v0.8.4: storage without a HEN (pre-release)

A pre-release that lets the app run on consoles where nothing opens the console's storage to it (cobanov/PS5LM#16).

Fixed

• The app no longer starts without storage on consoles where /data stays closed to homebrew titles. It asks the HEN to open /data at every start (OnionHEN does it for titles on its allowlist: add PPSA99581 to app_jailbreak.exact_title_ids in /data/OnionHEN/config.ini).
• When /data stays closed, the first start shows a screen with the firmware and two choices: get full storage (a current ShadowMountPlus, or the OnionHEN allowlist) and open the app again, or go on in the app's own space. On that route, settings, the log and downloads stay in the app's own space, and models copied over FTP to /data/homebrew/PPSA99581/models load too. USB and M.2 drives aren't reachable that way.
• Downloads into the app's own space are checked against its real free space, so a model that doesn't fit is refused before it starts.
• /data/PS5LM is created when it's missing.

Changed

• The app reserves 16 GiB of its own space on the console's SSD, used only when /data is closed to it. Consoles where /data is open keep using /data/PS5LM as before.
• The app's log now starts with the console's firmware version.

Install

Unzip ps5lm-plus-v0.8.4.zip and copy the PPSA99581 folder to /data/homebrew/ over FTP. To update, close the app and copy the new folder over the old one; don't uninstall first, since that deletes models kept in the app's own space. Check the zip against its .sha256.

If storage is still closed, please open an issue at https://github.com/abhi245y/PS5LM-Plus/issues with your app.log (/data/PS5LM/app.log, or /mnt/sandbox/PPSA99581_000/download0/PS5LM/app.log over FTP while the app runs) and your ShadowMountPlus version.

v0.8.3: PS5LM Plus

The app has a new name: PS5LM Plus.

Changed

• The app is now called PS5LM Plus, to tell it apart from Mert Cobanov's original PS5LM payload. The new name shows on the home screen, in the dashboard header and in the console's notifications.
• The title ID (PPSA99581), the data folder (/data/PS5LM) and this repository stay the same, so updating keeps your settings, models and downloads.
• The dashboard header shows the chat's address without "Chat at http://", so it never runs into the page tabs.

Install

Unzip ps5lm-app-v0.8.3.zip and copy the PPSA99581 folder to /data/homebrew/ over FTP. To update, close the app and copy the new folder over the old one. Check the zip against its .sha256.

v0.8.2

A small release so app stores can tell when PS5LM has an update.

Changed

• The app's content version now follows its release version: v0.8.2 ships as 01.008.002. It had stayed at 01.000.000 since the first release, so stores such as ProsperoStore could not see that an installed copy was out of date.
• README: new screenshots from v0.8.1 (Qwen 3.8 27B generating at 20.9 tok/s, the model library, the loaded-model panel) and a shorter text.

Install

Unzip ps5lm-app-v0.8.2.zip and copy the PPSA99581 folder to /data/homebrew/ over FTP. To update, close the app and copy the new folder over the old one; settings, models and downloads stay in /data/PS5LM. Check the zip against its .sha256.

v0.8.1

Fixed

• The chat server stopped answering after the network dropped: when the
  console's link went down, accept() failed with SCE_NET_EINACTIVEDISABLED
  (errno 163, the same 0x804101a3 a dropped download reported), cpp-httplib
  took that as fatal and closed the listening socket, and the model stayed
  loaded with nothing to reach it. llama-server now binds again once a second
  until it works (patches/0005-listener-survives-network-drops.patch).
  Checked on the console: the listener came back within a second after each
  of dozens of drops. A reply streaming at the moment of a drop is still cut.

Added

• README: the web UI with a sample chat.

v0.8.0

Added

• Downloads page (the fifth on L1/R1): a queue kept in
  /data/PS5LM/downloads.json, each entry with its speed, time left and
  state. Cross pauses or resumes (or tries a failed one again), Square twice
  cancels and deletes the partial file, or clears a finished one.
• Downloads survive a dropped connection, a pause and the app restarting: the
  file is fetched in 32 MiB pieces on two connections, the part done from its
  start is saved with the queue, and a lost connection is retried on its own
  (4, 8, 16, 32, then 60 s apart, up to 20 times in a row). The SHA-256 is
  checked once the file is whole.
• Get models: Square checks whether the file under the cursor fits, and the
  row says CHECKING while its header is read.
• A busy screen (a spinner and what is happening) while a model is switched or
  unloaded, before the restart for "unload and download", and while the
  models are planned again after a context or cache change.
• README rewritten around the app: features, the payloads it needs, controls.
  The payload's README moved to docs/PAYLOAD.md.

