Open the cia converter program, create ncchinfo.bin. This is something you'll need to make xorpads, which is used to convert.3ds to a.cia Copy that ncchinfo.bin to your SD card, slap it back into your 3DS and run Rxtools. Go to decryption options and then generate xorpads. 3DS Hacks - Convert 3DS ROMs to.cia 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. .3ds files are just files for flashcarts. They aren't encrypted. Unless the specific one you have is encrypted for whatever reason, there's no way for us to know how to Decrypt it other than you asking the uploader. You can convert a standard.3ds file to.cia simply by clicking the file from in Godmode.

Installing[edit]
Applications are installed by copying the necessary files directly to the 3ds/ folder in the root of the SD card (preferred for new designs), or in a subdirectory of 3ds/, in which case said subfolder must be named identically to its executable. Most applications come with two files:
[appname].3dsx: The executable.[appname].smdh: The icon/metadata. (Not required in any case, and may be integrated into the.3dsx)[appname].xml: The list of supported targets (i.e. installed titles which the app supports replacing in memory at runtime, thus inheriting its permissions), and of any arguments to be passed to the .3dsx. (Optional)
A standalone .xml file can point to a differently-named .3dsx, launching it with potentially different arguments so that a single application can run in different modes.
The Homebrew Launcher will scan the SD card for all .3dsx files, but will only display an icon for those who have one according to the format described above. Recent enough versions can freely navigate the filesystem to select an application.

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]
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.

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. |
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? |
| -ckeyid <index> | Any value between 0-255 (inclusive). | Overrides the default common key used to encrypt CIA title keys. |
| -showkeys | none | Dumps loaded key-chain to stdout. |
NCCH Build Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -elf <file> | Valid file path | Specify ELF. See below for creating ELF. |
| -icon <file> | Valid file path | Specify icon. |
| -banner <file> | Valid file path | Specify banner. |
| -desc <apptype>:<fw> | <apptype>='app'/'ecapp'/'demo'/'dlpchild'. <fw>='kernel version minor'. | Use a template for exheader/accessdesc. These are hard-coded, so not all firmwares have a template. A value from 1-7 can be used in place of 'kernel version minor'. A template shouldn't be used if the title needs 'special' permissions, the RSF must be configured fully. |
| -exefslogo | none | Include logo in ExeFS. Required for usage on <5.0 systems. |
Arguments useful for rebuilding a NCCH file:
| Argument | Acceptable values | Notes |
|---|---|---|
| -code <file> | Valid file path | Specify decompressed/plaintext exefs code binary. |
| -exheader <file> | Valid file path | Specify plaintext exheader binary. |
| -logo <file> | Valid file path | Specify logo. |
| -plainrgn <file> | Valid file path | Specify NCCH plain-region. |
| -romfs <file> | Valid file path | Specify an unencrypted RomFS binary. |
CCI Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -content <path>:<index> | <path>=Valid file path. <index>=Any value between 0-7 (inclusive) | Include a built NCCH file in the CCI container. '-i' can be used instead of '-content'. |
| -devcci | none | Build a debug CCI? |
| -nomodtid | none | Don't modify the TitleIds of NCCH files included to match NCCH0 |
| -alignwr | none | Align the offset for the Card2 writable region to the end of the last NCCH in the CCI. |
CIA Arguments
| Argument | Acceptable values | Notes |
|---|---|---|
| -content <path>:<index>:<id> | <path>=Valid file path. <index>=Any value between 0x0-0xFFFF (inclusive). <id>=Any value between 0x0-0xFFFFFFFF (inclusive) | Include a built NCCH file in the CIA container. If <id> isn't specified, it will be generated randomly. '-i' can be used instead of '-content'. |
| -major <version> | Any value between 0-63 (inclusive) | Specify the version major for the title. This cannot be used with '-dver'. |
| -minor <version> | Any value between 0-63 (inclusive) | Specify the version minor for the title. This cannot be used with '-dver'. |
| -micro <version> | Any value between 0-15 (inclusive) | Specify the version micro for the title. |
| -dver <version> | Any value between 0-4095 (inclusive) | Specify the or '-minor'. |

Examples[edit]

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 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]
Download os x el capitan 10.11. 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.
