Mednafen 0.9.46

Description

Mednafen is a portable, utilizing OpenGL and SDL, argument(command-line)-driven multi-system emulator. Mednafen has the ability to remap hotkey functions and virtual system inputs to a keyboard, a joystick, or both simultaneously. Save states are supported, as is real-time game rewinding. Screen snapshots may be taken, in the PNG file format, at the press of a button. Mednafen can record audiovisual movies in the QuickTime file format, with several different lossless codecs supported.

The following systems are supported(refer to the emulation module documentation for more details):

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

Mednafen is distributed under the terms of the GNU GPLv2.

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.

August 7, 2017:
- Use a sorted std::vector instead of std::multimap to store current settings, to reduce memory usage.
