📄 Description

Summary

Every provider refuses PlayStation 2 Emotion Engine executables: MIPS ELF32
files that declare EF_MIPS_MACH_5900 fail with "Machine-specific MIPS
variants … need a separately supported processor profile". This adds a bounded
PS2 profile to the existing Ghidra provider, following the PSP precedent. REA
pins the language of the caller-installed
ghidra-emotionengine-reloaded
extension and fingerprints the extension, but never installs it.

Related: #5240 takes a similar approach for legacy ee-gcc retail executables.
This PR is kept separate so each can be reviewed on its own. The differences
are listed under "Change and scope".

Problem and expected behavior

rea function <PS2 ELF> <name> --provider ghidra fails with
architecture_unsupported. With the extension installed and its r5900.sla
precompiled, CLI and MCP:

  • resolve lane ps2-ee-elf32-exec-r5900-v1;
  • import with ElfLoader / r5900:LE:32:default / default;
  • serve the ordinary inventory, instruction, reference, string and function
    operations.

Without the extension they fail with PS2_EXTENSION_UNAVAILABLE and an
installation remedy.

Change and scope

  • GhidraProcessorExtension.ts: the PSP extension inspection, generalized and
    parameterized by id, label, profile, failure code, required files and an
    optional installed-state check. PSP exports, messages and identity are
    unchanged.

  • GhidraPs2Profile.ts / GhidraPs2Extension.ts: admission and the extension
    spec. Admitted targets run on Linux x64 hosts and are little-endian ELF32
    ET_EXEC, R5900 machine, MIPS III, with only NOREORDER/CPIC hints, and
    either:

    • n32 with the R5900 ABI flags record that PS2SDK emits (ps2dev v2.0.0), or
    • EABI64 (legacy-SDK shape) with that record, or with the record absent
      after every declaration table was inspected.

    Everything else is refused: o32/EABI32/mixed ABIs, PIC/ASE/FP64/NAN2008,
    unknown records, incomplete or carved inspections, and caller language
    overrides.

  • Precompiled SLEIGH requirement. Release archives ship only sources, and
    Ghidra 12.1 SleighLanguage recompiles a missing, wrong-format or stale
    .sla inside the installation. REA refuses an r5900.sla without the
    format-4 header or older than its .slaspec/.sinc sources. Analysis
    therefore never modifies the installation, and the fingerprint stays stable.

  • Wiring:

    • processor dispatcher and analysis profile;
    • provider host check;
    • provider client: expected language at handshake, Evidence limitations;
    • launcher: re-inspection before launch.

    The PS2 limitations are kept short because every response repeats them.

  • tests/conformance/ps2/ fixtures, --ps2 / --ps2-missing-extension modes
    for scripts/verify-real-ghidra-mips.mjs, and docs/ghidra-ps2.md.

Not included: IRX/ERX, relocatable or shared images, ISO and other
containers, runtime overlays, VU microprograms, emulation, non-Linux-x64
hosts, and static recompilation.

Differences from #5240:

  1. This PR admits current PS2SDK n32 homebrew. #5240 refuses it because it
    carries an ABI flags record.
  2. It requires a precompiled, fresh r5900.sla instead of letting Ghidra
    write into the installation.
  3. It uses reproducible source-owned fixtures with a real CLI/MCP verifier.

#5240 also admits an unspecified-ABI header. This PR does not, because no
producer evidence for that shape was available.

Contract and boundary impact

  • Semantic owner and earliest changed stage: Ghidra target admission
    (ghidraProcessorUnsupportedReason), then analysis-profile resolution.
  • Contribution scope fit and linked maintainer decision: static decompilation
    of a new processor family through an existing provider. No maintainer
    decision yet; feedback welcome.
  • CLI and MCP/tool-catalog contract: unchanged, apart from newly admitted
    targets and the new failure code PS2_EXTENSION_UNAVAILABLE.
  • Provider, bridge, target-format, or platform compatibility: Ghidra only,
    Linux x64 only; bridge unchanged. Generic MIPS, PSP and IOP (R3000)
    headers keep their lanes or refusals.
  • Evidence, artifact, provenance, or reconstruction contract:
    • new profile parameters: mips_support_lane, ps2_abi_declaration,
      ps2_extension, and the pinned loader, language and compiler;
    • five PS2 limitations, plus one for a recordless EABI64 header.
  • Target selection, authority, upstream behavior, and cleanup details: not
    applicable (static import; ephemeral project as before).
  • Generated metadata, package, or installation impact: none.

Expected effects:

  • Read existing files or captured data.
  • Launch or attach to a process.
  • Inject instrumentation or run scripts/code. Note: for .mdebug targets,
    the caller-installed extension's STABS analyzer runs its bundled
    stdump, as installed Ghidra code. This is documented and can be
    disabled with REA_GHIDRA_DISABLED_ANALYZERS.
  • Change process memory, registers, files, or configuration.
  • Contact network services.
  • Recover protected code or work around protections.
  • Documentation or usability only; no target interaction.
  • Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

