Mednafen is a portable, utilizing OpenGL and SDL, argument(command-line)-driven multi-system emulator with many advanced features. The Atari Lynx, GameBoy, GameBoy Color, GameBoy Advance, NES, PC Engine(TurboGrafx 16), and SuperGrafx are emulated. 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 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.

 

Mednafen was previously known as "Nintencer", a NES emulator which is somewhat less CPU intensive and will run on machines without OpenGL capabilities. Downloads of Nintencer will remain on the "Releases" page, and the old Nintencer branch may periodically be updated with fixes for critical bugs.

September 20, 2005 - Mednafen 0.3.1 Released

Mednafen 0.3.1 and the Win32 binary executable package are both now released. Enjoy the insanely slow PC Engine emulation!

 

 

Fixed a bug that existed since 0.2.0 that was causing a null-pointer deference in stat().

Interesting, glibc silently ignored the error, but the error caused crashing under Windows.

 

PCE:  The HuC6280 timer latch is now loaded with an appropriate value on reset.  Fixes

"Double Dungeons".

 

PCE:  Added generic PC Engine save RAM emulation.

 

 

 

Update:

 

After realizing the PC Engine sound emulation code is much slower than I thought it was, I've rewritten it to be much faster, at about the same sound quality. Expect a release incorporating this new sound code later this week, after I do bug testing.

NPlayers.ini fills the "Players" column of your favourite MAME frontend letting you know how many players the game supports and if it's simultaneous play or not. You'll find more info in the text file included in the zip archive.

 

18-09-2005 - Ready for MAME 0.100! Users of EmuLoader v4.7.2 or newer should place nplayers.ini in "ini_files\" folder.

You can get the file here.

VBA smooth v6.4

 

feature added:

- add an entry forceRenderMethod=1 in vba.ini to force using DirectDraw driver (thanks awi's suggestion)

- force to stop emulation before switching sound emulation on/off

- add an entry saveMoreCPU=1 in vba.ini for slow computer to save more CPU power

 

bug fix:

 

[mikoxc] when sound is disable, vba load a game then crashed

- fix a bug in PCM interpolation module

 

[mikoxc] VBA run a game with sound disable, after load a real-time save file, VBA crashed

- fix another bug in PCM interpolation module

 

[bohdy] 6.3 still runs at half framerate in automatic mode, just like if frameskip 1 was selected.

- fix a bug in automatic frame rate control

 

[squaresoft74] On the top and left sides of the screen i get blue lines that weren't there with previous builds.

- not crop a pixel around the border of output image.
