ChillyGB
What it is
ChillyGB is a free emulator for Game Boy (DMG) and Game Boy Color (CGB) systems, written in C. The project lists Windows and Linux versions and links to a WebAssembly browser port; release notes also mention Nintendo Switch support. Supported cartridges include MBC1, MBC2, MBC3 with real-time clock, MBC5, MBC7, and Pocket Camera. Features include BootROM support, BESS-compatible save states, a palette editor, integer scaling, pixel grid, color correction, and GameGenie and GameShark cheats. Players can use basic gamepads and edit inputs. The Pocket Camera can use a webcam, and Switch features include camera support through its IR sensor and accelerometer support with MBC7 games. A debugger provides instruction, memory, stack, and register views, plus PPU register status and editors. The browser version’s audio is described as somewhat buggy. Link cable emulation and netplay are not supported, and the project excludes several cartridge and hardware features. ChillyGB is licensed under GNU GPL v3.0. Version 0.3.2 is the latest listed release; save states from before 0.3.0 do not work.

Who it suits
ChillyGB suits players seeking a Game Boy or Game Boy Color emulator with configurable controls, cheats, save states, and debugging tools. Its browser version may be an option for those willing to account for the noted audio issue.
