* Add internal render resolution scale and fix embedded surface DPI scaling
Adds a GUI-configurable internal resolution scale (Graphics tab) that
renders offscreen color/depth targets below native guest resolution
and upscales on present, trading image quality for GPU headroom.
Storage/UAV images and sampled asset textures are left untouched, and
texture-alias/feedback-loop lookups compare against each target's
logical (unscaled) size so scaled render targets are still found
correctly when sampled back.
Also fixes the embedded game surface not filling the window: the
isolated emulator child process had no declared DPI awareness, so
Windows silently downscaled every window-geometry query it made
against the GUI-owned surface HWND by the display's DPI factor,
leaving an unfilled black margin on scaled displays.

Add per-game launch overrides (log level, import-trace limit, strict dynlib
resolution, log-to-file, and SHARPEMU_* environment toggles) with three-tier
resolution (per-game override -> global preference -> built-in default), stored
one file per game at user/custom_configs/<titleId>.json. Editable from a new
"Game settings..." context-menu dialog.
Introduce a shared SettingRow control and adopt it across the Options page and
the per-game dialog so the two read as one app. Fully localized (reusing the
existing Options.* keys), with the actions pinned in the dialog footer.
* Latest commit info axamal structure
* Link latest commit to text
* Added localization for About>Last commit info
* Made the commit hash a button that redirects you to the commit in github
* Reorder about section
* Commit and update icon in about section to have consistency in section
* Boot compatibility fixes for UE titles, GUI toggles, and DeS render/boot work
Checkpoint of the Monster Truck Championship and Demon's Souls boot work.
Each piece is independently useful and verified against the titles.
- playgo: scePlayGoGetLocus now returns BAD_CHUNK_ID for chunk ids outside
the known set, matching real firmware. Titles enumerate chunk ids until
that error; answering OK for every id made the scan wrap the ushort range
and spin forever. Missing-sidecar and no-app0 fallbacks report a
fully-installed single chunk 0 so scePlayGoOpen keeps succeeding.
- kernel: restore the SHARPEMU_WRITABLE_APP0 opt-in. Unpackaged UE dumps
write their Saved tree under /app0 during PS5 component init and treat
the denial as a fatal boot error.
- pad: accept handle 0 as the primary pad across all pad calls. Real
firmware hands out small non-negative handles and some titles read state
with handle 0.
- bthid: env-gated experiment hooks for the Thrustmaster wheel middleware
investigation (fail-only-RegisterCallback modes and a synthetic
enumeration callback with a zeroed event struct). All default off.
- gui: add SHARPEMU_LOG_IO and SHARPEMU_WRITABLE_APP0 toggles to the
Environment tab.
- videoout: per-swapchain-image render-finished semaphores (the shared
semaphore raced the swapchain); whole-mip-chain layout init for offscreen
guest images (sampled binds read mips stuck in Undefined); GPU-resident
texture availability now canonicalizes through the texture format table
and accepts compatibility-class aliases, cutting per-frame CPU texture
re-reads (143 GB -> 55 GB per 300 s in Demon's Souls, 0.2 -> 0.5 fps).
- hle: add sceSystemServiceGetNoticeScreenSkipFlag,
sceSystemServiceGetMainAppTitleId (title id published from the runtime),
and sceNpWebApi2CreateUserContext (refuses so the online layer backs off).
- rtc: SHARPEMU_RTC_PROBE_RANGE diagnostic dumps the code around a busy-wait
caller of sceRtcGetCurrentTick once; costs nothing when unset.
* [ShaderCompiler] Fix VReadlaneB32 scalar destination field
The scalar destination lives in the low vdst byte (bits 0-7); it was read
from bits 8-14, the VOP3B carry-out field readlane does not have, sending
every readlane result to s0. Verified against raw gfx10 encodings and
LLVM's assembler tests (v_readlane_b32 s5, v1, s2 -> low byte 0x05).
