The repository root carried seven markdown files that were not onboarding
material, plus two that had been superseded by the code they described. This
sorts them: reader-facing docs to docs/, working notes to docs/internal/, and
the two superseded ones merged into the docs that replaced them.
Moved to docs/: WIDESCREEN.md, ENHANCEMENTS.md, TCP_COMMANDS.md
Moved to docs/internal/: PRINCIPLES.md, ISSUES.md, DEBUG.md, GTE_LM_FIX.md,
and from docs/: bios-hardening.md, overlay-status.md,
overlay-plan.md, overlay-recompilation-design.md,
overlay-discovery.md, TOMBA2_EXC_CONSULT_RESPONSE.md,
CASE_A_AOT_GAP.md, audit_inventory.md
Moved to docs/internal/upstream/: UPSTREAM_2026-08-20.md
The root keeps only what belongs there: README.md, CONTRIBUTING.md, LICENSE,
CLAUDE.md, THIRD_PARTY_ATTRIBUTION.md, RELEASE_NOTES.md, the dotfiles and
psxrecomp_cli.py.
MERGES
SPLITGEN_MIGRATION.md folded into docs/BUILDING.md as "Split generated C". Its
migration instructions were stale in a way that mattered: it told every game
repo to hand-edit its CMakeLists and add a file(GLOB ...) over
<serial>_full*.c, but runtime/runtime.cmake now does that itself. GEN_FULL_GLOB
is a multi-value argument of psxrecomp_add_game_runtime(); the loop at
runtime.cmake:1985 makes each pattern absolute against CMAKE_CURRENT_SOURCE_DIR,
expands it with file(GLOB), and concatenates the hits into
GAME_GENERATED_FULL_C. So a title names the pattern and gets however many shards
a regeneration produced. The rewritten section describes that, the two-step
fallback when the globs match nothing (GEN_FULL_FALLBACK, else <serial>_full.c
derived from the dispatch marker by substituting _dispatch.c), and the one
caveat the code actually has: that file(GLOB) is plain, not CONFIGURE_DEPENDS,
so a regeneration which changes the shard COUNT needs a re-configure to be seen.
psxrecomp-toml-readme.md folded into docs/GAME_PROJECT_SETUP.md as "EXE-only
autofill (psxrecomp-toml)", placed after "Disc autofill (probe_disc.py)" and
before "Project Studio" so the two autofill paths sit together. Its documented
flags were checked against the usage text in recompiler/src/main_toml.cpp:28-42
and against the argument parser at :150-165 -- all seven options match with no
drift, so the flag list is reproduced as-is. Added a pointer that probe_disc.py
is preferable when a cue exists, since that tool does the same EXE-header work
plus disc identity and netplay gates.
FUNCTIONAL FIXES
tools/gen_tcp_commands.py wrote to REPO/"TCP_COMMANDS.md". After the move that
path does not exist, so the generator would have created a new stray root file
and --check would have failed against it forever. Retargeted to
REPO/"docs"/"TCP_COMMANDS.md", along with the seven docstring and message
strings that name the path.
Running it surfaced two further problems, both fixed here:
* The doc was genuinely stale -- pre-existing drift, not introduced by this
commit (the moved file is byte-identical to origin/master, and no
debug-server command table is touched here). Four commands registered since
the last regeneration were missing from the index -- cdrom_timing_dump,
savestate_status, ws_ui_groups, xprobe_watch -- and scanline had gained a
backend. Regenerated: 307 -> 311 commands, and the change is confined to the
AUTOGEN block (the hand-written head and tail are byte-identical to master).
tools/gen_tcp_commands.py --check now exits 0.
* DOC.write_text() has no newline argument, so Python translated every newline
to os.linesep. On Windows that rewrote all 585 lines of the file to CRLF and
turned a four-line index update into a whole-file diff -- measured: 589 CRLF
/ 0 LF after a run, against 0 CRLF / 585 LF in the repo. Now written through
an explicit newline="" handle, verified to leave the file at 0 CRLF.
runtime/include/debug_server.h:9 and runtime/src/debug_server.c:8 cited "TCP.md
and DEBUG.md". TCP.md has never existed in this repo under that name; both now
name docs/TCP_COMMANDS.md and docs/internal/DEBUG.md.
LINK AND REFERENCE FIXES
Every inbound reference to a moved file was located by grepping each basename
across the whole tracked tree, not just the markdown. Markdown hrefs in
README.md, CONTRIBUTING.md, docs/ARCHITECTURE.md, docs/COMPILING_OVERLAYS.md,
docs/AOT_OVERLAY_PLAN.md, docs/RELOCATION_MANIFEST_FORMAT.md,
docs/config_schema.md, docs/OVERLAY_XREF.md, docs/TCP_COMMANDS.md and several
docs/internal/ files now point at the new locations; where two files became
siblings under docs/internal/ the path was shortened rather than lengthened
(bios-hardening.md's reference to overlay-discovery.md, for instance).
docs/COMPILING_OVERLAYS.md's "in this folder" phrasing was wrong once two of the
three files it listed moved, so it now names internal/ explicitly.
24 source-comment mentions of ENHANCEMENTS.md sections G1.x across 19 files
(recompiler, runtime, cmake) were retargeted to docs/ENHANCEMENTS.md with the
section numbers untouched. docs/SHADOW_ENHANCEMENTS.md is a DIFFERENT file and
was deliberately excluded.
20 rationale strings citing docs/CASE_A_AOT_GAP.md across the four
recompiler/seeds/*.json files were updated. Done as a byte-level substring
replacement rather than a JSON round-trip: two of those files are stored with
CRLF endings and two with LF, and re-serializing them reformatted 5,700 lines.
The byte-level version changes exactly 20 lines and each file still parses.
References that look similar but point elsewhere were deliberately left alone,
and are worth naming so a future pass does not "fix" them:
* "recomp-template PRINCIPLES.md" / "NES recomp template PRINCIPLES.md" in
CLAUDE.md:43, docs/SHADOW_ENHANCEMENTS.md:28,
docs/internal/HLE_SCHEDULER_CARVEOUT_PLAN.md:5,
runtime/src/debug_server.c:4934 and tools/parity_diff.py:8 are a different
repository's file. Only the five that mean this repo's PRINCIPLES.md were
updated.
* Every remaining bare ISSUES.md mention is a GAME repo's tracker
(MegaManX6Recomp 2/7/8/9, TombaRecomp 6), not this repo's.
* docs/disc-speed.md:4,54,56 and docs/internal/bios-hardening.md:5 name
overlay-discovery as a BRANCH, not a file, so no path applies.
INDEXES
README.md's "New here?" table gains rows for docs/WIDESCREEN.md,
docs/ENHANCEMENTS.md and docs/TCP_COMMANDS.md. docs/internal/README.md gains
sections indexing all fourteen documents that moved in, plus an "Upstream
contributor reviews" section describing upstream/ and the new sweep file, plus a
"Removed" bullet for CYCLE_TIMING_ARCH.md (deleted in the previous commit)
pointing at FAITHFUL_TIMING_PLAN.md, CYCLE_MODEL_BEETLE.md and
PRECISE_IRQ_SLICE.md -- following the SLJIT_PERSIST_CACHE.md precedent already
in that file.
docs/ENHANCEMENTS.md:7 claimed framework bugs live in "game repos' ISSUES.md
until a framework tracker exists". A framework tracker does exist; it now says
so and names the Beads epic.
VERIFICATION
A link checker was written to scan every tracked *.md for relative links,
resolving each against the tree being scanned. Baseline at origin/master: 129
files, 137 relative links, 3 broken. After both commits: 127 files, 159 relative
links, 3 broken -- the SAME three, all pre-existing and untouched here:
docs/DATA_SHARDS.md -> INSTANT_LOADS_PARKED.md (never existed)
docs/DATA_SHARDS.md -> INSTANT_LOADS_SPIKE2.md (never existed)
docs/NETPLAY.md -> ../lib/recomp-net/README.md (inside a submodule)
Zero new broken links. The checker's own coverage was checked against a raw grep
for markdown link openers: the 3-link difference is C++ lambdas inside code
blocks, correctly not treated as links.
Also verified: py_compile over all 113 tracked tools/*.py plus psxrecomp_cli.py;
all four seed JSONs still parse; the test-registration guard still reports 123
test files all registered; recompiler/tests/test_coverage_vault.py still passes;
and no file in this commit had its line endings flipped (checked mechanically
across all 50 modified files, after two files were caught and redone).

