This page contains a few short tutorials on how to use the RCF Builder.

These instructions can be used in a Command Prompt window or in a batch file. You will need to replace the paths in these examples with where you put the tool and where you have your input/output files and folders.

Extracting an RCF

To extract an RCF file, use the following command line arguments:

"C:\path\to\LRCFB.exe" -inputrcf "C:\path\to\input\file.rcf" -outputdir "C:\path\to\extract\to"

Building an RCF

From scratch

To build an RCF file from scratch, use the following command line arguments:

"C:\path\to\LRCFB.exe" -inputdir "C:\path\to\input\from" -outputrcf "C:\path\to\build\to\file.rcf"

You must also use -bigendian when building files for Nintendo GameCube games.

From an existing RCF and a directory

To build an RCF file from an existing RCF and a directory, use the following command line arguments:

"C:\path\to\LRCFB.exe" -inputrcf "C:\path\to\input\from\file.rcf" -inputdir "C:\path\to\input\from\dir" -outputrcf "C:\path\to\build\to\file.rcf"

For files that exist in both the RCF and the directory, the latter will be prioritized.

You must also use -bigendian when building files for Nintendo GameCube games.

Updating an RCF

To update the contents of an RCF file with that of a directory, use the following command line arguments:

"C:\path\to\LRCFB.exe" -rcf "C:\path\to\input\from\file.rcf" -inputdir "C:\path\to\input\from"

You must also use -bigendian when building files for Nintendo GameCube games.