* [VideoOut] Survive device loss and flip-order asserts without dying
Two ways a frame could take down the whole presenter:
- Device loss between any two Vulkan calls in a frame unwound the window
thread, and the Dispose-time fence check then threw again, masking the
original error. Catch the loss at the frame boundary, retire
presentations and guest submissions whose fences can never signal, and
keep the window loop pumping so the game (audio, logic) carries on.
- The ordered-flip capture invariant is violated ~100 times per run by
Demon's Souls (PPSA01342); on debug builds the Debug.Assert fail-fasts
the process with nothing in the log. Downgrade it to a once-per-version
warning until the capture/wait ordering is understood.

* [SourceGenerators] Add the SysAbi export generator and analyzers (phase 0)
New SharpEmu.SourceGenerators Roslyn component, complete and tested but
consumed by nothing yet — the emulator projects adopt it in the
following commits.
Ps5Nid ports the PS NID derivation (base64 of the byte-reversed first
eight SHA1 bytes of name + fixed suffix) from
scripts/generate_aerolib_binary.py to C#, so what has always been a
manual, out-of-band computation becomes a compile-time capability.
SysAbiExportGenerator emits a per-assembly SysAbiExportRegistry whose
CreateExports(Generation) reproduces ModuleManager's reflection scan
exactly — same generation inheritance and filtering, same method-name
fallback, same libKernel default — with attribute-omitted NIDs derived
algorithmically (equivalent to the runtime catalog lookup, which is
built from the same computation). Parameterless handlers are adapted to
the SysAbiFunction shape; invalid declarations are skipped here because
the analyzer rejects them as build errors, so nothing drops silently.
SysAbiExportAnalyzer turns the runtime failure modes into diagnostics:
SHEM001 duplicate NID (across declared and derived forms), SHEM002
malformed NID, SHEM003 uncallable handler signature, SHEM004 NID
contradicting its export name (the class of drift previously fixed by
hand), SHEM005 unresolvable export, SHEM006 export name unknown to
ps5_names.txt when the catalog is wired as an AdditionalFile, SHEM007
handler not reachable by generated code.
The self-contained test suite drives both in-process against the real
SharpEmu.HLE metadata: known catalog NID pairs pin the algorithm, the
generated registry must itself compile, and each diagnostic has a
triggering fixture. Fittingly, the NID pinning test caught a wrong
pair in its own first draft — the exact mistake SHEM004 exists to stop.
* [SourceGenerators] Adopt the generated export registry in the emulator (phase 1)
SharpEmu.Libs consumes the generator and analyzers, with
scripts/ps5_names.txt wired as the AdditionalFile catalog. The runtime
now registers exports from the compile-time SysAbiExportRegistry
instead of the boot-time reflection scan; RegisterFromAssembly is
retained solely as the arbiter for a parity test that pins the two
tables identical — same NIDs, names, libraries, targets, and handler
methods — across Gen4, Gen5, and combined registration.
First contact between the analyzer and all 715 existing exports
surfaced real drift the old offline checker structurally missed
(scripts/check_sysabi_aerolib.py skipped any NID absent from
aerolib.bin): three exports whose friendly names collide with real
catalog symbols of different NIDs, now suppressed at-site with reasons
pending AGC API confirmation, alongside the established synthetic
Unknown* labels for uncatalogued NIDs, which prompted a rule
refinement — SHEM004 only hard-errors when the export name is a real
catalog symbol, since synthetic labels cannot be validated by hashing
and the NID is authoritative for them. The two allowlisted mismatches
in the python checker no longer trigger anything, and the checker is
deleted: the analyzer subsumes it with the semantic model instead of
regex, and validates every declared pair rather than only
catalog-known NIDs.
