This release brings in a 25% speed increase, optional frameskipping during fast forward (allowing an additional 33% max frame rate), official HD mode 7 support, SameBoy integration for 60% faster and more accurate Super Game Boy emulation, software filter support (snes_ntsc, HQ2x, Eagle, scanlines, etc), the return of mightymo's integrated cheat code database, cheat search support, movie recording and playback support, rewind support, cubic audio interpolation, 7-zip decompression support, ExLoROM board mapping support, adaptive sync support for OpenGL, and greatly improved macOS support. And if that's not enough, there's also true pixel-perfect ZSNES snow effect emulation ... seriously!
bsnes now also has an official GitHub repository with nightly builds to enable more rapid and collaborative development.
bsnes and Mesen-S now feature a new way of overclocking that comes from the NES emulation scene: inserting additional scanlines into the CPU thread, without running the video and audio during this time. The result is a method of removing slowdown in just about any SNES game, without any framerate or pitch distortion, and without harming compatibility in 99% of games (even streaming audio games such as Tales of Phantasia work as expected.)
The SA-1 and SuperFX can also be overclocked in this way. The other coprocessors (DSP-1, Cx4, etc) support HLE which results in all of their operations occurring instantly, so it didn't seem useful to add overclocking to them.

suppress Alt+F4 while in fullscreen mode
fixed every reported regression caused by the speed optimizations I've been adding recently
Y yo, 2019 y sigo usando un monitor CRT de 17'' en mi computadora, jajajaa.jeje bueno, mi monitor habitual es LCD, y la tele del salon para ver pelis tambien, solo que cuando quiero echar un vicio a emuladores necesito la sony trinitron.
Ahora seguro que los venden a precio de oro.
Yo tengo dos CRT dando vuelta. Funcionan perfectos pero ahora que recuerdo uno de ellos lo tengo que mandar a limpiar porque esta tapado de mugre por dentro. :lol:
Hay que tener cuidado con los CRT usados como dice gatuno. Siempre probar antes de comprar, por que muchos vienen con la imagen quemada en la pantalla o el zumbido de fondo (Un problema bastante frecuente con estos monitores) que suele joder y mucho
Los CRT y tengo que admitirlo, tenían su encanto. Muchos juegos antiguos se siguen viendo mejor con estos monitores que con los LCD o LED por lo que, salvo que estén rotos, nunca los descarten.
Realmente y viendo que lo retro siempre vuelve, seria genial que relanzaran nuevas versiones de estos monitores CRT (Obvio mas actualizados y con mejoras, pero manteniendo esa relación de aspecto que era nostalgica)
¡¡¡Saludos!!!

https://github.com/jeapostrophe/higan/tree/master/higan* v107.1
- don't show "Disconnect" button when "Nothing" is selected if nothing is currently connected to a port
select the currently connected peripheral (or "Nothing" if disconnected) when selecting a port from the node manager
- GTK: fix focus behavior to always work when changing which peripheral is connected to a port
disable any action on connecting an already-connected peripheral (was previously losing focus on the port connection panel)

