oxGBC vs Pizza Boy C

oxGBC is a free Rust emulator for Game Boy and Game Boy Color. One portable emulation core supports Windows, macOS, Linux, Android, and browsers through WebAssembly. The project aims for high accuracy using sub-instruction CPU timing and dot-level PPU emulation, and is validated in CI against community test suites including Blargg, Mooneye, SameSuite, DMG-acid2, CGB-acid2, CGB-acid-hell, and Magen.

Gameplay options include multiple save-state slots, optional automatic save and restore, configurable rewind, and adjustable speed with Slow and Turbo modes. Keyboard and gamepad controls are rebindable, including button combinations. Video options include visual filters, LCD frame blending, built-in or user-defined palettes, and custom GLSL shaders through an optional OpenGL backend. The desktop interface has a file browser and scans ROM directories. Listed cartridge support includes MBC0, MBC1, MBC1M, MBC2, MBC3, and MBC5, including battery-backed MBC3 real-time clock and SRAM. The project is licensed under GNU GPL version 3.0. On macOS, Gatekeeper blocks the first launch until the app is opened manually through security settings or its quarantine is cleared.

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.
