ProsperoLight 01.000.110

Stable: Punktfunk hosts, more box art, no wait before the stream

New

• Punktfunk hosts: the decoder now reserves six pictures by default, so Punktfunk's GameStream stream (five reference frames) decodes on a release build. Before, it showed no picture. Streams from other hosts are unaffected.
• JPEG and WebP box art: covers that hosts such as Punktfunk pass through as JPEG or WebP now appear, as PNG covers always did.
• PyroWave from punktfunk: punktfunk's PyroWave revision is accepted; its shaders and bitstream code are the same as the supported one.

Changed

• No wait before the stream: the check for a newer version runs on its own. When homebrew.page could not be reached, starting a stream, a home-screen forwarder included, waited about a minute for that check to give up.
• Box art: covers over 1 MiB load, and covers already fetched are kept in memory, so scrolling back through a large library does not download them again.
• Built on ps5-opengl SDK 1.0.2.

Installation / update

Title ID remains PPSA99002; saved PCs, settings and pairing are kept. Close the app before updating. Extract PPSA99002.zip and copy the complete PPSA99002/ folder to /data/homebrew/. Keep only one installation for this title. SHA256SUMS verifies the download.

ProsperoLight 01.000.100

Stable: a home-screen tile for each PC game

New

• Home-screen forwarders. A separate tile on the PS5 home screen can now start one PC app or game directly. The tile opens ProsperoLight with --pc, --app and --exit-after-stream; ProsperoLight shows its connecting screen at once, with no opening animation and none of the launcher's pages, and goes straight into the stream. If the PC is off, not paired or has no such app, the launcher opens and says why. Tiles are made with tools that follow the PS5 Forwarder Format, such as Forwarder Manager. See docs/FORWARDER.md.
• A list for forwarder tools. The saved PCs, their apps and box art are kept under /data/prosperolight/forwarder, so a tool can let you pick a PC and an app instead of typing their names.
• Start-up timing in the diagnostic log: how long system modules, the decoder warm-up and storage take before the first frame.

Changed

• Stop app tells the truth. When the PC accepts the stop but keeps the app running, the launcher says so instead of "App stopped", and starting another app explains why it cannot.
• Launch background: the picture the console shows while ProsperoLight loads is now a plain dark gradient in the connecting screen's colours. The home-screen background is unchanged.
• PyroWave: the app's high-frame-rate declaration is read from the folder the app runs from.
• Updated the bundled PS5-Lapy-JB-Daemon helper.

Installation / update

Title ID remains PPSA99002; saved PCs, settings and pairing are kept. Close the app before updating. Extract PPSA99002.zip and copy the complete PPSA99002/ folder to /data/homebrew/. Keep only one installation for this title. SHA256SUMS verifies the download.

Note

The new launch background appears once ProsperoLight is registered again: remove its old registration from the PS5 home screen, then let ShadowMountPlus register the app. Everything else works without this step.

ProsperoLight 01.000.095

Stable: improved frame pacing and unified stream overlays

New

• Live frame graph in the statistics overlay.
• Hold Circle to close the app from the PCs screen, with a progress bar and translated hint.
• Escape key on the streaming keyboard.
• Extended diagnostics: timed traces and frame-interval reports, controlled by the existing diagnostic logging switch.

Changed

• Frame pacing and VRR: reworked fixed-refresh output, low-FPS repetition, cadence recovery and refresh-rate transitions. H.264, HEVC and PyroWave now share the scheduling policy.
• VRR compatibility: updated the app declaration for older firmware, including system software 6.02.
• Stream overlays: PyroWave now uses the same statistics and keyboard presentation as H.264 and HEVC. Fixed missing PyroWave overlay content and incorrect refresh-rate formatting.
• Decoder settings: hidden the Classic/Adaptive and CPU-core controls. All configurations now use Classic with 3 cores; experimental implementations remain available for development.
• App libraries: removed the 64-app limit and bounded poster texture caching for large libraries.
• Added a catalog fallback when homebrew.page cannot be reached.
• Added compiler caching and signed build provenance. Releases now contain only PPSA99002.zip and SHA256SUMS; disk images are no longer distributed.

Installation / update

Title ID remains PPSA99002; saved PCs, settings and pairing are kept. Close the app before updating. Extract PPSA99002.zip and copy the complete PPSA99002/ folder to /data/homebrew/. Keep only one installation for this title. SHA256SUMS verifies the download.

