in them. If you receive the green screen, you should be good to go!

You might try sudomemoDNS - a simple way to connect to Sudomemo when your Internet Provider is overly restrictive.

Make sure to turn the proxy back on when testing the connection to Sudomemo.

If you still get 20110 when testing after receiving the green screen, feel free to reach out to us, under the Help > Contact Us section in the navigation bar.

How to find your Flipnote Studio ID

1. Tap the wrench  icon in the top-right corner of Flipnote Studio's main menu to open your Settings.


2. Your Flipnote Studio ID will be displayed on the first page of your Settings.
