ares v123 released 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:** * ColecoVision: Initialize ram to 0; fixes a crash in The Heist [Luke Usher] * ColecoVision: Disable cartridge rom mirroring; fixes Sammy Lightfoot [invertego] * ColecoVision/MSX/SG-1000: Initialize VRAM to 0; fixes various games [invertego] * Game Boy: Check window x-coord instead of only y-coord; improves the Acid2 test rom [Luke Usher] * Game Boy: Only raise STAT interrupt when display is enabled; fixes Cool Hand [invertego] * Game Boy: Implement HALT hardware bug [Meepster99] * Game Boy: Fix relationship between LY and STAT interrupt; fixes Elite Soccer, Mouse Trap Hotel, Shantae [invertego] * Game Boy: Only trigger STAT interrupts at the start of OAM search; fixes Mortal Kombat 3 [invertego] * Game Boy Color: Fix HDMA5 bit.7 reads; improves a significant number of GBC games [invertego] * Game Boy Advance: Simulate standard GBA instead of Game Boy Player; fixes GBA Video titles [Luke Usher] * Mega Drive: Implement support for Sonic & Knuckles merged roms; fixes Sonic 2K, Sonic 3K [Luke Usher] * Mega Drive: Implement support for SRAM/EEPROM when using the SEGA Mapper; fixes Demons of Asteborg [Luke Usher] * Mega Drive: Default to 'accuracy' VDP; improves compatibility at the expense of performance [Luke Usher] * Mega Drive: Optimize how often the emulator synchronises between components; offsets the cost of the previous change [Luke Usher] * Nintendo 64: Maintain Parallel-RDP as a subtree; simplifies compilation [Luke Usher] * SG-1000: Implement support for roms greater than 32KB [Luke Usher] * SG-1000: Implement support for Taiwan Type-A/Type-B mappers; fixes unlicensed Taiwan releases [Luke Usher] * SM83: Fix DAA instruction [Meepster99] * TMS9918: Implement multicolor mode; fixes various SG-1000/ColecoVision games [invertego] * TMS9918/Master System/MSX: Allow sprites to bleed off top/left screen edges [invertego] * ares: Rename lucia to desktop-ui to better represent it's function [Luke Usher] * mia: Improve N64 save-type database [jeltaqq] * mia: Add support for UNF extension, alongside UNIF and NES [Shideravan] * nall: Add macOS deployment target flags; fixes ares on macOS 10.14 [MerryMage] * ruby: Give PulseAudio higher priority than ALSA on Linux Systems; ALSA was causing frame-rate issues [Luke Usher]
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.

Update to ares v121 release.
I've released ares v121. Because it is not fully complete or stable, it is
released as source code only.
The license is now once again ISC instead of CC-BY-NC-ND.
Master System, WonderSwan, and WonderSwan Color compatibility have increased to
100%, with no remaining known bugs.
The Neo Geo Pocket is very close to 100% now with one issue remaining, where
sound effects sometimes mute in games.
Nintendo 64 compatibility has increased to above 80% thanks to corrections to
controller pak handling.
Several NES and Mega CD fixes have been added. EEPROM support has been added for
the Mega Drive.
Memory cards and paks now pre-format themselves, so you don't have to do so in-
game or in BIOS settings.
The new Neo Geo emulation is slowly improving, but it's still very preliminary
with only seven games fully playable so far.
The Nintendo 64 SM5K and PlayStation HC05 processor cores have been emulated,
but not connected yet due to a lack of information.
Added mouse input support and connected peripheral selection to the GUI, so mice
and light gun games can now be used.
There is now per-system input mapping overlays, so you can map controllers based
on the original system button names.
And lastly as promised, the SNES core has gained optional widescreen support.

Update to ares v120 release.
This release provides improved Nintendo 64 and Mega Drive emulation, plus some
emulation speedups and new features like keyboard-mapping for all Nintendo 64
controls.
The infamous Titan Overdrive demos now run with the exception of one glitched
screen each, but you will need to compile with profile=accuracy to enable the
required cycle-based VDP renderer for this to work. I'll try in the future to
support as much of it as I can with the default scanline renderer as well.

[YetAnotherEmuDev]
[This is actually the second release of v120; the change since the first release

Update to ares v119 release.
I'm releasing ares v119 today, which includes very preliminary Sega 32X
emulation support. Compatibility is currently at around 50% with the dynamic
recompiler, probably closer to 75% with the cached interpreter, and since the
system requirements were a bit too steep (on account of my Mega Drive core being
cycle/dot-accurate), I downclocked the SH2s a bit until I can speed up the
emulator more. You'll currently need about a Ryzen 5 2600 to hit 60fps reliably.
With the underclock, my Ryzen 7 5800X hits 120fps, and without it, 85fps.
Although the compatibility for the new 32X core is a bit low, this is mostly due
to pesky CPU bugs. The accuracy is quite high and I've emulated as much of the
32X and SH7604 peripheral functions as possible. I pass all 161 tests from the
Mars Check Program. It should not take much more work to reach 98% compatibility
in the future. Sega CD 32X emulation support is present, but is likely not
functional, as I haven't tested it yet.
Other major features in this release include Sega SVP support for Virtua Racing,
plus improved Nintendo 64, Mega Drive, and Mega CD emulation compatibility.
I'm going to start working on Sega Saturn emulation now, while Luke Usher works
on Neo Geo emulation. No promises as to when or if these cores will become
playable, I'm just giving you all a heads up since you'll see the skeletons for
these systems in the source code now.

Update to ares v118 release. 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. The source code has also been released under the terms of the Creative Commons BY-NC-ND 4.0 license. [Themaister]: http://github.com/Themaister/ [Luke Usher]: https://twitter.com/LukeUsher1
