Booting the VSH with a disc now stays in the XMB, with the disc in the
Game column, rather than starting the game right away.

KeyValue gets an optional pointer to a g_Config bool, which the key
reads as 0/1. The setting wins over guest writes: since category_version
is kept low, the VSH upgrades the registry at every boot and rewrites
every key with its default.
/CONFIG/SYSTEM/umd_autoboot reads the new SystemParam VshUmdAutoboot
(default true, as before). Turned off, --vsh --mount stays in the XMB
with the disc in the Game column instead of starting it.

Tilt used the raw accelerometer as the gravity vector, which jitters with
sensor noise and jumps when the device is shaken. Now, when gyro data is
coming in, a complementary filter integrates the gyro rates and only pulls
the result toward the accelerometer with a 0.5 s time constant, trusting
the accelerometer less the further it reads from 1g. The fused vector goes
through the same ProcessTilt path, so calibration and sensitivity work as
before. Without a gyro, nothing changes.
The fusion lives in TiltEventProcessor behind NativeGyroscope(), so other
sources (DualSense) can feed it too. Android registers TYPE_GYROSCOPE next
to the accelerometer. A "Use gyroscope" checkbox (on by default, per game)
appears in tilt setup once gyro data has been seen.

MeCore owns a second MIPSState in the ME's address space, held in reset
until released (SetReset). It runs on the interpreter, a slice behind the
main CPU: CoreTiming runs it for the cycles the main CPU has just used, in
Advance and ForceCheck. Its own PRId (COP0 22) and mfic/mtic flag; MMIO
counts as kernel mode on it, and a syscall stops it with an error rather
than reaching HLE. The interpreter's block stepping reads delay slots
through the stepping CPU's memory, and cache instructions log at verbose
level, as ME code flushes its caches in a loop.
Created at boot only for homebrew (PBP with MG category or no SFO, ELF;
the VSH counts, as vshmain.prx loads as an ELF), when "Enable ME
emulation for homebrew" is on: a global checkbox in developer settings,
off by default and not translated yet, or --me-core. Saved in its own
section after MMIO (SaveStart v5), with its own memory; loading a state
creates or removes the ME to match.
The boot page now starts with a reset stub that sends the ME on to
0xBFC00040, where homebrew puts its code (from the firmware's reset code,
read on a PSP-1000).

"Compress game" in the game screen's ... menu, for ISO, CSO, CHD and PSN
EBOOT.PBP games. It opens a list of the CSO presets (and Extract to ISO
for anything that's not an ISO already):
- Best: libdeflate level 12, 64K blocks
- PSP Compatible: zlib level 9, 2K blocks, readable by custom firmware
These match maxcso's presets, and the CSOs come out byte-identical to its.
The writer, Core/FileSystems/CSOCompress, reads the input through PPSSPP's
own block devices, so recompressing is a single pass with no temporary
file.
The original is deleted when done, unless "Keep the original file" is
checked (off by default). When the new name is taken, by a kept original
or another file, a number is added to it.
The work runs on a thread using every core, with a progress bar and time
left at the bottom of the game screen. It keeps going when the screen is
left, and the ... menu offers Cancel meanwhile. On the game list the
game's icon is covered by "Compressing...", and clicking it opens the
game screen instead of playing. When done, recents follow the new file
and the game screen and lists refresh.

They get their graphics context from the frontend, so they compiled and
linked the Metal backend without being able to use it. Adds
PPSSPP_API_METAL, like PPSSPP_API_D3D11, for the code that only exists
with it.

The range check predates GPUBackend::METAL (4), so the setting was lost
on every load, and the app came back up on Vulkan.

thin3d on Metal, plus a small render manager that owns frames, command
buffers, lazily started render passes and a per-frame push buffer.
Shaders are the same Vulkan GLSL the Vulkan backend gets, translated to
MSL through glslang and SPIRV-Cross, with the Vulkan binding numbers as
Metal buffer/texture indices. flip_vert_y makes Metal's clip space match
Vulkan's, so everything else follows the Vulkan conventions.
Adds GPUBackend::METAL (4) and builds the files on Apple platforms. Not
yet selectable: the SDL window setup, the UI choice and the GPU core
come next.

The bit-exact VFPU dot product is the default everywhere and fast enough,
so the plain multiply-add paths in the interpreter and the IR frontend go,
along with the AccurateVdot setting, --accurate-vdot, the ForceAccurateVdot
compat flag and the Vec4Dot IR op, which nothing emits any more.

