The 1.00 updater's DATA.PSAR is a version 1 archive, the only one there is,
and its blocks carry tag 0x06000000, which the PRX decrypter had no key for.
1.50's mesg_led.prx keeps its keys raw in a table after their tags, the
0x0E000000 one we already use among them, and the 0x06000000 one there
decrypts all of 1.00 (with KIRK code 0x49, following the other tags). Its
first record has no version text either, so the version now comes from the
firmware's own version.txt when that's missing.
Fix a zlib usage bug.
Headless --unpack-updater also exited 0 when every file failed, so now it
fails if any did.

Family Guy and The Dark Knight are coded as separate field pictures,
bottom field first. ffmpeg hands each pair back as one frame, and we
described it with the first field's SEI record only.
The UMD Video player (video_main_plugin.prx) shows such a picture a field
per vsync, and takes the field order from comparing the output times of
the picture's two records. With the second left empty it always chose
top first, so every pair ran backwards in time and the picture jittered
between frames. Now the pair carries both fields' timing, the top field's
record first.

The XMB's video player renders Motion JPEG AVIs with sceMpegBaseYCrCbCopyVme
and sceMpegBaseCscVme (JPCSP's names), which take planar YCbCr in two halves
rather than the ME's tiled layout. The copy sizes follow mpegbase_260.prx.
sceMpegBaseYCrCbCopy took the frame size from the destination descriptor,
which the same player leaves unset. mpegbase_260.prx reads it from the
source, in pixels.

A CD CHD is read through its track metadata: each track's frames are
padded to a multiple of four, a pregap is stored only when its type
starts with V, and audio is big-endian. A .chd that's a CD is a PS1 disc,
PSP discs being DVDs. The FileLoader-backed core_file the PSP CHD block
device used is now OpenCHDThroughLoader(), for both.
An .mds gives each track's start, pregap and length, and where in the
.mdf it's stored, with 96 bytes of subchannel data after each sector.
Anything between tracks isn't stored. A bare .mdf goes through its .mds,
which the game browser lists, and archives install with both.
MODE2/2336 cue sheets, which only had their sector headers made before,
are now tested too.

A cue sheet, a CloneCD .ccd, or a bare .bin, .img or .iso of a PS1 disc
now boots on the firmware's POPS, as the converted EBOOT.PBP popstation
would make from it. PS1EbootFileLoader builds the PBP header, PARAM.SFO
(the disc ID from SYSTEM.CNF) and the PSISOIMG header, TOC and block
index, and serves the disc image from the image's own files. Each block
of 16 sectors is a stored DEFLATE block: the manager won't read an image
of uncompressed blocks in its own format, but the converted PBP's inflate
takes stored ones, and with every block the same size, reads map straight
onto the files. Nothing is compressed or written anywhere.
Cue sheets can have any number of files, AUDIO tracks, INDEX 00 and
PREGAP, and a missing FILE falls back to the cue sheet's own name. A
2048-byte .iso gets Mode 2 Form 1 sectors made around its user data.
The EBOOT is mounted as the only file in host0:, through BlobFileSystem,
which now saves its open handles in savestates. The game browser lists
.cue, .ccd, .bin and .img, leaving out the .bin and .img files a cue
sheet or .ccd next to them describes, and a bare image opened directly
goes through the cue sheet that names it. GameInfoCache reads the title
and ID of these, and of real PS1 EBOOTs, from their PARAM.SFO.