* [SourceGenerators] Generate aerolib.bin at build time from ps5_names.txt
The runtime NID -> name catalog is derived data and no longer lives in
the repository: a Framework-only MSBuild task (GenerateAerolibBinaryTask,
sharing the same Ps5Nid implementation the analyzers use) builds it
into the intermediate directory from scripts/ps5_names.txt — now the
single source of truth — and SharpEmu.HLE embeds it from there. The
output is byte-identical to the previously committed binary, verified
with cmp against git history; a new test pins that the embedded catalog
loads and resolves a known symbol both directions.
scripts/generate_aerolib_binary.py is deleted (its algorithm lives in
Ps5Nid, its invocation in the build); the REUSE annotation for the
binary goes with it. MSBuild's Inputs/Outputs check means the ~154k NID
hashes only recompute when the names file actually changes. The task
implements ITask against Microsoft.Build.Framework directly, keeping
the vulnerable-flagged Utilities.Core package out and the analyzer
project's file-IO ban suppressed only inside the task itself.
* [SourceGenerators] Emit typed-signature register thunks (phase 2)
[SysAbiExport] handlers can now be written with real signatures — a
CpuContext followed by up to six int/uint/long/ulong parameters — and
the generator emits the SysV unmarshalling thunk, mapping parameters
positionally to RDI/RSI/RDX/RCX/R8/R9 with the same unchecked-cast
idiom hand-written handlers use. SHEM003 accepts the new shape and
rejects register overflow and non-register-representable types. Both
shapes coexist, so migration is per-handler; sceKernelPollSema,
sceKernelSignalSema, and sceKernelCancelSema migrate as the
demonstration (the last showing raw ulong guest-address passthrough).
The reflection scan cannot represent typed handlers, so it retires
here: RegisterFromAssembly, its signature validation, and
ResolveExportInfo are deleted, and the parity test that pinned the
generated registry to the scan is replaced by content-invariant tests
(duplicate-free, full 715-export surface, catalog identity). Deleting
the scan surfaced a phase-1 latent regression — the pre-JIT warm sweep
enumerated only reflection-scanned assemblies, so the generated
registration path warmed nothing and re-exposed the guest-thread
fail-fast risk; the warm set is now derived from the registered
handler delegates themselves.
* [SourceGenerators] Marshal guest strings declaratively with [GuestCString] (phase 3)
A string parameter on a typed [SysAbiExport] handler, annotated
[GuestCString(maxLength)], now makes the generated thunk read the
null-terminated UTF-8 string from the argument register's guest
address before the handler runs, returning
ORBIS_GEN2_ERROR_MEMORY_FAULT to the guest when the read fails —
the exact prologue nearly every string-taking handler writes by hand.
The attribute lives in SharpEmu.HLE next to SysAbiExportAttribute;
SHEM008 rejects misuse (non-string parameter, non-positive MaxLength)
while a bare string parameter stays a SHEM003 signature error.
_open, open, and sceKernelOpen migrate as the demonstration; they were
chosen because their hand-written prologue faulted on a null pointer
the same way the thunk does (handlers that return INVALID_ARGUMENT for
null pointers, like sceKernelCreateSema, keep the raw shape so guest-
visible semantics stay untouched).
* [SourceGenerators] Apply review findings across the branch
Behavior: the open/_open/sceKernelOpen [GuestCString] demo migration is
reverted — the local compat reader falls back to host memory for paths
in loader-mapped regions that ctx.Memory cannot see, so the generated
thunk would have turned recoverable reads into MEMORY_FAULT. The
marshalling infrastructure stays, proven by generator/analyzer tests;
production migration waits for a handler whose semantics the thunk
reproduces exactly. A comment on the handler records why.
Build robustness: the aerolib target is skipped for design-time builds
(the IDE resolves project references without compiling them, so on a
fresh clone the task assembly does not exist yet), and the task/names
paths are centralized in properties. The generator now emits no
registry for export-free assemblies, so referencing the analyzer can
never mint a colliding SharpEmu.Generated type.
