Summary
oxGBC is a free emulator for Game Boy and Game Boy Color games, written in Rust. It runs on Windows, macOS, Linux, Android, and in browsers through WebAssembly, using one portable emulation core. The project aims for accurate emulation through sub-instruction CPU timing and dot-level picture processing, and validates the emulator against community test suites. Players can use multiple save-state slots, optional automatic saving and restoring, configurable rewind, and adjustable speed with Slow and Turbo modes. Keyboard and gamepad controls can be rebound, including button combinations. Video options include filters, LCD frame blending, built-in or custom palettes, and GLSL shaders through an optional OpenGL backend. The desktop interface has a file browser and can scan a ROM directory to launch games. Listed cartridge support includes MBC0, MBC1, MBC1M, MBC2, MBC3, and MBC5, including battery-backed MBC3 clock and SRAM. On macOS, Gatekeeper blocks the first launch until the app is opened manually or its quarantine is cleared.
