GB Studio
What GB Studio is
GB Studio is a drag-and-drop creator for making games for the Game Boy. Its visual scripting is designed for people with little or no programming knowledge. The project editor brings scenes, actors, triggers, and scripting events into one workspace, with tools for collision setup and color drawing. A debugger can show game state and variable values, pause at breakpoints, step through scripts, and display build warnings. The built-in music editor offers piano roll and tracker modes, accepts MIDI input, and has four channels with 45 configurable 8-bit instruments. It also supports hUGETracker patterns, while GBS Music can export tracks in MP3, WAV, or FLAC formats. Projects can be built as ROM files for emulators or real Game Boy hardware, or as web pages; exported games can be uploaded to itch.io. Plugins can add reusable assets, custom scripting events, and engine changes. Advanced users can access GBVM and modify the engine’s C and SM83 assembly code through plugins; engine editing is recommended for developers familiar with GBDK. GB Studio is free under the MIT license and is listed for Linux, macOS, Windows, and web. Its listed release, version 4.3.2, added web templates and bug fixes.
