VUEngine Studio is a custom integrated development environment (IDE), tailor-made for Nintendo Virtual Boy game development with VUEngine, a versatile, object oriented Virtual Boy game engine. It is built with Eclipse Theia, a framework for building cloud and desktop IDEs using modern, state-of-the-art web technologies. At its core, Theia reuses central building blocks of Visual Studio Code and as such, VUEngine Studio looks and feels very much like VSCode and is able to consume VSCode extensions.
