Recreation notes

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

Coverage
partial - source-derived recreation knowledge requiring validation

Overview

Legacy evidence identifies this candidate as Williams (1982). The information below is preserved for recreation work but is not automatically treated as validated physical-machine fact.

Playfield devices

Switch, lamp/GI, and controlled-device candidates are in the adjacent machine definition. Source-specific implementation notes are retained below.

Custom mechanisms

No custom mechanism conclusion has been validated. Manuals, schematics, PinMAME source, and gameplay evidence still need to be checked.

Ball-state transitions

Ball paths, trough ordering, locks, kickouts, and causal transitions have not yet been normalized. Relevant source notes follow under Evidence notes.

Controller interactions

Controller callbacks and bindings are candidate evidence only until reconciled against PinMAME and physical documentation.

Service and setup information

Unknown; locate operator/service documentation.

Timing and tuning observations

Source timing values may describe a particular VPX implementation rather than physical hardware and require review.

Recreation guidance

Do not treat this partial definition as a complete authoring specification. Resolve every coverage requirement and conflict before promotion.

  • games/defender.json#/coils/28._inferred_type: drop_target_reset
  • games/defender.json#/coils/28._note: Multiplexed via sol 11. Drops all center targets (sw33-35)
  • games/defender.json#/coils/29._note: SolCallback blanked for fast-flip workaround. Flipper driven directly via KeyDown/KeyUp calling SolRFlipper. Framework constant from S7.VBS.
  • games/defender.json#/coils/30._note: SolCallback blanked for fast-flip workaround. Flipper driven directly via KeyDown/KeyUp calling SolLFlipper. Also drives LeftFlipper1 (upper left). Framework constant from S7.VBS.
  • games/defender.json#/lamps/0._note: Solenoid-driven via SolPFGI (coil 14). Lampz.state(0) set by coil callback, not lamp matrix. Controls GI light collection.
  • games/defender.json#/lamps/1._note: Status lamp — Controller.Lamp(1) used in UpdateMultipleLamps (VR: l1, Desktop: ShootAgainReel)

  • games/defender.json#/lamps/9._note: Lampz.MassAssign(9) with Light9h highlight prim
  • games/defender.json#/lamps/39._note: Also has Light39f flasher variant

  • games/defender.json#/lamps/56._note: Also has Light56f flasher variant
  • games/defender.json#/lamps/63._note: Solenoid-driven via SolCenterFlasher (coil 21). Lampz.state(100) set by coil callback. Mapped to flash1/flash2/flash3/flash4/flashh VPX objects.
  • games/defender.json#/_source/confidence_notes: High confidence on switches/coils from SolCallback and sw*_Hit handlers. Lamp assignments from InitLampsNF Lampz.MassAssign and Controller.Lamp comments in UpdateMultipleLamps/UpdateDTLamps. Uses S7.VBS (Williams System 7). Solenoid 11 is multiplexed per System 7 convention — coils 33-42 are multiplexed via sol 11 (VPM 1.52+ handles automatically, older versions offset by +32). Lamp 0 is GI (solenoid-driven via SolPFGI on coil 14). Lamp 100 is center flasher (solenoid-driven via SolCenterFlasher on coil 21). Tilt switch is swTilt from S7.VBS framework (platform-defined, typically switch 2 on System 7). Flipper solenoid callbacks are blanked for fast-flip workaround — flippers are driven directly in KeyDown/KeyUp subs.

Unresolved questions

  • Is the I/O enumeration complete for every supported physical/controller variant?
  • Which inferred VPX behaviors reflect real hardware, and which are table-script conveniences?
  • Are all mechanism home states, sensors, motion constraints, and ball interactions documented?

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.