Cleanup and perf: the pragma-suppression sites left mis-indented by the
phase-1 relocation are reformatted and the restores moved after the
method body; the dead ExportsForTesting hook and its InternalsVisibleTo
are deleted; the aerolib task reuses one SHA1 instance across ~150k
names; the analyzer caches the parsed catalog per file snapshot instead
of re-parsing 150k lines every compilation start, shares the attribute
name constant with the generator, and computes the catalog-membership
check once.
* [CI] Run the test suites in the build workflow
The workflow compiled the test projects (they are in SharpEmu.slnx) but
never executed them. A solution-level dotnet test now runs between
build and publish, so any test failure fails the build — including the
AerolibCatalogTests/SysAbiRegistryTests that guard the build-generated
aerolib.bin and the generated export registry. Generation failures of
aerolib.bin itself already fail the build step: the MSBuild task logs
an error event and returns false, and a missing task assembly or
missing embedded output are hard MSBuild errors. The NuGet cache key
now also tracks the test projects' lock files.
* [SourceGenerators] Address review feedback
Multi-diagnostic analyzer tests no longer assume a stable diagnostic
order (analyzer execution is concurrent), and the aerolib task logs
the full exception instead of only its message so build failures keep
the type and stack trace.
* [SourceGenerators] Address second review round
Symbol-name comparisons in the shape rules and analyzer now pin an
explicit SymbolDisplayFormat.FullyQualifiedFormat instead of relying on
the display-format default, and the aerolib task fails loudly on a
symbol name that would overflow the format's ushort length prefix
instead of silently truncating it, with null-safe output-directory
handling made explicit.
* [SourceGenerators] Embed aerolib.bin via a target so design-time builds never reference it
The static EmbeddedResource item referenced the generated file even in
design-time builds, where the generation target is skipped — on a fresh
clone the IDE would try to embed a file that never existed. The item is
now created inside an EmbedAerolibBinary target gated on
DesignTimeBuild, separate from the generation target so an up-to-date
skip of GenerateAerolibBinary cannot drop the item with the rest of its
body, and hooked before AssignTargetPaths since dynamic resource items
added later miss the resource pipeline.
Verified fresh build, incremental rebuild (embedded catalog test both
times), and a simulated design-time compile with no artifacts present.
* [SourceGenerators] Regenerate test lock file after rebase onto main
Rebase fallout: main's package graph shifted under #200, so the
SourceGenerators.Tests lock file is re-evaluated to keep --locked-mode
restore green at the branch tip.
* [Build] Drop NuGet lock files; rely on central package management
Central package management was already in effect (ManagePackageVersionsCentrally
with all versions in Directory.Packages.props and no inline PackageReference
versions), so the per-project packages.lock.json files and the lock-mode
workflow only added maintenance overhead. This removes all eleven lock files,
drops RestorePackagesWithLockFile so restore no longer regenerates them, and
takes --locked-mode off the CI restore steps (re-keying the NuGet cache on the
central props files). Package versions remain centrally pinned in
Directory.Packages.props.
* [Host] Abstract audio output behind IHostAudioOutput
Add IHostAudioOutput (opens streams, names the backend for diagnostics)
and IHostAudioStream (submit interleaved stereo 16-bit PCM, Dispose) to
the host seam, with the winmm waveOut implementation moving whole into
Host/Windows/WindowsWaveOutAudio — same device open, queueing,
32 KB backpressure wait, and buffer lifetime as WinMmAudioPort had. The
DllImports become source-generated LibraryImports in the move, matching
the other Windows backends.
The guest-format conversion (mono/stereo/7.1, s16/float32 -> stereo
PCM16) is platform policy, not device code, so it stays in Libs as
AudioPcmConversion; AudioOutOutput converts into a pooled buffer and
submits the result through the stream. Open failures still degrade to
the silent paced port with the same warning, and the port log line now
takes its backend name from the platform instead of a hardcoded string.
