Mednafen 0.9.39.2

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.

Changelog

September 19, 2016:

  • SMS: Sanitize some previously-missed variables in the save state loading code.

 

September 18, 2016:

  • MD: Fixed a bug that caused some YM2612 state to not be restored properly on save state load.
  • MD, SMS, NGP: Fixed an old Z80 emulation bug with interrupt handling.
  • Make an index of save state sections on save state load, to detect sections in a save state that are unused by the state loading code(for debugging).
  • MD, PCE, PCE_FAST: Sanitize some previously-missed variables in the save state loading code.

 

September 16, 2016:

  • SS: Added PAL support.

September 15, 2016:

  • PC-FX, WonderSwan, NES, VB, PSX: Sanitize some previously-missed variables in the save state loading code.
  • Fixed a use-after-free bug in the SDL sound output driver.
  • NGP: Fixed several off-by-1 bugs in the address to ROM data translation function.

 

September 11, 2016:

  • Removed nonsensical unused frame advance loop in drivers/main.cpp leftover from 0.5.x.
  • PCE_FAST: Fixed a bug that could cause a crash with large "pce_fast.ocmultiplier" setting values when running CD games.

 

September 10, 2016:

  • PCE_FAST: Skip 512-byte copier header if detected when loading a ROM image.
  • PCE_FAST: Made some minor optimizations.
  • PCE, PSX, PCE_FAST: Avoid UB by biasing uintptr_t values instead of pointers directly in the CPU core.

 

September 1, 2016:

  • GB: Corrected the layer names used with the layer toggling feature.

 

August 26, 2016:

  • SS: Fixed a potential problem with SH-2 DMA event rescheduling when bus lock is held, that probably wouldn't ever happen in practice.
  • NES: Fixed several instances of missing initialization of on-cart WRAM.

 

August 24, 2016:

  • SS: Marked more functions with MDFN_COLD hint, and marked a few functions to be forcibly-inlined where it makes sense.