Recent gets the view mode and grid settings buttons. It has no path,
nothing to navigate, and its list comes from memory, so the path,
navigation and refresh stay out. Its old grid setting is no longer
migrated, like Games and Homebrew.

The accurate dot products cost a few percent at most in the IR JIT, apart
from GTA (about 20% on a game that's cheap to run anyway). The fuzzer follows
the default too, unless PPSSPP_CPUFUZZ_ACCURATE_VDOT=0.

Not wired to anything yet. It will make every core compute the VFPU's dot
products (vdot, vmmul, vtfm and the rest) bit-exactly like the PSP, through
vfpu_dot().

Killzone: Liberation's Chapter 5 DLC is an installer that the PSP turns
into ms0:/PSP/GAME/<id>/KZL.PRX, which the game loads with
sceKernelLoadModuleDNAS. That file is a PGD around a type 3 PRX (decrypt
mode 18), both keyed to the console that installed it. Its Fuse ID
gives everything needed:
- libkirk: the per-console key derivation, and KIRK commands 3, 5 and 8
built on it (KIRK ROM per uofw, key mesh per psdevwiki).
- PrxDecrypter: type 3, which is type 5 with the first step through
KIRK command 3 (JPCSP's PRX.java), and the DNAS PGD unwrap.
- sceKernelLoadModuleDNAS uses the new FuseID setting (or --fuse-id).
Without one, or with the wrong one, the game falls back to its stock
module and an OSD message says why.
- Headless --re-decrypt takes --re-decrypt-key and --fuse-id, to decrypt
such a file offline.
Verified with a patch installed on a real PSP: the v1.20 module loads,
starts and reads CHAPTER5.BIN. Type 5 output is unchanged (an NPJH50521
PBOOT.PBP decrypts byte-identically). How to install one over PSPLink is
in docs/dnas-patches.md.

The IR-based one replaces it. With that, every native JIT is IR-based, which the JIT viewer and
the settings' comments now assume. The ARM emitter test loses its part that drove the old FPU
register cache.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Their IR-based replacements stay. The JIT core now creates the IR JIT on both, so "JIT using
IR" is the same as "JIT" on every architecture (ARM32 still uses its legacy JIT for both). The
settings no longer offer it, a saved JIT_IR loads as JIT, and the JIT harness and CPUEquivalence
fuzzer drop the duplicate run.

The old GridView keys are now read as ints, so a missing key can be told

A third view mode next to grid and list: a list with full size icons,
scaled by the grid icon size setting. Like the XMB, the selected (or
hovered) game plays its ICON1.PMF in place of the icon.
The per-tab grid bools become GameBrowserView1-4 ints. The old GridView
keys are still read, to pick the default, but no longer saved.
The PMF decoding moved out of GameScreen's PMFView into a shared
PMFVideoTexture.

The app now always uses the Metal view controller with Vulkan (MoltenVK),
for both the App Store and sideload builds. The GL view controller is gone,
and Common/GPU/OpenGL (except GLFeatures, used by the shader generators) and
GPU/GLES are no longer compiled for it. PPSSPP_API_ANY_GL is now off for
all of iOS except the libretro core, which still uses GLES.

The C++ paths draw and sample four pixels at a time in vector lanes,
while a JIT function only does one, and with a JIT function in use the
span and quad paths were skipped. On x86 the JITs had become slower:
Wipeout took 13% more wall time and 25% more CPU with them, God of War
3% more. They were also a second implementation of every GE rule, and
ARM never had them.
The SoftwareRendererJit setting goes with them. RasterizerRegCache.h
keeps only the types the pixel and sampler functions take, as
RasterizerTypes.h.

Most UMDs carry a firmware updater, and having a real firmware in the NAND is
what the LLE modules want. On boot, if the disc's updater is newer than what's
installed - or nothing identifiable is installed, which is what a fonts-only
NAND looks like - unpack it, with a progress bar on the OSD. Controlled by
bAutoUpgradeFirmware, on by default, with a checkbox on the firmware screen.
Off in headless, which shouldn't rewrite the NAND during a test run.
The install itself is now shared with the install screen, and hardened, since
it can run without anyone watching:
- It stages into <NAND>/install-staging and only erases the installed firmware
once the new one is complete on disk, so a failure leaves what's there alone.
- A single entry that didn't unpack fails the whole install. A firmware with
holes still looks installed, so nothing would ever replace it.
- A truncated archive is rejected instead of unpacking to half a firmware that
every stat reports as a clean install. The PSAR header records the length;
it was being clamped to the buffer rather than checked against it.
Also falls back to the version in the archive's own header when the PARAM.SFO
next to the updater is unreadable, which it is on a fair number of discs.

