Follow-up to the previous commit, from Nemoumbra's questions - which found a worse
spin than the one that fix addressed.
InputSink couldn't tell "nothing right now" from "peer is gone": Fill() treats
recv() == 0 as no data and only sets hasError_ on a real error. Block() then waits
with WaitUntilReady(), which reports a closed socket as ready immediately and
forever, so TakeExact() looped on it without ever returning. A client that
disconnects with half a frame buffered - easy to do while blasting messages - put
the server in an infinite loop inside TakeExact, never even returning to Process().
Measured 7.95 CPU-seconds over 8 seconds; 0.08 after.
So: track EOF explicitly (sticky atEnd_, exposed as AtEnd()), and have Block() give
up when nothing more can arrive.
That information was being thrown away in three more places:
* Process() only tried to fill when the sink was already empty, so a disconnect went
unnoticed for as long as there were leftovers - and if those leftovers were a
partial frame, the read above never completed. Always fill, and close once the
peer is gone and we've consumed what it sent.
* ReadPending() uses TakeAtMost(), which returns 0 both for "nothing right now" and
"nothing ever again", and then reported success having consumed nothing. Ask the
sink which it was.
* Both TakeExact() call sites answered a failed read with POLICY_VIOLATION, blaming
the client for a protocol error when it had simply disconnected. Check the sink
and report ABNORMAL when that's what happened.
Also stop queueing data once our own close frame is queued. RFC 6455 5.5.1 forbids
data frames after a close, and beyond the protocol, anything appended afterwards
keeps the buffers non-empty and starves the "everything is flushed" check that ends
the connection. Observed the server pumping 167MB of log broadcasts after being
asked to close.
The repeated close-and-discard is now one helper.

Reported by Nemoumbra: the debugger server could get stuck in a tight select()
loop after a lot of traffic, burning a core.
Once OutputSink hits a real send() error it latches hasError_, after which Flush()
returns immediately without consuming anything, so out_->Empty() is false forever.
Process() waited for that to empty before finishing the close, kept the fd in the
write set, and select() reports an errored socket as ready every time - so it
returned true on every lap without ever making progress, and WebSocketDebuggerLoop
span. This needs sentClose_ to be set for it to be unrecoverable, since otherwise
the read side notices the disconnect and closes; a client that sends CLOSE (or
trips a protocol error) while output is backed up gets exactly that. Reproduced
with a client that queues ~120MB of responses, sends CLOSE, then resets the
connection without reading: 6.02 CPU-seconds over 6 seconds before, 0.06 after.
Treat an output error as fatal to the connection instead.
Also, select() returning -1 always returned true, so any error that doesn't fix
itself (a bad fd rather than EINTR) was a second busy-loop with no wait at all.
EINTR retries, everything else closes.
Finally, SendFlush() erased the drained bytes off the front of outBuf_ every lap.
With a backlog that's a memmove of the whole buffer per lap, i.e. quadratic in the
backlog, which burns CPU on its own while draining a slow client. Track a consumed
offset and only compact once the dead prefix is worth reclaiming.

VulkanGraphicsContext::InitSurface() threw away VulkanContext::InitSurface()'s
VkResult and carried on, so a failed surface init surfaced as
_dbg_assert_(GetAvailablePresentModes().size() > 0) in the VKContext
constructor rather than as a graphics error with the usual backend fallback.
The vkCreate*SurfaceKHR failure path in ReinitSurface() didn't log anything
either, so the assert was the only trace of it.
Now ReinitSurface() logs and sets init_error_ for all three ways it can bail
(surface creation, ChooseQueue, present mode enumeration), InitSurface()
checks the result, and MainThreadFunc() passes the message back out instead of
writing it to a local it then drops - Windows/main.cpp was reporting
"Failed to initialize main thread function." to the user.
Also deletes the Application on that failure path, which was leaked.
The two long-standing bug reports had a shared root: the service loop could
end up in a state it never left.
- Exit hang: UPNP_CMD_EXIT was queued alongside port requests and only acted
on when it reached the front. A request that couldn't complete was never
popped, so exit sat behind it forever and join() blocked indefinitely.
Exit is a flag now, checked before anything else.
- CPU spin: wait_for() with a predicate returns immediately when the predicate
already holds, so a stuck queue head meant a tight loop. sceNetInet's bind()
queues UPnP_Add regardless of the setting, so this hit whenever UPnP was off
and a game used sockets. The loop always blocks now, and requests are dropped
while UPnP is off.
- Failed discovery was retried every 5s forever, each time a full 2s SSDP round
plus an error toast. Now backs off 5s -> 300s and reports once.
Other things found while in here:
- Every failed Initialize() leaked a UPNPUrls + IGDdatas, so ~every 5 seconds
for anyone with UPnP on and no router. The manual miniwget/parserootdesc/
GetUPNPUrls block was also redundant - UPNP_GetValidIGD does all of it and
memsets over the result, leaking the URLs and costing an extra HTTP round
trip per attempt.
- UPNP_GetValidIGD's status was never checked, so we could go DONE with no
usable IGD and hand a NULL controlURL to UPNP_GetConnectionTypeInfo.
- miniupnpc's strncpy into the port-mapping-entry buffers doesn't guarantee a
terminator; an 80-char description ran std::string off the end of desc[80].
- Add() marked another app's port "taken" only after our own add succeeded, so
a failed add left their mapping deleted and never restored.
- Clear() walked the router's entire table at exit, one HTTP round trip per
index. It now deletes only what we know we mapped, and the exit cleanup has
a time budget so an unreachable router can't stall shutdown.
- The in-flight request stayed in the queue during the router call, so a
same-port request arriving concurrently could erase it and be dropped
unexecuted.
- The queue is bounded, and last-write-wins per port collapses the churn from
games that rebind in a loop.
- The mapping description is built when the request is queued rather than read
off g_paramSFO from the UPnP thread later.
The thread now only exists while the setting is on - turning it off makes it
remove its mappings and exit, turning it on starts one. That means __UPnPInit()
has to run after the config is actually loaded; g_Config.Init() only builds a
lookup table. QueueRequest() reconciles too, so a per-game config or a libretro
core option enabling UPnP works without a notify at every call site.
The settings checkbox is disabled in-game, since sceNet latches related
settings at boot and a game that already mapped its ports wouldn't cope with
them disappearing.