Warning

Re-register ProsperoLight after updating to enable the updated VRR support.
Remove its old registration from the PS5 home screen, then let ShadowMountPlus register the app again. Otherwise, the console may continue using the old VRR declaration.

ProsperoLight 01.000.090

Beta: updates from the app, 31 languages, PyroWave, more of the DualSense

Everything in beta 01.000.080 is included.

New

• Updates from the app. When homebrew.page lists a newer release, a dialog offers it.
  Update now downloads, checks and installs it, and ProsperoLight closes while its files
  are replaced; What's new shows the release notes first. This is the first release that
  can do it: coming from 01.000.080, install this one by hand once.
• 31 languages. The launcher follows the console's language, or the one chosen in
  Settings. Many texts were adapted from Moonlight Qt and the rest were written for
  ProsperoLight; they have not been reviewed by native speakers, so corrections are welcome.
  Long texts scroll slowly instead of being cut.
• PyroWave. A GPU wavelet codec decoded with Vulkan, chosen in Settings with 4:2:0 or
  4:4:4 chroma and SDR or HDR10. It needs a Vibepollo/Vibeshine host that offers it and a
  wired network; the bitrate slider reaches 1000 Mbps while it is selected. It was
  contributed and tested by its author; we could not test it on our own host.
• More of the DualSense reaches the game: adaptive triggers, light bar, motion, touchpad
  contacts, and haptics from hosts that send them.
• Frame rate: 30, 60, 90 and 120 FPS, or Custom for any rate from 30 to 120.
• Frame pacing: Unpaced (the default, as before), Paced and Paced+VRR.
• Settings for each PC: mute the PC's speakers, let the host optimise the game, quit the
  host app after the stream, and optional Vibepollo requests (VRR, virtual display, scale).
• More switches in Settings: menu sounds, diagnostic logs, and a six-picture decoder
  slot for hosts that need it (off by default).
• Two more stream shortcuts: Touchpad + L3 and Touchpad + R3 send the host's Back and Guide
  buttons.

Changed

• Starting a stream. The launcher fades to black and the stream shows one connecting
  screen. The television often changes its mode at that moment, and the change used to cut
  the connecting screen in two.
• Access to /data/prosperolight now comes from the upstream PS5-Lapy-JB-Daemon helper,
  started for this app only, and works on more firmware versions. The app no longer carries
  its own elevation code.
• Fixed a slow drift between the host's frame cadence and the console's, stalls while
  PyroWave pictures were processed, and the connecting artwork at 4K.
• A matching V-Sync frame is shown as soon as it is ready.
• Every file in the release ZIP is stored open to all (0777), as the console expects of an
  app; a tool that keeps a ZIP's permissions no longer leaves an app that cannot start.
• Box art is decoded by libpng.
• Releases carry the app folder as a ZIP and a raw exFAT image; the compressed .ffpfsc image is no longer published, to prevent compatibility issues with
  the in-app update worker and ProsperoStore, which install from the ZIP.

Known

• On one test console the system crashed once when the app was closed after several
  120 FPS streams. It did not happen again; please report it if you see it.

Installation / update

Title ID remains PPSA99002; saved PCs, settings and pairing are kept. Extract
PPSA99002.zip and copy its PPSA99002/ folder to /data/homebrew, or use the
raw image PPSA99002.exfat. Keep only one format installed for the title. Close the app before replacing its files, then restart ShadowMountPlus or the
console. SHA256SUMS covers every download.

Thanks

frame matching, the six-picture slot) and everyone who reported results.

ProsperoLight 01.000.080

Beta: a new launcher, four controllers, files that survive updates

Everything in experimental beta 01.000.070 is included; its notes below
still apply to the stream itself.

