Retro Boy is a cycle-accurate Game Boy emulator written in Rust that compiles to WebAssembly for browser-based play. It features accurate CPU, audio, and scanline-based graphics emulation, with a React web frontend and an SDL test frontend.
Use cases
- play game boy roms in the browser
- emulate game boy games on the web
- run a game boy emulator built with rust
- test game boy roms with an sdl app
- use game shark and game genie cheats while emulating
- save game boy cartridge ram and save states
When to choose
- you want to play Game Boy ROMs directly in a web browser
- you want a Rust-based emulator core that compiles to WebAssembly
- you need MBC1/MBC3/MBC5 cartridge support with RTC and persistent RAM
- you want a mobile-friendly emulator UI with customizable controls
When to avoid
- you need Game Boy Color, Game Boy Advance, or other console emulation
- you need a native desktop emulator with a polished GUI rather than a test app
- you require full save state support or netplay features
