Adapt PR #14's biased 32.32 triangle edge DDA and half-open bottom/right coverage across the software raster paths, with a focused pure edge-math regression test. Source: https://github.com/mstan/psxrecomp/pull/14 Source-commit: https://github.com/mstan/psxrecomp/commit/91a654f61dff18806f3eea43f72a30cb34430695 Co-authored-by: Kareem Olim <kareemolim@gmail.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capture decisions, phased plans, and deep subsystem investigations in the order they happened, and some sections are superseded by later ones.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.