The sljit Tier-2 in-process JIT was replaced by the tcc tier in c2a3f6ad
(2026-06-25) and removed outright in 5b7e69b4 (2026-07-15). That removal
reworded the C-level comments but touched no markdown, so the prose still
described sljit as a live, default-on backend.
Backends today are static -> gcc -> tcc: gcc is the development default when
it is on PATH, tcc is the toolchain-free path for players. Both are external
compilers invoked as a subprocess that produce a DLL; neither is an in-process
JIT. docs/ARCHITECTURE.md, docs/BUILDING.md, docs/EXECUTION_MODEL.md,
docs/COMPILING_OVERLAYS.md and README.md already said this correctly and are
unchanged here.
- THIRD_PARTY_ATTRIBUTION.md: the sljit entry claimed code vendored at
lib/sljit/ and compiled into the runtime. That directory does not exist.
Replaced with a TinyCC entry, which was missing entirely despite tcc being
the compiler intended to reach end users.
- docs/internal/SLJIT_PERSIST_CACHE.md: deleted. It documented the persisted
shard cache of a subsystem that no longer exists, as "implemented" and
"default-on". docs/internal/README.md updated to point at the current model
instead of a dead link.
- docs/ASYNC_OVERLAY_COMPILE.md: superseded-in-part header. Deliberately NOT
rewritten sljit->tcc: the passages about serializing .sljit blobs,
overlay_sljit_deserialize and an in-memory JIT registry describe a mechanism
tcc never used, so renaming it would trade one false claim for another. The
async worker/file-handoff design and the CPS work remain accurate.
- docs/OVERLAY_CACHE_V2.md: sljit dropped from the dispatch priority chain.
- ISSUES.md: Issue #7 closed as superseded — the backend it reported against
was deleted rather than fixed.
- docs/internal/COSIM_ORACLE.md: sljit_helpers left CPUState with the tier.
- Dated session logs (RECURSION_BUG.md 25.5, BACKDROP_PRELOAD.md,
ecosystem-watch.md) keep their narrative and get a pointer to the removal.
One thing this does not fix: docs assert the tcc toolchain is "downloaded at
release-packaging time and bundled beside the game exe". runtime/src/main.cpp
does look for <exe_dir>/overlay_toolchain/, but no script in this repository
creates it. The attribution entry now states only what the code does and notes
that if packaging supplies the bundle, it happens outside this repo and must
carry the TinyCC notice. Flagged rather than papered over.