The mangling encodes the source signature, so a demangler correctly prints
"Son::~Son()" - but the emitted function takes a second argument (a short in
a1) and returns "this". Anything deriving a function signature from the name
gets it wrong. Verified against both binaries: the flag is only tested for
being positive, which is what selects the operator delete call, and callers
pass -1 far more often than anything else.

The file holds the Hebrew strings in visual order, for renderers with no bidi
of their own, but only 101 of its 269 Hebrew entries were actually a reversal
of he_IL. The rest were left unreversed, reversed by word instead of by
character, or garbled outright ("Win" read as gibberish either way round).
Derived them all mechanically instead. The transform reproduces the entries
that were already right, and keeps as single units the things that must not be
spelled backwards: the \n escape, %N placeholders, runs of Latin and digits,
and an & accelerator together with the character it marks.
The [Dialog] save/OSK strings are the exception - he_IL already stores those
reversed, since PPGeDraw draws them and has no bidi, so the invert file just
mirrors he_IL for those 22 keys.

The old one was reverse engineered from a handful of symbols and got the
shape of the format wrong - it required a digit right after the kind
character, which most real symbols don't have. Measured against a PSP
executable that shipped with its symbol table intact, it decoded 238 of
4662 mangled symbols, most of those incorrectly.
Worked out properly from that binary, the format turns out to be:
__0 <kind> <name...> <params> [_ <return type>] [<qualifier>]
where the kind character (member function, free function, operator, data)
is the only thing that says how many name components follow, since nothing
separates the last one from the first parameter. Lengths are letters
(A = 0, a = 26); "5" marks an enclosing namespace; "7...._" is a template
argument list, with "4" plus a compact integer for a non-type argument and
"9<index>A" for a back-reference to one; "T<index>" and "N<count><index>"
repeat an earlier parameter; a trailing "K" is const and a trailing "T" is
a static member function. Also handles __TID_/__T_ (the two halves of a
class's RTTI) and __sti__ (a translation unit's static initializers).
That decodes 4661 of the 4662. The one holdout is an STL symbol whose
template argument is a reference to a member of another template.
Declarator wrapping is shared with the CodeWarrior demangler now, so
pointers to arrays come out as "short (**)[64]" in both.

rather than attested.

div.s now maintains fcr31's Cause.Z and (when the trap is masked) sticky
Flag.Z bits, in the standard MIPS bit positions. Only a finite non-zero
dividend counts, so 0/0, inf/0 and NaN operands are excluded per IEEE 754.
When the guest has the trap unmasked, the new Core_FPUException() reports it
with the usual module suffix and MIPS call stack, and fd is left unwritten as
hardware would. That's gated behind a new developer setting, off by default:
PSP threads start with fcr31 = 0x00000e00, i.e. three of the traps already
enabled, and games divide by zero without meaning anything by it. The fcr31
bits are updated either way, so what the game reads back doesn't depend on
the setting.
Interpreter only - the JITs are unchanged, and none of this is reachable
under them.

Checked against two PSP binaries that shipped with intact symbol tables,
which turned up several constructs the format's usual description doesn't
mention:
- Template arguments are written literally inside the length-prefixed name
("39CList<Q38hlScreen5Brwsr13CContentsUnit>"), not with a "__PT" prefix,
and they nest. Function templates put theirs in the base name instead,
followed by the return type.
- A family of "@"-decorated symbols for things with no C++ name: thunks
("@12@__dt__3SonFv"), string literals, function-local statics and their
guard variables. Plus __vt__/__RTTI__/__sinit_, printed in the same style
as the Itanium special names.
- Types are now built as a split declarator, so a pointer to a function
comes out as "int (*)(int)" rather than "int (int) *".
Also stop the lenient pass from turning plain C names with a "__" in them
into nonsense - "I3dClut__FlushCache" became "I3dClut(long, ...)". It now
requires a class qualifier, which costs nothing: over ~10000 symbols the
lenient pass rescued none and only produced those false positives.
Symbol map names go from 128 to 256 characters, since a demangled name
keeps its parameters and templates make short work of 128.
docs/CodeWarriorMangling.md describes the format, marking the parts that
are inferred from cfront rather than attested in a real binary.

