Coffee GB vs Pizza Boy C

Coffee GB is a desktop emulator for the original Game Boy and Game Boy Color, with support for Super Game Boy features. It runs on Windows, macOS, Linux, and Android, and accepts .gb, .gbc, and .rom files, including games inside ZIP and 7z archives. ROM files are not included. For saving and reviewing play, it offers ten slots, named save states with previews, autosave and resume, screenshots, input recordings, and rewind. Rollback netplay supports link-cable games and synchronized infrared communication. Keyboard and controller input are supported, with separate controls for up to four players in compatible Super Game Boy games. Cartridge support includes real-time clocks, rumble, tilt, Game Boy Camera, and Game Boy Printer. Cheats include Game Genie and GameShark, with a searchable libretro database. The project reports 5,858 automated verdicts passing across 17 test suite families. Coffee GB is free and distributed under the MIT License. Netplay uses a direct, unencrypted TCP connection; the project advises using trusted people and networks. On macOS, controllers require compatible system SDL2, though keyboard input and emulation work without 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.
