- How To Use 3ds to CIA converter 1) Put your 3DS video games into ‘roms’ folder and press ‘Produce ncchinfo.bin data’ switch to develop ‘ncchinfo.bin’ from 3DS ROMs. 2) Make Use Of GodMode9 in addition to developed ‘ncchinfo.bin’ to produce ExHeader XORpads, put it in origin of SD card, launch GodMode9 as well as comply with.
- EzyZip is a free online utility for extracting cia files from a 7zip archive.No need to install additional software as it runs in the browser. It supports a bunch of other file extraction and conversion options too.
- Manually builds the CIA now; makerom is no longer needed This should mean lower-memory computers can properly convert larger games. The 3dsconv.exe in this release includes all the necessary libraries and a Python interpreter, so it should be usable on 64-bit Windows without Python installed.
Nintendo 3DS games can often be found in the .3ds format, which is intended for emulators like Citra. Nintendo 3DS consoles cannot load .3ds ROM files, however they can be converted to .cia format which can be installed on hacked 3DS consoles with FBI. This guide will show you how to convert your .3ds ROMs to .cia files using GodMode9.

Format Overviews[edit]
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]
Excel emulator mac. 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 |

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. |
RSF Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -rsf <path> | Valid file path | Specify the path to Rom Specification File(RSF). See below for creating RSF. |
| -D<NAME>=<VALUE> | This is used to substitute where '$(<NAME>)' exists in the RSF files with '<VALUE>'. (Uppercase isn't a requirement) |
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? |

Examples[edit]
3ds To Cia Converter Rar
General examples:
Create CXI
Create CFA
Create CCI
Create CIA
Makerom supports building a NCCH file and including it automatically (as index 0) into a NCCH container:
Create CCI and CXI at the same time and include a CFA
Create CIA and CXI at the same time and include a CFA
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.
Sample RSF to be used with '-desc': download (link broken)
Sample RSF to be used without '-desc': download
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.