A disc game or memory stick EBOOT started from the XMB used to be swapped in under the XMB's session,
so it ran without its PARAM.SFO, compat flags, game config, window title, savestates and so on.
Much of that is decided once, at boot (the memory map, the GPU backend, the shader cache), so
sceKernelLoadExec now asks the frontend for a reboot into the disc image or EBOOT (PSP_RequestBoot)
and stops. The app and headless boot it like a game from the game list.
The game keeps the XMB's launch args (CoreParameter::launchedFromVSH), so exiting boots the XMB
again, with the disc that's in the drive and those args, and the XMB comes back where it was without
auto-starting the disc. Homebrew keeps the disc that was in the drive. A disc whose executables are
all zeroes (the EUR Video Demo Disc's "game") still loads in place and fails back to the XMB.
In headless, the run carries on through the reboot, starting stopped under the debugger like the
first boot, since the reboot loses a pending cpu.runUntilTime.

The game list already did, but booting a video disc any other way (the command line, a file
association, dropping it on a running game, headless) tried it as a game and failed. The loader now
swaps in vshmain.prx with the disc mounted and auto-start on whenever it identifies a UMD Video
disc and the installed firmware can play it. GetUmdVideoVSHPath() moves from the UI to
Core/Util/PSARUnpack.

With firmware 2.71 or later installed, picking a UMD Video disc boots the XMB with the disc in the
drive and UMD auto-start forced on for that boot, so the disc's menu comes up. Without one, the
info screen saying UMD Video isn't supported shows as before. The info screen's Play does the same.
A disc with both a game and video asks which to start. For the video, the XMB comes up with
auto-start forced off, since auto-start runs the game.
Older firmware can't play these: 1.50, 2.00 and 2.60 crash in video_plugin or paf with a video disc
in the drive, and 2.50 refuses it. 2.71 through 6.61 reach Bourne Supremacy's menu.

Post-shader framebuffers (for shaders at output resolution, and those
that keep the previous frame) are sized for the output they were built
for. Moving the game to a TV or back, or the TV changing size, left them
sized for the other one. SetOutputOverride now asks for a rebuild when
the output changes.
Also corrects the design doc: "auto" render resolution follows the
device's screen, not the TV.

Graphics > "External display" on iOS and Android. "Show the game" (the
default) is the TV mode, "Mirror the screen" leaves the TV to the system.
A change applies right away. It's disabled on backends that can't draw to
a second swapchain.
On Android 12 and up, a second screen that's part of the device (like a
dual-screen handheld's) isn't used, so the game doesn't move there by
itself.

A presentation display (HDMI or USB-C video out, some wireless displays,
or the simulated ones in Developer options) gets a Presentation with a
SurfaceView, whose surface becomes a Game output, when the backend is
Vulkan. Otherwise Android keeps mirroring.
The surface mustn't be touched after surfaceDestroyed returns, so the
output is removed with the new Native_RemoveOutputAndWait(), which
returns once the render thread has let go of it (or right away if the
graphics are down). The UI drawn on an output now leaves out the main
swapchain's pre-rotation, as the game already did.
"In menus on %1" gets the device name from Settings.Global.DEVICE_NAME.

Updates the submodule for video/mp4/avchold's ref3b1hrdsplice, recorded
on a PSP, which fails without the AvcDecoder fix on this branch: the pictures after
the splice never come out.
avchold and decodeend only test anything with Sony's mpeg and mp4
modules running, which headless never does for homebrew unless asked,
and which CI doesn't have. docs/pspautotests.md now says how to run
them (--disable-hle=0x110 and a memory stick with a firmware dump).

Swapchains other than the main one are VKRSwapchains, owned by the
render manager, each with its own surface, image views, framebuffers
and depth buffer, in the main swapchain's format so the backbuffer render
pass and pipelines work for all of them. A render step with no
framebuffer can name one.
They don't pace the frame: acquiring doesn't wait, and the pass is
skipped if there's no image. The frame's last submit waits on and
signals the semaphores of every swapchain acquired that frame, and each
is presented after the main one. When one goes out of date, it's
recreated at the start of the next frame.
The main swapchain's path is unchanged; frametests on Vulkan match.
VulkanContext::CreateSurface is the old per-platform surface code, now
also used for the extra ones.

