A Vulkan surface can offer HDR10 formats while the display is not in
HDR (KDE Wayland with RADV lists them with the output's HDR disabled),
so on hosts other than Windows the probe now reports an SDR monitor and
HDR output stays off until an output-state signal exists. A probe test
checks that a window without a Windows monitor report reads as SDR with
an HDR10 surface.
The HDR10 present test now also changes the monitor's luminance while
presenting HDR10, and the presenter logs the HDR metadata it sets.
AI-assisted: yes
Detect HDR output on the host: on Windows the monitor showing the window
must run in HDR10 (DXGI IDXGIOutput6), and on every host the window's
Vulkan surface must offer a 10-bit VK_COLOR_SPACE_HDR10_ST2084_EXT
swapchain with VK_EXT_swapchain_colorspace and VK_EXT_hdr_metadata. The
monitor's luminance comes from DXGI; hosts that report none get 1000
nits peak and full frame, 0 nits black.
While HDR output is available, sceVideoOutGetOutputStatus reports
dynamic range 2 and flag bit 0, sceSystemServiceGetHdrToneMapLuminance
reports the monitor's luminance, and every open port's output mode
event fires when that changes. PQ display buffers are presented
unchanged through an HDR10 swapchain with HDR metadata; any other
display buffer switches back to the SDR swapchain. Without HDR output
the PQ to SDR conversion uses the peak the title was last told as its
white level.

A direct memory page mapped at one guest address now lives in private
MEM_WRITE_WATCH memory at that address, and its writes are collected with
GetWriteWatch like flexible memory: no fault is raised. A page mapped at a
second address moves its whole resident run into the section, behind a
read-only fence while it is copied, and every address becomes a view of it,
tracked by write protection. Unmapped resident pages that are not blank are
kept in a private reservation until they are mapped again, not in the
section.
Ported onto main's 4 KiB subpage tracking of shared views: resident runs
keep a per-page collected bit and enter the fresh ranges, so Fresh and
Armed collections select them like shared views; a demoted run carries its
collected bits into the views and reports every page once. MapAlias throws
through refuse() when a resident run extends outside the aliased range, and
the caller keeps main's fallback.

With --trace-imports the entry stub resolves TraceImport_nid_no_patch
in libc.prx and passes each function import through it before writing
the slot: every PLT slot, and a GOT slot only when the original symbol
is a function, so data imports such as __stdoutp keep their address.
Without the option the output is unchanged.

The console's mouse reports relative motion, so the host cursor can never line
up with the cursor a title draws. While a title has a mouse open and the
window is focused the host cursor is hidden and captured, released on focus
loss or while the pad's mouse-to-stick toggle is on. Motion deltas are scaled
from the presented image's size in window units to the title's display
resolution with sub-pixel carry, so the title's cursor travels as far as the
host pointer would, on scaled desktops and letterboxed windows alike.

The relinker's repeatable --executable converts another executable of the
title beside the output, sharing its libs, app0 and guest modules.
sceSystemServiceLoadExec maps /app0 paths to those executables, passes the
argument list on the new command line and finds the main executable through
APS5_EBOOT. RetroArch (PPSA99169) starts its frontend picker this way.

A --windows-gui build started from Explorer, or any Windows executable
started without a standard output or error handle, lost everything it
printed: the entry stub's messages, the libraries' stdout and stderr,
uncaught exception messages and crash reports.
Before it enters its directory or loads a library, the entry stub now
checks the standard output and error handles, and gives each missing one
anyps5.log beside the executable. The C runtime of the libraries it then
loads adopts the file. Executables started with handles are unchanged,
and one that cannot create the file starts as before.

Document --help output and status, distinguish no-argument errors, and include help in the successful exit code description.
AI-assisted: yes (OpenAI Codex).
anyps5-input.ini accepts LeftStickDeadzone and RightStickDeadzone (whole
percent, 0 to 90), a radial deadzone on the controller sticks whose
remaining travel is rescaled to the full range, and MouseSensitivity
(above 0, at most 10), which replaces the fixed factor of 1 for mouse
look. The defaults keep the current mapping exactly.
Add an optional input helper for test runs without desktop input injection. Preserve physical input and release injected buttons automatically.
Validation: guest_pad tests and Python helper CLI smoke checks passed. Written with AI assistance.
