Mednafen – multi-system emulator

Mednafen is a portable, utilizing OpenGL and SDL, argument (command-line)-driven multi-system emulator with many advanced features.

It emulates:

  • Atari Lynx.
  • Neo Geo Pocket (Color).
  • WonderSwan.
  • GameBoy (Color).
  • GameBoy Advance.
  • Nintendo Entertainment System.
  • Super Nintendo Entertainment System/Super Famicom.
  • Virtual Boy.
  • PC Engine/TurboGrafx 16 (CD).
  • SuperGrafx.
  • PC-FX.
  • Sega Game Gear.
  • Sega Genesis/Megadrive.
  • Sega Master System.
  • Sega Saturn (experimental, x86_64 only).
  • Sony PlayStation.

Save states are supported, as is real-time game rewinding. Screen snapshots may be taken at the press of a button, and are saved in the popular PNG file format.

Due to the threaded model of emulation used in Mednafen, and limitations of SDL, a joystick is preferred over a keyboard to play games, as the joystick will have slightly less latency, although the latency differences may not be perceptible to most people.

Features include:

  • Double-buffered video, enabled by default.
  • Multi-threaded video blitting, allowing for a kind of software triple-buffering, and improving performance on SMP systems.
  • Joystick support.
  • Extremely versatile input configuration system; assign multiple physical buttons to a virtual button or action.
  • Full-screen modes.
  • Save states.
  • Real-time game rewinding, up to 10 seconds.
  • Remap hotkey functions and virtual system inputs to a keyboard, a joystick, or both simultaneously.
  • Screen snapshots, saved in PNG format.
  • Loading games from gzip and (pk)zip compressed archives.

  1. Huh. I thought Mednafen could run SNES and Mega Drive/Sega Genesis games too, among others. I had heard of it as a many-in-one emulator, so I thought of picking it up. Guess I was misled.

    1. The project makes it VERY clear what it supports:

      Atari Lynx
      Neo Geo Pocket (Color)
      WonderSwan
      GameBoy (Color)
      GameBoy Advance
      Nintendo Entertainment System
      Super Nintendo Entertainment System/Super Famicom
      Virtual Boy
      PC Engine/TurboGrafx 16 (CD)
      SuperGrafx
      PC-FX
      Sega Game Gear
      Sega Genesis/Megadrive
      Sega Master System
      Sega Saturn (experimental, x86_64 only)
      Sony PlayStation

      SNES and Megadrive are supported…

  2. Mednafen is **** emulator. I was forced to port install from its source code. How to assign A-button on keyboard of my macbook? How to fix wrong aspect ration? I have no mind to read long long readme to start gaming. Only thing I can do is deleting this **** ****. Thack Madnafen. The ****, RIP.