Older PSP binaries weren't built with GCC, so the Itanium demangler doesn't
help with them. Add two more, tried in turn by DemangleSymbolName():
- Metrowerks CodeWarrior, a descendant of the AT&T cfront scheme
("getDistance__6KzUtilFP7st_unitP7st_unit"). Handles Q<n> qualified names,
the cfront type codes including T/N back-references, cv-qualifiers, and the
operator/ctor/dtor name codes.
- SN Systems SNC/ProDG ("__0f5DstdIbad_castEwhatvK"), which encodes name
component lengths as letters. Reverse engineered from a small sample, so
the parts that are guesses are marked as such - they don't affect the name.
Both are rougher than the Itanium one: they aim for a correctly qualified name
plus a plausible parameter list, and print "..." for a parameter they can't
decode rather than throwing the name away. Results come back as a
DemangledSymbol with the name, parameters, return type and qualifiers kept
separate, in case a caller wants more than the printed string.

GLRenderManager is documented as "emu thread records, render thread executes",
but GL has to record device object creation as init steps rather than just doing
it, and InitGPU() runs on the ExecLoader thread - GPU_GLES's constructor builds
DrawEngineGLES, whose InitDeviceObjects() reaches initSteps_ through
CreatePushBuffer and CreateInputLayout. The emu thread is still drawing the
loading screen into the same FastVec until the loader thread is joined, so two
concurrent push_uninitialized() can both reallocate, and one writes its step into
a freed buffer - losing a shader or buffer creation, or scribbling an owned
pointer into freed memory.
frameData_[].activePushBuffers is genuinely three-threaded too: inserted into by
whoever creates a push buffer, erased on the render thread via GLDeleter, and
walked on the render thread each frame.
A mutex each, uncontended in practice. Note this makes the existing access safe
rather than fixing the layering - Vulkan avoids the problem by creating objects
directly and deferring the rest to FinishInitOnMainThread, which GPU_GLES has
never had. Moving GL's device object creation there would be the better fix.

The loop queue-deleted the VkPipeline and nulled the slot without deleting the
Promise the array owns - DestroyVariantsInstant right below it shows the intended
ownership. That's one leaked Promise per destroyed variant per cached pipeline,
on every MSAA or resolution change.
It also wrote pipeline[] without taking mutex_, which the header documents as
protecting that array and which the render thread holds while reading and
replacing the same slots in PerformRenderPass. The two have to be fixed together:
the missing delete was the only thing keeping this a leak rather than a
use-after-free.

GetRenderPass() looks up and inserts into renderPasses_ from the main thread
(EndCurRenderStep, CreateGraphicsPipeline) and from the render thread
(PerformBindFramebufferAsRenderTarget), unsynchronized. The render thread really
does insert rather than only hit: PreprocessSteps rewrites the load actions to
CLEAR when it merges a clear-only pass into a later one, after the main thread
already looked up the pre-merge key. DenseHashMap::Insert can Grow(), which
reallocates the buckets out from under a concurrent Get().
VKRRenderPass::Get() has the same problem one level down - it creates the passes
lazily and is called from both threads on the same object, so two threads hitting
an empty slot each create a pass and one gets overwritten and leaked, while the
sample-count branch can queue a pass for deletion that the other thread is about
to hand to vkCreateGraphicsPipelines.
A mutex each. Handing the VKRRenderPass pointer out from under the map lock is
fine, entries are only ever erased all at once in DestroyDeviceObjects.

Core_ProcessStepping() returns immediately when the CPU is stopped with nothing
queued, so Core_RunLoopUntil() returns immediately, so whatever drives it comes
straight back. headless does that in a loop with no frame pacing at all, so a
paused emulator sat at 100% of a core: measured 6.02 CPU-seconds over 6 wall
seconds parked at startBreak. A debugger session is stopped most of the time, so
this also dominated any profile taken of one - showing up as synchronization
overhead around Core_RunOnCPUThread, which was just the hottest thing inside the
spin rather than a problem with the queue.
The CPU thread now blocks on a condition variable in that case. Anything that
gives it something to do wakes it - Core_RunOnCPUThread() on push (with the
queue mutex held, so it can't sleep on a task already queued),
Core_RequestCPUStep(), and Core_Resume() - so the 2ms timeout is only a backstop
for state changed without a wake, never how work is normally noticed.
The wait is deliberately short rather than indefinite: callers do real work after
Core_RunLoopUntil() returns, and in the app build that includes rendering the
ImGui debugger from this same thread, so this has to bound how long a paused
frame takes rather than replace the frame loop.
Now 0.05 CPU-seconds over the same 6 seconds. No measurable cost to anything
else: an identical scripted boot runs in 2514ms vs 2476ms before, and 20
consecutive cpu.stepInto still complete promptly. 55 unit tests pass, 314/314
pspautotests with --graphics=software.
Also: wsdbg's README claimed a raw JSON line gets a ticket auto-assigned when it
lacks one. It doesn't - the code deliberately sends raw lines exactly as written,
and omitting the ticket is how you say "not waiting for an answer". Corrected.

