Coverage

Partial

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

Completion13%

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.eatpm_l4 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 eatpm_l4, description "Elvira and the Party Monsters (LA-4)", manufacturer "Bally", catalog year "1989".
  • OPDB record Grlxp-MVKBW (IPDB 782) names this machine "Elvira and the Party Monsters" (Bally, manufacture date 1989-01-01); 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 eatpm_l4; whether every listed driver really runs on this physical machine is unverified.

Drivers this record holds

  • eatpm_3g (1989, Bally, clone of eatpm_l4).
  • eatpm_4g (1989, Bally, clone of eatpm_l4).
  • eatpm_4u (1989, Bally, clone of eatpm_l4).
  • eatpm_f1 (1989, Bally, clone of eatpm_l4).
  • eatpm_l1 (1989, Bally, clone of eatpm_l4).
  • eatpm_l2 (1989, Bally, clone of eatpm_l4).
  • eatpm_l4 (1989, Bally).
  • eatpm_p7 (1989, Bally, clone of eatpm_l4).

PinMAME source contract (candidate)

  • The pinned PinMAME source declares eatpm_l4 at src/wpc/sims/s11/prelim/eatpm.c:281 with machine module elvira; no platform is declared (no reviewed profile covers that module yet).
  • The driver source's named switch/solenoid symbols are carried as 58 candidate devices in the definition.

What a curator must establish next

Controller platform from the pinned PinMAME driver source; 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.

Something wrong or missing?

This definition still has 14 unmet requirements, listed under Coverage above. Fixes belong in the definition itself — editing on GitHub forks it for you and opens the pull request.

Cite a source for anything you change — a manual page, a line in a working VPX script, PinMAME source, or a reading from the machine's own service menu. Claims without provenance cannot be validated.