  • Tests added or updated:
    • tests/boundary/filesystem/ghidraPs2Extension.test.ts;
    • tests/conformance/ghidra/ps2-checks.test.ts;
    • tests/conformance/ghidra/mips-checks.mjs, which now accepts a null ABI
      record.
  • Base reproduction or other evidence: on the base revision, both PS2
    fixtures are refused as machine-specific MIPS variants.
  • Real provider, both fixtures (PS2SDK n32 e312d08b…, legacy EABI64
    dcc503da…):
    • observed r5900:LE:32:default / default;
    • exact bytes and mnemonics of li, paddw, pcpyld, three-operand
      mult and vadd.xyzw;
    • caller, call-site xref, global xref, and the marker string together with
      its EE RAM mirrors;
    • snapshot reopen, A-B-A target switch and CLI Evidence;
    • process lineage verified with no descendants.
  • Caller-owned retail executables (outside the suite; no game data in the
    repository). This was 11 EE executables from 7 discs: 6 USA titles from
    2003–2006 and one modified disc.
    • All 11 declare the legacy-SDK EABI64 shape (0x20924000/0x20924001)
      with no record and are admitted.
    • All 7 boot executables analyze as r5900:LE:32:default and their entry
      functions decompile. They have 4,183–28,022 procedures each.
    • One title built with Metrowerks CodeWarrior has all 4,183 function names
      recovered from its symbol table; its runtime overlay sections stay outside
      the image, as documented.
    • Two tasks hit REA's general 10 MiB MCP response budget rather than a
      profile limit: a 28k-function string list, and the load image of the
      CodeWarrior title with 56,477 relocations. A separate issue will propose
      smaller responses.
    • For one title, God Hand, the boot ELF SHA-256 equals the public
      god-hand-decomp record. With that project's function list as
      REA_GHIDRA_SEED_FILE seeds:
      • all 10,122 decomp function starts are found, and 2,922/2,922 names sit
        at the exact address;
      • call sites match raw jal decoding (902/902 on the most-called
        function);
      • the callees of 19 functions with matched C equal that C (85/85).
  • Remaining proof gaps:
    • carved PS2 images and non-EABI64 retail header shapes not observed;
    • only Ghidra 12.1.3 with extension v2.1.38;
    • no CI lane with the extension;
    • reopening a snapshot re-runs auto-analysis (about 150 s for a 2.8 MB
      .text).

For evidence-bearing changes:

  • Observed, derived, and inferred claims remain distinguishable.
  • Artifact identity, source provenance, and failed attempts remain preserved.
  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

All on this branch, rebased onto main 47353e494; the branch also merges cleanly with b7f8bbb49, whose 5 newer commits touch no PS2, Ghidra, ELF or MIPS files. Environment: WSL2 Ubuntu
24.04 (Linux x64), Node 24.18, Temurin JDK 21, Ghidra 12.1.3.

  • npm ci && npm run build:cached — passed.
  • npm run check — passed (lint 0 errors, module boundaries, architecture guards).
  • npm run test:focused -- <34 Ghidra extension/conformance/provider test files> — 945 passed, 1 skipped.
  • node scripts/verify-real-ghidra-mips.mjs --ps2 — passed (256 s).
  • node scripts/verify-real-ghidra-mips.mjs --ps2-missing-extension — passed.
  • node scripts/verify-real-ghidra-mips.mjs --psp (ghidra-allegrex v21.4, PSPDEV v20261001) — passed (186 s); --psp-missing-extension — passed.
  • npm run docs:check / npm run verify:test-discovery — passed (re-run for the docs update).
  • Generic MIPS verifier (Clang/LLD 18.1.3), on the pre-rebase branch with the EE
    and Allegrex extensions installed — passed for 6 fixtures. The generic
    MIPS32r2 control is still observed as MIPS:LE:32:default, and the
    IOP-shaped R3000 ELF is still refused.
  • Full npm run check:pr on the pre-rebase branch: 18 tests in 10 files
    failed. All of them are outside Ghidra/MIPS/PSP/PS2 and fail identically, or
    flakily, on unmodified main in this environment (Kuna, WindowsHandleClose,
    ciStaticArtifacts, runtime URL mapping, mutation workflow, symlink race).

Compatibility, safety, and release

  • Breaking changes or migration steps: none.
  • Real Hopper/Ghidra, browser, or OS coverage: Ghidra 12.1.3, Temurin JDK 21,
    Linux x64 (WSL2). Windows and macOS hosts are refused for this profile.
  • Package or release metadata impact: none.
  • Security, privacy, process, or containment review: same model as PSP. The
    extension is identified by content, not signed or sandboxed. The .sla
    freshness rule keeps analysis from writing into the installation.

All of them are outside Ghidra/MIPS/PSP/PS2 and fail identically, or flakily, on unmodified `main` in this environment (Kuna, WindowsHandleClose, ciStaticArtifacts, runtime URL mapping, mutation workflow, symlink race). ## Compatibility, safety, and release - Breaking changes or migration steps: none. - Real Hopper/Ghidra, browser, or OS coverage: Ghidra 12.1.3, Temurin JDK 21, Linux x64 (WSL2). Windows and macOS hosts are refused for this profile. - Package or release metadata impact: none. - Security, privacy, process, or containment review: same model as PSP. The extension is identified by content, not signed or sandboxed. The `.sla` freshness rule keeps analysis from writing into the installation. ## Author readiness Human owner: <!-- @GitHub-handle --> - [ ] I reviewed the final diff and relevant existing code, understand the change and its edge cases, and take responsibility for the complete PR, including AI-assisted work. - [ ] I checked the evidence above, confirmed it supports the current change, and recorded meaningful validation gaps. - [ ] I declare this PR ready for initial maintainer review. ## Before merge - [ ] This PR addresses a concrete problem or an agreed enhancement. - [ ] Material scope and authority questions are resolved, and any required maintainer scope decision covers the final diff. - [ ] The PR has one focused outcome and the title follows `type(scope): outcome`. - [ ] Related issue is linked, or the reason for not linking one is stated above. - [ ] Tests cover changed observable behavior and meaningful failure paths. - [ ] Owning docs, contracts, and generated metadata are updated where needed. - [ ] User-visible CLI/MCP changes include representative output. - [ ] I checked the final diff for secrets, unrelated cleanup, and unsupported claims. --- <sub>🔄 This issue represents a GitHub Pull Request.