GameInfoTex::Clear() only reset dataLoaded when there was data to clear, but
several paths deliberately set it on a file that turned out not to exist (the
ARCHIVE_ZIP case, the "no icon" fallback). Those kept dataLoaded across a
Clear(), so FinishPendingTextureLoads stamped timeLoaded again and the tex read
as permanently Failed().
PurgeType slept 10ms even when it had nothing to retry.
Fix three comments that no longer described the code: Clear() doesn't start a
thread, Priority() no longer calls GetFileLoader(), and the work item's
destructor doesn't touch the flags - Run() has to mark them itself, which is
worth stating since missing it strands them in pendingFlags for good.

The work item wrote title, id, id_version, region, errorString, hasConfig and
gameSizeUncompressed with no lock held, while the main thread reads them under
info->lock. title is the sharp one - an unsynchronized std::string write against
a locked read in GetTitle()/GetDBTitle() is a real data race, not just a stale
read. SetTitle() already existed and was used in exactly one of the six places.
The two expensive calls (HasGameConfig, which hits the file system, and
GetSizeUncompressedInBytes) stay outside the lock - the main thread takes it
every frame, so blocking on I/O under it would show up as UI stutter.
PurgeType read hasFlags/fileType/pendingFlags under mapLock_ only, racing the
worker's MarkReadyNoLock. It also erased entries without dropping their
textures, unlike Clear() - so a work item that finished just before PurgeType
took the lock could be left holding the last reference, and ~GameInfo would
then release GPU textures on a worker thread.

GetInfo() masked out any flag that a *pending* work item was already going to
fetch, FILE_TYPE included. But every work item starts by switching on
info->fileType, so "another item will compute it" isn't good enough - if that
item hadn't reached Identify_File yet, the second one fell through to default:,
marked its flags ready and loaded nothing. The data then looked present forever,
so e.g. a PIC1 requested while an ICON load was in flight could just never show
up. Easy to hit since the screens request different flag combinations for the
same path, and BackgroundAudio calls GetInfo from the audio thread.
Always redo the identification unless FILE_TYPE is already in hasFlags (i.e.
final), and have Run() switch on a local copy so a concurrent item can't shift
it underneath us mid-switch.

- The SND branch for PSP_DISC_DIRECTORY set pic1.dataLoaded instead of
sndDataLoaded, copy-pasted from the PIC1 branch above it. Asking for SND
without PIC1 left pic1 marked as loaded with no data, so SetupTexture
stamped timeLoaded and pic1.Failed() stayed true for good.
- The SIZE branch wrote two locals that were only ever 0 into saveDataSize
and installDataSize, wiping what a previous SAVEDATA_SIZE fetch computed
while hasFlags still claimed it was valid.
- GetDBTitle() returned the filename when a title existed but PARAM_SFO
didn't, and an empty string in the opposite case - the condition was
inverted. Look up the DB when we have an id_version, then fall back the
same way GetTitle() does.

This is a leftover from the old "native" library. Its only users are the Win32 GE
debugger's preview windows, which call glsl_create_source/destroy/bind/unbind and
read four locations off the struct.
Everything else was dead: glsl_create was declared but never defined anywhere,
which made the entire file-loading and auto-reload half of glsl_recompile
unreachable (glsl_create_source always passes empty filenames), along with the
mtime fields, AutoCharArrayBuf and the VFS/stat includes. glsl_attrib_loc,
glsl_uniform_loc and glsl_get_program had no callers, and the active_programs set
was written and never read. The unused convenience locations cost a
glGetUniformLocation round trip each at link time.
The bug: the vertex shader was leaked when its own compile failed - the fragment
path right below it already deleted it correctly. Failed links leaked the program
object too.

The Intel workaround sscanf'd "Build %d.%d.%d.%d" against glGetString(GL_VERSION),
which reads like "4.5.0 - Build 26.20.100.7870" - sscanf literals have to match
from the start, so it never returned 4 and HasIntelDualSrcBug was never consulted.
It's been inert since it was written, and the drivers it targeted are long gone.
Removing it orphaned the two helpers, so those go too.
Separately, when gl3stubInit() fails we left ver[0] at 3 while clearing GLES3.
Extension enumeration keys off the version, not the flag, so it went on to call
glGetStringi - one of the very entry points whose absence makes gl3stubInit()
fail. Drop back to 2.0 on that path, like the branch above it already does, and
null-check what glGetStringi hands back.

