- [widescreen] nw_flat_backdrop: in the native-wide mirror only, stretch untextured flat primitives across the wide output (flat-colour sky/water backdrops). Canonical 4:3 framebuffer stays byte-for-byte untouched. - [widescreen] nw_phase_backdrop: stretch textured prims emitted before the frame first shaded 3D primitive (authored 2D backdrop phase), isolating the sky from the textured 3D foreground. Both runtime-only, off by default, title-opted (draw ordering is title-specific). - [video] fmv_skip_no_xa_hold (4..3600 vblanks): presentation-side fast-forward latch after the last silent MDEC decode, so auto-skip covers a preloaded logo authored post-decode wait (Whoopee Camp logo). Guest timeline unchanged; default stays the generic 4-vblank hysteresis. - ws_dbg_stretch correlation modes 7 (all prims) / 8 (all flat prims). - fmv_state: JSON-escape config_path + report fmv_skip_no_xa_hold. Validated on Tomba 2: Release build, unattended first-attract captures at 4:3 / 16:9 / 21:9, zero unknown dispatches. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Internal dev-logs & design notes
These are the working design documents and burn-down logs the project was built from. They are historical/working notes, not contributor onboarding docs — they capture decisions, phased plans, and deep subsystem investigations in the order they happened, and some sections are superseded by later ones.
If you're new here, start with the top-level README.md,
then docs/ARCHITECTURE.md,
docs/EXECUTION_MODEL.md,
docs/BUILDING.md, and
CONTRIBUTING.md. Come here when you need the why
behind a specific subsystem.
Plans & roadmap
PLAN.md— the original phased build plan (P1–P6).FAITHFUL_TIMING_PLAN.md— the authoritative cycle-accuracy north-star plan and status log.FIRST_MILESTONE.md— the first-boot milestone gate.STUBS_TO_FIX.md— hardware-stub burn-down (pre-game gate).
Cycle accuracy & timing
PRECISE_IRQ_SLICE.md— exact-instruction IRQ delivery.CYCLE_MODEL_BEETLE.md— the Beetle-derived cycle model.ACCURACY_BURNDOWN.md— full accuracy burn-down across all axes (semantics, cycle, IRQ, MMIO, peripherals, determinism).COSIM_ORACLE.md— the first-divergence co-sim oracle.
BIOS / scheduler
HLE_SCHEDULER_CARVEOUT_PLAN.md— the cooperative-thread scheduler HLE carve-out.WEDGE_load4_shell_rootcause.md— a specific boot-shell wedge root-cause writeup.
Renderer / widescreen
GL_RENDERER_HANDOFF.md— OpenGL renderer design.NATIVE_WIDE_PLAN.md— native-wide 16:9 (GTE FOV) plan.BACKDROP_PRELOAD.md— widescreen backdrop preload.
Overlay cache internals
SLJIT_PERSIST_CACHE.md— persisted overlay-shard cache design.
