10 ROM sets resolve to this machine. Clones share the definition unless a hardware difference is listed.

Controller platform
pinmame.wpc-95

PinMAME already reports logical active state. Do not invert again in the table — normally-closed is a physical fact recorded per switch, not a runtime transform.

Coverage

Partial

Real evidence exists, but authoring requirements are still missing or in conflict. Verify before shipping a table.

Completion19%

Progress is derived from the fixed author-readiness requirements. It helps rank unfinished work, but only a 100% author-ready definition passes the publication gate.

Recreation notes

Working knowledge that has no schema field yet — edition differences, tuning values, pitfalls.

Coverage: partial - machine identity plus candidate-only I/O attachments. Playfield devices, wiring, mechanisms, and behavior are evidenced only as unverified candidates.

This record was promoted from the generated catalog stub stub.pinmame.wd_12 by the catalog-wide identity pass of 2026-08-29. The promotion resolves machine identity and carries the catalog's residual driver grouping over unchanged, the platform and device attachments below were added by the 2026-08-29/30 candidate passes and assert nothing beyond candidate provenance. Every requirement in the definition's coverage.missing is genuinely outstanding.

Identity

  • PinMAME catalog: root driver wd_12, description "WHO Dunnit (1.2)", manufacturer "Bally", catalog year "1995".
  • OPDB record G50kj-MDqpv (IPDB 3685) names this machine "WHO dunnit" (Bally, manufacture date 1995-01-09); the resolved identity rests on the agreement of the PinMAME catalog and this reviewed mapping.
  • The definition's driver list is exactly the clone tree PinMAME declares under wd_12; whether every listed driver really runs on this physical machine is unverified.

Drivers this record holds

  • wd_03r (1995, Bally, clone of wd_12).
  • wd_048r (1995, Bally, clone of wd_12).
  • wd_10f (1995, Bally, clone of wd_12).
  • wd_10g (1995, Bally, clone of wd_12).
  • wd_10r (1995, Bally, clone of wd_12).
  • wd_11 (1995, Bally, clone of wd_12).
  • wd_12 (1995, Bally).
  • wd_12g (1995, Bally, clone of wd_12).
  • wd_12gp (2020, Bally, clone of wd_12).
  • wd_12p (2020, Bally, clone of wd_12).

PinMAME source contract (candidate)

  • The pinned PinMAME source declares wd_12 at src/wpc/sims/wpc/prelim/wd.c:327 with machine module wpc_m95DCSS; the definition declares controller platform pinmame.wpc-95 from it.
  • The driver source's named switch/solenoid symbols are carried as 27 candidate devices in the definition.

What a curator must establish next

Full input, output, and display enumeration with semantic names; physical wiring and polarity; mechanism inventory and behavior; variant differences across the clone tree; recreation knowledge from a manual, schematic, or known-working table; runtime provenance; and a normalized spatial placement for every physical device. No manual, schematic, or runtime-harness evidence is retained for this machine yet; the candidate sections above are the only retained I/O evidence so far.

Evidence

Every claim above traces to one of these. When they disagree: a known-working VPX script wins on controller addresses and causality, the manual wins on wiring and construction, pinned PinMAME wins on emulator routing and display layout.
