GoBoy review
A focused desktop emulator for GB/GBC games with useful debugging controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GoBoy is an open-source Nintendo Game Boy and Game Boy Color emulator written in Go. It is aimed at desktop users who want a focused way to run Game Boy games on macOS, Windows, or Linux. The project says it runs most Game Boy games and some Game Boy Color games, with color rendering and sound support. Its battery-backed save-file mechanism is designed for ROMs that support cartridge batteries, keeping the core experience close to cartridge-based saving.
The standout feature is its debugging output. GoBoy includes tools for inspecting opcodes, registers, palettes, sprites, and sound channels, while individual sound-channel toggles provide more control over audio behavior. Those functions make it more relevant to developers, emulator enthusiasts, and users interested in examining how games operate than to players seeking a large set of convenience features. Fullscreen and mute options cover basic desktop playback needs without changing the product's narrow focus.
GoBoy is distributed as source code and releases for three desktop platforms, giving it a broad operating-system target while retaining a work-in-progress status. Save states and MBC3 clock support are listed as TODO items, so it is a weaker fit for users who expect modern emulator conveniences or accurate real-time clock behavior. Choose GoBoy if GB/GBC coverage, open-source availability, and debugging depth matter more than feature breadth. Choose an alternative if save states, controller support, link functionality, or a more complete convenience layer are central requirements.
