Type of format
Description	3DS is one of the file formats used by the Autodesk 3ds Max 3D modeling, animation and rendering software. It was the native file format of the old Autodesk 3D Studio DOS, which was popular until its successor replaced it in April 1996. Having been around since 1990, it has grown to become a de facto industry standard for transferring models between 3D programs, or for storing models for 3D resource catalogs. While the 3DS format aims to provide an import/export format, retaining only essential geometry, texture and lighting data, the related MAX format also contains extra information specific to Autodesk 3ds Max, to allow a scene to be completely saved/loaded.
Technical details	3ds is a binary file format. Format is based in chunks, where each section of data is embedded in a block that contains a chunk identifier and the length of the data, as well as the data itself. This allows parsers to skip chunks they don't recognize, and allows for extensions to the format. The chunks form a hierarchical structure, similar to an xml DOM tree. The first two bytes of the chunk are its ID. From that value the parser can identify the chunk and decide whether it will parse it or skip it. The next four bytes contain a little-endian integer that is the length of the chunk, including its data, the length of its sub-blocks and the 6-byte header. The next bytes are the chunk's data, followed by the sub-chunks, in a structure that may extend to several levels deep.

How to Transfer 3DS Save Data to Citra

There are multiple ways to transfer 3DS save data to Citra in a usable form, but the important thing to note is that whatever tool used to get the save data off of the 3DS supports exporting expanded save data. Save data lives in Citra’s emulated SD card directories (user/sdmc/Nintendo 3DS/000...0/000...0/title/[game-TID-high]/[game-TID-low]/data/00000001/).

threeSD

threeSD is a tool written to help import data from your 3DS for Citra more conveniently.

Refer to threeSD Quickstart Guide for importing your installed titles, updates, DLCs, save data, extra data, system files, etc. Note that you’ll still need a hacked 3DS with GodMode9 to obtain your keys so that threeSD can decrypt the data on your SD card.

Checkpoint

As the supported way of transferring save data, Checkpoint is easy to install and use.

Required tools

• A 3DS with boot9strap installed
• Checkpoint.
• SD card reader (preferred), or a way to use wireless file transfer

Installing Checkpoint

1. Download Checkpoint from the link above.
2. For cia installation, transfer the cia file to the SD card and install it with a cia installer such as FBI. For Rosalina-based Homebrew Launcher, transfer the 3dsx file to /3ds/ on the SD card. Hax-based Homebrew Launchers are not supported by Checkpoint.

Transferring Save Data

1. Open Checkpoint. If this is the first time launching Checkpoint, it may take a considerably longer than usual depending on the amount of installed titles.
2. Highlight the game you want to dump by navigating to it with the D-pad.
3. Press A and select Backup on the bottom screen. You will be prompted Yes or No. Select Yes by pressing A.
4. You will have the option to name the save folder. Name it whatever you want or use the name given to it. Press OK on the bottom screen.
5. The top screen will flash a message Success! Progress correctly saved to disk. Exit out of Checkpoint.
6. Transfer all files located in /3ds/Checkpoint/saves/[Game Name]/[Folder created in Step 4] to the computer.
7. Place the files in Citra’s emulated SD card’s save directory. You can open the save directory by right-clicking on a game in Citra and clicking “Open Save Data Directory”. If the directory doesn’t exist, start the game once and the directory will be created.
