Tengo que ver en Evolution, que lo emula pero habia texturas que desaparecian y aparecian al mover la camara. (La alfombra de la casa del prota por ejemplo)
Quizás ya va bien.

Acabará llegando, tiempo al tiempo y si pones un commit en el github, aún lo acelerarás más.

De mientras ya tenemos compatibilidad con:

Y también actualizaron el SkeletonKey que es un frontend para RetroArch con el que puedes editar playlists, jugar online y y varias cosas más, descarga aquí.

Reicast Libretro now supports MAME 7zip ROM archives for Naomi, and split/parent rom support!

RetroArch for Nintendo Switch now has built-in overclocking support! Download the latest nightlies here –

http://buildbot.libretro.com/nightly/ni ... tch/libnx/

There are 3 “Overclocking” and 3 Underclocking options.

On exit, RetroArch will restore the default system clock.
On docking, RetroArch will restore chosen clock (same with undock)
On focus loss, RetroArch will restore the default system clocks.
On focus gain, RetroArch will restore the chosen clock.

Some general performance hints:

Turn ‘Threaded Video’ on.
PSX should be fullspeed for nearly anything but a few ROM’s with 1.5GHz. Often, Boost mode should be enough.
Mupen64Plus needs a bit more juice for most games. In addition, turn off framebuffer emulation in the core settings.

iCatButler has improved many aspects of PGXP (mainly to do with ‘memory + CPU’ option), and he has also fixed some longstanding issues to do with how sprites are rendered at higher internal resolutions. Line artefacts should be considerably reduced/eliminated as a result.

Below follows an explanation by the author:

There was already a sub-texel offset applied to all the base UVs which was causing it to sample out of bounds on 2D quads regardless of the UV orientation (in hardware the error was only when the UVs were flipped).

I’ve changed it so this offset is shrunk as the scaling factor increases, which solves the problem for positive UV/XY derivatives and allows us to use the same code from the hardware renderers to fix flipped UVs.

Here is a summary of the changes made:

Add PGXP calls for instructions that were previously missed. Should improve support for games like Croc, MGS, Alundra 2 and others that rely on CPU instructions for vertex handling.
Calculate and apply offset for quads with flipped UVs earlier.
Reduce offsets applied in software renderer as resolution scaling increases (fixes line artefacts).
Calculate UV limits used for filtering earlier and pass these to the individual renderers.

NOTE: Despite the aforementioned improvements, we still find that PGXP option ‘memory only’ generally tends to be the less bug-prone solution. It’s also considerably less CPU intensive, so always keep that in mind.

CannonBall, the core running an improved OutRun Engine, has now analog axis and triggers support alongside a new 120Hz mode.

G-sync seems to react poorly with it though, so be sure to disable it if you experience audio clicks or skipped frames.

The Supermodel repository is going to be committed to Github soon. From there, we expect that we will get it in working order over the span of a week.

It will be a good Christmas this year for RetroArch fans that love the old Sega arcade games. In less than a year, Reicast Libretro has made incredible strides for arcade emulation thanks to the efforts of flyinghead, and soon Sega Model 3 will be in the bag as well!

NOTE: Supermodel will be an OpenGL-only core. No Vulkan or Direct3D 11 renderer exists for this emulator.

There are several big things brewing in the background, most of them done by natinusula. They are mostly UI-oriented.

Natinusula is working on a fancy widgets UI layer for RetroArch. This will allow us to show UI elements onscreen while the game is running. It will be far more advanced than basic simple text which is all the OSD layer in RetroArch is currently capable of displaying.

We don’t know yet if this will make the cut for 1.7.6, but we can certainly try! On top of that, natinusula has been working hard on the Ozone menu driver. Some of the things that remain to be done there is better scaling for resolutions beyond 1080p, touch/mouse integration, and thumbnails. It is our hope that once this menu driver is in a solid shape, we can replace the current MaterialUI menu for Android/iOS with this one.

Again, we have to preface this by saying that we don’t know if any of this can be achieved for the 1.7.6 release, but it is certainly something that is being prepared and it will eventually arrive in RetroArch anyway. Rome wasn’t built in a day!

