Coverage: partial — complete physical I/O inventory, WPC-Security bindings, mechanism causality,
driver-variant boundary, and recreation behavior validated; wiring conflicted pending resolution of
the Fliptronic-cabinet-opto polarity conflict (switches 112/114) below, and one solenoid (34) has no
spatial evidence of any kind
Identity and evidence precedence
This is the Bally/Midway WPC-Security physical product released May 1994 (document 16-50031-101),
IPDB 2361. It covers the fourteen-driver wcs_* clone tree: wcs_l2 (parent, production LX-2),
wcs_l3c (2016 community "Competition MOD" firmware), wcs_la2/wcs_l1/wcs_la1 (earlier
language/region firmware), wcs_d2 ("LED Ghost Fix"), wcs_p2/wcs_p3 (prototypes),
wcs_p5/wcs_p6 ("LED Ghost Fix" prototype-lineage firmware), and wcs_f10/wcs_f50/wcs_f62/
wcs_f62b (FreeWPC community reimplementations). Every one of these is a game-ROM revision for the
identical physical machine; wcs.c's CORE_GAMEDEF/CORE_CLONEDEF share one static wcsGameData
struct across all fourteen.
Evidence precedence for this definition: the retained known-working VPW v1.5 script is runtime and
mechanism-causality ground truth; the Midway operations manual controls physical construction, part
numbers, wiring, polarity, quantities, and device presence; pinned PinMAME controls controller
generation, public address topology, mechanism-table position ranges, and display metadata; the
retained VPX geometry supplies normalized coordinates. The retained manual PDF carries a genuine but
unreliable OCR text layer on its multi-column parts lists, so every printed table used here was read
from rendered pages and transcribed into
external:pinmame-review-artifacts/world-cup-soccer/manual-transcription.md and its per-table
excerpts under evidence/excerpts/midway.world-cup-soccer.1994/.
GEN_WPCSECURITY (PINMAME_HARDWARE_GEN_WPCSECURITY = 0x20) with wpc_dispDMD. The controller
profile is pinmame.wpc-security, confirmed directly from wcs.c's own wcsGameData declaration
rather than assumed from the task brief. Page 3 of the manual independently confirms the platform in
its own text: "This game uses a new Security CPU Board that is not downward compatible...".
- Switches: dedicated coin-door 1-8, matrix 11-88 as drive column then return row, Fliptronic
111-118.
wcsGameData's inverted-switch mask {0x00,0x00,0x00,0x3f,0x1f,0x07,0x00,0x00,0x00, 0x00,0x00,0x00} inverts column 3 in full (31-36), column 4 rows 1-5 (41-45), and column 5 rows
1-3 (51-53) — fourteen addresses, exactly matching the printed matrix's own opto shading with
zero disagreement in the ordinary 8x8 matrix. The mask's twelfth element (index 11, the
Fliptronic column) is 0x00, so it does not cover the printed opto shading on Fliptronic
positions F2/F4 (public 112/114) — see the unresolved polarity conflict below.
- Solenoids: physical drivers 1-3, 5-6, 8-16 (all fitted, including 4 "Lock Release" and the
backbox-mounted 7 "Knocker" — this machine genuinely has a knocker coil, unlike some other WPC-era
games curated in this project); flashers/motors 17-28; Fliptronic upper-flipper circuits 33-35
repurposed for Magna Goalie/Loop Gate/Lock Magnet, 36 unfitted; WPC-Security has no integrated
LPDC board (unlike WPC-95/WPC-95DCS), so 37-44 are simply unused address space, not a duplicated
range; Fliptronic lower-flipper circuits 45-48; PinMAME state channels 29-32 (31 never populated
by this driver — see below); simulator-only 49 and reserved 50; a synthetic custom-solenoid mirror
at 51 despite
wcsGameData declaring custSol = 0 — see below.
- Lamps: 8x8 matrix 11-88, every address populated (no "Not Used" lamp positions, unlike the switch
matrix).
- GI: five strings on public addresses 0-4, three playfield (0, 1, 4) and two backbox insert-panel
(2, 3).
Two WPC-Security numbering facts must not be lost. First, this generation's public solenoid
addresses for the lower flippers (45-48) match the manual's own printed circuit numbers exactly —
there is no LPDC remap to alias, unlike WPC-95. Second, wcs.c computes a genuinely dispatched
custom-solenoid address (public 51, CORE_CUSTSOLNO(1)) even though wcsGameData declares
custSol = 0: core_getSol's solNo > 50 branch calls hw.getSol unconditionally, regardless of
the declared count, and wcs_getSol's own body returns core_getSol(sDivHold) || core_getSol(sRampDiv) — a live OR-combination readout of solenoids 16 and 8 with no physical
control line of its own. A recreation should bind one physical diverter mechanism to solenoids 8 and
16 and treat 51 as a derived diagnostic value, never a fourth device.
