PS5PCEM 0.3.5

PS5PCEM 0.3.5

This release collects the 58 development commits after 0.3.4, plus release
packaging and installation fixes. It adds the first Linux packages, native
controller feedback on Windows, major audio corrections, shared renderer
optimizations and 15 newly documented titles.

Downloads

• Windows x64: portable ZIP and per-user installer. The launcher, runner,
  extractor and installer carry SHA-256 Authenticode signatures and timestamps
  using the same Artur Strazewicz / PS5PCEM certificate as previous releases.
  The certificate is self-signed; Windows/SmartScreen can still warn.
• Linux x64: .deb, .rpm, .pacman and .AppImage, containing the native
  GTK 3 launcher, game-run and pkgextractor. See the
  Linux installation guide.
• SHA256SUMS.txt covers all six downloadable packages. Linux packages are
  not Authenticode-signed; that signature format applies to Windows executables.

Both builds target x86-64-v3 (AVX2/BMI2/FMA) and require a Vulkan 1.2 driver.
Windows requires Windows 10 2004 or newer. Linux requires glibc 2.31+, Linux
5.11+ with FSGSBASE/Syscall User Dispatch, GTK 3, X11/XWayland and PulseAudio
or PipeWire's PulseAudio service. The AppImage uses these system runtime
libraries. Games, firmware, keys, saves and shader caches are not included.

Native Linux runtime and launchers

• Native guest execution, FS/GS switching, signal-based fault containment,
  guest threads and cooperative fibers, low-address host stacks and a Syscall
  User Dispatch guard for guest syscall instructions.
• X11 Vulkan presentation and keyboard input, including physical-key fallback
  with non-Latin layouts; PulseAudio output with stereo folding for 7.1 streams.
• Case-insensitive guest-path resolution, host memory checks and PPM captures.
• A native GTK 3 / Cairo / Pango launcher with the shared eight-language UI,
  library, settings, save browsing, PKG extraction and Vulkan diagnostics.
• Both launchers now hold 48 games, offer grid/table views and library
  search, and check GitHub Releases for updates. Version displays read 0.3.5.
• Installed Linux packages and AppImages use writable XDG settings/data
  directories. --version and --check-install support installation checks.

Linux remains experimental. The earlier WSL2/lavapipe bring-up reached the
Jets 'n' Guns 2 mission screen; it is not a native-driver performance result.
Sony HID/XInput feedback and Media Foundation video decoding remain Windows
features. The dated Windows game results below are not Linux results.

Controller vibration and LightBar

• scePadSetVibration drives ordinary two-motor feedback through native
  DualSense/DualShock 4 HID output, with XInput fallback.
• scePadSetLightBar and scePadResetLightBar now apply game-requested RGB
  colors. Coalesced updates preserve motor and color state together; pending
  HID writes retain their buffers. Close/shutdown stops motors and resets color.
• HID descriptors determine USB/Bluetooth report sizes. Bluetooth output
  handles padded reports, CRC, connection timing and LED initialization.
• DualSense USB vibration and red/green/blue LightBar changes were physically
  confirmed by the maintainer. Physical Bluetooth, DualShock 4 and XInput
  output were not revalidated. Adaptive triggers, audio haptics, microphone
  LEDs and player indicators are not implemented by this change.

Audio and media

• Independent host streams for concurrent AudioOut submissions and correct
  PCM ordering after underruns fix interrupted music/effects in Jets 'n' Guns 2.
• NGS2 PCM streaming, buffer-backed system/rack creation, custom sampler voices,
  geometry helpers and port information extend real audio processing.
• AudioOut2 keeps its clock phase; ACM convolution and valid batch completion
  fix the reproduced Subnautica startup crackle/NaN/silence chain. Clear sound
  was confirmed on repeated launches. Quake II also gains working NGS2 audio.
• AvPlayer stages decoded frames through host buffers before publishing writes
  to GPU-watched guest memory, restoring Asterix movie startup. GTA III movie
  completion no longer depends on the broken presentation-clock behavior.
• Dead Cells menu sampler playback and blended scene composition are corrected.
  Remaining discontinuities and untested titles are recorded in the reports.

Loader, firmware and extraction

• Correct SELF library-version metadata handling and standard ELF dynamic-table
  lookup fix Raiden IV's false TruncatedSelf failure without inventing tables.
• Real pthread semaphores, cleanup handlers and cancellation-state operations
  unblock Arcade Spirits, Super Woden GP and KeyWe imports.
• Fiber stack/context handling and migration, plus POSIX additions, unblock
  Arkanoid. Further Audio3d and VoiceQoS connection-attribute imports resolve.
• Direct-memory allocation preserves live mappings; POSIX startup imports and
  real file rename allow Minecraft Legends to create its LevelDB world.
• Monster Boy input polling and save startup now reach its first level.
• Large PKG metadata reads and NAPS boundary lookup improve extraction. Plain
  dump handling and observed font fallback unblock ASTRO BOT startup.

Graphics and performance

• Correct MSAA depth/stencil-only passes restore Asterix masks and remove four
  accidental whole-frame diagnostic readbacks. Proven vertex ranges avoid
  oversized sprite uploads in Dreaming Sarah.
• Fullscreen-copy shortcuts now respect blending. Reflection/cube publication,
  native texture layouts, mip/array layers, narrow 8/16-bit layouts, storage
  ownership and exact buffer publication receive correctness fixes.
• Compute wave synchronization, color conversion, M0-indexed vector moves,
  indirect register state and split texture descriptors improve shader handling.
  BVH diagnostics and compute replays improve failure visibility; they do not
  establish complete ray-tracing support.
• Shared static shader analysis, bounded scalar walks, read masks, exact
  descriptor keys, content fingerprints and smaller snapshots reduce CPU work.
• Bounded command recording and completion polling, indexed resource scans,
  reduced uploads/readbacks, reuse and parallel publication reduce host/GPU
  traffic. Changes without a demonstrated FPS gain are retained only where
  correctness checks and reduced work justify them.

Selected dated Windows measurements, Ryzen 7 7700 / RTX 3070 Ti, 1080p
output request; internal rendering stays game-controlled:

Scene	Recorded result	Scope
Asterix opening forest	46.45 → 162.20 FPS median	Matched stationary 30 s window-counter samples, October 9
Dreaming Sarah opening	53.25 → 198.25 FPS median	Final 60 s sample; later platform screen 144.35 FPS, October 10
Big Helmet Heroes menu	4.9 → 9.4 FPS median	45 s sample, October 10; stable 15 FPS not reached
GTA III opening street	8.27 FPS	30 s presented-frame sample with Bloom/Motion Blur off, October 10; not an isolated A/B result
Subnautica	14.20 FPS menu; 4.85 FPS near plant	Separate 30 s samples, October 10; not the same scene/build and not an audio-cost comparison
ASTRO BOT animated title	17.83 FPS	2,640 frames / 148.07 s, October 16; 60-frame blocks 16.08–19.75 FPS
Ghost of Yōtei tree/settings	1.27 FPS	38 frames / 30.001 s, October 13; no proven improvement or character control

These are specific development observations, not whole-game minima or new
release-wide benchmarks. ASTRO BOT's latest small optimization did not prove
an aggregate FPS gain over its previous 18.05 FPS observation. Its 20 FPS
target, GTA III's 10 FPS target and Subnautica's 30 FPS target remain unmet.