The 1080p cap was meant to save Wi-Fi bandwidth, but an Apple TV 4K
only offers 3840x2160 over AirPlay, so the stream was 4K anyway, just
upscaled.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An external display (like an Apple TV over AirPlay) becomes a Game
output, when the backend is Metal. The game is shown there full screen,
and the phone shows the touch controls with "Playing on TV" in place of
the game. The menus stay on the phone. With other backends, iOS keeps
mirroring.
Up to iOS 26 the external display scene comes from the Info.plist role.
iOS 27 ignores that, and only offers the scene to apps that register a
scene accessory for it, so we do that too. The registration is withdrawn
when the view controller shuts down, so it follows a backend change, and
a restart now goes to the app's scene rather than the first one.
An Apple TV 4K only offers 3840x2160 over AirPlay, so the stream stays
4K, but we render at 1920x1080 and let the layer scale it up.

The backbuffer is now a Swapchain, from GetPrimarySwapchain(), and
callers bind, measure and read it back through that instead of nullptr.
nullptr still means it too. Backends with one swapchain map the primary
to their old backbuffer path.
On Metal, CreateSwapchain() adds more, each with its own layer, depth
buffer and drawable. Passes merge per swapchain, and Present() presents
every drawable acquired that frame. The backbuffer is just the first
of them. Nothing creates a second one yet.

Not on tvOS, where the Metal backend hasn't been run yet. Existing
installs keep the backend saved in their ini.
The multi-swapchain plan now does Metal before Vulkan to match.

It was left unresolved with the kernel mutex calls, as they all let the
flash drivers reach the NAND controller during a VSH boot. It's the
mutexes that do that: with only the FPL resolved, sceIdStorage_Service
allocates from its pool and every firmware's VSH in 1.50-6.61 boots to
the same XMB picture as without it. Resolving the mutexes still hangs on
0xbd101300.

Inserting and ejecting a disc there adds and removes the umd0:/umd1:/
umd:/disc0: mounts, and MetaFileSystem's state pairs sections with mounts
by position without recording which disc was in. A state could then fail
to load, or load one disc's open files onto another. The pause screen
already hid its save buttons for vshmain.prx; the save hotkeys, rewind,
the ImDebugger and the WebSocket debugger all went around that. The check
is now in SaveState itself, and rewind snapshots aren't taken. Verify
still runs, since it reads back with the mounts as they are.
A proper fix records the mounted image in sceUmd's state and remounts it
on load.

The XMB, booted without a game, now starts with an empty drive: when
vsh_module loads with nothing at disc0:, the drive is marked empty, and
activating it tells the shell's drive callback (SceVshMediaDetectUMD)
there's no disc. Activation used to report a readable disc regardless,
so the shell asked for its type and showed "The disc could not be read."
The disc type devctl (0x01F20001) answers 0 without a disc, as JPCSP
does.
game.umd.insert (path) mounts a disc image into the empty drive and
calls the drive callback as inserting one does; game.umd.eject takes it
out. UmdMount() is UmdReplace() without its need for a disc already in.
Inserted into the 6.61 XMB, Daxter shows in the Game column with its
icon, background and animated preview, and launching it boots the game
to its title menu.

