\n– Asterix & Obelix: Slap Them All! \u2014 Fully playable and completable
\n– Cat Quest III \u2014 Fully playable and completable
\n– Jurassic Park Classic Games Collection \u2014 Fully playable and completable
\n
\nLauncher: eight interface languages
\n– Add Simplified Chinese, Spanish, Arabic and Portuguese alongside English, Russian, German and French. Navigation, game-library prompts, input settings, saves, preferences and status\/error messages are translated.
\n– Expand language selection to two rows, with matching click areas and room for the sound, FPS and project-information panels.
\n– Give Arabic text right-to-left paragraph direction and appropriate alignment, preserving centered buttons and the original direction of paths and key names.
\n– Preserve existing saved language IDs and restore all eight choices after a restart. Update Windows executable and installer version metadata to this release.
\n
\nGhost of Y\u014dtei: beyond the intro
\n– Restore continuous intro playback at approximately the stream’s native 30 FPS in ReleaseFast on the current RTX 3070 Ti host. Sampled movie frames take about 30\u201332 ms, without the former freeze after a few pictures.
\n– Correct Videodec2 picture fields, 256-byte NV12 row alignment, picture-specific acknowledgements and end-of-stream draining. Separate decoder instances and derive cadence from the stream so clips neither race to the end nor stall on the guest’s former 100 ms polling timeout.
\n– Advance through streamed menu-resource loading and into the animated loading indicator, Digital Deluxe Bonus, Gift of the Northern Star, Pre-order Bonus, and brightness calibration. The reference captures show readable text, confirmation glyphs, and the calibration wolf image, instruction and slider.
\n– Render parts of the interface and 3D background; the maintainer observed trees in the scene and heard menu music. Audio-library support now includes more of the interfaces bound by the title, including AudioOut2 speaker\/port state and queued-grain accounting.
\n– Unblock the menu resource catalog and asynchronous scene work, preserve compute queue ownership and completion labels, and retire validated SDK 1.1 command ranges without repeatedly replaying stranded work.
\n– Verification boundary: the complete bonus\/brightness sequence was verified on reference build 796a484. The latest renderer was checked through the intro into scene loading, but that full sequence has not been repeated on this release candidate. A complete title menu, its full animated background and gameplay are still unverified. Scene preparation and UI remain very slow: reference runs took minutes to prepare resources and seconds per UI frame. See the build-specific investigation.
\n
\nCat Quest III and Jurassic Park rendering
\n– Fix Cat Quest III’s upside-down world and intro composition while retaining the UI’s orientation. Procedural fullscreen passes preserve their UV direction.
\n– Preserve fragment coverage, alpha-to-coverage state and stencil-only passes. This removes the observed menu-text corruption and keeps language-list text visible and clipped inside its panel instead of covering it with a white fill.
\n– Implement the original AGC interpolant-mapping interface used by Cat Quest III. Adventure-selection artwork and labels, mountains and other scenery now use the correct vertex-to-fragment exports.
\n– Honor registered RGBA\/BGRA scanout formats. The captured island now has blue sea and sky and the expected character\/scenery colors instead of swapped red and blue channels.
\n– Restore Jurassic Park startup rendering, including its title logo, confirmation prompt, collection cover art and animated preview. Respect explicit color disable and DX clipping while retaining reset-depth extent recovery for Ghost of Y\u014dtei’s active HTILE-backed surfaces.
\n
\n3D shaders, materials and GPU correctness
\n– Recover pointer-backed and indirect material resources through scalar\/vector register moves, VCC offsets, restored execution masks, branches and bounded loops. Support large global texture tables and mixed sampled-image dimensions at runtime, with typed bounds and validation of malformed descriptors.
\n– Execute bounded absolute\/FLAT memory reads used by scene shaders and report the first unmapped active address. Resource recovery now follows instructions actually visited, avoiding invented bindings from inactive shader branches.
\n– Correct wave32\/wave64 masks, both words of vector conditions, SAVEEXEC operand order and SCC, unsigned carry, lane identity and cross-subgroup synchronization. Preserve DPP row\/permutation behavior and whole-quad execution.
\n– Add or correct explicit-LOD image gathers and depth comparisons, array gradients, RDNA2 sampling operands, fragment storage-image writes, BC4 and RG16 SNORM sampling, visible array-layer uploads and mixed integer exports.
\n– Preserve flat attribute channels and scalar spills. Support D16 loads into previously undefined vector registers, high-halfword stores, scene mask comparisons and bounded GDS word reads\/writes.
\n– Apply uniform HTILE clears to resident depth images, preserve stencil during depth-only clears, support matching D32 depth bias, and improve depth\/stencil barriers and compute-buffer synchronization.
\n– Retain descriptors, prepared render targets and image pins until queued draws finish using them, preventing cache eviction or command flushes from invalidating live GPU work.
\n
\nPerformance and runtime stability
\n– Cache translated graphics SPIR-V with explicit memory\/entry limits and cheaper field serialization. Reuse compatible smaller prefixes of uploaded buffers while retaining exact descriptor bounds.
\n– Cat Quest III opening-island samples improve from roughly 148 ms (~6.8 FPS) to a 124 ms median (~8 FPS) on the test host. Shader-translation work drops from about 40 to 7 ms and buffer uploads from about 124\u2013127 to 65\u201375 MiB per sampled frame. The later capture has a local co-op HUD, so this is an observed comparison of the same area, not a controlled benchmark of identical frames.
\n– Reuse prepared graphics\/compute resources and driver compute-pipeline caches; index resident sampled images by guest address and shader control flow for resource recovery. Share immutable FLAT snapshot headers and retain more small storage images within the cache budget.
\n– Prefer host-cached readback memory, cache reads of resident compute buffers, accelerate Windows x64 memory fills, and reuse swizzle offsets for volume\/MSAA copies. Reduce scene index checks and unnecessary depth readbacks.
\n– Fix Windows placeholder handling when a small guest mapping occupies the tail of a coalesced reservation, preventing the observed Cat Quest III startup HostCommitFailed. Bound permission checks to overlapping mappings and prevent thread diagnostics from suspending their own calling thread.
\n
\nValidation and remaining limits
\n– Build the launcher and runner in ReleaseFast. Exercise all eight launcher languages across settings, library, controls and saves, including restart persistence and visual checks of the four new translations.
\n– Focused checks during development cover guest-memory mapping, interpolant mapping, shader caching and Vulkan scanout\/orientation, fragment coverage, stencil\/UI and HTILE behavior. Shader changes include targeted SDK GPU probes; this does not establish correctness for every game or shader.
\n– Jurassic Park’s collection frontend still has a known AvPlayer handle-pool limit when repeatedly cycling preview videos; later previews can become static. The maintainer’s playable\/completable report concerns the games themselves.
\n– Ghost of Y\u014dtei’s full menu and gameplay remain work in progress. Other titles can still have missing graphics, stalls or crashes; consult the status document for each title’s observed milestone.
\n
\nDownloads and requirements
\n– Windows x64 portable ZIP, per-user installer, and SHA256SUMS.txt are attached to this release. Keep ps5pcem.exe and game-run.exe together.
\n– Windows 10 2004 or newer, x86-64, with a Vulkan 1.2-capable graphics driver.
\n– Games, firmware, keys and console system software are not included.
\n– These prototype binaries are not Authenticode-signed, so Windows may show an Unknown Publisher or Microsoft Defender SmartScreen warning.<\/em>
