Gambatte (open-source project)

Gambatte is an open-source emulator for the Nintendo Game Boy and Game Boy Color platforms. It focuses on high accuracy and compatibility with original hardware behavior and has been used widely by hobbyists, preservationists, and speedrunning communities to run, test, and analyze classic Game Boy titles. The project is distributed as source code and builds, and third-party binaries (such as gambatte_speedrun.exe) are commonly produced by community members.

Originally developed and refined by multiple contributors over many years, Gambatte is now maintained on GitHub with active maintainers such as sinamas. The project is not a commercial company but a community-driven repository of emulator code; it is incorporated into various frontends and toolchains (including libretro/RetroArch cores and bespoke builds for tools used by speedrunners). Its focus remains accurate emulation, debugging capabilities, and portability across platforms.
