RARC file

To do: Document technical information about RARC files.

The RARC/ARC file format is an archive format commonly found in first party Nintendo GameCube games. Many files are stored in these archive files in a similar way to ZIP and 7Z files.

In Pikmin 2's file structure, ARC files are nowhere near as common as the SZS file, which is a version of the format that's compressed via Yaz0 compression.

Extracting these files is done by using Lunaboy's RARC Tools via dragging the archive file to ArcExtract.exe.

When repacking an extracted archive with Lunaboy RARC Tools, you may notice that the file size is much bigger compared to what you wanted to edit. This is because you would need to compress the ARC via GameCube File Tools, which offers Yaz0 Compression.
