Project mention: Unofficial Citra (Nintendo 3DS Emulator) Fork Released: Citra Enhanced | reddit.com/r/emulation | 2021-12-29
The other idea that comes into mind, is that they were probably begged to shit about this, by armies of not so reasonable laypeople - and maybe the people here are starting to catch on that that's probably not peak human behavior. They are also very clearly aware of the demand, and still decided to not implement one. Asking, begging, pulling a Walmart tantrum, etc. isn't gonna get it done sooner either, if at all.

Project mention: Viva Pinata: Trouble in Paradise Gameplay on Xenia | reddit.com/r/VivaPinata | 2022-01-18
You could try running on the Canary branch and see if you get better performance.

Project mention: Skyline (Nintendo Switch) project update | reddit.com/r/EmulationOnAndroid | 2022-01-18
Hey there, in case you've missed it. Skyline now runs Sonic Mania (and Celeste soon) on builds from the ftx1 branch. They aren't playable just yet due to lacking crucial optimizations but will be in the coming months.

Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

Project mention: One of the biggest reasons why I love Android | reddit.com/r/EmulationOnAndroid | 2021-12-05
Unfortunately that's not even a reality on PC yet... I mean Vita3K exists but it only play about 5 percent of the Vita's library without any major bugs. Although I do hope we could get one on android one day.

Project mention: Shin Megami Tensei Digital Devil Saga appeared on PKGj, has anyone tried it? | reddit.com/r/VitaPiracy | 2022-01-21
Outside of using an actual PS3, PS2, or PS2 emulation I am not sure how else you could get it to run. There is a PCSX2 RetroArch core now that may or may not work better then the standalone PCSX2. There is also Play!

Project mention: Stadia controller to Xbox/Xinput or to Dualshock (PSNow) tools | reddit.com/r/Stadia | 2022-01-20
ViGEmBus https://github.com/ViGEm/ViGEmBus

Project mention: It's time to talk about ares (multi-system emulator) | reddit.com/r/emulation | 2021-10-14
bsnes has accuracy options so you don't have to recompile it to change the renderer (fast ppu on or off). If you use the latest nightly from here it's had backports from ares, so the emulation should be on par. The libretro core is up to date with that repo too.

Project mention: CEMU: Made an image of my TI-84 Plus CE Python, but after loading it's missing applications | reddit.com/r/ti84hacks | 2022-01-19
The main branch of CEmu does not bring over any user data. There's a USB branch which will let you send apps and programs as if there were a USB port connected to it. You'll have to build it yourself but I'm pretty sure it's this branch: https://github.com/CE-Programming/CEmu/tree/feature/libusb

I did some work on Dynarmic, so there's my bias I guess. But I def believe Dynarmic would emit better context-aware assembly than a CIL->Native jitteror the JVM would emit. Dynarmic takes advantage of instruction sets like BMI2 and AVX{2,512} and uses a pretty darn concise intermediate representation to the original ARM assembly to emit efficient x86 while a C# JIT probably still only emits baseline x86-64 and struggles with efficient vectorization of things like Arm's NEON instructions. Can't even imagine a C# or Java VM trying to automatically emit optimal assembly for an FMADD including handling NaN propagation or detecting that FMINNM can be very quickly emulated with a single vrangep{s,d} x86 instruction.

Project mention: How do I fix this gray square covering 1/4 the screen? It only happens when playing Mario kart Wii | reddit.com/r/EmulationOnAndroid | 2021-09-17
MMJ is a modified version that has better performance than stock Dolphin. You can download it here : https://github.com/weihuoya/dolphin/releases

Project mention: SNES ROM - Remove watermark from slideshow made with Lion's Slideshow Creator | reddit.com/r/romhacking | 2021-11-16
I ran his example rom in bsnes plus, a snes emulator with debugging features.
-
my recommendation is try the Xenia-Canary build; they seem to run a lot better than the stable releases, but ofc with each passing update its likely the performance has merged

To elaborate on how frequency modulation "gives the triangle wave a grittier sound", FDS's FM and Yamaha's phase modulation produce sidebands, or extra frequencies, at (harmonic * carrier frequency ± n * modulator frequency). The intensity of each sideband is proportional to FFT(carrier)[harmonic] * f(n) (for some odd f involving Bessel functions and FFT(modulator), which is zero for large |n|, and the number of nonzero n increases as the modulation index increases). In this case, the modulator frequency isn't a small rational factor of the carrier frequency, creating gritty inharmonic sidebands.
As an example of FDS FM, you can look at this video (https://www.youtube.com/watch?v=Tgu1mCBU2vA) describing FM emulation errors in older versions of FamiTracker, and how some chiptune songs are incompatible with the more accurate emulation core I imported into Dn-FamiTracker.
FDS FM is the chip's defining characteristic in modern chiptune, though it was sadly barely explored by official games in the console's original lifespan (aside from being used as vibrato). The only game I currently know which used FM at audible frequencies was Bio Miracle Bokutte Upa (https://www.youtube.com/watch?v=_alQrPMNBT0), which also required cycle-accurate console emulation and would otherwise degrade into inharmonic chaos (like the "FM emulation errors" video above). Unlike regular FM on Yamaha sound chips, the FDS allows you to use complex carrier wavetables. Combined with how the modulator is naturally slightly detuned from the carrier (due to hardware rounding errors), this results in growling evolving sounds as the waveform stretches and squeezes in the time domain, and harmonics and sidebands beat in and out of phase in the frequency domain.
Strangely, the FDS's modulator doesn't draw from an array of samples like the carrier waveform, but instead an array of 3-bit delta values (https://github.com/NovaSquirrel/Mesen-X/blob/master/Core/Mod...) representing adding [+0, +1, +2, +4, reset=0, -4, -2, -1] (modulo [-64..64)) to the current modulator amplitude. This means you have to design modulator tables carefully, or else the carrier frequency will have a net offset (as above) or even drift endlessly until it wraps around. Interestingly, FamiTracker shows the mod table as only having 32 elements (compared to the wavetable's 64 elements), and the nesdev wiki (https://wiki.nesdev.org/w/index.php/FDS_audio#Mod_table_writ...) describes the mod table as having 32 elements. This conflicts with how Mesen (https://github.com/NovaSquirrel/Mesen-X/blob/master/Core/Mod...), cxNES (https://github.com/perilsensitive/cxnes/blob/master/boards/a...), and nsfplay (https://github.com/bbbradsmith/nsfplay/blob/master/xgm/devic...) implement the mod table as a 64-element array where you can only write to 2 adjacent elements at a time. I'm not sure which is accurate, as I don't have hardware on hand to test.
Then on each sample (https://github.com/NovaSquirrel/Mesen-X/blob/master/Core/Mod...), the modulator amplitude is multiplied by the modulation strength (dropping a few lower bits and rounding oddly), clamped between [-64..192) (asymmetrical for some reason), and then used to change the carrier's instantaneous frequency by 0x through 4x (https://github.com/NovaSquirrel/Mesen-X/blob/master/Core/Fds...).
