Mednafen 0.9.36 [message #3539] Thu, 19 June 2014 01:14 Go to next message
Administrator  [PM]
0.9.36 contains a major PS1 SPU emulation regression that may break sound effects(and less likely music) on some games. The regression is fixed in 0.9.36.1



Highlights of this release include:
  • 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.


Changes since 0.9.35.1

There seems to be something wrong with the win64 build, the emu runs slower and the sound crackles, at least on psx games. The win32 build appears to be unaffected and works fine.
If it helps, I'm playing on a Windows 7 x64, and the previous version worked perfectly.

Anyway, thanks for the great emu.

Are you using any sort of power management/CPU frequency scaling software, or running a ton of programs?

That CPU should be fast enough, and the 64-bit version should be faster than the 32-bit version. I do compile the 64-bit version with "-mtune=amdfam10", and tuning can sometimes turn minor changes in code to major performance changes when running on a non-targeted architecture...

I redownloaded the 64bits version and now it seems to be working as expected. I probably modified something I shouldn't have while configuring it before. Embarassed

sorry for the inconvenience and thanks again

I'm wondering: apart from the memory card problems mentioned in the documentation, is there any other reason why save states are currently experimental? Are there other potential problems that could arise from using them in the current version?

PS1 save state support is considered experimental because it's new and could have unforeseen bugs, and currently doesn't work properly when used in the debugger's step mode.

They're not disabled by default because they're considered experimental per-se, but to make sure the userbase understands the potential consequences of reckless save state usage.