* TransitionDepthStencilImageAuto set dstAccessMask to TRANSFER_READ_BIT for
TRANSFER_DST_OPTIMAL. The color path and this function's own source-side switch
both use TRANSFER_WRITE_BIT - it's a copy-paste from the TRANSFER_SRC case two
lines up. Every depth copy and blit went through it.
* VulkanMayBeAvailable's per-device loop did anyGood = !blacklisted, overwriting
the verdict from earlier devices, so a blacklisted GPU enumerated after a good
one hid the Vulkan backend entirely. Hybrid-GPU machines are exactly what the
blacklist targets.
* The instance extension scan stopped as soon as it found the platform surface
extension, so a driver reporting that before VK_KHR_surface made us give up
with "Platform surface extension not found". Enumeration order isn't specified.
* CreateDevice only logged when vkCreateDevice failed, then carried on to report
success, call VulkanSetAvailable(true) and build a VMA allocator on a null
device behind an assert that's live in release builds.

The previous commit moved everything out of the list before running callbacks, to
avoid appending to a vector being iterated. That regressed device teardown: a
callback can queue more deletes (~VKFramebuffer does, via ~VKRFramebuffer, which
queues image views, image allocations and framebuffers), and those land back on a
list that used to be picked up by the object loops later in the same pass.
That's harmless for the per-frame lists, since callbacks queue onto the global
list and a later frame drains it. But PerformPendingDeletes() drains the global
list itself, and DestroyDevice() calls it immediately before vmaDestroyAllocator
and vkDestroyDevice - so the re-queued objects were never destroyed at all.
Loop instead. In the per-frame case that's one extra empty lap.

pipelineLayouts_ was mutated from the main thread (CreatePipelineLayout, and the
deferred callback queued by DestroyPipelineLayout) while the render thread walked
it every frame in FlushDescriptors. Exiting a game in Vulkan mode hits this
reliably: ~GPU_Vulkan stops the render thread and destroys the draw engine's
layout, but the destruction is deferred onto the delete list and doesn't actually
run until a BeginFrame two frames later, with the render thread running again.
Guard the list, and the lifetime of the layouts in it, with a mutex.
The global delete list had the same problem - VulkanDescSetPool::Recreate queues
the old pool from FlushDescSets on the render thread, which happens for real once
a game goes past the initial 1024 descriptors, while the main thread moves the
list into the current frame's list in EndFrame(). Lock the queueing functions and
Take's source list.
While in there:
* Take() didn't move queryPools_, so query pools queued for deletion sat on the
global list until device teardown instead of being deleted a few frames later.
* PerformDeletes now drains into a local list before destroying anything. A
callback is allowed to queue further deletes (~VKFramebuffer's does, via
~VKRFramebuffer), which used to append to the very vector being iterated.
They now get the normal deferral instead of running in the same pass.
* Missing semicolon in BeginFrame that only compiles because VLOG is empty.

Unlike the directional moves, this doesn't look at where anything ended up on
screen - it walks the hierarchy in the order views were added, flattening nested
groups in place. That's what makes it predictable in the layouts where "what's
to the right of this" has no good answer.
A view is a stop if it's focusable and enabled, the same test the directional
moves apply, so the two agree on what's reachable. Hidden subtrees are skipped
whole, which is what keeps a TabHolder's inactive tabs - V_GONE rather than
removed - out of the order without any special casing. Containers are gated on
visibility only, not enabled, matching Key/Touch/Axis: disabling a container
doesn't stop its children being interactive anywhere else either.
Ctrl+Tab stays with ChoiceStrip, which uses it to switch tabs.
focusMoves now holds FocusMove rather than raw keycodes, so the direction is
decided in one place while the modifiers are still around, and a held key
repeats in the direction it was originally pressed with - the synthesized repeat
has no modifiers of its own. That also retires the keycode switch in
UpdateViewHierarchy and IsScrollKey, which had no other callers.

NativeKey builds a copy of the key with the Ctrl/Shift/Alt/Meta flags attached,
but has been queueing the original ever since a47edbf6ef moved the dispatch from
a direct g_screenManager->key(modKey) call to the event queue - so modKey has
just been dead since then, and nothing downstream ever sees a modifier.

These two raised the memory exception and then went ahead and did the access
anyway, unlike every other load/store here. A quadword access that isn't
16-byte aligned isn't valid, so there's nothing to carry out - and on 64-bit,
where GetPointerUnchecked is base + address with no masking, an address that
failed the validity check meant dereferencing whatever that landed on.

vrot clears the D prefix for the cosine lane, since the prefix doesn't apply
there, but shifted the saturation mask by cosineLane rather than cosineLane * 2.
That field is two bits per element - ApplyPrefixD reads it as (data >> (i * 2))
& 3, and every other site in the file shifts accordingly - so for lanes 1 and up
it cleared the wrong lane's saturation and left the cosine lane's in place. The
mask field next to it is one bit per element and was already right.
Only reachable through the interpreter, but that includes the JITs, which fall
back here for any prefixed vrot.

ins derived its width as (_SIZE + 1) - pos, which is zero or negative when the
encoded msb is below pos: the following shift is then 32 or more, undefined, and
on x86 produces an all-ones mask that writes bits the JITs don't touch. Build
the mask from msb and shift it down instead, which is what the JITs do and can't
shift out of range. Hardware calls that encoding unpredictable, so consistency
is all that's wanted here.

