GoBoy vs Pizza Boy C

GoBoy is a free, open-source emulator for Nintendo Game Boy and Game Boy Color, written in Go. It runs most Game Boy games and some Game Boy Color games, with color and sound support. Builds are listed for Linux, macOS, and Windows; users can download a release or install from source using Go and the documented commands. Debugging options print opcodes and register values or toggle individual sound channels. The listed controls are arrow keys, Z, X, Enter, and Backspace, with shortcuts for palette changes and fullscreen. For battery-backed ROMs, GoBoy creates a save file beside the ROM and updates it every second while the game runs. It uses the Pixel library for graphics and controls, which requires OpenGL; Linux builds also require GTK, and Windows 10 builds require MinGW. The project describes itself as a work in progress and development exercise, and lists unresolved graphics, audio, and cartridge issues. Save states and boot ROM support remain TODOs.

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.
