What is gb-studio?
GB Studio is a native desktop game development app for creating retro games for the Game Boy family of systems without requiring traditional programming. It helps hobbyists, students, game jam creators, and indie developers build top-down games, platformers, shooters, and other 2D projects with a visual workflow. The app includes drag-and-drop scene editing, event-based scripting, built-in debugging tools, and music creation features designed for Game Boy-style audio. Users can produce real ROM files for emulators and compatible hardware, and can also export projects for the web to share online. GB Studio is available for macOS, Windows, and Linux, and is published by Chris Maltby.

Safety overview
Status: Safe
GB Studio is legitimate creative software used to make and export game projects. It normally needs access to files and folders you choose so you can open projects, save work, import assets, and export builds. Removing the app will not damage macOS, but it can leave your game projects untouched in their own folders, so keep those projects backed up if you still need them.
Recommendation: Keep GB Studio if you create or edit GB Studio projects, export ROMs, or use its music and level-building tools. If you no longer use it, you can remove the app, but keep any project folders and exported games you want to preserve first.