Fixed

• A download that lost its connection failed and threw away what it had
  (2.0 of 10.4 GB, sceHttp2ReadData 0x804101a3); now it carries on.
• A connection that went quiet could hang a download: requests now time out
  after 30 s without data and are asked again.
• Settings froze the app for seconds on every change, each one reading every
  model's header again. Only the context and cache settings re-plan now, in
  the background behind the busy screen; the others apply at once.

Measured (download speed on the console)

• The PC on the same network: 19.6 MB/s from Hugging Face on one connection.
• libSceHttp2 (HTTP/2), one connection: 2.8 to 5.9 MB/s, varying more from run
  to run than with any setting. Reads of 256 KiB gave 0.65 MB/s (each read
  waits about half a second), 4 MiB and larger 3 to 6 MB/s. Four requests on
  one template share one connection (3.5 to 6 MB/s); on four templates, made
  one at a time, 2.8 MB/s; on two, 4.2 MB/s. Made in four threads at once,
  the templates crashed the app.
• libSceHttp2 takes at most 4 requests (512 KiB pool); 8 or 16 are refused
  (0x817b121c).
• libSceHttp (HTTP/1.1): 0.44 MB/s per connection whatever the read or receive
  block size, adding up with more connections (4: 1.6, 8: 2.5 MB/s, one of
  the eight refused).
• In the app, two pieces at once on their own templates: 7.0 to 9.8 MB/s for
  a 1.9 GiB file (v0.7: 3.8 MB/s), still well under the PC's speed. Going
  further needs sockets and TLS of our own, for a later release.

Checked on the console

• A 1.9 GiB download: paused (the partial file stopped growing), resumed from
  the saved 128 MiB, closed and relaunched mid-download (carried on from
  905 MiB), finished with its SHA-256 matching.
• Get models during a download: search, listing and fit checks work.
• The busy screen on a context change; the library re-planned behind it.
• Payloads stayed up throughout.

v0.7.0

Added

• Downloads check free space first: the file and 1 GiB to spare must fit on
  the drive. When it does not, a dialog offers the drive with the most room
  for this one download; the download itself refuses too, for the
  after-restart path.
• M.2 and every mounted USB drive: Download to in Settings steps through the
  drives that are mounted (internal, /mnt/ext0, /mnt/usb0..3), the
  STORAGE tile and the usage details list each one, and the library groups
  models by drive. Models in PS5LM/models on the M.2 drive are found too.
• Before a download while a model holds the memory (under 2 GiB free), a
  dialog offers to unload it first: the app restarts without the model and
  the download starts on its own.

Fixed

• Storage figures were made up: a title's statvfs is a stub that reports
  64 GiB with 16 GiB free for every path, and statfs is not exported to
  titles. Free and total space now come from ps5-exporter (bundled since
  v0.4.0), which reads the kernel's; internal storage is /user. Without the
  exporter the space shows as unknown and does not block a download.
• Get models opened after a restart now lists the popular repositories.
• A download without a checksum survives the unload-and-download restart.

Checked on the console

• Real space: internal 166.7 of 627.6 GiB free, USB 461 of 477 GiB, as
  ps5-exporter reports them; the drive's 33 MB second partition is left out.
• A 500 GiB job refused on internal storage; a download to the USB drive;
  Download to stepping between internal and USB, saved; unload and download
  (SmolLM2 Q2_K); the scratch size warning and Clear.
• No M.2 drive is fitted, so that path is checked in the preview only.

PS5LM app v0.6.0

PS5LM app v0.6.0: Get models (search Hugging Face, see what fits, download with a checksum), file tools in the browser chat confined to a scratch folder, and image input for vision models. All checked on a PS5. Builds on Mert Cobanov's PS5LM.

Install: copy the PPSA99581 folder from the zip to /data/homebrew/PPSA99581. Sensors need elfldr running (the app loads its bundled ps5-exporter through it).

