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.algar_l1 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 algar_l1, description "Algar (L-1)", manufacturer "Williams", catalog year "1980".
  • OPDB record G5nQQ-MLbbp (IPDB 42) names this machine "Algar" (Williams, manufacture date 1980-01-09); 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 algar_l1; whether every listed driver really runs on this physical machine is unverified.

Drivers this record holds

  • algar_l1 (1980, Williams).
  • algar_l1ff (1980, Williams, clone of algar_l1).

VPX script candidates (candidate)

  • 1 retained community table script(s) declare this machine's driver; their extracted switch/lamp/solenoid/GI candidates are carried as 36 candidate devices. When curator work weighs sources, a retained script outranks emulator-derived candidates for runtime semantics, but every device here is still a candidate until a known-working table is verified against this exact physical machine.

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.

Pinball memory maps

External source LGPL-3.0-only1 map

RAM layouts published by an independent project and mirrored here at a pinned commit. They are not part of this machine’s definition: nothing below was used as evidence for the definition, and none of it counts towards coverage. Check claims against the upstream project.

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 Missing data below. 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.

Missing data

What this game definition still needs to reach 100% and become author-ready.

  • ROM compatibility

    Verify which PinMAME drivers and firmware variants belong to this physical machine.

  • Controller hardware

    Identify the controller platform and validate its public address and routing rules.

  • Complete input inventory

    Account for every switch, service input and diagnostic address, including unused positions.

  • Input functions

    Validate which physical sensor or cabinet control each input represents and when it activates.

  • Complete output inventory

    Account for every coil, motor, lamp, flasher and general-illumination circuit, including unused addresses.

  • Output functions

    Validate the physical device, function and fitted quantity behind each output binding.

  • Displays

    Verify every display, its layout and its controller bindings.

  • Mechanism inventory

    Document every mechanism, its moving parts, actuators, sensors and connections.

  • Mechanism behavior

    Validate mechanism operation, ball paths, home positions, startup and reset behavior.

  • Switch construction and polarity

    Verify normally open or closed contacts and how PinMAME delivers their active states.

  • Edition and firmware differences

    Document supported hardware and firmware differences without combining incompatible editions.

  • Recreation knowledge

    Complete the source-backed behavior and assembly notes needed to recreate the machine.

  • Evidence and sources

    Back the remaining claims with attributable sources, exact locators, retained excerpts and verified hashes.

  • Physical device locations

    Establish validated playfield locations for every physical sensor, actuator and light emitter, including bulb counts and justified projections.