New

• A new launcher. It is drawn by the GPU with the widgets of
  ps5-homebrew-ui, at
  up to 4K, in ProsperoLight's own Moonlight theme: frosted panels over a
  night-blue sky. Four tabs: PCs, Games, Settings, About.
  • PCs. Every saved PC is on screen with its state: ready, needs pairing,
    or offline. The panel beside the list shows its address, port, pairing, app
    count and running app. Remove must be held; Unpair asks first.
    Triangle searches the network again.
  • Games. Box art is shown as posters and the list scrolls. The selected
    app's name is the headline, the page takes its colours from the poster, and
    the running app carries a badge.
  • Settings. Rows are grouped, left and right change a value, and bitrate
    is a slider from 10 to 300 Mbps. At 4K a meter shows the bitrate against
    the decoder's measured limit.
  • About. Credits, the version, three steps to get started, and the
    folders the settings, the pairing and the logs are in.
  • Address and port are typed on a number pad inside the launcher.
  • The screen keeps moving while a PC is slow to answer.
• Sounds. Every widget has its sound: moving, choosing, tabs, sliders,
  dialogs, notices, and starting a stream.
• Up to four controllers. Every user signed in on the PS5 plays with their
  own controller. Turn on another controller, choose a user for it when the PS5
  asks, and it joins as the next one, before or during a stream. Touchpad + L1
  (leave the stream) and Touchpad + R1 (statistics) work on every controller;
  mouse mode and the stream keyboard stay with the first one.
• Sunshine port per PC. The PCs page has a Change port button, and
  Add a PC accepts address:port. A PC found on the network uses the port
  Sunshine advertises.
• One folder for everything the app writes. When it starts, ProsperoLight
  asks the console's ELF loader for access to the filesystem, the way
  ProsperoEden does. Saved PCs and settings are then in
  /data/prosperolight/config, the pairing in /data/prosperolight/pairing,
  and the logs in /data/prosperolight/logs. An update or a reinstall does not
  touch them, and the first start brings the settings and the pairing over, so
  nothing is paired again. With no ELF loader on port 9021 the app uses its own
  storage as before.
• One connecting screen. The launcher's connecting screen stays on the
  television while the stream connects, its bar moving with each step; when the
  first picture arrives the bar runs to its end and the screen fades into the
  stream. Touchpad + L1 still cancels.
• New version notice. Once per launch the app asks the homebrew.page
  catalog whether a newer ProsperoLight is listed, and says so in a notice that
  stays for ten seconds. Nothing is downloaded or installed.
• Crash report. If the app faults it writes logs/crash-last.txt;
  tools/symbolize-crash.py names the functions.
• The stream shortcuts are named after their button. They were written
  Select + ...; the button is the touchpad, so they are now Touchpad + L1,
  Touchpad + R1, Touchpad + Square and Touchpad + Triangle. The shortcuts
  themselves did not change, and buttons are shown as glyphs.

Fixed

• No black screen when the app opens: the console's splash picture stays until
  the launcher has drawn its first frame.
• The launcher no longer stands still for a second every few seconds (its log
  is written by a thread of its own).
• Stopping a running app from the launcher no longer closes ProsperoLight.

Good to know

• The app file grows from 5 MB to 32 MB: the launcher brings the ps5-opengl
  runtime, and the update check brings libcurl. The app folder has one more
  file, sandbox-elevator.elf, the helper the ELF loader runs.
• Opening the app takes about five seconds; the splash picture covers it. After
  a stream above 60 Hz or in HDR the screen stays black for five seconds before
  the launcher returns, while the television changes mode.
• PC and app names can use western and central European letters and Cyrillic.
  Other scripts are not drawn yet.
• Saved PCs and settings from earlier versions are kept. Going back to an
  earlier version resets them; pairing is kept.
• pairing/key.pem under /data/prosperolight is what lets this console
  connect to a paired PC: keep it private.

What was tested

On a PS5 with a 4K television: the launcher and its four tabs, filesystem
access and the move of settings and pairing to /data/prosperolight, the
connecting screen handed to the stream, a stream and the return to the
launcher. On the PC: the launcher's screens and logic against a pretend
Sunshine network, and the unit tests.

ProsperoLight 01.000.070

Experimental performance beta — new decode and presentation threads

This is a prerelease, not a replacement for stable 01.000.060. It
supersedes beta 01.000.062.

• Decoding and presentation now run on separate threads. Decoding no longer
  waits for a flip, and every display refresh shows the newest decoded frame.
• A stream that outruns the decoder keeps playing at the decoder's pace. The
  rule that showed one frame every 100 ms once decoding fell behind is removed.
• Stream threads are kept off the CPUs reserved for the decoder, and the video
  receive thread has a CPU of its own.
• The flip wait uses flip events instead of polling or waiting for a vblank.
• The overlay separates network, decoded and displayed frame rates, and frames
  lost on the network from frames discarded because decoding fell behind.
  Decode time covers the last second (mean, 95th percentile and load).
• New settings: V-Sync (Off flips immediately and tears), Decoder
  pipeline (Classic by default; Adaptive is experimental) and Decoder CPU
  cores (3 by default; 4 and 5 are experimental).
• Bitrate presets gain 50, 60 and 70 Mbps.
• A failed stream now says whether the connection was lost while streaming or
  never completed, with the stage and the error code.
• moonlight-common-c is updated, and the performance summary is also written
  to klog.

