I started developing this before the first release on 3dsconv.py and we have 2 different targets. Mine wants to be a (almost, since it doesn't do region patching nor fw spoofing) replacement of 3DS Simple CIA Converter (aka noob-friendly), ihaveamac tool is for power users. GitHub is where people build software. More than 50 million people use GitHub to discover, fork, and contribute to over 100 million projects.

This guide will show you how to convert your.3ds ROMs to.cia files using GodMode9.
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.

.cia
for 3DS consoles, .3ds
for emulators or .nds
for Nintendo DS gamesThe following is a list of known file formats used by the 3DS.
.CXI - CTR Executable image - Are either packaged into a CCI/CSU for running off a cartridge, or packaged into a CIA for installing to the SDMC or NAND.
.CFA - CTR File Archive - Externalized Rom-FS. This is non-executable specialisation of the NCCH container format. Generally used in conjunction with an executable specialisation of the NCCH container format (CXI).
.APP - The per-console encrypted form of a NCCH file, used with installed titles, like eShop and CDN downloads.
.CAA - A CXI which uses a raw ELF for the ExeFS .code section. Also has no plain region.
.CCI - CTR Cart image - Burned into a ROM (or loaded by official debugging hardware). These are also the actual format of ROM dumps, and the response of read requests between a 3DS and a cartridge. This is simply a NCCH container, with a maximum of 8 NCCHs.
.CSU - CTR System Update - Format varies slightly with revisions.
.BSF - Descriptive data used when outputting ICN/BNR files. The .XBSF format used by CiTRUS is based on the concept of .BSF.
.RSF - Descriptive data used when outputting a CCI/CXI file. Specifies options such as: title, save type, and so on.
.DESC - Descriptive data used when outputting a CCI/CXI file. Like the .RSF format, but more complex (more complex in the options which it can specify). The signed NCCH RSA-2048 key pair is taken from this file.
.AXF - Pre-assembled ARM code. Before being linked into the ExeFS '.code' format. These are ARM specific ELF files. The Plain Region found in the CXI is also obtained from this file.
.BNR - Simply contains a .CBMD and a .BCWAV. The .CBMD has added padding, to make sure the .BCWAV is aligned to 0x10 bytes. It contains nothing else.(The .CBMD file's header is edited to reflect its new size)
.ICN - Contains icons, names and flags for an application
.ARC - Archive. A container of files, all compressed with LZ-10.
.BCMA - CTR Manual (an ARC file).
.SARC - Simple(?) Archive. A container of uncompressed files.
.BCFNT - CTR Font File (version 3).
.BFFNT - CTR Font File (version 4).
.CIA - CTR Importable Archive - This format allows the installation of titles to the 3DS. CIA files can contain NCCH files for installation to either the SDMC or CTR NAND. CIA files can also contain .SRL files (format for DS(i) executable images) for installation to the TWL NAND of the 3DS. Anything distributed over Download Play (including card software) is created with this format as well.
.TMD - Title Meta Data - The format is used with installed/installable titles. Notably they are found in .CIA files (plain text), on the SD card (encrypted), NAND (encrypted) and on Nintendo's CDN (plain text).
.CMD - Content Meta Data - The format is used to index installed .app files for installed titles. It is encrypted with a console unique keyslot.
.CTX, Content Transfer: When beginning eShop app downloads, this file is created. Later this file is written with actual data. When the download is completed, the file is deleted from SD card. (This might then be moved to NAND.) This is encrypted with a per-console key. It contains a signed cert followed by unknown data. It is only 1.50kbyte. Here is an example.[1]
.(B)CWAV - CTR waveform file format
.(B)CSTM - CTR stream file format
.(B)CSAR- CTR adaptation of BRSAR.
.CBMD - CTR Basic Model Data - Archive file before being made into a CTR banner for games or other applications.
.CTPK - CTR Texture PacKage
.CMDL - CTR MoDeL data
.CTEX - CTR TEXture data
.CCAD - CTR Celluloid Animation Data
.CSKA / .CSKLA - CTR SKeLetal Animation data
.CMATA - CTR MATerial Animation data
.CMDLA - CTR MoDeL Animation data
.CLGT - CTR LiGhT data
.CPTL - CTR ParTicLe data
.CLTS - CTR LookupableSetdata
.CENV - CTR ENVironment data
.CCAM - CTR CAMera data
.CMAT - CTR MATerial
.NSA - Archive used by several of the communication protocols in the 3DS.
.CRO - This is a CTR 'DLL'.
.CRS - This is a special CRO format file which contains symbols for .code (the 'static module').
.CRR - This contains data for verifying CRO files.
.MPO - Multi-Picture Object Format - Document describing the file format used in mpo files: http://www.cipa.jp/english/hyoujunka/kikaku/pdf/DC-007_E.pdf
.CGRP - CTR GRouP - Used to package several formats like (CWAR, CWAV, CWSD, CBNK, CSEQ, etc...) sort of like the Wii's MRG format. (They aren't the same structures but both package together several formats.)
The 3DS filesystem requires absolute paths. It can handle either short (8.3) and long (255 char maximum) file names.
