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.

The relinker reads a plain ELF executable and skips SELF containers with a
warning, so an eboot.bin or a *.prx taken from a title cannot be relinked
before it is unwrapped, and the repository has no tool for that.
The inner ELF program headers of a container carry stale offsets: a SELF
inserts its own metadata blocks between the segments, so the data sits at the
offsets of the SELF segment-record table at file offset 0x40. The segments are
also packed without honouring p_align, while ELF requires p_offset % p_align
== p_vaddr % p_align, which the relinker enforces on guest modules. The tool
places the segments from the records, falls back to the vaddr to file mapping
of the containing PT_LOAD for segments the table does not cover, copies every
region to an offset satisfying the alignment, and refuses a container whose
load segments all look encrypted.
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.

Four catalog titles (ProsperoTV PPSA99003, ProsperoRadio PPSA99001,
ProsperoLight PPSA99002, ProsperoLichess PPSA99009) locate their own
directory with stat("/app0/eboot.bin"), which always exists on the
console, and fall back to /data/homebrew/<title id> without it; that
directory is empty here, so they fail to load their fonts and die with
"renderer init failed". Staging the original eboot.bin next to the app
resources makes all four load their fonts; ProsperoLichess then renders
(1267 frames in 60 s on Windows).

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.
