I am not entirely sure how I stumbled onto this open source project. It all seems like a blur. The project name is GB Studio and it is a more user-friendly IDE (Integrated Development Environment) that allows game creators to create Gameboy and Gameboy Color games that can be exported into a ROM (to load into an emulator), flashed onto a game cartridge (with the write tools), or to HTML5 (to work on mobile devices).
