Sign-in, web browser and player dialogs finish cancelled; the message dialog finishes at once;
NpAuth, entitlement consumption, reachability, account age and the NpUtility bandwidth test
report signed out; sceKernelMtypeprotect changes the protection (the memory type has no host
equivalent); the APR ForEach resolvers resolve every path and report each failure in its own
result entry. vswprintf's stub is dropped in favor of the existing wide-formatter
implementation, which already covers it on every platform.

scePadOpen now records that the pad is open and scePadClose clears it;
scePadGetHandle returns the handle for a port scePadOpen accepts while
the pad is open, and DEVICE_NO_HANDLE otherwise. No embedded microphone
is emulated, so the option that weakens trigger vibration while it is
in use is accepted with no effect.

Ten libSceVideoOut and two libScePad error constants had values that
belong to other errors of the same library (for example INVALID_HANDLE
was 0x80290003 and RESOURCE_BUSY / SLOT_OCCUPIED were swapped). They now
match KytyPS5, shadPS4 and fpPS4, which agree on all of them.

The title is fully installed, so scePlayGoGetLanguageMask reports every
language. scePlayGoSetToDoList validates the handle, entries, chunk IDs
and loci; nothing is pending, so the list is not kept.

BAD_POINTER, BAD_HANDLE and BAD_SIZE were 0x80B20004, 0x80B20005 and
0x80B2000D, which are INVALID_ARGUMENT, NOT_INITIALIZED and BAD_SPEED.
They are 0x80B2000A, 0x80B20009 and 0x80B2000B.

sceFiberStartContextSizeCheck and sceFiberStopContextSizeCheck toggle a
mode in which new fibers get their context filled with a pattern, so
sceFiberGetInfo can report the unused stack margin.
sceFiberGetThreadFramePointerAddress returns the frame pointer of the
thread that called sceFiberRun.

Keyboard input follows libSceMouse: the video out event loop forwards SDL
key and focus events, whose scancodes are USB HID usages, and the library
keeps the pressed keys, modifiers and lock LEDs in a 16-entry history for
sceKeyboardRead and a snapshot for sceKeyboardReadState.
sceKeyboardGetKey2Char translates the 101-key arrangement; the 106-key
one throws and is listed as technical debt.
KeyboardData holds 16 key codes (96 bytes), not 6.

sceCesRefersUcsProfileCp1252 returns the CP1252 profile, and
sceCesSbcToUtf8 / sceCesUtf8ToSbc convert one character in each
direction. The five bytes CP1252 leaves undefined map to the matching
C1 controls, so every byte round-trips. Malformed UTF-8 and code points
outside CP1252 return the library's error codes.

sceSslGetCaCerts reports that no CA certificates are available and
sceSslFreeCaCerts clears the structure, in line with the library's
no-network behaviour. sceHttp2AbortRequest succeeds like
sceHttpAbortRequest. sceSslClose and sceSslGetSerialNumber keep throwing
and are listed as unknown signatures.

sceHttpUriParse, sceHttpUriBuild and sceHttpUriEscape work on strings
only and are implemented. sceHttpCreateRequestWithURL, sceHttpReadData,
sceHttpSetChunkedTransferEnabled and sceHttpCreateEpoll follow the
existing no-network behaviour.

A 16-bit VOP1/VOP2 result in SDWA form with dst_sel:DWORD writes the whole register, so with
dst_unused:UNUSED_PAD the high half is zero. write16Bits treated dst_sel:DWORD as the plain
encoding and kept the old high half, which is right only for the non-SDWA form (GFX10 16-bit
instructions preserve the high bits). The decoder already marks SDWA destinations with
explicitSdwaDst; write16Bits now sends those through writeRawU32 like the other selectors.
GFX10 compilers rely on this to zero-extend f16 results before packing two of them with an
integer add, e.g. v_cvt_f16_f32_sdwa ... dst_sel:DWORD dst_unused:UNUSED_PAD followed by
v_lshl_add_u32 v2, hi, 16, lo. PPSA21564's FidelityFX depth-of-field combine pass packs its
near/far colours into LDS this way 60 times: whatever the low register held before leaked
into the high half, so green (and alpha) of the packed pairs came back huge or infinite while
red and blue stayed right. The bloom then spread the bad green over the intro cinematic.
agc_driver_sdwa_destination_tests runs the padded, preserved and plain encodings and the
packing idiom on the GPU against a model of the guest instructions.
decodeResult and decodeAllocation called memcpy with the data() of
empty vectors, which may be null. Passing a null pointer to memcpy is
undefined even for a zero size, and UBSan reports it on every entry
without push constants, including the existing shader disk cache test.
The copy now runs only for a non-empty table, as Reader::Values does.

In 64-bit mode a REX prefix only takes effect when it immediately
precedes the opcode; a REX followed by a legacy prefix or another REX is
ignored. The instruction decoder, the rewriter's reference classifier,
DecodedInstruction and the SSE4a, SHA-256 and CLZERO operand decoders
read legacy prefixes and then at most one REX. `48 F3 0F 2B 00`
(MOVNTSS) was therefore scanned as `[48 F3][0F 2B 00]` and kept, and
`48 67 0F 01 FC` lost its address-size prefix.
All of them now accept REX bytes among the prefixes and keep only one
that directly precedes the opcode. The converter's guard against
prefix-only fragments is removed, since the decoder no longer produces
them, and the TechnicalDebt entry describing the split is dropped.

Lower CLZERO out of line instead of failing the relink: the 64-byte line
containing rAX (EAX with 67h) is cleared with four MOVNTDQ stores of
zero, the same non-temporal, weakly ordered store. The line address is
masked in xmm0 so RFLAGS stays untouched; xmm0 and rcx are spilled below
the red zone. Short sites share stubs through MatchSequence. CLZERO with
LOCK, an FS/GS override, a 66/F2/F3 prefix or longer than 15 bytes fails
the relink.
The decoder splits a REX followed by another prefix into a separate
instruction, which would hide a prefix that changes what CLZERO or the
next instruction does. The converter now fails the relink when such a
prefix-only fragment directly precedes an AMD-only instruction or would
be moved into a stub as a trailing instruction.
