What it is
BGB is a free Game Boy emulator and debugger for playing games and examining emulation. It emulates Game Boy, Game Boy Color, and Super Game Boy, with gamepad support, rewind, save states, low latency, and high-quality sound and graphics. ROMs can be loaded from ZIP and GZIP files. The debugger can analyze emulation, help create or modify ROMs, and create, search, load, and save cheat codes; supported formats include GameGenie and GameShark. BGB can also emulate the Game Boy Camera using an image file, test pattern, or webcam. TCP/IP linking connects BGB instances, while Super Game Boy multiplayer supports up to four gamepads. BGB is listed for Windows, and its maker says it also runs under Wine on Linux and macOS; 32-bit and 64-bit versions are provided. The listed current release is version 1.6.6, dated 2025-07-20. Game linking may not work with every game and requires a modern PC with very low lag. AVI recordings omit sound, which is recorded separately to WAV. The manual states that the program has no warranty and is used at the user's own risk.