Know the bitrate limit

The PS5 decoder, not the network, limits the usable bitrate, and this beta
does not raise that limit. Measured at 4K HEVC: smooth up to 80 Mbps at
120 FPS and about 115 Mbps at 90 or 60 FPS; above 100 Mbps at 120 FPS and
145 Mbps at 90 FPS the stream freezes about once a second. The table and chart
are under Bitrate limits.

What was tested

Run on one PS5 with one NVENC host at 4K, 120 FPS, HEVC SDR, with both decoder
pipelines. 1440p, 1080p, 60 and 90 FPS, HDR, H.264 and V-Sync Off use the same
code but were not re-run on a console for this beta. The Adaptive pipeline had
one defect fixed after its last console run; leave it on Classic unless you
want to help test it.

Please report your results

Use GitHub issues and include:

• PS5 firmware; Sunshine/Vibepollo version; host GPU and driver.
• Codec/HDR, resolution/FPS, bitrate, stereo/5.1, Ethernet or Wi-Fi.
• The three new settings, and whether this beta is smoother, unchanged, or
  worse than .062 or .060 in the same game.
• With the overlay on (Select+R1): the "Decoder", "Decode (last second)" and
  both "Frames dropped" lines.
• If available, attach performance-last.json and performance-frames.csv from
  the app's /download0/moonlight/ save directory. These are overwritten by the
  next stream; the console may expose them inside the title's UFS2 download0.dat.
  Do not upload the entire save image: it may contain pairing credentials.

Installation, update and rollback

Title ID stays PPSA99002. Choose PPSA99002.ffpfsc, or extract
PPSA99002.zip and copy its PPSA99002/ folder to /data/homebrew.
Do not keep both formats installed. Close the app before replacing files, then
restart ShadowMountPlus or the console. SHA256SUMS covers both downloads.
Existing pairing and settings are retained. To roll back, replace the beta with
the corresponding .062 or .060 download and restart ShadowMountPlus or the
console.

make ffpfsc FEC_SIMD=1 OPUS_SIMD=1 PERFORMANCE_DETAIL=1 FLIP_POLL_US=200 INPUT_POLL_US=2000 VIDEO_SLICES_PER_FRAME=8.

ProsperoLight 01.000.062

Experimental performance beta — help test 4K120

This is a prerelease, not a replacement for stable 01.000.060.
Improved decode headroom; remaining 4K120 stuttering is under investigation.

• Requests eight slices per frame for increased decoder parallelism. Local HEVC
  tests confirmed eight slices and lower decode times, including comparable
  compressed-frame sizes. Gameplay windows included Windows/RDP login transitions:
  these are promising observations, not a controlled percentage improvement.
• Shortens input polling to a 2-ms target and accounts for polling work time.
  This does not establish a measured input-to-photon latency reduction.
• Enables CPU-feature-checked FEC SIMD and Opus SIMD, with 200-us flip polling.
• Reduces repeated GPU cache-flush work and avoids heap allocation for common
  socket polls. Preserves bounded presentation overlap and source ownership.
• Includes local performance summaries and bounded per-frame timing records for
  diagnosis. No streamed images, typed text, or automatic remote telemetry.
• Includes PC removal/re-pairing improvements for changing host software.

Decoder depth stays one, worker affinity/priority remain unchanged, every
decoded picture remains eligible for presentation, and experimental pacing and
audio-backlog dropping are off. No host configuration is modified. Eight
slices may behave differently with other encoders/codecs; report regressions.
Higher bitrate is not higher FPS, and sustained 120 FPS is not guaranteed.

