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