The alignment checks added in d8edeb7649 return out of the instruction handler
without advancing PC, so with IgnoreBadMemAccess - which is the default, and
which makes Core_MemoryException log and return - the run loop comes straight
back to the same instruction and never gets past it. cpu/crash/crash_read_u32
under -i logged the same SIGSEGV 585096 times in 30 seconds before being killed;
the JIT runs it to completion.
Continue instead, the way Memory::Read_U32 did before those checks existed and
the way the JIT's safe-memory path still does: loads produce zero, stores are
dropped, PC advances. When the exception is set to break rather than ignore,
Core_Break has already stopped the core by the time we get here, so nothing
changes for that case.
lv.q/sv.q are left alone - they already fall through and do the access.

Every JIT backend puts the host FPU into the mode fcr31 asks for (bits 0-1 and
24) before running emulated code, and takes it back out before calling any host
code. The plain interpreter did none of that, so all its float math rounded to
nearest with denormals intact no matter what the game had set - cpu/fpu/fpu
fails under -i and passes under the JIT on exactly this.
Move the helpers the IR interpreter already had for this out of IRInterpreter
and into MIPS.cpp as ApplyHostRoundingMode/RestoreHostRoundingMode, and use them
around the interpreter's run loop and single step, restoring around syscalls and
replacement functions, which are host code. ctc1 re-applies immediately, since
the interpreter has no block boundary to defer it to.
round.w.s changes with it: it was floorf(x + 0.5f), which is half-away-from-zero
rather than the half-to-even every JIT produces, and the add would now pick up
the guest's rounding mode on top of that. round_ieee_754 is both correct and
mode-independent, and is what cvt.w.s already used for the same rounding.

The disasm window cached the flattened symbol list and only rebuilt it when one
of three menu items said so. Nothing marked it dirty when a game booted or
exited, and a new SymbolMap is allocated per boot, so the list kept showing the
previous game's functions.
Give SymbolMap a version counter that every mutator bumps, and let the window
compare against it instead. The counter is process-wide rather than per-map, so
a fresh map can't hand out a version a cached copy already holds.
Also re-find the selected symbol by address after a rebuild (the index means
something else afterwards), and drop the unused symbol cache members in
ImMemWindow.

C++ homebrew has an unreadable symbol table -
everything is _ZN10PxRenderer7DrawImmE... - which makes the disassembly and
symbol list nearly useless. Add an Itanium C++ ABI demangler and run ELF
symbols through it on load, in both ElfReader::LoadSymbols (unstripped EXECs,
which is what a CMake pspdev EBOOT actually contains) and the companion-ELF
path.
The demangling standard is called Itanium for historical reasons - it
was defined for Itanium but ended up being almost universally
applicable.
Written from scratch rather than using __cxa_demangle, which doesn't exist on
MSVC/UWP, or vendoring LLVM's demangler, whose license doesn't fit. Anything
unrecognized (arbitrary constant expressions, decltype) aborts the parse and
the caller gets the original mangled name back, so a caller never sees a
half-parsed result. Recursion is depth-capped since the input comes from a
file we didn't write.
Checked against c++filt as an oracle: of 1089 mangled symbols in a real C++
homebrew EBOOT, one differs; of 55189 from libstdc++/libLLVM/cc1plus, 22
differ and 413 are declined. Fuzzed with 220k mutated and random inputs under
ASan/UBSan.
Also adds a right-click menu to the ImDebugger symbol list.
Note that SymbolMap stores names in char[128], so the longest STL names get
truncated in the UI. Still far more readable than the mangled form.

When launching a file from outside the main screen (file association, shortcut,
drag-and-drop), the info hasn't been computed yet, so the file type and ID checks
that decide what to do with the file were reading empty data. Add

it there.

Opening an official updater (a PSP/GAME/UPDATE EBOOT.PBP, identified by the
MSTKUPDATE disc ID) from the main screen now brings up a confirmation dialog
that unpacks the firmware into the NAND directory, where the emulated
flash0/flash1 live. Running the updater itself doesn't work, so there was
nothing useful to do with one before.
Unpacks the file list for the model we claim to be (iPSPModel), on a worker

sceIoDevctl 0x01E18030 asks whether the disc's region matches the console's.
Unusually it answers through the return value rather than an output buffer -
1 matches, 0 doesn't - so leaving it unimplemented read as a mismatch, and the
VSH opened on "This disc cannot be started. The region code is not correct.",
asking 12 times. PPSSPP has no region-locked discs; anything it can load is
something it should run, so this always matches. The call now happens once.
Behind it is a second thing, not fixed here: the VSH believes a disc is inserted
at all because nothing in PPSSPP models an empty drive. sceUmd reports
PSP_UMD_PRESENT | PSP_UMD_READY unconditionally, and devctl 0x01F20001 always
answers "game disc". JPCSP answers "no disc" when no ISO is loaded, which is why
it never reaches the region question. Giving those two a notion of "no disc"
would be the real fix - low risk for games, which always have one, but it is on a
path every game uses, so it is written up in docs/VSHBootInvestigation.md rather
than done as a drive-by.
With this the shell reaches the interactive XMB: the error is dismissable with
circle and the menu behind it works. The per-frame display list stops settling
into one repeated frame and alternates between 45 and 48 stall points, which is
the headless-visible sign of a live menu rather than a static dialog.

