ChonkyStation4 Alpha-2 is released. ChonkyStation4 is a work-in-progress emulator for the PlayStation 4 system. It can currently boot a few simple commercial games.

ChonkyStation4 Changelog:
Highlights
The PS4 system menu (VSH) now boots, but it is not functional yet
Compute shaders: DispatchDirect PM4 packet is now handled as well as async compute queues
Structured shader control flow: the shader decompiler can now recover if/else and loop constructs from shader branches
Significant GPU performance improvements: GPU-heavy scenes are now up to 2 or 3 times as fast
Basic networking: TCP and UDP sockets are now implemented. libSceHttp also works. Initial work for a PSN replacement ("ChonkyNet") has been done
Shader Decompiler
Compute shaders are now handled
Branch instructions are translated to if/else and loop blocks
Some data store (GDS/LDS) instructions are now handled
Several other instructions have been implemented
Vertex shaders without fetch shaders are handled properly
Vulkan Backend
Allow up to 3 frames in flight
Buffer/texture cache performance improvements (buffers are now tracked with page granularity)
Compute correct image size for tiled images
Fix stencil
Fix some validation errors
Other performance improvements
Integrate the NVIDIA Nsight Aftermath SDK to generate GPU crash dumps (enable via the ENABLE_NVIDIA_AFTERMATH CMake option)
Implement a basic texture garbage collector and fix other memory leaks
Basic handling of bindless descriptors
You can know select what GPU device to use through a CLI command (--gpu)
OS HLE
Several more HLE functions have been implemented for all libraries
TLS fixes
Implement/stub necessary system libraries required for VSH to boot
sceKernelDlsym and other functions for runtime loading and usage of sprx libraries now work correctly
sceNet TCP and UDP sockets are now implemented, allowing LLE libSceHttp to work
Implement sceZlib
Misc
New command line interface added - run "ChonkyStation4 --help" for more info
User management
Begin implementing a replacement PSN server ("ChonkyNet"), not public yet
Add an experimental red-zone fix patch (currently only used for CUSA00107)