Ball path, trough, and shooter
World Cup Soccer has an automatic plunger (wcsSimData declares TRUE /* automatic plunger */
and there is no cabinet Launch Ball switch in the matrix, unlike several other games curated in this
project). Five balls rest on trough optos 31-35 (31 nearest the eject coil, 35 nearest the drain
entrance), all printed opto and normalized by PinMAME's inverted-switch mask. Solenoid 6 ejects the
ball on 31 toward the shooter lane; the retained script's SolTrough handler fires that kick and
pulses Trough Stack (36) in the same event. Pinned PinMAME's own internal ball-routing simulator
(wcs_stateDef, cited here only for switch/solenoid name cross-reference, never as physical
mechanism authority) places the "Trough stack" state immediately after the trough-eject state and
before the shooter-lane skill states, confirming switch 36 senses the ball's staging position toward
the shooter lane rather than a sixth ball resting in the trough — it has no dedicated VPX object of
any kind and is a documented projection onto the trough-eject Kicker.sw31 position. The ejected
ball rests on shooter-lane switch 38 (Ball Shooter); the retained script's cvpmImpulseP helper
auto-fires an impulse coil with no distinct public WPC-Security solenoid address of its own. Three
printed optos then trip in sequence down the skill-shot lane — Front (51), Center (52), Rear (53) —
built from the identical LED/phototransistor construction (A-16908/A-16909) as the Goal/Goalie
hole optos on the "10-Switch Opto Assembly" board.
A DC gearmotor (A-17741 Goalie Unit Assembly) drives the goalie figure one-directionally,
reversing at each end of travel (wcs_goalieMech: MECH_LINEAR|MECH_REVERSE|MECH_ONESOL,
WCS_GOALIETIME = 50, WCS_GOALIESLACK = 10). wcs_handleMech sets public switches 43 (Goalie Is
Left) and 44 (Goalie Is Right) directly from the motor's position counter (mech_getPos(0)), but
only while solenoid 21 is actively driving the motor (if ((mech & 0x01) && core_getSol (sGoalieMot))). Solenoid 21 is printed under the manual's "Flasher" type column with a "* +12VDC"
footnote rather than a normal flashlamp part number; this is a printed-table category quirk, not a
device conflict — wcs.c's own #define sGoalieMot 21 and the retained script's SolGoalie
handler (which plays fx_goaliedrive, a motor sound, not a flash effect) both independently confirm
the real function. The same pattern applies to solenoids 23/24 (the spinning-ball turntable motor,
below).
The retained VPW script does not read PinMAME's mechanism position at all: its own UpdateGoalie
routine runs an entirely independent sinusoidal position simulator (GoalieTheta incrementing every
frame) and asserts switches 43/44 directly from that simulation's own angle. Both switches are
therefore documented projections onto the goalie figure's own table object (Primitive BM_goalkeeper) rather than fixed playfield sensors; the retained script's own InitGoalie sets
BP_goalkeeper.x=376/.y=280, matching this primitive's stored position (374.4, 281.5) almost
exactly, which is what confirms the projection target rather than an arbitrary nearby object.
The goalie's own 35-segment target-wall ring (GoalieWalls, retained-table objects HitTarget. GT006 through GT040) surrounds the figure; GWalls_Hit fires the shared handler and pulses
Goalie Target (48, part A-17779) whenever a ball strikes whichever single segment is currently
collidable, the same "rotating figure with a segmented hit ring" pattern already documented
elsewhere in this project for a different WPC machine's rotating antagonist figure. Switch 48 is
likewise a documented projection, here onto the nearest fixed reference in the same script region
(Trigger.swPlunger, which shares switch 38's exact coordinates) rather than an invented
target-wall centroid.
The spinning soccer ball and the two magnets
A separate DC gearmotor turntable (A-17569 Motor Assembly with an A-16120 DC Motor Control
Assembly H-bridge driver board) spins a small soccer-ball toy under a plastic dome. wcs_ballMech
(MECH_LINEAR|MECH_CIRCLE|MECH_TWODIRSOL) models it as continuous two-direction rotation with no
discrete position switch; the retained script's cvpmTurnTable helper drives the visual spin
directly from solenoids 23 (clockwise) and 24 (counter-clockwise), both — like solenoid 21 above —
printed under the "Flasher" category with a "* +12VDC" footnote despite being motor drive lines.
