닌텐도 3DS는 게임 데이터, 음악, 3DS로 촬영된 사진 및 동영상을 저장하기 위해 SD 카드를 사용한다.

- sdmc/Nintendo 3DS/<ID0>/<ID1> 안에 저장된 모든 파일은 콘솔 고유의 키슬롯으로 암호화되어 있으며, nand/data/<ID0> 안에 저장된 파일은 MAC을 위해 이 키슬롯만을 사용한다. 이 디렉토리들 안의 모든 CTR 파일은 nand/private/movable.sed로 초기화된 키슬롯을 사용한다.
- ID0 is the first 0x10-bytes from a SHA256 hash.
- ID1 is the scrambled SD card CID from the SD card which this directory was originally created on. To generate this directory name from the original CID, first the CID is rotated 8-bits to the left. Then, each u16 is moved as described in the below table:
| Input rotated CID u16 index | Output CID u16 index |
|---|---|
| 6 | 0 |
| 7 | 1 |
| 4 | 2 |
| 5 | 3 |
| 2 | 4 |
| 3 | 5 |
| 0 | 6 |
| 1 | 7 |
DCIM - 닌텐도 3DS 카메라 애플리케이션으로 촬영된 사진 및 동영상이 이 디렉토리에 저장되어 있다. 인터넷 브라우저의 다운로드된 이미지도 이곳에 저장된다.
Note: Playing/Recording (3D) Videos was introduced with update 3.0.0-5. The 3D videos are in .avi format and the video frames use MJPG.
backups - This directory contains SD Title Savedata backups. For more info, see SD Savedata Backups.
dbs - This contains database files relating to the titles installed on the SD Card. These files are encrypted. For more info, see Title Database
title - Title data for titles installed to the SD Card are found here. All data in this directory is encrypted with a console-unique keyslot. For a list of SD Card titles see the Title list. For more info on the title data structure see Title Data Structure.
Nintendo DSiWare - DSiWare 타이틀은 이곳에 내보내진다.
Private
"Private" data is stored here as cleartext:
/Nintendo 3DS/Private/<Title ID Low>/
00020400 - 닌텐도 3DS 카메라 00020500 - 닌텐도 3DS 사운드
Under the camera private dir is phtcache.bin. When you want to install and see pictures with 3DS, rename to 8 numbers.mpo and save it on /DCIM. Under the sound private dir is: voice/XX/*.m4a. Where XX is 01-10, with sound saved as .m4a.
