Super Mario Maker 2 Course Data

A BCD file may also be part of a game level created by Super Mario Maker 2, a Super Mario level creator available for the Nintendo Switch. It contains binary data specifying the level's layout and some associated metadata . BCD files are stored with accompanying DAT and BTL files, which contain other data associated with the level.
More Information
Super Mario Maker 2 is the sequel to the original Super Mario Maker. Just like in Super Mario Maker, Super Mario Maker 2 players can create and play their own Super Mario levels. Players can also publish their levels online so others can play them.
Unlike Super Mario Maker levels ( .CDT files), Super Mario Maker 2 levels are stored as a package of three files. The level's BCD file contains most of its data, such as the placement of terrain, objects, and enemies. Super Mario Maker 2 players and modders use BCD files, and their associated DAT and BTL files, to examine and modify Super Mario Maker 2 levels, and distribute levels offline.
Common BCD Filenames
course_data_###.bcd - The name assigned to Super Mario Maker 2 course data files.
How to open a BCD file
You can open a BCD file with TheGreatRambler's online Super Mario Maker 2 Level Viewer, to see the layout of the level the file contains. You can also use SMM2 Level Viewer (Windows) to view a Super Mario Maker 2 level. However, SMM2 Level Viewer requires users to submit a level's code to view that level, rather than open the level's BCD file.
