Mednafen (previously known as Nintencer) is an OpenGL and SDL command-line driven multi-system Free Software emulator with many advanced features. It is distributed under the terms of the GNU General Public License.

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 at the press of a button, and are saved in the PNG file format.

Mednafen is an acronym for "My Emulator Doesn't Need A Frickin' Excellent Name."

Multi-threaded nature

Mednafen is multi-threaded in a simple manner, beyond any threads SDL creates for timers and audio, in that it handles video scaling and blitting to the video device in one thread, and actual system emulation and sound output in another thread. This setup is slightly advantageous, depending on user settings, when using SMP systems. It also simplifies program design in that emulation and sound output can easily continue uninterrupted even if a video blit takes an unacceptably long time, as is the case when synchronizing blits to vertical-blank.
