What is a GBSPROJ file?

A GBSPROJ file is a project file created by GB Studio, a program used to create custom Game Boy video games. It contains JSON-formatted information about a game project. For example, GBSPROJ files list a project's name, author, and included scenes. GB Studio uses the information that GBSPROJ files contain to open the described game project.

Using GB Studio, Game Boy enthusiasts can develop and publish their own Game Boy games. When a developer saves their game development project, GB Studio creates a project-specific directory. This directory contains all the project's assets, a GBSPROJ file, and a GBSPROJ.BAK file (a backup of the GBSPROJ file).

GBSPROJ files are renamed .JSON files that contain project metadata and describe a project's structure and included assets. To re-open a GB Studio project, developers select and open that project's GBSTUDIO file.

NOTE: If a GBSTUDIO file is not stored alongside its associated assets, the file and associated project will not open correctly.
