Summary

ChillyGB is a Game Boy (DMG) and Game Boy Color (CGB) emulator written in C, with builds or versions listed for Windows, Linux, Nintendo Switch and the browser. It supports cartridge types including MBC1, MBC2, MBC3 with a real-time clock, MBC5, MBC7 and Pocket Camera. Emulation options include BootROM support, BESS-compatible save states, a palette editor, integer scaling, a pixel grid, color correction and GameGenie or GameShark cheats. Players can use basic gamepads and edit inputs; Pocket Camera support can use a webcam, and the Switch version lists camera support through its IR sensor and accelerometer support for MBC7 games. A debugger provides instruction, memory, stack and register views, plus editors for several PPU registers. The browser version's audio is noted as buggy. Link cable emulation and netplay are not supported, and the project excludes several cartridge and hardware features. ChillyGB is free under GNU GPL v3.0. Release 0.3.2 is listed as the latest, and states created before 0.3.0 are incompatible.
