Replace the global bonus approximation with the original per-player secondary
score and multiplier. Lock holes now accumulate 10k, 20k, 40k, 80k, and 160k;
the fifth transfer applies the current multiplier, clears the secondary score,
increments that multiplier, and grants the recovered extra-ball count.
Route effects 1 through 5 into the same secondary score and make effect 6
transfer its displayed multiplied value before clearing it. Render that value
on the table and stop adding an unrelated global bonus during drain, preserving
secondary progress across balls as the original player state does.

Replace the float nudge direction, cooldown, and decaying meter with the
scan-code-specific Win16 behavior. Left Shift and keypad 3 now use the original
random directional impulse, while Space uses the reconstructed random horizontal
and vertical formulas with scalar 15 and wrapping millipixel velocities.
Track the original 16-bit tilt counter: each nudge adds 25, compares against
30 + Random(10), and the selected detail timer decrements a nonzero counter once
per callback. Allow the same input while a ball waits in the launcher, retain
bonus state when tilt latches, clear flippers immediately, and keep Right Shift
only as a documented modern alias for keypad 3.

Replace the Xorshift state with the reconstructed Borland Win16 generator,
including its wrapping linear update and high-word Random(n) mapping. Route
launcher clamp variation, effect selection, and claw terminal choices through
one shared stream so seeded event order follows the executable.
Use the same stream for the recovered magnetic-field response. Fields now scale
horizontal speed by 0.9 and choose the upward impulse from
-3800 * (1 - Random * 0.3) instead of assigning a fixed -3000 velocity. Adjust
deterministic scenario expectations where the original stream permits a second
natural claw capture or does not force one during a particular autoplay seed.

The rewrite assigned one WAV resource to each logical event, which could not
represent the original call-site behavior. It played reserved WAV 2022 for
media awards, omitted multi-sound bank sequences, and used the wrong cues for
captures, bumpers, targets, nudges, and tilt.
Emit explicit sound-resource events at the reconstructed C control-flow sites
so logical rendering events no longer imply audio. Move media threshold
advancement into score addition, retain one threshold transition per call, and
use wrapping 32-bit score arithmetic. Restore the ninth-diamond 24,464-point
completion, the subsequent double-score activation, and later 100,000-point
secondary-score awards.

Replace the partial mechanics transcriptions with a separate, readable C11
reconstruction of the complete Win16 image while preserving the original raw
Ghidra export as immutable evidence. Cover all ordinary and overlapping entry
points, Borland runtime behavior, Win16 imports, segmented data, callbacks,
resources, indirect control flow, physics, rendering, persistence, and
startup/shutdown lifecycles.
Add deterministic extraction and audit tooling plus address-linked ledgers for
functions, imports, DGROUP ranges and objects, relocations, resources, and
callbacks. The final gate records zero raw, partial, restored, unknown,
blocked, or unclassified required units. Keep the semantic-fidelity boundary
explicit: the portable C is not claimed to reproduce a byte-identical Borland
NE build.
Add strict focused harnesses for every reconstructed C unit, exact resource
round-trip checks, and a 16-bit Borland Real48 reference probe. No Rust source
or Cargo metadata is changed in this phase.

Map detail levels 1-5 to the recovered 50, 40, 30, 20, and 10 ms callback

Implement the flagged object-84 selector and initially inactive type-4 object
149. Choose a different effect from 1-6, render the enabled target from its

Interpret the claw's 3800-unit release scalar per 10 ms physics substep rather
than per 30 ms animation frame. This removes a factor-of-three slowdown from all
four random terminals and restores terminal 18 to raw `(0,1000)`.
Add exact assertions for positions and raw velocities of terminals 1, 6, 7,

Represent press and release as distinct deferred flipper edges. Keep upward
position/velocity transfer unchanged, and apply the position-preserving
return-stroke velocity recovered from a live ball at `(125,390)`, mirrored for

Add a standalone, syntax-checked C transcription of the recovered ball state,
10 ms substep, launcher repeat/release arithmetic, one-sided type-2 response,
swept type-1 response, and previous-position contact application. Link the

Replace the inferred eight-sector wheel and central lock rectangle with the six

double each successive bonus from 10,000 through 160,000, transfer the complete
310,000 on the fifth, and return a launcher ball without consuming one.
Restore object 148 as the wheel-reset target and clear all filled-hole state on

Move claw contact and all eleven initially active type-4 circle records onto a
swept millipixel sensor test with per-object enter latching. Preserve the exact
left-bank and top-gate coordinates, radii, and scores from the initialized

