What is a .BYML file?
A .BYML file is a type of binary file that stores data in the YAML format, which stands for YAML Ain't Markup Language. YAML is commonly used for writing configuration files that are easy for humans to read and write. In the case of .BYML files, the YAML data is converted into a binary format, which makes it more efficient for computers to process but less readable by humans.
These .BYML files are specifically used in the development and functioning of certain Nintendo video games to manage various configuration settings. For example, they can dictate different game settings or define which levels or options are available in the game. Popular Nintendo games that use .BYML files include The Legend of Zelda: Breath of the Wild, Splatoon 2, Super Mario Odyssey, and Animal Crossing: New Horizons.
To open a .BYML file, you would typically use a specialized tool designed for handling such files. One common tool is known as "byml-v2," which can interpret the binary format and allow developers or advanced users to view or modify the contents.
It's important to note that .BYML files might also appear with other file extensions like .baischedule, .baniminfo, .bgdata, .bgsvdata, .bquestpack, .mubin, or .byaml. These are variations of the same binary YAML format, tailored for different types of data or uses within the game development process.
In summary, .BYML files are binary versions of YAML files used primarily by Nintendo for game configuration. They are opened using specific tools that can handle the binary format, such as byml-v2.
