ShadPS4 est un émulateur préliminaire de PS4 pour Windows et Linux écrit en C++ créé par Shadow (d’ou il tire son nom), auteur et contributeur de projets prestigieux comme PCSX, PCSX2, PCSP, JPCSP, Arcadeflex, RPCS3…
A noter qu’un module permettant l’utilisation du Netplay est disponible ici.
Les changements principaux en résumé:
Welcome back to another shadPS4 release . It is over one month since our previous release and guess what we are back again with a lot more fixes and a lot more playable games . Rapid work has been done in different areas of the emu, but i guess the glory goes to the huge amount of GPU fixes that improved so many games, some of them are really playable now . I won’t steal the fun of discovering these, so here is a brief list of changes..
Core

– Support loading DLC as ZAR
– Reworked slot vector
– Fixed sceKernelReserveVirtualRange alignment and add ClearName
Libraries

– Decode sRGB for A2R10G10B10Srgb display buffers
– Handle QuadStrip as a triangle strip
– Add R8G8Srgb fallback to R8G8Unorm
– buffer_cache: Refactor buffer manager with sparse arenas
– Commit the emulated-LDS allocation taken from the stream buffer
– Only enable sampler comparison for comparison fetches
– Respect SPI_BARYC_CNTL front-face encoding
– Invalidate cached images after raw buffer writes
– Fixed locking behaviour for signals delivered to GPUComm thread
– buffer_cache: Rework memory tracker and implement batched uploads
– Moved on_submit callback before EndSession
– Fixed compute shader floating-point mode
– page_manager: Keep the fault probe within the faulting page
– Bind a default sampler for S# with undefined fields
– Fix sparse backing offsets, barriers, and memory budgeting
– texture_cache: Avoid associating color images with stencil
– Fixed mip layout and detiling of tiled textures
Shader recompiler
– Properly handle BaryCoord attributes on non-AMD GPUs
– Compute GDS offset dynamically instead of as compile-time constant
– Storage buffer related clean-up
– Neo: MIMG instructions

– Reimplemented B64 SALU opcodes with U64 masks
– Implemented S_MEMTIME
– Implement S_BITSET0_B64 and S_BITSET1_B64
– Skip lowering for null buffer sharps
– Implemented some V_CMPX_U64 ops
– Lower wave64 constructs for wave32
– Refactor runtime info as two tagged unions
– resource_patching_pass: Accept ds_append/consume without users
– Implement support for base vertex/instance in indirect draws
– Recognize sharp sources broadcast via V_READFIRSTLANE_B32
– Properly check for immediate args in GetRealValue
– Refactored parser to enable vertex count calculation for position only copy shaders

– Lower ballot and MBCNT as a pair
– Define SampleId for BaryCoordSmoothSample on the KHR path
– Eliminate readlanes before the tessellation and ring passes
– Read user data from the flat buffer
– Fix gradient and offset for 1D images
