Download files straight onto your Nintendo 3DS, from a link, a QR code or your phone.

Website  ·  Download  ·  Guide  ·  Roadmap

3dsDL downloads files onto the SD card while the console stays on, with no card reader and no computer. Scan a QR code, type a link or send one from your phone, and it saves the file, installs it if it's a CIA, and lets you manage what's on the card. It's built to replace FBI, which is no longer maintained, and it looks and feels like the console's own system software.

• Downloads over verified HTTPS, split across up to four connections when the server allows it (fewer if you set a lower limit in Settings), with resume after a dropped connection.
• Installs CIAs with their seeds, or streams them straight into the install service when the SD card is too full.
• Receives links from a phone on the same Wi-Fi, and from FBI's servefiles.py, sendurls.py and Boop.
• Manages the SD card from a phone or computer's browser: upload, download, edit, move and delete files, and install uploaded CIAs, with no FTP app. Also answers at http://3ds.local/.
• A queue for scanning many QR codes in a row and downloading them together.
• Files: a file manager with a picture viewer, a text editor, ZIP extraction, a hex view and SHA-256 checks.
• Titles: launch and delete installed software, manage tickets and seeds, and clear stuck installs.
• Save data and extra data backup, restore and browsing, compatible with Checkpoint's backups.
• Updates itself from GitHub releases, checking each download against its SHA-256 checksum.

See the guide for how each part works, the controls and the settings.

You need a 3DS with custom firmware (3ds.hacks.guide) and Wi-Fi.

_{In FBI, choose Remote Install → Scan QR Code and scan this.}

• CIA: scan the code above in FBI, or install 3dsDL.cia from the latest release.
• 3DSX: copy 3dsDL.3dsx to sdmc:/3ds/3dsDL/ and open it from the Homebrew Launcher.

You only install 3dsDL once. It checks GitHub for a new version when it opens and shows a notification when there is one. Settings → Updates downloads the right build, checks it against the release's SHA-256 checksum and installs it, without FBI or a computer. The one exception is the 0.7.0 CIA, which crashes at start-up: install the latest release with FBI once.

git clone https://github.com/ankushKun/3dsDL.git
cd 3dsDL
./scripts/build.sh        # Docker build; results in dist/
make -C tests check       # host tests

Build options, building without Docker and the project layout are in the guide.

• Multidownload by hax0kartik, which 3dsDL grew out of.
• FBI by Steveice10, whose install sequence, seed handling and remote install protocol 3dsDL follows.
• Checkpoint by Bernardo Giordano, whose backup format and restore steps 3dsDL matches.
• Colby Shores, for the socket buffer and TLS randomness findings.
• libcurl, Mbed TLS, the Mozilla CA bundle, quirc (license), QR Code generator, stb_image, libjpeg-turbo, and devkitPro with libctru and Citro2D.
