Since CCI and CIA are NCCH containers, makerom was built so CXIs could be built stand alone, or straight into a container format. It is also possible rebuild CXIs as easily building a CXI from an elf. As a result the are many combinations which can be used, and for simplicity specific functions will be explained by breaking them up into argument groups:

Inspired by Nintendo's format for their makerom, is a yaml configuration file, required for creating NCCH files. CIA/CCI can be created without using a RSF file, but default settings will be used.

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. However makerom can use default settings by use of the "-desc" option, which removes the requirement for specifing them in the RSF file.

=== Creating ELF files ===

ELF files created using the official SDK can be used with makerom. But ELF files created using [https://github.com/smealum/ctrulib ctrulib], can be used, provided they are linked with this linker script: [https://gist.github.com/yellows8/6da7984a80a825b10294 download]