What is definitely coming up, is the following:

Resolution selection (for Windows only right now, X11 support coming soon).
Will remember window position/size (for Windows only right now).
Linux ALSA MIDI driver.
Vulkan: Bugfix – ‘secondary screen in overlays not working’.
You can individually decide whether frame count, FPS and memory information is being shown.
Metal: Now supports rotation.
Wayland: Screensaver inhibit support.
F3 hotkey toggles FPS counter.

PlayStation used a special unit called the MDEC to decode full motion videos instead of relying on software rendering (like the Saturn). These videos were encoded in YUV macroblocks and had to be converted from YCbCr to RGB so that the PSX can output the final image to the screen. A common issue with PlayStation emulators is that the chroma channel generally should be smoothed, but the PlayStation tend to leave it unfiltered.

There’s now a feature called ‘MDEC YUV smoothing’ which does filter the chroma channel. You can see the before/after screenshot above (video in question is the Resident Evil 1 intro) to see the kind of visual enhancement this brings to the picture.

Some people prefer to play PlayStation1 games at native resolution and just applying a CRT shader at the end instead of running them at very high resolutions. However, there are some issues with that approach. 3D polygon graphics can tend to look very aliased and jagged and lacking in definition.

Alternatively, others like to crank the resolution up as high as possible. Both approaches have their pros and cons, but a definite disadvantage is that early 3D was very primitive so you might not want to see razor sharp angular polygons rendered at obscene resolutions, especially when a game relies a lot on pre-rendered backgrounds and other 2D elements. The Final Fantasy and Resident Evil games come to mind for one.

The option ‘Adaptive smoothing’ already exists and it attempts to distinguish 2D elements from 3D elements. It will smooth out the 2D elements but leave the 3D elements alone, resulting in a high resolution picture with the 2D elements not looking pixelated and ugly.

This new Vulkan-only option, SSAA, is a completely new approach. The image is rendered at the internal resolution you set it at (2x/4x/8x/16x, you name it). It then downsamples it at the final output stage back to a resolution somewhere in the ballpark of 240p. What you get is a low-resolution image with very clean anti-aliased 3D, kinda similar to the N64 actually which had native 8x multi sampled anti aliasing of some sort.

Certain CRT shaders expect a 240p-ish image to look their absolute best, so this option lends itself very well to that. It also can tend to look bit more coherent with mixed 2D and 3D in cases where adaptive smoothing fails.

Tip: We recommend you turn dithering off when using SSAA (Super Sampled Anti-Aliasing).

Example – Final Fantasy IX

Below you see SSAA in action with Final Fantasy IX on RetroArch. The first image is SSAA at 1x internal resolution. The second image is SSAA at 8x internal resolution. You can see how the downscaling does its magic in the second picture – it results in an image that almost looks like as if the polygon characters are part of the background itself.

Finally, a CRT shader is used – crt-royale-ntsc-320px.

PlayStation and N64 output the final image at 16 bits per color. Since that isn’t a particularly wide colorspace, both systems used dithering in order to fake the illusion of a larger palette of colors. This combats color banding and wouldn’t be very noticeable at native resolutions on a CRT TV. On more powerful hardware and when emulated, the limitations of this approach become clear, and some would prefer either internally rendering the dithering at the internal resolution, or disabling it altogether.

Dithering was previously ignored by the Vulkan renderer and was always turned off, no matter what you configured. Now it will actually let you enable it. If dithering is enabled, the scanout image will be 16 bits per color. If it is disabled, the scanout image will be 32bits. We recommend that you turn dithering off if you are going to be using ‘SSAA’ (Super Sampled Anti Aliasing)

La verdad que estan que no paran y gracias a esto varios proyectos estan tirando para adelante

No iba ni la música mp3 y daba mala imagen.
Ahora está para windows y otros sistemas porque Ghabry, uno de los desarrolladores está haciendo los cores en condiciones. Así me lo ha dicho.
Es alemán pero sabe español más o menos.

No creo que sea algo de tanto interés como el avance en emuladores. Pero es la razón del enorme avance de este core en retroarch.

