ChillyGB vs GB Enhanced+

ChillyGB is a free Game Boy (DMG) and Game Boy Color (CGB) emulator written in C. It is listed for Windows, Linux, and Nintendo Switch, and the project links to a WebAssembly browser version. Supported cartridges include no MBC, MBC1, MBC2, MBC3 with a real-time clock, MBC5, MBC7, and Pocket Camera. Features include Game Boy Color and BootROM support, BESS-compliant save states, a palette editor, integer scaling, a pixel grid, color correction, and GameGenie and GameShark cheats.

Players can use basic gamepads and edit inputs; Pocket Camera support can use a webcam. The debugger includes instruction, memory, stack, and register views, plus editors and status information for listed PPU registers. The project excludes SGB functions, MBC6, HUc1, HUc3, and infrared communication. Link cable emulation and netplay are not supported. The browser port's audio is noted as buggy. ChillyGB is licensed under GNU GPL v3.0; release 0.3.2 is listed as latest, and save states from before version 0.3.0 do not work with it.

GB Enhanced+ is a free, open-source emulator for DMG, Game Boy Color, Game Boy Advance and Pokémon Mini systems, available on Windows, Linux and macOS. Nintendo DS emulation is described as experimental. The project focuses on emulating peripherals and less common hardware, with support listed for the Wave Scanner, Wantame Card Scanner, Vaus Controller and WorkBoy. It also supports link-cable emulation, real-time clock features, save states and controller input. Configuration options include joystick haptics, accelerometer input for motion controls and netplay settings for linking emulator instances. The emulator can automatically apply an IPS or UPS patch file when it shares a name with a ROM. PDF and ODT manuals cover operation, netplay, rumble support and motion controls. Building it requires SDL 2.0, OpenGL 3.3 or greater, a C++ compiler and CMake; Windows also requires GLEW. Qt for the GUI and SDL2_net for netplay are optional. It is licensed under GPLv2. Save states from version 1.9 and earlier are incompatible with version 1.10.
