Knutwurst 986ff00c36 Persist resume state every piece; replace conn field with a stepper
Resume: write the sidecar after every completed piece instead of batching
every 8. Each piece's bytes are already fdatasync'd and the sidecar write is
a tiny atomic tmp+rename, so an unclean kill now re-downloads only the pieces
still in flight, not a batch of up-to-8 already-finished ones. Drops the now
-unused 'unpersisted' counter.

UI: the "parallel download connections" control is now a stepper — two large
54px -/+ buttons around a tabular value, in a row beside its label, instead of
a full-width number field for a 1-16 value. Big targets and a clear green focus
ring suit controller navigation (the UI is driven by the PS5 pad via the home
tile). Tapping -/+ updates and auto-saves that field alone (debounced), applying
live on the server.

PatchDL

A standalone PlayStation 5 ELF payload that downloads and installs official game patches on your terms. It serves its own web UI and runs without etaHEN.

PatchDL is built for setups where nanoDNS blocks Sony's servers for the whole console. It resolves the Sony patch CDN on its own path, so the rest of the system stays offline and only the patches you pick get fetched.

What it does

  • Scans installed titles and classifies each one: genuine install, ShadowMountPlus mount, preinstall, or unknown.
  • Reads the title name, installed version, and the Sony version.xml URL from the PS5 app database.
  • Fetches each title's version.xml from Sony's CDN past nanoDNS (a raw DNS query to 1.1.1.1) and verifies TLS against the pinned SCEI DNAS root.
  • Picks the newest patch compatible with the current firmware (system_ver <= firmware), so an update never forces a firmware upgrade.
  • Downloads the installable package from Sony's manifest pieces and installs it through Sony's AppInstUtil service.

Safety model

Deny-by-default. A patch is installed only for a genuine install, and only when the patch metadata targets the installed game:

Source Check Download Install
official yes yes yes
shadowmount yes yes no
preinstall / unknown yes no no

Two independent guards stop the wrong target being installed: the patch target id (read from version.xml / manifest_url) must match the installed game, and the install call receives the installed game's content id from app.db. Sony may store the actual patch bytes under a regional/master title id that differs from the target; that storage id is accepted only when version.xml targets the installed title. A true target-title mismatch is refused instead of installed as a phantom title.

For PS5 titles, delta_url often points to a small *-DP.pkg helper package. That bootstrap can make the system fetch the full patch, but it follows the package's storage/master title id and can create a duplicate/ghost title for cross-region updates. PatchDL therefore prefers the Sony manifest_url, downloads every listed pieces[] entry in order, and concatenates them into one local .pkg before handing it to AppInstUtil. The delta_url title id is kept only as the storage/master-id diagnostic.

Build

Requires ps5-payload-dev/sdk. The network and install features also need the prebuilt libcurl + OpenSSL from ps5-payload-dev/pacbrew-repo placed in the SDK sysroot (target/user/homebrew); scripts/build_ps5.sh enables them automatically when present. libmicrohttpd is vendored under vendor/etahen, and SQLite is vendored under vendor/sqlite.

scripts/build_ps5.sh        # produces patchdl-ps5.elf

Deploy

This console uses the BD-JB autoloader with itsPLK's Payload Manager on port 8084 (not a 9021 elfldr). scripts/deploy_ps5.sh uploads the ELF named with its version and launches it; the payload replaces any running instance itself.

PS5_HOST=<console-ip> scripts/deploy_ps5.sh

On start it shows an on-screen notification with the URL. Open the web UI at:

http://<console-ip>:12880/

Status

0.0.3, early. Title scan, source classification, version resolution, firmware-compatibility filtering, target/storage-id handling, and the local AppInstUtil HTTP stream have been verified on firmware 11.60. PatchDL now downloads PS5 update manifests as merged piece packages under /data/patchdl; large retail updates can be tens of GB. The download queue shows live progress, and each download can be cancelled (the partial file is deleted) or a finished package deleted again, from the queue or the title card. Manifest pieces are verified in offset order and against their declared size while merging. Open items: a full large-title manifest download/install still needs an end-to-end run, the web UI marks a title "Installing…" but reads progress from the PS5's own notifications rather than a percentage, and disc-based games need the disc inserted for their patch to apply (a normal Sony requirement). Settings (global policy and the per-game toggle) persist to /data/patchdl/config.json and survive a restart.