pspDecryptPRX() tried types 0, 1, 2, 5 and 6. flash0:/vsh/etc/index_XXg.dat -
the index of what the XMB shows, fetched through sceResmgr_9DC14891 - needs
type 9, so it failed and the shell had no menu to build.
Type 9 is type 6 with three differences, all following from a type 9 file
carrying a real ECDSA signature at 0x104..0x12C where a type 6 file has nothing:
- The "must be empty" header check stops at 0x104 instead of 0x10C. The index's
signature starts there, so 8 of its bytes were failing type 6's check - the
original failure.
- The signature is left out of the hashed header rather than fed into it. JPCSP
zeroes buf2[0x34..0x5C), which is that same range once its header
rearrangement is undone, so PRXType9 just leaves the field zero.
- ecdsa_hash in the KIRK CMD1 header stays 0. Type 6/7 set it, but the branch
type 9 takes writes only the mode word, and setting it made KIRK reject the
block.
Tried last in the chain: its header check is a subset of type 6's, so a genuine
type 6 PRX would pass it and then fail on the hash, and trying it earlier would
shadow the real answer. False positives are not really possible either way - the
SHA1 check inside has to match before anything is decrypted.
Verified end to end: 496 bytes in, 159 out (the comp_size in the header),
starting "release:". sceResmgr checks that prefix and says so in its log line,
since a wrong-but-plausible decrypt would otherwise look like success here and
fail much later as an unreadable index.
The VSH now draws something different - the per-frame display list settles at 24
stall points rather than 38 - but what it shows is not visually confirmed;
framebuffer readback doesn't work under headless on either backend.

Found the cause of the red error screen the VSH ends on. Every resource load in
the boot succeeds - fonts, all the plugin RCOs, topmenu_icon.rco - and then:
sceIoOpen(flash0:/vsh/etc/index_02g.dat) -> fd 8
sceIoRead(8, 092a2d40, 496)
sceIoClose(8)
unresolved import sceResmgr/9dc14891, called from 'vsh_module'
sceKernelExitDeleteThread(1)
index_02g.dat is the index of what the XMB displays, and it is encrypted (it
starts "PSPsysGP"). sceResmgr_9DC14891 decrypts it. There was no sceResmgr module
at all, so the call trapped, the index stayed encrypted, and the ScePafJob thread
building the top menu exited - a shell with everything loaded and nothing to show.
This adds the module and the three tags it needs (0x0B2B90F0/91F0/92F0, keys and
code 0x5C) to PrxDecrypter.
It is not the whole fix yet: pspDecryptPRX() tries decryption types 0, 1, 2, 5
and 6, and this needs type 9, which JPCSP passes explicitly. So the call is now
reached and fails cleanly with a logged error instead of trapping, but does not
yet decrypt. Type 9 is a variant of type 2 and is the next job; the notes in
docs/VSHBootInvestigation.md say where it is in JPCSP and how to check a port
(159 bytes out, starting "release:").

Mostly small stubs:
- sceImpose: GetParam/SetParam/Changes/SetStatus, plus the 6.60 alias of
sceImposeGetBatteryIconStatus. Also fixes that function's first output - it
is a plain "is it charging" boolean, not a BATTICON_ value. We wrote
PSP_IMPOSE_BATTICON_NONE (0x80000000) there, which games ignore but which the
VSH reads as "no battery" and draws the empty-battery indicator for. These
are the bulk of the traffic: the VSH calls sceImposeChanges once a frame, so
this alone removes ~10000 trapped calls from a boot.
- SysMemForKernel: sceKernelSetRebootKernel, sceKernelSetUmdCacheOn.
- scePower_driver: scePowerSetWakeupCondition.
- sceHprm_driver, sceUsb: one NID-named call each, as in JPCSP.
Three groups are deliberately left unresolved, with comments explaining why,
because resolving them lets real flash0 drivers walk into hardware we do not
emulate and the boot dies where it used to reach the shell:
- ThreadManForKernel mutex/fpl NIDs: the NAND and ID storage drivers use these
to init, then poll the NAND controller at 0xbd101300 forever.
- InterruptManagerForKernel intr registration: 31 calls, then a stall in GE
list execution with no plugin module ever started.
73 unresolved import hits over 37 distinct module/NID pairs remain in a VSH
boot, mostly sceSysEventForKernel, sceSuspendForKernel and the various
*_driver modules that need real hardware behind them.
The sceImpose savestate section goes to v2 for the two new state variables.

ModuleMgrForKernel/0xD5DDAB1F is how the VSH loads its own plugins. The XMB's
interface lives in flash0:/vsh/module/*_plugin.prx and vshmain pulls those in
through this kernel call rather than the user-mode sceKernelLoadModule, so the
existing note that vshmain never imports sceKernelLoadModule was true but
incomplete - it imports this instead, and it was unresolved.
The consequence was quiet: vshmain got no module id back and then called
sceKernelStartModule with id 0, which failed with UNKNOWN_MODULE. None of the
plugins that populate the XMB ever ran. The scene still had its containers,
which is why every frame set up render state per node and drew nothing inside
them - the "6x render-state-setup, 0 draws" symptom this investigation has been
chasing.
Also implements 0xD86DD11B sceKernelSearchModuleByName, the other unresolved
ModuleMgrForKernel import.