The log was trimmed to 50 lines, which isn't enough to scroll back
through a conversation - now 250. Chat entries also carry the time they
arrived, shown as a dimmed HH:MM in front of the name, behind a new
"Show timestamps in chat" setting.
The timestamp is kept next to the text rather than baked into it, since
the chat view finds the sender by splitting the line at the first colon.

GetStringErrorMsg had the strerror_r result test backwards. The XSI variant returns
0 on success, so every successful lookup returned "Unknown error"; and under glibc
with _GNU_SOURCE the GNU variant is selected instead, which returns the message by
pointer and typically leaves the buffer untouched, so it returned an empty string.
Either way GetLastErrorMsg() was useless on Linux, Android and macOS. Pick the right
handling by overload resolution rather than guessing which signature we got.
KeyMap's "no gamepad button mapped to cancel" fallback pushed into confirmKeys
instead of cancelKeys - and pushed the confirm button. So unmapping cancel left no
gamepad way out of menus, and duplicated an entry in the confirm list.
ControlMapper::AddListener mutated listeners_ without taking mutex_, while
RemoveListener takes it and the input thread iterates the vector under it. Opening a
screen while an axis is moving could reallocate it mid-iteration. The comment about
piggybacking on a screenmanager mutex was stale - there isn't one.
Config's two std::stof calls on PostShaderSetting values ran on user-editable ini
text with no try/catch, so a malformed entry called std::terminate during startup
config load. Use the same checked sscanf that LoadGameConfig already uses.
(CmdLine.cpp and Compatibility.cpp have the same pattern; not touched here.)
The screenshot downscale path leaked its final buffer on every downscaled shot,
which savestate thumbnails hit on every save at 3x and above.
HandleUploadPost is registered unconditionally, so closing the Upload screen left an
unauthenticated file-write endpoint live for as long as anything else kept the server
up. Check the flag in the handler.

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.

SymbolMap:
- Fix GetModuleIndex(): it only checked the end of an active module's range
(via activeModuleEnds.upper_bound), never the start, so an address sitting
in the gap before a module was silently misattributed to it. Added
GetModuleIndexByName() as a companion lookup.
- AddModule() gains an optional crc param, stored per ModuleEntry. Reactivating
a module by name now also requires the crc to agree when both sides know it,
so two unrelated binaries that happen to share a name no longer get merged
into one symbol table (addresses the old TODO at the top of SymbolMap.h).
- AddLabel()/AddFunction() gain an updateName param (default false, preserving
existing "first writer wins" behavior) so a trusted source - like a loaded
symbol file - can be allowed to overwrite a name that a lower-confidence
automatic pass already assigned.
- New SaveModuleSymbols()/LoadModuleSymbols()/GetModuleSymbolsPath(): save or
restore one module's functions/data/labels to/from a small human-editable
text file, addressed relative to the module (so the file stays valid however
the module ends up positioned on a later run). Keyed by
PSP/SYSTEM/SYMBOLS/<moduleName>_<crc>.ppsym - deliberately by module+crc
rather than by game, so it's shared by every game/homebrew that loads the
exact same module. A "# game <id> <title>" comment records who last saved
it, informational only.
WebSocket debugger: hle.module.saveSymbols/loadSymbols expose the above.
sceKernelModule.cpp: auto-load a module's saved symbols right after it's
registered with the symbol map (both the real ELF-load path and the
savestate-load path), and auto-save on unload (before UnloadModule(), while
its symbols are still active) - gated behind the new bAutoSaveLoadSymbols
config setting (default off), with a matching Developer Tools checkbox and
a --auto-save-load-symbols command-line override for headless use.
Includes some in-progress cleanup already staged: DescribeAddress now calls
g_symbolMap->GetDescription() directly instead of through the now-removed
MIPSDebugInterface::getDescription() wrapper.

Our Qt backend has long been left behind and doesn't even support Vulkan
currently. There would be a lot of work to make it viable, and I don't
think anyone is really interested.
ImGui on SDL will soon fulfill the need for a more classic user interface
with a menu bar on Linux, and on Mac we already have a native UI.
