shadPS4 v0.17.0

Welcome to another big release of shadPS4. This release is the first to introduce shadnet support, which although still doesn't offer much it allows to post your online scores and share them with other players. Still you can't play multiplayer games but we are working towards to make it possible one day. Another big update is ZArchive support. Forget the 20.000 files per game you can now use ZArchive files for compressing games and having them in 1 file instead of hundreds. KosmicKrisp has also landed in the world of macOS giving much better compatibility and speed to macOS users. There are several other fixes let's cover the most important below

#### shadPS4 v0.16.0 Released

The shadPS4 team is excited to announce the release of **shadPS4 v0.16.0**, our largest update to date. This release delivers major improvements across emulation accuracy, graphics, audio, input handling, user experience, platform support, and developer infrastructure.

With hundreds of changes from dozens of contributors, v0.16.0 represents another significant step toward broader game compatibility and a more complete PlayStation 4 emulation experience.

##### Highlights

###### New Configuration System

v0.16.0 introduces the foundation of a new configuration architecture. This modernized system simplifies settings management, improves game-specific configuration handling, and lays the groundwork for future features.

The migration also includes save and trophy migration support to help users transition smoothly from previous versions.

###### Initial OpenAL Audio Backend

A major milestone for the project is the introduction of an **OpenAL-based audio backend**. This work establishes a more flexible and portable audio foundation for future improvements while continuing to expand compatibility with PS4 audio functionality.

###### Camera Support Begins

Initial camera emulation support has landed, bringing us closer to supporting titles and applications that rely on PlayStation Camera functionality.

###### Local Multiplayer Support

One of the most requested features is finally here. Multiple users can now enjoy supported games together through the new **local multiplayer infrastructure**, further expanding gameplay possibilities within the emulator.

###### Big Picture Mode

A brand-new **Big Picture Mode** provides a console-like experience designed for controllers and living-room setups. The interface includes dedicated settings integration, game folder management, and several quality-of-life improvements.

###### Screenshot Functionality

Users can now capture screenshots directly from the emulator, including support for overlays or game-only captures.

###### HTTP Library Progress

A substantial amount of work has been completed on the PS4 networking stack, with the first large implementation stages of the HTTP subsystem landing in this release. These additions improve compatibility with games and applications that depend on online communication APIs.

---

##### Graphics and Rendering

Graphics emulation received extensive work throughout the release cycle.

###### Improved Vulkan Stability

Numerous Vulkan fixes address validation errors, synchronization issues, resource destruction order problems, swapchain handling, and presentation stability. These changes significantly reduce crashes and improve reliability across a wide range of hardware.

###### Memory and Synchronization Improvements

Several fixes target GPU synchronization hazards, stale GPU memory handling, write-after-write scenarios, image layout transitions, and memory protection updates. Together these changes improve rendering correctness and reduce graphical corruption.

###### Mipmapping and Texture Improvements

A large collection of mipmapping fixes resolves texture quality issues and rendering artifacts in various titles.

###### Expanded Neo GPU Instruction Coverage

The shader recompiler and GCN decoder received major upgrades including support for:

* New VOP3P instruction definitions
* SDWA instructions
* Additional Neo-specific ALU instructions
* Float16 packed arithmetic
* Integer packed arithmetic
* Bit manipulation instructions
* New min/max/median operations
* Expanded test coverage for GCN instruction decoding

These additions improve compatibility with titles that heavily utilize PlayStation 4 Pro ("Neo") GPU features.

###### Support for combined geometry and tesselation pipelines

Support has been expanded for more advanced pipeline configurations, including additional tessellation and geometry shader combinations required by modern

Surprise! Bet you didn't expect a release from me, did you? :) Well you all asked for a miracle, and here I am, providing one. Anyways, this release is dedicated to one of our not-so-new dev, LNDF, who is responsible for a significant amount of the new GPU code, such as implementing Direct Memory Access for video memory. This isn't a solo endeavour though, there were far more updates to the emulator from the rest of the team as well, improving compatibility across well-known titles such as P.T, Driveclub, inFAMOUS, Bloodborne, The Last Guardian, Shadow of the Colossus (although this one still can't boot without hacks) and more:
