oead 1.2.9.post4

Library for recent Nintendo EAD formats in first-party games

oead is a C++ library for common file formats that are used in modern first-party Nintendo EAD (now EPD) titles.

Python bindings for 3.6+ are also available.

Features

Currently, oead only handles very common formats that are extensively used in recent games such as Breath of the Wild and Super Mario Odyssey.

• AAMP (binary parameter archive): Only version 2 is supported.

• BYML (binary YAML): Versions 1, 2, 3, and 4 are supported.

• SARC (archive)

• Yaz0 (compression algorithm)

oead also supports a recent Grezzo format that is used in Link’s Awakening (Switch):

• gsheet (Grezzo datasheet)

Getting started

To install the Python module, simply run:

pip install oead

This will download and install a precompiled version of oead for the following platforms:

• Windows (x86-64 / 64-bit)

• Recent Linux distributions (x86-64, glibc and musl)

Precompiled builds for macOS are currently unavailable as the wheel build process seems to be broken. Please help us fix this release failure <https://github.com/zeldamods/oead/actions/runs/9588470856/job/26440567392> if you know how!

The following versions of Python are supported:

• CPython 3.6 to 3.12

• PyPy3.7 to 3.9

If you are using any other platform, you must build oead from source (refer to the next section).

Warning

Windows users must ensure that they have the latest Visual C++ 2019 Redistributable installed.

For more information, refer to the documentation.

Building from source

Building oead from source requires:

• CMake 3.12+

• A compiler that supports C++17

• Everything needed to build libyaml

First, clone the repository then enter the oead directory and run git submodule update --init --recursive.

Building the Python module

• To install the module, run pip install -e .. This requires the following Python modules to be installed: setuptools, wheel

• If you just want to build the Python module from source without installing it, run python setup.py bdist_wheel.

C++ usage

Linking to the oead target is sufficient to use the library.
