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.
Handle project-relative file URIs through the guest app0 mount, including unambiguous case-insensitive lookup for case-sensitive hosts.
Reject host paths, traversal underflow, malformed or remote URIs, and symlink/reparse escapes; cover accepted app0 forms and sandbox boundaries with nonparallel tests.
The Gen5 caller supplies a one-byte flag. Preserve pointer and memory-fault behavior while writing only that byte, and cover a seeded guest-memory boundary that rejects the former four-byte write.
V_READLANE uses the gfx10 VOP3A vdst byte even though its result is scalar. Decode bits 0-7 and cover the public LLVM s5 and s101 encodings so the VOP3B sdst field cannot be confused with this opcode again.
* [AGC] Decode VOP3P and emit packed f16 arithmetic (first slice)
On gfx10 the VOP3P family lives under its own 0b110011000 prefix (word0
top byte 0xCC), which the major-opcode switch currently routes to the
SMEM branch, so packed instructions were decoded as scalar memory ops
and emitted as silent no-ops. Intercept the exact 9-bit prefix ahead of
the switch, decode the five packed-f16 arithmetic opcodes with their
op_sel/op_sel_hi/neg_lo/neg_hi/clamp modifiers, and emit them as
UnpackHalf2x16 -> component-wise f32 vec2 ops -> PackHalf2x16 so no
Float16 capability is needed.
Bit layout and opcode numbers pinned to LLVM MC test encodings
(vop3p.s, gfx10_vop3p_literalv216.txt) and VOP3PInstructions.td.
Unsupported modifiers, packed constants and out-of-scope packed opcodes
fail with a clear error instead of emitting wrong results.

* [AGC] Make packed f16 exact and drop v_pk_fma_f16 (review response)
Address the FP16 correctness review on the VOP3P slice.
Replace GLSL UnpackHalf2x16/PackHalf2x16 with explicit integer f16<->f32
conversions (EmitHalfToFloat/EmitFloatToHalf): exact widening with subnormal
normalisation, and narrowing with round-to-nearest-even, overflow-to-Inf and
NaN/Inf handling. Their subnormal and rounding behaviour no longer depends on
implementation-defined float-controls modes.
With exact conversions, v_pk_add_f16 and v_pk_mul_f16 are bit-exact to a true
f16 op (f32 result rounds losslessly to f16; a f16 product fits in f32). Emit
v_pk_min_f16/v_pk_max_f16 as fminnum_like/fmaxnum_like (NaN operand returns the
other; ordered numeric compare) instead of GLSL FMin/FMax.
v_pk_fma_f16 now fails emission loudly: a fused f16 FMA rounds once, an f32
multiply-add then pack double-rounds (fma(0x4100,0x7522,0x04EA) is 0x7A6B fused
vs 0x7A6A via f32). Exact fused emulation is a planned follow-up slice.
ShaderDump gains an Expect model (Translates/DecodeFails/EmitFails) and packed
regressions: arith, non-default modifiers, and loud-failure pins for the fma
case above and for clamp.

* [VideoOut] Prefer real integrated GPUs over software rasterizers (#325)
Penalize only AMD integrated GPUs (the #97 vkCreateGraphicsPipelines
crash) instead of all integrated devices, so Intel/Apple/Qualcomm iGPUs
outrank Cpu-type software rasterizers (Mesa lavapipe). Hoist
ScorePhysicalDevice to the outer class and add unit tests for the
ordering.

* [VideoOut] Scope AMD iGPU penalty to Windows via a penalty helper
Extract ComputeDevicePenalty (the value subtracted from a device's base
score) and gate the #97 AMD-integrated penalty on Windows only. Mesa RADV
on Linux (e.g. the Steam Deck's AMD APU) is a different, working driver
and should keep its full integrated score. Add a Steam Deck test case and
drop inline comments.

* [VideoOut] Move device-scoring helpers out of the const block
Relocate ScorePhysicalDevice and ComputeDevicePenalty below the leading
const cluster instead of splitting it, and trim the vendor-ID reference
comment to adapters an x86-64 host can realistically enumerate.

Reimplement the five synthetic regressions from codefusion-repo/sharpemu#3 and #8 on sharpemu/sharpemu main befd20f415.
Keep the contributor-owned harness and corpus discussed in sharpemu/sharpemu#36 out of scope; use only a focused local recording memory fixture.

Changes MapPixelFormatToGuestTextureFormat to default to format 56 (8-bit
RGBA) when the game uses a pixel format not yet in the known list, with a
stderr warning that reports the exact format value for project issue reports.
Previously, unknown formats returned 0, which caused RegisterKnownDisplayBuffer
to skip registration entirely. The GPU backend then couldn't find the buffer
during flip, producing vk.flip_capture_failed, and some games later hit a
Debug.Assert in ExecuteOrderedGuestFlipWait.
The fallback produces wrong colors for the affected games but lets them render
and display output, which is strictly better than a black screen or access
violation crash. The pixel format is printed to stderr so developers can
identify it and add proper support.

* [SaveData] Implement save data memory2 exports
Astro Bot calls sceSaveDataSetupSaveDataMemory2 during boot and asserts
and null-writes when it fails, so the missing import surfaces as a
named crash. This implements setup plus the companion get, set, and
sync operations that make it useful. The store is one zero-filled file
per user and title at sce_sdmemory/memory.dat under the save root,
readiness is the backing file's existence, and get, set, and sync
return MEMORY_NOT_READY before setup. Struct offsets follow the
publicly documented homebrew savedata headers.
* [SaveData] Write setup result before mutating the memory backing file
Astro Bot asserts and null-writes when a subsystem init call fails, so
each missing import surfaces as a named crash. This stubs the blockers
observed during bring-up: content export init, eight font calls, and
pad tilt correction. sceFontGetHorizontalLayout writes the same
invented geometry as sceFontGetRenderCharGlyphMetrics and the rest
report success. Together with save data memory2 these take the title
to its splash image and font glyph rendering path.
* Implement DescribeAddressForDiagnostics method
Added a method to describe the state of a memory address for diagnostics.
* core: enrich allocation failure exception with host region diagnostic
* 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
Adds decode and SPIR-V translation for the missing MUBUF, MIMG and DS
atomic instructions in the Gen5 shader translator, generalizing the
existing BufferAtomicAdd path. Covers swap, cmpswap, add, sub,
smin/smax, umin/umax, and/or/xor, inc and dec, plus the DS RTN
variants. Image atomics go through OpImageTexelPointer on the storage
image binding.
Notable: DS_CMPST operand order (DATA0 = comparator, DATA1 = new
value) is reversed relative to buffer/image cmpswap, which a dedicated
test locks in. ATOMIC_INC/DEC are approximated with
OpAtomicIIncrement/IDecrement, exact for the common 0xFFFFFFFF clamp.
Verified with 9 new synthetic decoder and end-to-end SPIR-V tests
(part of the #36 test corpus effort); full suite passes 35/35.
