3ds Simple Cia Converter Exheader Decryption Failed Version

Py2exe support for building a single.exe for Windows; Other small fixes; 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. It may not work on 32-bit without manually building the executable. Makecia is still required (on Windows, this can be in the same folder as 3dsconv.exe). 3ds to CIA converter this tool. It’s extremely simple as well as does not use Python or.NET Structure or any other programs and also scripts, just my very own code in a solitary exe file.

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.

NCCH configurations for CIA[edit]

Applications (Application/DlpChild/Demo/Patch/SystemApplication):

NCCH	Required	Index
Executable image	YES	0
e-Manual archive	NO	1
DLP child CIA archive	NO	2

System Applet/Module:

NCCH	Required	Index
Executable image	YES	0

System Data Archives:

NCCH	Required	Index
Data archive	YES	0

DLC:

The number of DLC data archives in DLC varies for each DLC.

NCCH	Required	Index
DLC index archive	YES	0
DLC data archive	YES	Varies

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
