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.
SS: Fixed vertical positioning brokenness with custom "ss.slstart" setting values with interlaced video.

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.

September 11, 2016:

Removed nonsensical unused frame advance loop in drivers/main.cpp leftover from 0.5.x.

PCE_FAST: Skip 512-byte copier header if detected when loading a ROM image.
PCE_FAST: Made some minor optimizations.