Master fixed the embed_spirv.py concurrency race independently and better
(tempfile.TemporaryDirectory cleans up on early-return error paths too), so the
rebase conflict was resolved in master's favour and our mkdtemp version
removed. This branch stays SPU-only.
Records the trap that invalidated the first Tomba 2 measurement: game.toml's
overlay_autocompile_cmd names a recompiler path, and when it is absent
autocompile fails every attempt, no shard is ever built, and the runtime
silently interprets everything. Tomba 2 expects a worktree-relative path the
documented build recipe does not produce; MMX6 hardcodes an absolute path into
the main repo that works only by luck of local layout. Check autocompile_status
before trusting any perf number from a fresh worktree.

The first FMV A/B was run on a fresh worktree whose overlay shard cache was
cold AND whose autocompile could never work: game.toml points at
psxrecomp-v4/recompiler/build-t2/psxrecomp-game.exe while the documented build
recipe builds the recompiler at build-recompiler/ in the worktree root, so it
failed 8/8 with WinError 2 and the runtime silently ran interpreted
(dispatch_native = 0). The '40 fps / ~19 underruns per second' attributed to
master in the previous commit was that broken setup, not master.
Re-measured against the fully warm cache with the pre-SPU exe as a control in
the same worktree: interp_share 0.7813 vs 0.7775, exc_share 0.2386 vs 0.2381,
39.1 vs 38.0-38.4 fps. Identical within noise, so the DSP work is free.
Separately characterises the real pre-existing defect: the FMV is 96% native by
dispatch count but 78% interpreted by wall clock with 24% in exception
handling, even warm.

Measured, not asserted:
- BIOS LLE boot proves the reverb engine runs and rings down after the dry
signal stops; noise LFSR observed shifting with correct parity feedback.
- Tomba 2 intro FMV A/B against the exact parent commit shows the added
per-frame DSP work is performance-neutral (min p50 40.0 vs 40.3 fps) and
does not starve the CD bus or the host sink. The FMV's 40 fps and its
~19/s host underruns are PRE-EXISTING on master.
- Records all ten places the documentation ran out as an oracle-comparison
work list, and the two merge prerequisites (rebase onto moved master; bump
recomp-ui to 99558ee or no title compiles).