Add a reproducible dump of all 175 initialized collision and rule records from

This extends the static function ledger with the runtime-built data table needed

Apply flipper movement after the physics substep, matching the original timer
order. Replace the weak generic tangent kick with the recovered swept-body
position transfer and pre-clamp velocity curve fitted from three live left-edge
probes, then mirror that local transform for the right flipper.
The x=125 probe now reaches `(138.182,355)` with raw velocity within two units

Replace each invented centerline capsule with the original pair of moving line
records and moving tip circle. Use the exact asymmetric raised coordinates read
from live objects 66-68 and 81-83, while preserving their recovered type-1 and
type-2 fixed-point response coefficients in normal object traversal.
Remove the last generic segment overlap solver. Edge-time ball transfer remains

kick derived from the 3800-unit speed scalar.
Unify line and circle traversal in original object-id order and remove the old
floating passive-circle and bumper impulses. Add exact tests for live object 155
and bumper 51 transitions, and keep moving flippers as the explicit remaining
collision approximation.

Repeated SIGSTOP-based injection can suspend Wine while its Win16 mutex is held

Replace the guessed variable-rate floating integration with the original 10 ms
millipixel step, 15-unit gravity, and 3800-unit speed limit. Restore every
registered type-2 Real48 response pair, one-sided start-to-end orientation, and
the original normal/tangent velocity transform validated against live shooter
wall traces.
Restore repeat-driven plunger charging and its release-time randomized clamp.
The shooter route now follows table orientation instead of coordinate-specific
gate exceptions. Remove the synthetic ball-search impulse so future stuck balls
remain visible reconstruction failures, and include collision ids in deterministic

Expose the original detail-derived integration count, active-ball count,
gravity, maximum speed, and movement flags in live traces. Allow probes to
force one physics substep so a single collision response can be observed
without the default three-step timer batch obscuring intermediate state.
Record the dynamically verified type-2 rail response: resolve velocity in the
registered line's normal/tangent basis, apply the two original Real48
coefficients, then advance from the previous position using that response.

The tracer could only rediscover the game object while all original position

Add an atomic live-state injector for the traceable Wine process. It updates
all recovered global and object copies of ball position and velocity while the
process is stopped, clears pending impulses, and re-enables normal collision
processing before resuming the unmodified executable.
This makes individual walls, circles, gates, and mechanisms reachable without
relying on random gameplay. Document the first controlled claw probe, including

WineDbg changes the Win16 exception path and cannot capture continuous game
state reliably. Add a Linux-only launcher that opts the normally running Wine
process into same-user tracing without modifying TDKPIN.EXE, plus a sampler
that locates the loaded DGROUP and game object from recovered signatures.
The CSV trace exposes original millipixel positions, predicted positions,
velocities, flipper state, and claw state whenever they change. This provides
an external oracle for reconstructing and differentially testing the fixed-

The gameplay renderer drew the inactive table and then placed thin line flippers
and procedural circles over baked resting artwork. This left two flipper poses
visible at once, made the ball difficult to see, and ignored recovered animation
resources already embedded with the reconstruction.
Build an alpha-masked texture from the original ball bitmap and mask, erase the
baked flipper pose before drawing collision-aligned moving flippers, and animate
the recovered wheel, robot, and magnet sheets from their gameplay events. Add
bumper flashes, exact lit-table pixels for TILT, and a short visual table shake
for nudges so contacts and machine state have immediate feedback.
Test Plan:
- `cargo fmt -- --check` -- passed
- `cargo test --all-targets` -- passed
- `cargo clippy --all-targets -- -D warnings` -- passed
- launched the Linux window and inspected attract, gameplay, resting flippers,
raised flipper cleanup, and the masked ball sprite -- passed
- `git diff --check` -- passed
Starting from the attract screen previously created an idle ball and required a
second Down press to launch it. Launch the first ball as part of the start action
while retaining the normal launch action for later balls.
Replace the decaying visual-only tilt value with a latched game state. A tilt now
forfeits the current bonus, suppresses scoring and further nudges, returns both
flippers to rest, and remains active until the ball drains. Keep the warning on
the playfield and use the recovered tilt sound instead of treating the state as
a temporary decorative overlay.
Test Plan:
- `cargo fmt -- --check` -- passed
- `cargo test --all-targets` -- passed, including tilt latch, scoring, flipper,
drain-reset, and launch coverage
- `cargo clippy --all-targets -- -D warnings` -- passed
- `git diff --check` -- passed