Known issues with v0.10:
region detection is not working (PAL games are running at NTSC speeds)
Update: I posted v1.1 to address some rendering issues affecting key Super Nintendo games. Apologies, it will be a touch rocky at the start while I iron out all the kinks in the new renderers. Things should stabilize in the coming months as they did with the bsnes relaunch. Thank you!
I'm excited to release the first official version of my magnum opus software project, byuu version 1.0!
byuu is a multi-system emulator that aims to combine the accuracy of higan with the simplicity and performance of bsnes. Essentially, what bsnes did for higan's SNES emulation, I want byuu to do for all 25 of higan's emulated systems.
byuu currently emulates the Nintendo, Super Nintendo, SG-1000, Master System + Game Gear, Sega Genesis, TurboGrafx-16 + SuperGrafx, MSX + MSX2, Game Boy + Color, Game Boy Advance, WonderSwan + Color, Pocket Challenge V2, and Neo Geo Pocket + Color.
I poured my soul into this, and even for a first release, there has been substantial development. As compared to higan v107, byuu v1 features a brand-new, easy-to-use user interface in the general style of bsnes, that loads traditional game ROM images directly, supports native file dialogs, more than doubles the performance of Super Nintendo and Sega Genesis emulation, quadruples the performance of TurboGrafx-16 emulation, and provides a 20% boost to Game Boy Advance emulation. A Ryzen 5 2600 CPU should be able to run any supported system at 150fps or more. As with my other emulators, features like adaptive sync and dynamic rate control come standard.
Future plans for byuu v2+ are ambitious: I hope to add support for rewind, run-ahead, a save state manager, a cheat code editor, frame advance, screenshot capture, and much more. Possibly even a hybrid desktop + couch-mode user interface! I also want to expose my Famicom Disk System, Sega CD, and future PC Engine CD emulation to byuu. Furthermore, I hope to expand byuu beyond my own collection of emulators: specifically, I would like to offer Nintendo DS, Nintendo N64, Sony PlayStation, and Sega Saturn emulation in future releases by relying on other leading emulation projects; although I may need help in achieving those goals.
And now a heartfelt plea: I'm putting everything I have into this project, and my future in the emulation scene depends upon this project's success. Essentially, I'm getting older, and I have too many emulation cores to maintain as just one person. bsnes brought a revival to higan's SNES emulation, and I am hoping that byuu can do the same for higan's other cores.
I am looking for other developers to join on as equal contributors to this project. If this proves highly successful, I'll stick around to guide the project forward. But if not, then I will be looking for a new lead to take over the project. In that case, I would continue to periodically submit patches, time permitting, but would hope for someone else to guide byuu, higan, and bsnes forward. If neither of these two things happen by the end of this year, then my current intention is to regrettably step down from the projects, although I haven't decided on an exact date of when yet. Effectively, I've gone about as far as I could as a sole developer.
Essentially, I am hoping for this project to be what I'm remembered by after I'm gone one day, and so I want it to be as much of a success as possible. I also want these emulation cores to live on beyond me, and not just be tied to me as a person. Already bsnes and higan benefited massively thanks to 15+ years of contributions from well over a hundred volunteers. These emulators are so much more than just me. I hope to accelerate that trend, so that one day I can pass on the torch.
I hate to ask this, but anything you all can do to help promote this project would be greatly appreciated! Getting the word out about it, creating user guides and video tutorials, writing an article about it, posting about it on a forum, adding it to an existing emulation website, ... anything would help. I am hoping that in naming the project eponymously, that I can short-step some of the time-consuming struggle of establishing a new emulator project, but word of mouth is still vital for people to know that this project exists.
Thank you all so much! I hope you'll enjoy this new software as much as I've enjoyed making it.

It took 22 years, but they finally found my one weakness, and they've won. I tried everything.
I tried acknowledging and addressing all criticisms made of me for the past two years now to no avail.
I tried making the software everyone wanted, running a GitHub account, and more, to no avail.
I even tried changing my name, and later my emulator name, to no avail.
Decir que a la emulacion todavia le queda mucho porque quizas unos juegos 3D de megadrive tengan algun problema con los graficos, creo que no es justo.
It is my privilege to release ares v117 today.
Most notably, this release adds Sony PlayStation emulation. Please understand however that this support is new, and compatibility will be low. That said, the base hardware is entirely emulated, including MDEC, SPU, CD-XA, memory card support, etc. It shouldn't take much effort to raise the compatibility to a respectable level in the future. And thanks to dynamic recompilation and multi-threading, it should run at full-speed even on modest hardware. ares can run games in either ISO/CUE or BIN/CUE format, as split/WAV files or as a single merged BIN file.
As for the Nintendo 64, Themaister has ported Parallel-RDP to it, and it too is now capable of running commercial games at full-speed, with accuracy just shy of Cen64. However, the support is too new and untested to release at this time, and memory card support has not been added yet. Nintendo 64 support should ship with the next release instead.
Beyond this, there are six months of emulation improvements: many new Famicom mappers were added, several Master System and Game Boy Advance emulation bugs were fixed, etc. Also, a second virtual gamepad has been added for multi-player support.
[Nintendo 64] ParaLLEl-RDP renderer added to ares. Uncapped speed => 130-200fps. CPU accuracy is very slightly lower than Cen64. RDP + VI is as accurate as angrylion. (https://twitter.com/near_koukai/status/1360956749847519233)
I'm excited to launch ares v118 today, the first release featuring playable, full-speed Nintendo 64 emulation!
The new Nintendo 64 emulation is made possible thanks to Themaister very graciously porting his Vulkan-based ParaLLEl-RDP graphics renderer to ares. With its default settings, it is nearly pixel-perfect to real hardware, and it optionally supports upscaling to 2x or 4x the original Nintendo 64 resolution, plus optional supersampling back down to the original resolution (for enhanced anti-aliasing) if desired. The Vulkan support requires an appropriate graphics card, and either Windows or Linux. At this time, Vulkan is not available for macOS nor the BSDs.
Also new for the Nintendo 64 core in this release is Rumble Pak, Cartridge Pak, SRAM, EEPROM, and Flash save support. Note that for right now, the Rumble Pak will only be enabled for games which use internal saves (SRAM, EEPROM, and Flash.) That does not cover all Rumble Pak-capable games. The option to choose between Rumble Paks and Cartridge Paks will be added to a future release.
For the PlayStation core, Luke Usher provided two rendering fixes that allow Final Fantasy VII and Tony Hawk's Pro Skater to be fully playable!
Right now, approximately 33% of the Nintendo 64 library is fully playable, and about 67% of the PlayStation library is fully playable. Each core has only been under active development for about one month each, so they both have a long way to go. Please treat these early releases as tech samples, rather than finished emulation cores.
Further, note that the Nintendo 64 and PlayStation cores employ cached interpreters. This is a middle-ground between the accuracy of interpreters and the performance of dynamic recompilers. As such, ares' system requirements will be a bit higher than traditional emulators for these systems. Presuming no background task interference or CPU throttling, generally speaking, a Ryzen 5 2600 or better CPU should get you to around ~120fps in the average case, and ~60fps in the worst case.

