Emulicious – Game Boy / Game Gear / Master System emulator

Welcome to the official home of Emulicious!

Emulicious is a free to use multi-system emulator for Windows, Linux, Mac OS(X) and any other operating system supporting Java SE.
You don’t need to install Java on your system in order to run Emulicious. It only requires the Java binaries to run. For Windows users there’s a download including current Java binaries (see Emulicious Downloads Section).

Emulicious consists of the following emulators:

  • A Nintendo Game Boy Emulator
  • A Nintendo Game Boy Color Emulator
  • A Sega Master System Emulator
  • A Sega Game Gear Emulator

Even though Emulicious aims for precision and accurate emulation it still provides some additional features and tools:

  • Automatic Updates
  • Adjustable Turbo
  • Adjustable Throttle
  • IPS Patching
  • Savestates (Master System/Game Gear only)


  • Debugger (including an interactive disassembler with automated code/data separation)
  • Profiler
  • Tracer
  • Coverage Analyzer
  • Memory Editor
  • Palette Viewer
  • Tile Viewer
  • Tilemap Viewer
  • Sprite Viewer
  • Memory Tracer (Master System/Game Gear only)

The debugger provides many features that can be useful for ROM hacking and Homebrew development. It provides customizable syntax highlighting, trace logging, breakpoints and watchpoints. A Reference Hierarchy helps in understanding a program flow, the profiler helps in identifying hotspots. A powerful expression syntax allows the definition of useful conditions for breakpoints/watchpoints. Breakpoints halting on accesses of uninitialized memory and inconsistent states after interrupts can help to avoid unnecessary programming mistakes.