For some reason, a pointer used to allocate the heap for scePaf is not
initialized. This hacks aroung that.
Additionally zero out the specific 4-byte "category 1 alarm count" address in vsh_module.
This gets us much further.
Extends the SysconSerialMMIO stub added for VSH boot into a real command/
response protocol matching uofw's Syscon_cmd() reference exactly (packet
framing, checksum, GPIO4 "response ready" handshake via a new GpioMMIO
cross-module hook), with handling for NOP/read-write clock/read-write
alarm commands.

Adds GameInfoFlags::BUNDLED_UPDATE_INFO, holding the version, title, size
and timestamp of the updater in PSP_GAME/SYSDIR/UPDATE. It comes from the
PARAM.SFO and the directory entry next to the archive, so it's a couple of
small reads on the ISOFileSystem the worker already has open - no
decryption, and DATA.BIN itself is only sniffed for its magic. Only
computed for ISOs; everything else is marked complete with an empty struct.
ISOFileSystem now parses the date out of the ISO9660 directory record,
stored as Unix UTC seconds and reported as the PSP's atime/ctime/mtime.
Those used to always read back as zero, so games calling sceIoGetstat on a
UMD file saw 1900 where hardware gives the mastering date.
Shown on GameScreen as e.g. "Firmware update on disc: 6.60 (2011-10-05),

Plenty of strings are legitimately identical in the target language - "Vsync",
"Status", "Ad Hoc multiplayer" - but the only test we had for "is this
translated" is "does it differ from English", so those got sent to the AI again
on every single run of finish-language-with-ai, costing tokens and giving it
another chance to translate something that shouldn't be.
They now get a "# same as English" comment and are skipped. finish-language-with-ai
writes it when the AI hands the English string back unchanged (which the
validation added earlier was throwing away as an error), and import-single writes
it when a language's line matches the en_US one. Deleting the comment puts the
key back in play.
Also stop comparing values with their comments still attached while working out
what's untranslated, which was leaking "# AI translated" into the context block
of the prompt.

It skipped the reference file, so adding a new string meant running
add-new-key-value first just to get the key into en_US.ini (and, as a side
effect, the English text into all 46 other files whether they were about to be
translated or not). Now an en_US line in the imported file is treated like any
other language, minus the "AI translated" comment, since that one is the string
the others were translated from rather than a translation.
So the workflow is one command plus validate. Languages left out of the import
simply don't get the key, and fall back to the English string at runtime -
copy-missing-lines is still there if you want the placeholder written out.
Instructions in AGENTS.md and the /add-string command updated to match.

Translating a UI string well means knowing what it does - what widget it is,
what the placeholders hold, how the neighbouring strings in that language are
phrased. langtool's AI commands can't know any of that, which is why their
prompt has a hand-maintained glossary that grows every time someone spots a bad
translation. An agent working in the repo can just go look.
So: AGENTS.md now describes doing the translating that way and letting langtool
do the file surgery (add-new-key-value, import-single, validate) instead of
hand-editing 47 files, and .claude/commands/add-string.md wraps it as a slash
command. Both say to skip a language rather than guess at it - the English
fallback is fine, a confident wrong translation nobody can proofread is not.

57 strings across nine language files:
* 33 in km_KH where a space snuck in between the % and the digit ("% 1"), plus
one where "%0.2f Hz" ended up as "0.2% f Hz".
* fa_IR "Quick chat %1" had the %1 replaced by a Persian numeral, and ko_KR
"Submitted %1 for %2" lost its %2.
* tr_TR "Earned" had the key translated instead of the value, so the whole
sentence with its four placeholders was replaced by the word "Earned".
The new Turkish string needs a look from someone who speaks Turkish.
* 20 strings across five files that were wrapped in quotes. PPSSPP's ini parser
strips those on load, so nothing changes on screen, but they tripped the
validator.
Turkish writes percentages as "% 0", so the "% <digit>" fix was only applied
where it makes the placeholders match the English string again.

finish-language-with-ai maps the English string the AI translated back to the
key it belongs to, but the map was keyed on the English string, so when two keys
in a section share one - [Graphics] "Texture Filter" and "Texture Filtering",
[Error] "Error reading file" and "The file is not a valid zip file" - only the
last one survived and the other silently never got its translation.

Placeholders like %1 and %d have to survive translation intact, and they don't
always: the new "validate" command finds 37 strings across four language files
where one got dropped, localized into another script, or split with a space.
It also catches empty translations, line breaks and stray quotes, and exits
non-zero so it can be used as a check in a script.
The same checks now run on everything the AI returns, before it's written to a
file - plus a check that it didn't just echo the English string back at us. A
language that fails is skipped instead of aborting the whole run.