* [Host] Abstract pad and keyboard input behind IHostInput
Add IHostInput to the host seam: gamepad state snapshots, rumble /
trigger-rumble / lightbar sinks, and the keyboard-fallback queries
(window focus, key state). Gamepad state crosses the seam as the new
unmanaged HostGamepadState with HostGamepadButtons flags — named after
the PlayStation layout the guest API exposes but with the seam's own
values, so SCE_PAD_BUTTON bits never leak into host backends and the
per-frame poll can stackalloc its snapshot buffer.
The DualSense raw-HID reader, the XInput reader, and the Win32 HID
interop move whole into Host/Windows (report parsing, hot-plug loops,
rumble/lightbar output reports, and log strings unchanged), translating
to the neutral flags instead of ORBIS bits and converting their
DllImports to source-generated LibraryImports. WindowsHostInput
composes them plus the user32 keyboard queries; rumble still fans out
to both readers, trigger rumble stays XInput-only, lightbar stays
DualSense-only.
PadExports keeps all policy: the keyboard mapping (now via named
OrbisPadButton constants instead of raw hex), the controller-beats-
keyboard-past-deadzone merge, and the new host->ORBIS button
translation. The GUI's source-linked reader copies re-point to the
moved files (it still cannot reference SharpEmu.HLE wholesale), which
requires AllowUnsafeBlocks for the generated marshalling stubs; its
navigation code switches to the neutral flags.
* [Host] Move the timer-resolution request behind IHostThreading
IHostThreading gains RequestTimerResolution (idempotent, best-effort
~1 ms timed-wait granularity; a no-op wherever the platform default is
already fine). The winmm timeBeginPeriod call, its once-only latch, and
both warning strings move from the Libs-level HostTimerResolution
helper into WindowsHostThreading as a source-generated LibraryImport;
the vblank pump requests it through the platform instead.
HostSystemInfo in SharpEmu.Logging keeps its direct user32/kernel32
imports deliberately: Logging sits below HLE in the dependency chain so
it cannot see the host seam, every path is already OS-gated with
fallbacks, and it only runs once for the diagnostics banner.
Fills NID gaps hit by PS5 titles during boot, controller setup, and
rendering, and surfaces the common runtime switches in the GUI. All
exports are additive (no behavior change to existing exports) and free of
NID and export-name collisions with upstream.
New export libraries:
- libSceBluetoothHid: Init/RegisterDevice/RegisterCallback success stubs so
titles proceed past Bluetooth controller setup (opt-out via
SHARPEMU_BTHID_UNAVAILABLE=1).
- libSceNpCppWebApi: Common::initialize no-op success; UE5 online titles
abort PS5-component startup on a negative SCE error.
Additions to existing libraries:
- libScePad: scePadOpenExt (shared PadOpenCore, accepts special ports 1/2 and
the ScePadOpenExtParam pointer), scePadClose, scePadGetExtControllerInformation.
- libSceVideoOut: sceVideoOutConfigureOutput, sceVideoOutInitializeOutputOptions.
- libSceAgc: DCB builders sceAgcDcbSetIndexCount, sceAgcDcbJump, DcbSetPredication,
SetPacketPredication (emit valid skippable packets; full draw processing TODO).
- libSceAmpr: measure and write KernelEventQueueOnCompletion pair.
- libKernel: scePthreadGet/Setschedparam, sceKernelChmod (validate and accept;
POSIX permission bits have no host equivalent on Windows).
- libSceNetCtl: sceNetCtlRegisterCallbackV6 (delegates to the v4 callback).
- libSceMouse: sceMouseInit.
- libSceUserService: sceUserServiceGetAgeLevel (adult, skips parental gates).
GUI: new Options Environment tab exposing common SHARPEMU_* switches as
toggles (BTHID_UNAVAILABLE, DISABLE_IMPORT_LOOP_GUARD, VK_VALIDATION,
DUMP_SPIRV, LOG_DIRECT_MEMORY, LOG_NP). Persisted in gui-settings.json and
applied to the emulator process environment at launch; localized with
English fallback.
