Mednafen a multi-system emulator has been updated.

Quote:
0.9.36.1:

  • Fixed a bug that could cause an assert() to trigger under certain circumstances when the scale2x/scale3x/scale4x special scaler is used with SNES emulation.
  • PSX: Fixed a major SPU emulation regression in 0.9.36 that completely broke sample playback on a channel when the playback rate was set near the maximum.
  • PSX: Fixed noise emulation playback frequency calculation(particularly for the lowest noise playback frequencies), per tests on a PS1. It´s unlikely to have any audible effect on games, though.


0.9.36:

  • PS1: Experimental save state support(refer to the PSX module documentation for details on how to enable the support which is disabled by default).
  • PS1: Improved MDEC emulation. Fixes lockup problem in a certain corrupt copy of "Dragon Knight 4".
  • PS1: Improved SPU emulation. Fixes sound problems in "WipEout 3" and "Thousand Arms".
  • WonderSwan: Improved RTC emulation.


0.9.35.1:

  • PSX: Improved accuracy of the GPU framebuffer rectangle copy command(0x80) per tests on a PS1; fixes graphical glitches in the water effect of stage 4 of "Einhander".