Closes the four gaps named in issue #103 and lands the separable, verified
parts of PR #102. See docs/internal/SPU_FIDELITY_103.md for the per-piece
disposition and the oracle-verification queue.
SPU DSP (issue #103), clean-room from hardware documentation:
- Reverb: the documented 22050 Hz engine — vLIN/vRIN input, same-side and
crossed different-side IIR reflections, 4-tap comb early echo, both
all-pass filters, vLOUT/vROUT output, and the work-area address advance.
Gated on SPUCNT bit 7 for WRITES only; reads, IRQ checks, address advance
and output always run, as on hardware. Addressing is confined to
[mBASE, 0x80000). Per-voice sends from EON, CD send from SPUCNT bits 0+2.
- Noise: 16-bit LFSR with the documented parity feedback, clocked at the
SPUCNT bits 8-13 rate; NON voices substitute it for their ADPCM sample.
- Volume sweeps: all 24 voice L/R plus main L/R. Bit 15 selects sweep vs
direct; sweep is a live envelope on the same rate machinery as ADSR, and a
guest read of a sweeping register returns the live level.
- Capture buffers: CD L/R and voice 1/3 output written to SPU RAM, so a game
that parks the IRQ address there still gets its interrupt.
- SPU IRQ (I_STAT bit 9): checked at every SPU RAM access class — FIFO, DMA
both directions, ADPCM block fetch, capture writes, reverb work-area
accesses — gated on SPUCNT bit 6, mirrored in SPUSTAT bit 6, acked by
clearing SPUCNT bit 6.
The CD-only fast path in spu_render was removed rather than extended: the
SPU now has per-frame work that must run in every path, and an FMV (XA audio
with zero active voices) is exactly the CD-with-reverb case.
This is a clean-room implementation from the psx-spx/nocash register map and
documented algorithm. Beetle's source was deliberately not consulted: it is
GPL-2.0-or-later and this project is PolyForm Noncommercial. PR #16 was
parked for exactly that reason and PR #13's reverb was separately wrong (it
gated on bit 15 of dAPF1, an address offset, instead of SPUCNT bit 7). The
one place this knowingly deviates from hardware is the 22.05 -> 44.1 kHz
reconstruction filter, which the documentation does not specify; it is
isolated in a single function and flagged for oracle comparison.
CAUSE.IP2 (from PR #102):
IP2 is combinational on R3000A — it mirrors the interrupt line and falls the
instant the guest acks I_STAT or masks the source. It was being OR'd in at
delivery and never cleared, in TWO places (the compiled path and
psx_interpreter.c, the latter missed by PR #102), leaving a phantom pending
interrupt that can spin a kernel dispatcher looping on CAUSE.IP & SR.IM.
psx_irq_refresh_cause_ip2() is now the sole writer of bit 10, refreshed at
raise, I_STAT ack, I_MASK write, HLE context restore and power-on. Verified
against the Beetle oracle's irq.cpp/cpu.cpp rather than asserted, and
covered by test_cause_ip2_combinational.
Mid-dispatch audio pump (from PR #102), with a fix: routed through a gate
that mirrors sdl_audio_update's mute/sink decision. Pumping unconditionally
from the VBlank edge, as submitted, would have pushed real audio during every
turbo-load hard mute and defeated the freeze-in-place mute model.
SPU RAM DMA readback (from PR #102): DMA4 in the SPU->RAM direction wrote
literal zeros; SPU RAM is readable memory and titles carry state through it
across an Exec boundary.
Also fixes an unrelated build race found on the way: tools/embed_spirv.py
wrote its intermediate SPIR-V to <source>.spv, so the two runtime targets
that embed the same shaders raced on one path and one deleted the file the
other was reading.

