Mednafen a multi-system emulator has been updated.

Quote:
0.9.33.3:

  • Reworked the FPS calculation algorithm to produce more accurate FPS values.
  • Added a manifest file that´s embedded into the Windows executable, to ensure that noxious DPI virtualization and scaling available on Windows Vista and newer will not be used with Mednafen.
  • Added code to disable DWM composition when running on pre-Windows 8 systems, to ensure better performance and lessvideo juddering. (Sadly, it´s not possible to disable desktop composition in this manner on Windows 8 and later)
  • PCE, PCE_FAST: Added a missing ADPCM playback variable to save states; fixes the problem of severe ADPCM sound distortion when loading save states that are saved during ADPCM playback(especially noticeable with the state rewinding feature).
  • Modified MDFN_RemoveControlChars() to not kill non-7-bit-ASCII text.
  • Misc minor code cleanups and fixes for some compiler warnings.
  • NES: Fixed broken emulation of board "UNL-Sachen-8259B"(used in the game "Silver Eagle").
  • Fixed the with-drop-shadow internal text drawing routine to not draw horizontally one pixel beyond the specified maximum width in some circumstances.
  • SNES: Altered a code construct to hopefully resolve a reported compiler error with clang.
  • Error out of save state loading when the version specified in the save state is invalid.
  • Call SDL_WM_SetIcon() before SDL_SetVideoMode(), to fix the problem of the missing Mednafen icon on some platforms/window managers.
  • Fixed a minor integer overflow issue in the core PSF loading code.
  • NES: Fixed some problems in the ROM image file loading code, including a potential heap overflow vulnerability.
