What is a BYML file?
A BYML file is a binary file that contains YAML data. It is used to control configuration settings in a Nintendo video game. BYML files are used in several popular games, including The Legend of Zelda: Breath of the Wild, Splatoon 2, Super Mario Odyssey, and Animal Crossing: New Horizons.
More Information
YAML (YAML Ain't Markup Language) is a human-readable data format used for data serialization. .YAML files are most often used as configuration files, which define an application's settings.
Some Nintendo video games use YAML files that have been converted to a binary format, which are saved as BYML files. These files control in-game settings and characteristics, such as what levels are available to select.
NOTE: BYML files may also be saved with the .baischedule, .baniminfo, .bgdata, .bgsvdata, .bquestpack, .mubin, or .byaml extension.
How to open a BYML file
BYML files are binary files that are typically not meant to be opened. However, you can convert a BYML file to a YAML file using byml-v2 (cross-platform), a fan-created BYML conversion tool. Then, you can examine and edit the YAML data your BYML file contains.