Makes the parked projection/perspective work reachable and gets it into the
renderers people actually use. Addresses issue #92 (PGXP-style geometry and
texture correction).
The GTE side cache, SWC2 RAM provenance, GP0 triangle preparation and the
software-renderer consumption path already landed in 2ceaf5a ("park projection
and perspective correction", from kem0x PR #14), but were unreachable: the
generic setters gte_geometry_correction_set() / gpu_texture_correction_set()
had no production caller, and the corrected vertices went straight to
sw_set_precise_triangle(), bypassing the renderer vtable — while the default
renderer is OpenGL.
This adds:
- [video] geometry_correction and [video] perspective_texturing, in game.toml
and settings.toml, both defaulting false. Independent knobs; the launcher
seed marks them present so a save round-trips a hand-edited key instead of
dropping it. Startup names the active pair, and notes when geometry
correction is on below supersampling 2 (where it cannot be seen).
- gr_set_precise_triangle() / gr_set_perspective_triangle() on the
GpuRenderBackend vtable, so gpu.c hands the correction to whichever backend
is live rather than to the software rasterizer directly. NULL entries no-op.
- OpenGL and Vulkan consumption. Positions are already float end-to-end, so
sub-pixel vertices drop in; the readback dirty rect widens by one pixel to
cover them. Perspective UVs use a per-vertex a_q weight and clip coordinates
pre-multiplied by w = 1/q, letting the hardware's own perspective divide
interpolate a smooth UV varying beside the affine noperspective one. a_q == 0
— the default, and what every prim gets with the feature off — makes w
exactly 1.0 and selects the affine varying, so the faithful path is the
pre-feature pipeline unchanged.
The PS1-visible GTE SXY FIFO stays integer either way: guest-side screen-bounds
culling and SXY readback are untouched, and this remains visual-only.
Also fixes a pre-existing concurrent-build race found while validating: every
runtime target runs embed_spirv.py over the same shaders, and each wrote
"<shader>.spv" next to the source, so under -j N one process deleted the file
another had just written (FileNotFoundError on a shader that compiled fine).
The intermediates now go to a per-invocation temp dir.
Parked-work provenance retained; see ENHANCEMENTS.md G1.

Extract the useful diagnostic from PR #13 into an opt-in, title-agnostic boot
write-range trace with TCP-queryable context.

`bios_hle` (default on) is the player-facing "skip the BIOS and go
straight to the game" flag, and it did nothing under the bundled
OpenBIOS: choosing OpenBIOS sat the player in the boot animation while
the identical build on retail SCPH-1001 went straight to the game.
Root cause was ordering, not policy. The tier has two axes with
different per-image requirements:
* boot-skip needs only `shell_entry_phys`, works under pure LLE
(nothing is synthesized — the shell call just returns
immediately), so any image exporting it can skip
* kernel-call needs `deliver_event_ret`, the kernel's own
DeliverEvent `$ra`, or a delivered callback returns to
the wrong PC
main.cpp correctly refused the call axis on an image without
`deliver_event_ret` by assigning `bios_hle = false` — and then derived
`boot_skip` from that already-mutated flag. OpenBIOS omits
`deliver_event_ret` (B0 semantics unvalidated) but DOES export
`shell_entry_phys`, so an available skip was cancelled by an unrelated
refusal, and one flag meant two things depending on a BIOS detail no
player can see.
Both axes are now decided by one pure, dependency-free function,
`psx_bios_hle_plan()` (runtime/src/bios_hle_plan.c): the boot decision
reads the REQUESTED `bios_hle`, each axis is gated on only the anchor it
needs, and refusals are reported at startup instead of downgrading
silently. `psx_bios_hle_configure()` clamps `boot_skip` to
`shell_entry_phys != 0` as a backstop so the banner and `hle_dump`
cannot overstate what can fire. The main.cpp local is renamed
`bios_hle_requested` and is no longer written back from the plan — the
`session_reboot` path re-enters that block, so folding a refusal into
the request would have made a netplay rematch differ from first launch.
Also in this pass:
* A BIOS profile's `[runtime]` block was parsed into
`BiosConfig::runtime` and read by NOTHING, and bios/OpenBIOS.toml
carried an inert `bios_hle = false` there that read as the reason HLE
was off on OpenBIOS. It was not. `load_bios_config` now REJECTS
`[runtime]` in a BIOS profile: a profile states facts about an image,
never preferences.
* `psx_icache_fastpath_test` had been unbuildable ("redefinition of
`psx_advance_cycles`" — the test's counting stub vs the header's
`static inline`), which blocked every runtime test registered after
it. It now builds with `PSX_OVERLAY_DLL_BUILD=1`, the seam
psx_cycles.h already provides for a TU supplying its own advance.
Tests: new `bios_hle_plan_test` pins the matrix, including a 64-case
sweep asserting the boot decision is independent of
`deliver_event_ret` and the call decision independent of
`shell_entry_phys`. Runtime ctest 15/15, recompiler ctest 30/30.
Validated on Ape Escape (SCUS-94423) built against this framework with
both backends linked, headless, all four cases:
OpenBIOS default bios_boot=skip to game; route=2 fire at vec 0x30000

documents); in-game on screen
retail default bios_boot=skip to game; route=2 at vec 0x30000
ra=0xBFC0702C; in-game on screen; differs only in
bios_backend=HLE (LLE fallback)
PSX_BIOS_HLE=0 bios_boot=real intro; ring empty (no hook)
KEEP_INTRO=1 bios_boot=real intro; ring empty