Two independent playfield magnets complete the electromechanical inventory. Solenoid 33 (Magna
Goalie, 20-9247) energizes a magnet (cvpmMagnet on the retained table's MagnaGoalie trigger,
strength 16, GrabCenter = False) that deflects rather than captures the ball, helping the player
save a shot that would otherwise drain. Solenoid 35 (Lock Magnet, also 20-9247) energizes a second
magnet (LockMagnet trigger, strength 40, GrabCenter = True — genuinely halts the ball at the
magnet's center) that holds a locked ball for the multiball feature. Neither magnet has a dedicated
playfield switch; both are tracked purely in game software.
Fliptronic circuits repurposed for Magna Goalie, Loop Gate, and Lock Magnet
World Cup Soccer has no upper flippers (wcsGameData.hw.flippers = FLIP_SW(FLIP_L | FLIP_U) | FLIP_SOL(FLIP_L) — switches for all four flipper positions are read, but only the lower-flipper
solenoids are driven). The manual's own two tables on the same printed page (2-48) directly confirm
this by driver-transistor identity: solenoid 33 (Magna Goalie) shares Q2/J902-6/Yel-Vio with
the generic Flipper Circuits table's "Up Rt. Power" row; solenoid 34 (Loop Gate) shares Q7/
J902-4/Org-Vio with "Up Rt. Hold"; solenoid 35 (Lock Magnet) shares Q1/J902-3/Yel-Gry with
"Up Lt. Power". The fourth upper-flipper position, Up Lt. Hold (Q5), has no solenoid-table row at
all and is genuinely unfitted (public solenoid 36).
Solenoid 34 is the one address in this definition with no spatial evidence of any kind. The
manual's own two tables even disagree on its name — "Loop Gate" on the primary Solenoid/Flasher
Table (matching wcs.c's #define sLoopGate 34) versus "Lock Gate" on the Solenoid/Flasher
Locations parts list, for the identical coil part (A-14406) and assembly (A-17796, "Ball Gate
Actuator Assy." on the Lower Playfield Parts list). Unlike the ramp diverter and ramp lock post
below, an exhaustive search of the retained table's gameitems/ directory and script.vbs found no
Gate, Flipper, Wall, Trigger, or Light object and no script reference of any kind for this address.
Its playfield location is not asserted.
Ramp diverter, ramp lock post, and the Fliptronic column's opto polarity conflict
Solenoid 8 (Ramp Diverter) swings a diverter flap (A-18138) and solenoid 16 (Diverter Hold) holds
it in the diverted position; the retained script toggles two collision walls together. Left Ramp
Diverted (71) is the printed switch for this mechanism. Solenoid 4 (Lock Release, fully fitted —
verified at 600 dpi after an initial mis-transcription, see the manual-transcription review
artifact) retracts a post (A-18155) that otherwise holds a ball on the left ramp, sensed by Lock
Mech. Low (76) and Lock Mech. High (77) — a mechanical ramp lock distinct from the magnetic Lock
Magnet feature above.
Unresolved polarity conflict (conflict.flipper-cabinet-opto-not-normalized): the switch-matrix
page shades Fliptronic positions F2/F4 (public 112/114, the lower-right/lower-left flipper cabinet
buttons) exactly like the ordinary opto columns and prints them "Right/Left Flipper Opto". The
A-17316 board/assembly page independently confirms genuine opto-interrupter construction (item 1
03-9001 Interrupter Flip-Opto; item 2 A-16384 Flipper Opto Switch Assembly, built from an "Opto
Inter Lg. 10mA" component) — so the switch-locations parts list's plainer "Lower Right/Left Flipper
Cabinet" description is not a contradiction, just a less specific label for the identical hardware.
But wcsGameData's inverted-switch mask has twelve elements (columns 0-11, one per switch-matrix
column including the Fliptronic column at index 11); its twelfth element is 0x00, so unlike the
fourteen ordinary-matrix opto addresses, PinMAME does not normalize 112/114 despite the confirmed
physical construction. This keeps physical_wiring conflicted and the record partial; resolving
it needs a LibPinMAME harness trace of a legal wcs_l2 ROM observing the idle and active public
state of 112/114 as both lower flipper buttons are pressed and released.
Other toys and standard devices
A ball resting on opto 42 (Goal Popper Opto) is kicked by solenoid 1 to award a goal; Goal Trough
(41) senses a ball en route. A ball resting on opto 45 (TV Ball Popper) is kicked by solenoid 2.