Changes

Added

• Get models page (the fourth on L1/R1): Hugging Face's GGUF repositories,
  most downloaded or by family (L2/R2), each file's size and whether it fits,
  planned from its first 16 MiB, and downloads to internal storage or USB
  (Settings), SHA-256 checked, added to the library when done. HTTPS through
  the system's own libSceHttp2 and libSceSsl. Checked on the console:
  SmolLM2-135M F16 (271 MB) at 3.4 MB/s.
• Chat tools: the browser chat's model can read, write, edit and search files
  (llama-server's built-in tools), confined to /data/PS5LM/scratch by
  patches/0003-tools-root.patch. Settings has a switch, a size warning
  (default 2 GiB) and a Clear action.
• Images: a vision model's mmproj file beside it is loaded with it
  (--mmproj), and the planner counts its memory.
• The planner can plan from the first bytes of a GGUF (a range request), the
  base of the model market's fit column.

Measured

• Writes from the app: stdio 18.5 MB/s, write() 232 MB/s on /data (USB: 293
  and 621 MB/s). Downloads use write().
• Chat tools on the console: a write to /data/homebrew lands in the scratch
  folder; relative paths start there. Gemma 4 E4B with its projector
  described a test image correctly.

PS5LM app v0.5.0

PS5LM app v0.5.0: use the model on the PS5 from coding tools. opencode, codex and Claude Code each completed a small edit against Qwen3.8-27B UD-IQ2_XXS on the console; setup in docs/CLI.md. Builds on Mert Cobanov's PS5LM.

Changes

Added

• docs/CLI.md: opencode, codex and Claude Code against the model on the
  console, each checked on a small edit with Qwen3.8-27B UD-IQ2_XXS.

Fixed

• Claude Code got HTTP 500 on every request: it sends system messages in the
  middle of a conversation and Qwen's template refuses them.
  patches/0004 folds them into the first system message.

PS5LM app v0.4.0

PS5LM app v0.4.0: a POWER card (SoC watts, energy per token, every temperature sensor) and one USAGE card for GPU and CPU, both with an expanded view on Cross. Checked on a PS5 with Qwen 3.8 27B generating: 86 to 92 W, 4.3 J per token. Builds on Mert Cobanov's PS5LM.

Install: copy the PPSA99581 folder from the zip to /data/homebrew/PPSA99581. Power and temperatures need elfldr running: the app loads its bundled ps5-exporter through it.

Changes

Added

• POWER card: the SoC's power (CPU, GPU and memory together), its history,
  energy used this session and joules per generated token; expanded, min,
  average and max, fan duty and every temperature sensor. The reading is
  sceKernelGetSocPowerConsumption's low 32 bits in milliwatts (22 W idle,
  86 W while the 27B generates), through ps5-exporter.
• USAGE card: GPU and CPU on one chart; expanded, GPU, CPU, memory, storage
  and the models on disk.

Changed

• USAGE replaces the GPU and CPU tiles; THERMALS shows the hottest sensor.

Fixed

• Speed and GPU use during a long reply: llama-server's counters move only
  when a request ends, so the live figures come from the slot's token count.

PS5LM app v0.3.0

PS5LM app v0.3.0: Settings and Logs pages on L1/R1, model details, and new THERMALS and STORAGE tiles. Checked on a PS5 (dashboard with a model generating, model details, settings saved and kept across a relaunch, logs). Builds on Mert Cobanov's PS5LM.

Install as for v0.2.0: copy the PPSA99581 folder from the zip to /data/homebrew/PPSA99581. For temperatures and fan speed, have elfldr running: the app loads its bundled ps5-exporter through it.

Changes

Added

• Pages on L1/R1: Dashboard, Settings and Logs, with tabs in the header.
• Settings page (rail and rows after the kit's Control Room design): load a
  model at launch and which one, the planner's longest context and KV cache
  type, interface sounds; saved to /data/PS5LM/settings.json.
• Logs page: app.log and llama.log, scrollable, with an errors-only filter.
• Model details on Cross over the Model tile: every llama-server argument, the
  plan, cache and preset; Triangle opens the library.
• THERMALS tile (SoC and CPU temperature, fan duty), STORAGE tile (free space
  on /data and USB), and the CPU clock. A title may not read the sensors
  (0x80020002), so the app bundles Marice's ps5-exporter (GPL-3.0, pinned
  v0.2.0) and sends it to elfldr when it is not running.
• scripts/ps5lm-app.sh press <button>: drive the screens from a PC.

Changed

• One MEMORY tile replaces MEMORY and GPU MEMORY (the GPU and CPU share one
  pool); CONTEXT takes in the session counts.