Please report your results

Use GitHub issues and include:

• PS5 firmware; Sunshine/Vibepollo version; host GPU and driver.
• Codec/HDR, resolution/FPS, bitrate, stereo/5.1, Ethernet or Wi-Fi.
• Game and whether this beta is smoother, unchanged, or worse than .060.
• Complete Windows/RDP login first, reconnect, then warm up for 30 seconds and
  play the same area for two minutes. Return with Select+L1 and close the app.
  Separate login/menu/teardown time from gameplay. Stop early if unusable.
• If available, attach performance-last.json and performance-frames.csv from
  the app's /download0/moonlight/ save directory. These are overwritten by the
  next stream; the console may expose them inside the title's UFS2 download0.dat.
  Do not upload the entire save image: it may contain pairing credentials.

ProsperoLight 01.000.060

Smoother 4K120 streaming

• Enabled bounded decode/presentation overlap: the next picture can decode while
  the previous native flip completes, with at most one outstanding submission.
  Source surfaces and shared GPU memory remain protected until completion.
• Improved stale-frame handling, short-window FPS metrics, and fractional-refresh
  negotiation (for example, a 120 FPS request on 119.88 Hz output).
• Added a small local post-session performance summary and regression checks for
  presentation ownership, timeout handling, and incomplete report writes. No
  remote telemetry or streamed content is collected by this summary.

4K120 before / after

One paired Hollow Knight test on PS5 firmware 6.02, using wired Ethernet,
3840×2160 at a requested 120 FPS, HEVC SDR, 80 Mbps, stereo, and 119.88 Hz output:

Measurement	Before: overlap off	After: overlap on
Decoded / presented frames	16,769 / 12,686	14,058 / 14,058
Stale presentation skips	4,083 (24.3%)	0 (0%)
Mean enqueue-to-decoder-callback wait	5.468 ms	0.016 ms
Sampled pending video queue peak	5 frames	0 frames
Mean decoder-call time	6.869 ms	6.934 ms
p99 CPU-observed completion interval	75.499 ms	31.499 ms

The tester reported lots of stuttering before and much smoother playback
after. Neither run reported network frame gaps or audio errors. The improvement
is in queueing and presentation, not faster hardware decoding.

These are whole-session measurements from one comparison, including startup and
menus, with different session lengths. The baseline was instrumented with overlap
disabled, not the exact public 01.000.055 binary. This is not a guarantee of
locked 120 FPS, lower input-to-photon latency, or a fix for every high-bitrate/Wi-Fi
setup. CPU-observed frame age increased from 12.560 to 16.854 ms; overlap changes
when completion is observed, and the baseline excludes skipped pictures from
that metric. It cannot establish an end-to-end latency change.

See the Round 2 measurements and methodology.
Further performance work is deferred to the next version: FEC SIMD, Opus SIMD,
audio catch-up, and shorter flip polling are not enabled in this release.

Installation / update

Title ID remains PPSA99002; existing pairing and preferences are preserved.
Choose PPSA99002.ffpfsc or extract PPSA99002.zip and copy its PPSA99002/
folder to /data/homebrew. Do not keep both formats installed for the same
title. Close the app before replacing its files, then restart ShadowMountPlus
or the console. SHA256SUMS covers both downloads.

ProsperoLight 01.000.055

• Added a persistent Stereo / 5.1 surround setting.
• Added Moonlight-compatible 5.1 Opus negotiation and PS5 eight-channel AudioOut,
  with the unused side channels silenced and automatic stereo fallback when the
  surround port is unavailable.
• Compacted the Settings rows so all seven controls and the shortcut note remain
  visible above the footer.
• Replaced the temporary demo app cards with a clear loading state while the
  Sunshine application catalog refreshes.
• Unified the mbedTLS structure configuration across the C and C++ stream code,
  preventing identity initialization from overwriting the live PS5 pad state.

ProsperoLight 01.000.050

Changelog

01.000.050

• Added independently selectable 90 and 120 FPS streaming at 1080p, 1440p,
  and 2160p, with native 4K/119.88 Hz output validated on PS5 hardware.
• Preserved native 4K presentation for high-resolution HFR streams and restored
  the launcher output cleanly when a stream ends.
• Added an application-side startup transition for TVs that resynchronize when
  an HFR-capable title opens.
• Moved Sunshine discovery behind the first rendered launcher frame for faster
  visible startup.
• Documented that HFR setting changes should be applied before launching, or
  followed by stopping and relaunching the active Sunshine application.
• Clarified that wired Ethernet is recommended for high-resolution and HFR
  streaming.
• Added guidance to tune bitrate per configuration because maximum bitrate can
  reduce smoothness at 4K or high frame rates.