-i, -j, -r, -J, --ir and --jit-ir are gone. -r was also --root's short form,

-i, -j and -J now fail with an error pointing at --cpu= instead of quietly

How the firmware's POPS manager and emulator are booted, what stands in for
the Media Engine, what's patched in them, the rendering changes they need,
and what's not done yet.
--press=SECONDS:MASK[:DURATION],... holds sceCtrl buttons at emulated
times, and --screenshot-at=SECONDS:FILE,... saves screenshots along the way,
to drive a game past its menus in a run. With presses, the run loop steps
1/60 of a second at a time so short ones land.
HLEFunc and ReplaceFunc now take the MIPSState they run on. The dispatch
paths (both interpreters and every JIT backend) pass in the state they
belong to, and CallSyscall*, hleFinishSyscall and the HLE mips call
machinery use it instead of currentMIPS.
The wrappers in FunctionWrappers.h take the function as `auto` and call it
through HLECall, which also accepts an implementation with an extra leading
MIPSState * parameter and passes the state to it. Any other signature still
fails to compile, as before. PARAM/RETURN now refer to a local `mips`.
The HLE functions (and replacement functions) that used currentMIPS now take
the state that way. Callers outside a syscall's own frame - CoreTiming
events, the adhoc matching thread, dialogs, PPGe, the debugger UIs - pass
currentMIPS or &mipsr4k explicitly. The kernel's thread internals still use
currentMIPS.

The game boots until the queued state is read, decompressed and applied, which takes a varying amount
of host time, and those boot frames counted towards the timeout. So the same state ended on different
frames depending on the host, for example while texture replacements competed for the IO threads.
After the load the emulation is identical: syscall traces of Fate/Extra CCC with no texture pack, and
with one loading slowly or instantly, are byte for byte the same.

A save to a path with a save still being written counted as a repeated
key press, even with a load applied in between, so save, load, save
didn't save the loaded state. Now a repeat only joins the earlier save if

game.state.save and game.state.load take a slot of the running game

A rewind used up the state it restored, so rewinding, playing on a bit and
rewinding again went further back than the state you just came from. Now
the state stays, and only a rewind within 0.8 seconds of the last one
steps back past it.
"Seconds ago" was wall-clock time since the snapshot, which counted
pauses, fast-forward and time spent in states rewound to earlier. It's now
emulated time from where the rewinding started.

Same as game.state.load/save, and the wait response now carries the
metadata string (for a rewind, how long ago the snapshot was taken).
Also fixes Broadcast() erasing a waiting entry while holding its mutex,
which could free the mutex while locked (the debug CRT aborts on it).

Like the Vulkan backend: a multisampled framebuffer has multisampled
color and depth textures that are drawn to and kept between passes, and
each pass resolves them into the ordinary ones (depth and stencil to
sample 0), which textures, copies and readbacks use.
BindFramebufferSamplesAsTexture binds the samples, for the shared code's
sample 0 copies. Copies between multisampled framebuffers copy the
samples too, both depth and stencil, since Metal can't copy one plane of
a multisampled texture.
Also skips empty draws, which Metal doesn't allow.
With 4x MSAA, 1012 of the 1061 frame dumps are identical to Vulkan's.
Most of the rest differ at edges because programmable blending blends
each sample with its own color. In Resistance: Retribution, the sample 0
copy for a palette lookup matches the render without MSAA here, and
Vulkan's doesn't.

With wait: true, respond once the savestate operation has finished (with its

A log-only breakpoint in a hot loop fills the per-connection queue, and the

Loading a savestate kept the current session's netAdhocInited,
netAdhocctlInited and matching-inited flags rather than the saved ones.
Loaded into a fresh boot, a state saved with adhocctl initialized (but not
connected) then failed every adhocctl call with NOT_INITIALIZED. MGS Peace
Walker shuts ad hoc down before a cutscene and retried
sceNetAdhocctlDisconnect forever, leaving the screen black.
Take the flags from the state, and bring the host side in line: start the
friendFinder and log in again when the state has adhocctl up and we don't,
stop it in the opposite case. Also save the product code, which that login
sends.
Also add a game.state.save debugger command, used to reproduce this.

iOS only runs app bundles, so with HEADLESS=ON the iOS build makes
PPSSPPHeadless an app (org.ppsspp.headless) that starts UIKit and runs
the headless main on a thread with the arguments devicectl launched it
with. Vulkan only, and the IR interpreter since there's no JIT.
frametests.py --ios installs it, copies over the dumps the device lacks,
and compares each render with the host's Vulkan one like --adb does.
Each devicectl call costs a second or two, so the new --screenshot-dir
