- Converting a.3DS to.CIA. For organizational purposes, copy each.3ds file you wish to convert to the /cias/ folder on your SD card Note that if you wish to convert a.3ds file that is already on a flashcart, you should follow Dumping a Game Cartridge; Launch GodMode9 by holding (Start) during boot.
- Just another 3DS to CIA converter for Linux and Windows. Usage Easy (precompiled version) Just unzip the released version, put your roms in the roms directory, put the xorpads in the xorpads directory and launch 3ds-to-cia.
- Transfer the.3ds files to my PC. Use 3DS Simple CIA Converter to convert the.3ds files to.cia files (https.
- The.3ds file does not appear to be broken, since it can run on Citra. However, I downloaded a different.3ds rom (not a rom hack) and it is building the.cia just fine. My best guess is that I can't build the.cia because it is a hacked rom or because the rom is decrypted. I tried encrypting the rom with GodMode9 but nothing works with it.
makerom is a tool which can be used to create NCCH, CCI, and CIA files.

Format Overviews[edit]
3DS games can also be found in.3ds format, however this is not compatible with 3DS consoles and is generally intended for 3DS emulators such as Citra.3ds files must be converted to.cia before they can be installed on your 3DS. Follow this guide on Converting 3DS ROMs to.cia with GodMode9.
NCCH[edit]
The native format storing code binaries and data archives for the 3DS is NCCH. NCCH files are comprised of:
- code/exheader/plainregion (used for code execution) (plainregion just lists included SDK library add-ons)
- icon (app title text, icon, homemenu settings, see here
- banner (cbmd + cwav, i.e. the upper screen banner/sound shown on the homemenu)
- logo (the splash screen displayed after an application is launched from the homemenu)
- romfs (read-only filesystem used to store resources)
Typical uses for NCCH files include:
- Executable image (code+exheader+icon+banner+logo+romfs)
- e-Manual archive (accessed from homemenu) (romfs)
- DLP child CIA archive (accessed from application) (romfs)
- Update Data archive (romfs)
- Standalone data archive (romfs)
- DLC index archive (icon+romfs)
- DLC archive (romfs)
CCI[edit]
The native format for gamecard images is CCI and is a NCCH container format. CCI files are limited to containing 8 NCCH files, and can contain NCCH files for applications titles only.
NCCH configuration for CCI[edit]
| NCCH | Required | Index |
|---|---|---|
| Executable image | YES | 0 |
| e-Manual archive | NO | 1 |
| DLP child CIA archive | NO | 2 |
| Update Data archive | NO | 7 |
CIA[edit]
The native format for packaging NCCH files for install is CIA, which is also a NCCH container format. CIA files are limited to containing 65535 NCCH files and can be used to contain NCCH files for any title type. CIA files also contain signed data used by the 3DS for general title management and DRM. Installing custom CIA files on a 3DS which also uses eShop/SysUpdates is unwise as conflicts will likely occur.
NCCH configurations for CIA[edit]
Applications (Application/DlpChild/Demo/Patch/SystemApplication):
| NCCH | Required | Index |
|---|---|---|
| Executable image | YES | 0 |
| e-Manual archive | NO | 1 |

Using Makerom[edit]
Command line[edit]
General Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -f <format> | 'ncch'/'cxi'/'cfa'/'cci'/'cia' | Specify the output file format. 'ncch'/'cxi'/'cfa' has no affect, probably parsed without error for legacy support. |
| -o <path> | Valid file path. | Specify name/path for output file. Makerom will decided a name if this is not specified. |
| -v | not required | Enables verbose output. |

Crypto Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -target <target> | 't'/'d'/'p' | Specify key-chain. This affects encryption, signing and '-desc' template availability. t=test, suitable for homebrew. d=devkit(incomplete), suitable for devkits. p=retail(unusable), suitable for signing retail software? |

Rebuilding CXI:
Creating RSF files[edit]
Inspired by Nintendo's format for their makerom, a yaml configuration file is required for creating NCCH files. CIA/CCI can be created without using a RSF file, but default settings will be used.
For CXI, RSF files can be used to specify permissions, and access control settings. Makerom can use default settings by use of the '-desc' option, which removes the requirement for specifying them in the RSF file.

Creating ELF files[edit]
The latest devkitARM used in conjunction with ctrulib can create ELF files compatible with makerom.
ELF files that are created using the official SDK are also supported by makerom.
Compiling Source[edit]
For Windows a MinGW-W64/MSYS build setup is required.
For Linux, gcc/g++/make must be installed.
All additional libraries used by makerom (polarssl/libyaml) are included in the source, and are linked statically.