ares v122 released
This release primarily provides improved Neo Geo Pocket/Neo Geo Pocket Color and Sega 32X emulation.
The entire Neo Geo Pocket/Color library is now thought to be playable, with minor graphical issues in four titles.
A small number of SEGA 32X games are now playable, although most still experience graphical and/or audio issues.
ares v123 includes significant improvements to the emulation of the ColecoVision, SG-1000 and the Game Boy/Game Boy Color.
This release brings the compatibility rating for ColecoVision and SG-1000 to four stars.
This means that we have 100% compatiiblity with both of those libraries, with the only exception being the few games that require additional peripherals (driving controllers; touchpads, etc).
The Game Boy improvements are significant, but not quite enough to increase the compatibility rating at the present time, even so, Many more games are playable than before.
Finally, a few tweaks to MegaDrive emulation have improved compatibility, reduced the occurance of video corruption, and improved performance of the Sega 32X emulation.
Changelog:
- fc: implement GTROM mapper [LukeUsher]
- hiro: track window focus via messages, not polling [invertego]
- mia: prefer known rom extensions in zip archives [invertego]
- ms/sfc: fix some light-gun related crashes [invertego]
ares v126 brings even more improvements to the NES/Famicom emulation by adding support for many more rom mappers. Compatibility for MSX1/MSX2 has also improved as a result of adding heuristics for better mapper detection.
An issue that prevented Windows users from mapping inputs in v125.1 has also been fixed.

Rasky ha estado trabajando duro para mejorar la emulación de N64; asegurándonos de pasar tantas pruebas como sea posible en la nueva ROM de prueba para el sistema; después de mucho trabajo, ahora pasamos casi todas las pruebas; más que cualquier otro emulador de Nintendo 64 existente actualmente.
Aunque la compatibilidad no es tan alta como la de otros emuladores, la mayoría de los juegos funcionan y creo que es seguro decir que ares es el emulador de Nintendo 64 más preciso en el momento de la publicación; basado en estos resultados de prueba, así como en la jugabilidad.
This is an emergency hotfix release for macOS and Linux users that fixes the following issues
- N64, PS1 and 32X emulation crashes on Intel macs running macOS versions newer than Catalina. Unfortunately this slipped through the net because it was functional on Catalina, which I have, and the latest macOS on M1, which Rasky has.
- For Linux users, some Audio/Video/Input driver options were missing, due to broken dependency resolution.
- Additionally, one minor emulation fix did get merged: the Copyright screen on Perfect Dark now renders using MAME RDP. (This is not yet fixed when using Parallel-RDP, as we are still working on getting it fixed upstream)
- macOS users on Apple Silicon/ARM64 platforms, and Windows users can safely skip this update if they wish to do so.
Build System
- Fix broken package detection after the switch to pkg-config [LukeUsher]
Nall (Standard Library)