Naomi GD-ROMs are now supported and this adds more than 120 Naomi games to the list of supported arcade games.
ROMs archived with 7zip as well as parent/split ROMs are now supported as well.
Another new feature is the use of per-game input descriptors: so instead of binding “Button 1” or “Axis 1”, you’ll have descriptive names such as “JUMP” or “STEERING WHEEL”. Not all games have input descriptors but more will be added in the future (and pull requests are welcome.)
In addition, many bugs have been fixed allowing many arcade games to now be fully playable: 18 Wheeler, Airline Pilot, Cosmic Smash, House of the Dead 2, Jambo Safari, Ninja Assault, Shooting Love, Virtual Athlete, Virtual On Oratorio Tangram and probably more.

On the Dreamcast front, a recent but notable improvement is the automatic setting of the BIOS date and time at boot. So you should never see the date/time setting screen again. In the same area, a new core option allows to choose the BIOS language, so you don’t have to boot the BIOS to change it.
Using the Libretro disk control interface, disk swapping has been implemented. When asked by the game, you can now virtually eject the current disk and select a new one without restarting. Some multi-disk games require this feature such as D2 or Pop’n Music 3 and 4 append disks.Another new feature for both console and arcade is the Synchronous Rendering core option. This option is only active with Threaded Rendering. When activated, it will pause the emulation thread instead of dropping a frame, which results in less dropped frames and thus a better and smoother frame rate.
Finally, Restart has been implemented so one can reset a game without having to restart the front-end.

Kronos is a fork of YabaSanshiro, which is itself a fork of Yabause. The project was started by François, his main goal was to have an emulator benefitting from YabaSanshiro improvements, while being friendly with x86_64 architecture and desktop computers.

Over time, several new features were added :

Sega ST-V emulation (the arcade version of the Sega Saturn)
Modern OpenGL Core support, it should now have a fair compatibility, even with intel GPUs, the minimum requirement is OpenGL 3.3 Core, and 4.2 if you want to benefit from gpu tesselation

Additional things to know :

It’s using a high performance SH2 cached interpreter, albeit different from the dynarecs used in YabaSanshiro, the CPU frequency requirement is still around 30% lower than an emulator using a classic SH2 interpreter like beetle-saturn
It’s compatible with beetle-saturn savefiles, there is even a core option to load them from the same path
It’s compatible with zipped cue+bin+wav isos, you don’t need to uncompress them or convert them to CHD
There are several core options to improve rendering (tesselation, upscaling, …)

Things to do/fix :

Improve compatibility with non windows/linux platforms, in the case of MacOS X we’ll first need a retroarch with OpenGL 3.3 enabled
Improve input lag, we are 1 frame behind beetle-saturn at the moment
Add CHD support
Hook optional YabaSanshiro SH2 interpreters as core options, while they are not cross-platform, they could be interesting to further improve performances on their respective platforms (x86_32,arm,arm64)
Hook alternative input devices (lightgun, mouse, keyboard, …)
Fix the “toggling fullscreen/windowed” issue (it will result in a black screen if you do that while playing)
Fix game specific issues, detailed reports are welcome at https://github.com/FCare/Kronos/issues

There is a compatibility list available here

Due to the efforts from CompCom and other members of the ModMyClassic community we are happy to announce the pre-release of the new PlayStation Boot Menu + RetroArch for this year’s Christmas holidays!

Whilst this pre-release is a working beta of a future development of BleemSync, we felt that you guys should be able to give a try and have some fun with it over the holidays.

Included in this pre-release is the Boot-Menu by CompCom, RetroArch for the PlayStation Classic and an initial batch of 91 cores. (Emulators) Please note that this is a pre-release of an upcoming module and development! This means that we are expecting some issues and shouldn’t be considered as a final release. This includes all of the 91 cores listed for the console, we haven’t had time to fully test or polish the builds for the PlayStation Classic but the majority should work absolutely fine.

Because of this, we ask you that you please notify us of any issues you encounter in our PlayStation Classic support channel in our discord here. We thank you in advance for your feedback and we will work on making improvements/fixes based on any feedback given to us.

To download and read how to use please go to: https://modmyclassic.com/?page_id=1229 for the full instructions and links.

Everyone at ModMyClassic would also like to wish you a happy Christmas and happy holidays!
