This reduces video smoothness, but then 75Hz on a 60Hz display is not smooth either. Note that the core still runs at the ‘correct’ speed when this option is enabled – internally, the core is running the nominal ~75 frames per second, but every 5th frame is ‘dropped’. We now added a new 60Hz Mode core option, which can be used to force the core to run at 60Hz (actually 60.38Hz, but RetroArch handles this nicely via dynamic rate control). The tearing is so bad on 3DS that we would previously consider the core to be unusable on that platform…

You can experience this on Linux (when not using a compositor and without vsync forced at the driver level) and on 3DS. In particular, screen tearing is very likely to occur. This is fine if the core is run on a VRR display (or one that natively supports 75Hz…), but on regular 60Hz panels it can cause issues. No temporary buffer is required, and there is no need to actually write a save state to memory – and save states now have the correct size (~830 kb)īeetle Cygne/WonderSwanAt present the core runs at ~75Hz, matching the native refresh rate of the WonderSwan hardware. Now, the save state size is now calculated independently of regular save state creation.

Moreover, it then fails to report the actual size correctly due to a bug in the memory stream wrapper code – which means save states are always 5 MB in size. Improve save state efficiency + fix save state sizeĪt present, every time that retro_serialize_size() is called (i.e whenever save states are used), the core determines the save state size by allocating a temporary 5 MB buffer and writing into this an actual save state. We have fixed the issue by ensuring that the audio batch callback is used to send all available samples only once per frame. This ‘overstresses’ the frontend audio buffer and leads to bad AV synchronisation. Use audio batch callback only once per frameīefore, the core would upload samples in batches of ~64, which means the audio batch callback is used many (~9) times per frame.

Snes9x 2010This Super NIntendo Entertainment System emulator core has seen several improvements. When enabled, audio is more mellow/bassy, and the generated sound is closer to that produced by the ‘plus’ version – with only a negligible increase in performance requirements. We added a simple optional low pass filter at the output stage of the ‘non-plus’ core.

Apart from a substantial difference in audio emulation accuracy, probably the most obvious difference between the ‘plus’ and ‘non-plus’ versions of the core is that the latter has an inadequate level of low pass audio filtering, leading to tinny/scratchy sound.

Snes9x2005 Non-Plus: Add optional low pass audio filter.

Modified the Console Region core option to require a restart (since it has never been possible to change this at runtime…).

Fixed three memory leaks that were found in the core.

The plus core now uploads audio samples only once per frame.

The non-plus core uses an accumulator to ensure that ‘fractional’ audio samples are accounted for and sent when required.

The audio sample rate is now reported as 32040 Hz.

As a result, the core had bad audio/video synchronisation, affecting frame pacing.

Moreover, the ‘plus’ core would call the audio batch callback twice per frame, which unduly stresses the frontend audio buffer.

The ‘plus’ version of the core would send the ‘correct’ number of samples, in terms of actual emulation – but this does not tally with the sample rate reported to the frontend.

Due to integer rounding errors, the non-plus core always would send too few samples.

Neither variant of the core sent a number of samples per frame that would match the nominal expected values given by the sample rate and fps set in retro_get_system_av_info().
