Build pinned libretro Snes9x 1.63 with this project's SDK and official metadata.
Convert final RGB565 frames to independent XRGB8888 storage for the existing
Vulkan upload path. Integrate staging, native imports and loader diagnostics.
Keep C++ destructor registration inside the unloadable core. Validate bounded
fini arrays before constructors and execute cleanup at last-reference close.
Test all 65536 colours through GPU upload, pitches/bounds/cached frames and
C++ destruction/reload/malformed finalizers. Existing core bytes are unchanged.
Verification: bash tools/verify.sh passed format/unit/build/integration/evidence
with 60 tests. bash tools/run-title.sh --no-build --core-test=snes9x --watch 180
passed loader/recovery and remained running until runner close. Owner: Works
flawlessly, answering colours/audio/input and menu/content-transition checks.
Zero Vulkan refusals, GPU API failures or kernel fatal-signal reports.
Evidence: evidence/snes9x-native/{capture,expectation,iterations,abi,build}.json,
loader/recovery reports and exact linked-driver hashes. Replay with
bash tools/verify.sh evidence. Frontend identity:
64bef2e7826e5a63a6644a933e24ef5403d28c754230c0038eb8a76b4baa1c53.
PS5_Vulkan was not modified; special-mode/save-state/performance coverage is
not implied by this ordinary-game acceptance.
Build pinned mGBA with this PS5 SDK, official metadata and both GB/GBA engines.
Support validated C initializer arrays, native directory/time imports and an
explicit config path. Map large title/core allocations so GBA archives load.
Correct mGBA callback colours and cached frame ownership, crop padded core
textures during presentation, and use the native shell exit after cleanup.
Verified: bash tools/verify.sh (format, unit, build, integration, evidence;
58 tests), then bash tools/run-title.sh --no-build --core-test=mgba --watch 180.
Owner confirms GB/GBC/GBA loading, correct colours/native Quit, and clean menu
and next game. Final capture has zero Vulkan refusals, GPU failure records or
kernel fatal-signal reports; normal frontend exit occurred before window end.
Evidence: evidence/mgba-native/{capture,expectation,iterations,build,abi}.json,
loader/recovery reports and exact linked-driver hashes. Replay with
bash tools/verify.sh evidence. Final build identity:
82024b89e74bbad4ad2ce2e2916d1a49baf26ac325fef20fc71a2c168b862337.
Patch count is deliberately 139: archive diagnostics, menu/cache ownership and
padded-source sampling edits. PS5_Vulkan was not modified. Saves/states,
long-run timing and a fresh FCEUmm/XMB transition matrix remain unverified.
Replace payload dlfcn hooks with a bounded ELF loader and explicit native
runtime bindings. Separate core RX/R/RW segments, reject unsupported ELF
features, and release failed loads. Guard failed menu selection before
frontend teardown and stop polling drivers after failed initialization.
Read core files through mapped buffers and bounded POSIX reads. Convert
libretro XRGB8888 frames to matching RGBA8 staging/sampled textures so real
content uses the verified Vulkan copy path rather than the RGB565 compute
branch. Keep video_ps5 selectable and preserve frontend/audio/error logs.
Validation: tools/verify.sh passed all five gates (52 tests). Console command:
tools/run-title.sh --no-build --core-test --watch 180, with manual core/game
selection. Eight ELF load/unload cycles and live-menu failure recovery passed;
owner confirmed flawless gameplay. Zero GPU refusals/API failure records and
kernel fatal signals across captured launches. Return-to-menu shortcut and
repeated game unload/reload remain unverified; owner closed/reopened the app.
Evidence: evidence/native-core-loading/{capture,expectation,loader,recovery,
abi,iterations}.json; replay with tools/verify.sh evidence. Accepted title
identity 9b287ca7e0d4a04721c68d30fb88b678a62cc568c1f2d44b75716b464c21b6d5.
No PS5_Vulkan edits by this task; its independently advancing checkout is
not used as a substitute for the accepted title's archive-bound identity.
