pyisotools

python library for working with Gamecube ISOs (GCM)

Features

• Extract and Build ISOs
• Extract individual files/folders from an ISO
• Specifically exclude subfolders/files using glob patterns
• Custom file alignment
• Custom file location
• Custom ISO metadata

Limitations

• Only supports Gamecube ISOs

TODO

• Support Wii ISOs
• ISO Partitions
• Native archive support (U8 and RARC)
• Native yaz0 and yay0 compression
• Cross platform file drag-drop to/from pyisotools
• File System real time search filter
• File System update real time

Usage

GUI

To run the GUI from the cli, simply pass: python -m pyisotools

Extraction

To extract an ISO from the cli, pass: python -m pyisotools <iso> E [--dest path]

Rebuilding

To build a root folder into an iso, pass: python -m pyisotools <root> B [--newinfo] [--dest path]

Configuration (rebuilding from cli)

When an ISO is extracted, a file named .config.json is automatically generated and stored in the sys folder in the root directory. This file contains metadata about the ISO, such as the name of the game, its version, maker code, and so on. Editing this file results in the new data being used if rebuilding with option --newinfo enabled. The fields that need clairification are listed below:

• Alignment: This field of key,value pairs defines the alignment of every file that matches the specified glob pattern set as the key, to be that of the value
• Location: This field of key,value pairs defines the position in the ISO of every file that matches the specified filepath set as the key, to be that of the value
• Exclude: This list of glob patterns determines if a file/folder is excluded or not. If a file/folder path matches any of the glob patterns in the list, it will not be built into the ISO

Configuration (GUI)

When a root is loaded, all metadata fields are accessible directly from the main window, and each node can be right clicked on to set the alignment, location, and exclude members
