Documentation of the .cia file format and 3DS injection

• ILSpy

  42 20,157 9.2 C#

  .NET Decompiler with support for PDB generation, ReadyToRun, Metadata (&more) - cross-platform!

  

Those apps are written in .NET and are compiled to CIL, which is easily decompilable with a tool such as ILSpy or the Mono disassembler

• Project_CTR

  3 387 3.8 C

For open-source tools, Project CTR includes ctrtool to extract many 3DS formats including CIA, and makerom to build an NCCH, CIA, or CCI file. It's a bit old so I'm not positive it'll work exactly, but there's a guide on extracting a CIA using ctrtool and 3dstool, then rebuilding it using makerom and 3dstool.

• open_agb_firm

  60 795 6.7 C

  open_agb_firm is a bare metal app for running GBA homebrew/games using the 3DS builtin GBA hardware.

I'm not sure if there's an existing open-source tool for creating CIA files of GBA games. A lot of focus has moved to open_agb_firm, which allows running GBA ROMs directly using the native hardware support, and has many advantages over the official implementation.