Three ordinary VUK-style kickers cover the Upper/Left/Right Eject Holes (solenoids 5/15/14, switches
55/56/54) — wcs.c's own #define names (swLHole/swRHole) additionally tie 56/54 to the
printed "Left/Right Free Kick Hole" feature, and the internal simulator calls 55 the "Assist Hole".
Three A-9415-2 jet bumpers (solenoids 9/10/11) are sensed by switches 81/82/83; the retained
script's Bumper1_Hit/Bumper2_Hit/Bumper3_Hit handlers reveal that table object Bumper2 is the
printed "Left" jet bumper and Bumper1 is the printed "Upper" one — an object-index crossing
confirmed directly from the script rather than assumed from either label. Two slingshots (solenoids
12/13, score switches 84/85) each carry a direct-fire kick switch (SW-1A-114) and a separate
debounced score switch (SW-1A-120) wired to one public address. A ball in the left outlane trips
Kickback (86); when lit, solenoid 3 fires the kickback plunger, and Kickback Upper (26) senses the
return path while also doubling, per PinMAME's own internal naming, as the Header Lane sensor for
the same physical lane.
Fliptronic column: lower flippers
Two FL-11629 (Blue) flippers on Fliptronic circuits 111-114 (lower right/left, EOS then
button-opto). The ROM energizes the power winding on the cabinet button opto (112 right, 114 left),
then drops to the hold winding once the end-of-stroke leaf switch (111 right, 113 left) closes.
World Cup Soccer runs Const UseSolenoids = 2 (fast flips). Fliptronic positions 115-118 are
printed Not Used on both the switch matrix and the switch-locations parts list; there are no upper
flippers.
Lamps and general illumination
All 64 lamp-matrix addresses are populated; unlike the switch matrix, no lamp position is printed
Not Used. Four addresses drive two bulbs each — 46 "Ultra Spinner", 47 "Ultra Jets", 71 "Light
Jackpot", 78 "Ultra Ramps" — and unlike the brightness-doubled lamp pairs documented for some other
WPC-era games in this project, the manual prints a distinct assembly number for each bulb of
every pair, and the retained table's second Light object for each address sits at a materially
different playfield coordinate (not a co-located stack). Both bulbs of each pair are therefore
recorded as genuinely separate placements. Lamps 87 and 88 are the bulbs inside the illuminated
buy-in and start buttons; the retained table places both Light objects at normalized y > 1,
outside the playfield surface, independently confirming cabinet mounting.
General illumination splits three ways on the retained script's GIUpdate2 dispatch, which
implements only Case 0 (drives collection GILeft), Case 1 (GIRight), and Case 4 (GITop)
— with no Case 2 or Case 3 at all. This matches the manual's own wiring table exactly: GI
strings 0, 1, and 4 (printed 01, 02, 05) are the only three with a Playfield voltage/drive
connection printed; strings 2 and 3 ("Insert Background"/"Insert Title") are Backbox-only. Unlike
several other WPC-era games curated in this project, there is zero disagreement here between the
manual's physical wiring and the script's runtime implementation. Three GITop members (GI034,
GI035, GI036) sit at normalized y = -0.021148, just outside the playfield's 0..1 bounds near the top
rail; their y is clamped to the schema-valid boundary 0.000000 with the raw offset disclosed in the
spatial report, the same handling this project has already established for a small negative-offset
lamp row on a different WPC machine.
Author construction checklist
- Build the five-ball trough with the drain at Trough Ball 5, the automatic-impulse shooter lane,
the three-opto skill shot, both slingshots, three jet bumpers, the motorized goalie with its
35-segment target ring, the spinning-ball turntable, the two independent magnets (Magna Goalie
deflect-only, Lock Magnet capture), the mechanical ramp lock post, the ramp diverter, the Goal and
TV poppers, the three eject holes, and the kickback.
- Preserve opto polarity for 31-36, 41-45, and 51-53; do not invert what PinMAME already normalizes.
Switches 112/114 are also printed opto interrupters, but PinMAME does not normalize them — treat
their polarity as unresolved (
conflict.flipper-cabinet-opto-not-normalized) rather than assuming
either convention.
- Do not place solenoid 34 (Loop Gate/Lock Gate) anywhere on the playfield; no evidence supports a
coordinate.
- Bind every dedicated switch 1-8, every matrix position 11-88 including the printed Not Used
positions, Fliptronic 111-118 with 115-118 not installed, the eight CPU DIP bits, solenoids 1-51
(36 unfitted; 37-44 unpublished on this generation; 51 a diagnostic mirror only), lamps 11-88, GI
0-4, and the 128x32 DMD.
- Solenoids 21, 23, and 24 are motor drive lines despite being printed under the manual's "Flasher"
type column; do not model them as flash lamps.
