RetroGBm review
A focused, free GBC emulator with saves, link support, cheats, and controller support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RetroGBm is a free, open-source Game Boy Color emulator for Windows and Android. It is aimed at players who want focused GBC emulation with cartridge compatibility, save management, link-cable support, and hardware-control options. The project is written in C++ and distributed under the GNU GPL-3.0 license, with source code and release builds provided through its public repository. Its scope is deliberately narrow: this is a Game Boy Color tool rather than a multi-system emulator.
Its strongest feature set is the combination of compatibility and session flexibility. RetroGBm supports MBC1, MBC3, and MBC5 cartridge mappers, along with battery-backed saves and multiple rotating save states. Real-time clock emulation supports games that depend on clock behavior, while cycle-accurate CPU and PPU timing and audio emulation address core parts of the Game Boy Color experience. Play-time tracking, external controller support, adjustable emulation speed, and GameShark cheat codes add practical options for different play styles.
Link-cable support gives RetroGBm a clear advantage for buyers looking beyond solo play, while the Windows and Android releases cover desktop and mobile use within its stated platform range. The trade-off is system coverage: users seeking Game Boy Advance or other console emulation should choose a broader emulator instead. RetroGBm fits buyers who specifically want free Game Boy Color emulation, open-source distribution, save states, real-time clock behavior, and link support. It is less suitable for anyone who needs a wider library of supported systems or a broader platform selection.
