What is a JSB file?

JSB files mostly belong to Cocos Creator. JSB files are binary files that store game data and compiled JavaScript code. They are used primarily in games and related applications to secure and manage data.
Usage and Functionality include:

Game Save Data: These files are used as save files in games such as Just Survive and Football Manager. For instance, Football Manager uses a Binary JavaScript Session File format (Football Manager) to keep game state data encrypted.

Game Data Files: Titles like Pro Evolution Soccer store essential data here as a JavaScript Binary File. This use helps manage game settings and progression internally.

Compiled Code Bundles: In several cases, JSB files contain compiled JavaScript or bytecode. Tools from companies like Cocos Creator (Cocos Creator) create such files to bundle code in a secure, non-readable format.

Script Files: Some JSB files, such as those for JAWS for Windows, serve as script files to run specialized functions. More details can be found at Freedom Scientific.

These files are not meant to be opened with a simple text editor because their binary structure hides the original JavaScript code.
Opening & Viewing: To access their content, you must use dedicated developer tools or game-specific editors that can handle encrypted and compiled data.

JSB file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our analysis of the JSB files produces the following result:
