You need a capture card and streaming software to show 3DS gameplay on PC

The Nintendo 3DS does not have built-in streaming to a computer. To get 3DS video and audio into your PC, you must physically connect the handheld to a capture card — a device that converts the 3DS video signal into data your PC can record or broadcast. The 3DS outputs video through its cartridge slot or HDMI (depending on the model), and the capture card sits between the 3DS and your PC via USB.

Once the video reaches your PC, you use streaming software like OBS Studio or Streamlabs to display it on screen, adjust the layout, add overlays, and send it to platforms like Twitch or YouTube. The whole setup costs between $30 and $150 depending on capture card quality, and takes about 20 minutes to connect and configure.

Key Takeaways

  • A capture card is the only way to get 3DS video into your PC; the handheld has no native streaming feature.
  • The Elgato HD60 S+ and AVerMedia Live Gamer Portable 2 Plus are the most common capture cards used for 3DS streaming.
  • OBS Studio is free, open-source software that works with any capture card and runs on Windows, Mac, and Linux.
  • The 3DS outputs video at 240p resolution, which is lower than modern games but acceptable for casual streaming and recording.
  • You will need a USB 3.0 port on your PC and enough disk space to store video files, or bandwidth to stream live.

Which capture cards work with the 3DS

Not all capture cards accept 3DS input. The 3DS outputs composite video (red, white, yellow cables) or component video (red, green, blue), not HDMI. You need a card that has composite or component inputs, or an adapter that converts 3DS output to HDMI before the card receives it.

The Elgato HD60 S+ is the most popular choice for 3DS streamers. It accepts HDMI input, so you must use a composite-to-HDMI converter (around $15 to $25) between the 3DS and the card. The card itself costs roughly $150 and connects to your PC via USB 3.0. It records up to 1080p video, though the 3DS will only send 240p, so the extra capacity is useful if you later stream other consoles.

The AVerMedia Live Gamer Portable 2 Plus costs about $100 and also requires an HDMI input, so again you need a converter. It is lighter and more portable than the Elgato, which matters if you plan to stream from different locations.

The Blackmagic Design Intensity Shuttle accepts composite video directly, so no converter is needed. It costs around $200 and is overkill for 3DS streaming alone, but it is the choice if you want to capture multiple older consoles without adapters.

Setting up the hardware chain

The physical order is: 3DS → converter (if needed) → capture card → PC. Start by connecting the 3DS to the converter using the composite or component cables that came with the handheld. If you are using composite (the three-cable bundle), plug the yellow cable into the video input on the converter, and the red and white cables into the audio inputs.

Next, connect the converter's HDMI output to the capture card's HDMI input using an HDMI cable. Then plug the capture card into a USB 3.0 port on your PC — USB 2.0 will not provide enough bandwidth and will cause lag or dropped frames. If your PC has only USB 2.0 ports, you will need a USB 3.0 expansion card, which costs $20 to $40.

Power on the 3DS and the capture card. The card should light up or show a status LED. Open your PC's Device Manager (Windows) or System Report (Mac) to confirm the capture card is recognized. If it does not appear, try a different USB port or restart the PC.

Installing and configuring OBS Studio

OBS Studio is free software that captures video from your capture card and sends it to streaming platforms or saves it as a file. read it from obsproject.com for Windows, Mac, or Linux. Install it and open the process.

In OBS, click the plus sign under "Sources" and select "Video Capture Device." A menu will appear asking which device to use. Choose your capture card from the dropdown list. The 3DS video should appear in the preview window within a few seconds. If it does not, go to Settings → Output and confirm the video bitrate is set to at least 5000 kbps, and the resolution is set to match your capture card's output (usually 1920×1080, even though the 3DS sends only 240p).

Adjust the size and position of the video in the canvas by clicking and dragging the edges of the preview. You can add text overlays, a webcam feed, or background images by adding more sources. Once the layout looks right, you are ready to stream or record.

Streaming to Twitch or YouTube

To broadcast live, you need an account on Twitch, YouTube, or another platform. In OBS, go to Settings → Stream and select your platform from the Service dropdown. For Twitch, log in with your Twitch account and OBS will fill in your stream key automatically. For YouTube, you will need to copy your stream key from YouTube Studio and paste it into OBS.

Set your bitrate to 2500 to 4000 kbps if your internet upload speed is 5 Mbps or higher. The 3DS resolution is low, so you do not need the high bitrates required for modern console streaming. Click "Start Streaming" and OBS will begin sending video to your platform. Your stream will be live within 10 to 30 seconds.

Monitor your connection in OBS's Stats window (View → Stats) to watch for dropped frames or network issues. If you see red bars, lower your bitrate by 500 kbps and try again.

Recording 3DS gameplay to your PC

If you want to save video files instead of streaming live, go to Settings → Output and choose a folder where OBS will save recordings. Set the video bitrate to 8000 to 10000 kbps for higher quality files. Click "Start Recording" and OBS will create an MP4 file in your chosen folder. Stop recording when you are done playing.

The file size will be roughly 1 GB per 10 minutes of recording at 8000 kbps. Make sure your PC has enough free disk space before you start a long session. You can edit the video later in free software like DaVinci Resolve or Shotcut, or upload it directly to YouTube.

Troubleshooting common problems

If the 3DS video does not appear in OBS, first check that the capture card is powered on and connected to a USB 3.0 port. Restart OBS and the capture card. If the video still does not show, unplug the converter from the capture card, wait 10 seconds, and plug it back in. Sometimes the connection needs to be reset.

If the video is choppy or lags, your USB connection may be unstable. Try a different USB port, or if you are using a USB hub, plug the capture card directly into the PC instead. Also check that no other programs are using the capture card — close any other streaming or recording software.

If the audio is missing or out of sync, go to OBS Settings → Audio and confirm the audio input device is set to your capture card. Some converters require you to select the audio input separately from the video input. If audio is still missing, the converter may not be passing audio through — check the converter's manual or try a different model.

If your stream is dropping frames, lower your bitrate by 500 kbps and check your internet upload speed using speedtest.net. You need at least 5 Mbps upload speed for stable streaming at 3000 kbps bitrate.

Frequently Asked Questions

Can I stream the 3DS without a capture card?

No. The 3DS has no built-in streaming or screen mirroring feature, and there is no software that can capture its screen wirelessly. A capture card is the only method.

What is the best capture card for 3DS streaming?

The Elgato HD60 S+ is the most widely used because it is reliable and works with many consoles. The AVerMedia Live Gamer Portable 2 Plus is a cheaper alternative if you want to save money. Both require a composite-to-HDMI converter.

Do I need a powerful PC to stream 3DS?

No. The 3DS outputs only 240p video, so even a PC from 2015 with a basic processor can handle it. You need at least 4 GB of RAM and a USB 3.0 port, but the CPU load is very light.

Can I stream the 3DS and play on my monitor at the same time?

Yes. The capture card sends video to your PC, and OBS displays it on your monitor. You can play the 3DS while watching the stream on your PC screen, or use a second monitor if you prefer.

How much does a complete 3DS streaming setup cost?

A basic setup costs $100 to $150: a capture card ($100 to $150), a composite-to-HDMI converter ($15 to $25), and HDMI and USB cables (which you may already have). OBS Studio is free. If you already own cables, you can start for under $100.
