The Team LibRetro has just updated two cores Mednafen / Beetle PSX and Sega Saturn.
The first, Mednafen, is a simple multi-system emulator that uses OpenGL and the corresponding SDL libraries, can be run via the application or used via command lines.
To run PlayStation (PSX) and Sega Saturn you have to rely on a .cue or .ccd file to open them with Mednafen to launch the games.
For the Windows builds, Windows XP or newer required. Windows 8 and newer will work, but their use is discouraged unless Mednafen is running in fullscreen mode(for video lag and quality reasons). Using the 64-bit build is recommended, for better performance and functionality.
-- 0.9.44.1: --
April 21, 2017:
MD: Added a missing MDFN_FASTCALL, the absence of which broke 32-bit x86 builds(either at link time or run time).
-- 0.9.44: --
April 19, 2017:
PSX: Restructured the GPU emulation code and data a bit to get a minor performance boost.
April 18, 2017:
VB, PCE, WonderSwan, MD, GBA: Use fastcall calling convention(on 32-bit x86) in a few (more) places where it makes sense.
April 16, 2017:
SNES-Faust: Added setting "snes_faust.correct_aspect", default value of "1".
SNES-Faust: Added PAL support.
