ChillyGB vs Pizza Boy C

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.

Pizza Boy C is an Android emulator for Game Boy and Game Boy Color software. It provides save and restore states, fast forward, and slow motion, with hardware joypad support and serial link emulation through WiFi or Bluetooth. Players can adjust skins, graphics enhancements, cheats, palettes, borders, and control layouts. Screenshots can be saved as JPG images or animated GIFs. The maker says the emulator is written in C, targets 60 FPS even on old hardware, and uses little battery power. Pizza Boy C Basic is free, ad-free, and includes save states, fast forward, and slow motion. Pizza Boy C Pro costs 5.99 USD once. Games are not included, so users must supply ROMs. The maker says the apps have no account, analytics, advertising, or crash-reporting SDKs and work almost entirely on-device. Google Play lists no data collected or shared for Basic or Pro.
