Correct the coordinate model from guessed 16.16 values to the millipixel arithmetic shown by the 16-bit division routine.
Decode the Borland Real48 direction constants and record the exact position and velocity tables used by every claw terminal.
Test Plan:
- git diff --cached --check
- Compare constants against segment 1 disassembly at 9bca and eab1
Replace the broad robot bounce rectangle with the recovered object-89 capture state machine. Suspend the live ball, advance the exact sprite rows, release from decoded original coordinates and directions, and keep the surrounding collision records disabled until the arm returns home.
Render the 900x296 sheet as 100x74 frames at the original destination and suppress the duplicate ball while it is embedded in the capture animation.

Play the original WAVE resource for both movement edges of each flipper and centralize gameplay event sound selection.
Replace guessed control and mechanism mappings with the resource numbers recovered from the Win16 call sites. Keep synthetic ball search silent because it has no original trigger.

Transcribe the claw and flipper control flow into an address-mapped readable companion while preserving unresolved fixed-point projection as an explicit boundary.
Correct the reconstruction ledger so the current Rust claw is not described as proven parity.
Test Plan:
- git diff --cached --check
- Review restored constants and branches against TDKPIN_GHIDRA_RAW.c
Match the recovered Win16 registration flow: the first plus press creates Player 1 and additional presses add Players 2 through 4 until the initial launch. Down now belongs only to charging and releasing the plunger.
Test Plan:
- cargo fmt --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- live: verify Down cannot leave attract mode
- live: start with plus, add Player 2, hold Down through partial/full plunger frames, and release onto the table
- git diff --check
Advance the recovered eleven-frame plunger over a full one-second hold and use that same frame selection for rendering. This makes a short tap visibly and physically weaker while a complete pull still clears the shooter lane.

Replace the reversed oversized flipper vectors with the original binary rest
and raised geometry. Render the exact resource 997 flipper rectangles while
pressed and keep the live collision capsules aligned with those sprites.
Test Plan:
- cargo fmt --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- compare forced raised-state rendering with the extracted resource rectangles
Use the recovered rail rebound coefficient and let a launched ball cross object
22 in the exit direction after the upper curve. Strengthen the launch
regression so a momentary lane crossing cannot hide a later rebound.
Test Plan:
- cargo fmt --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- verify the charged launch trajectory at detail levels 1 through 5
Compose the running table from the recovered resting bitmap and exact active
UI regions. Remove the procedural replacements that distorted lamps,
flippers, player rows, and display values, and place the plunger strip at its
recovered destination.
Test Plan:
- cargo fmt --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- launch the game and compare the initial frame and charged plunger visually
Start each ball at the recovered right-lane coordinates and charge the
plunger while Down is held, firing only on release. Render all eleven frames
of resource 901, preserve object 25 as the returning-ball catch, and use the
object table's center-contact extents without adding the art radius twice.
Test Plan:
- cargo fmt --all -- --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- runtime smoke: start, hold Down, release, and inspect the right shooter lane
Replace the mirrored, partial wall transcription with all active static line
and circle objects from the Win16 registration table. Preserve the original
object IDs for drain and shooter-stop handling, and use bounded physics
substeps so fast balls cannot skip thin rails.

A cabinet nudge could still raise the tilt meter after a drain while the next
ball was parked in the launcher. If that latched TILT, launching was correctly
disabled but no active ball remained to drain and clear it, creating a new
softlock.
Only accept nudges for an active ball. This keeps the latched tilt rules intact
while guaranteeing every waiting ball can be launched.
Test Plan:
- `cargo fmt -- --check` -- passed
- `cargo test --all-targets` -- passed, including the waiting-ball regression
- `cargo clippy --all-targets -- -D warnings` -- passed

High-DPI sizing and a resizable client allowed the 640x460 canvas to be placed
inside a much taller window, producing the large internal black band captured in
the gameplay recording. Open an aspect-correct fixed 960x690 client with high-DPI
framebuffer scaling disabled, giving every platform a predictable 1.5x canvas.
Use exact active-table patches for the cyan score fields and derive transparent
numeral glyphs from the recovered Win16 bitmap font. Fill the complete display
slots, move the KBytes readout clear of its border, and place shortcuts on a
readable footer so no dynamic text is clipped or left over an inactive panel.

- `cargo fmt -- --check` -- passed
- `cargo test --all-targets` -- passed

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

- launched the Linux window and inspected attract, gameplay, resting flippers,
raised flipper cleanup, and the masked ball sprite -- 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

The recovered bottom apron had been represented as one solid collision segment,
which prevented the ball from reaching the drain threshold. Split that apron
around the visible center drain so a lost ball decrements the ball count and
allows player and game-over progression to continue.
Add a conservative ball-search impulse after three seconds below the movement
threshold. This protects long-running games from other low-energy rests without
changing active trajectories, and reuses the original nudge sound as feedback.
Test Plan:
- `cargo fmt -- --check` -- passed
- `cargo test --all-targets` -- passed, including drain and ball-search regressions

The source copy preserved executable permission bits from the evidence archive
on HISCORES.DAT and TDKPIN.INI. Keep their exact bytes while recording them as
ordinary embedded data files in the reconstruction repository.

Replace the empty Rust scaffold with a playable native reconstruction of the
1995 Win16 game. Embed the complete decoded asset set, retain the original
640x460 presentation and localized help, and implement a resizable letterboxed
Macroquad frontend for Linux, macOS, and Windows.
Recreate the multiplayer ball flow, flippers, nudging, target banks, wheel,
robot, lock, magnets, bumper progression, TDK diamond multiplier, media extra
balls, sound dispatch, settings, and high-score entry. The physics engine uses
a fixed time step and 101 static collision segments transcribed from the
original 175-object table. Portable JSON persistence imports and decodes the
original XOR-obfuscated high-score file on first run.
Document the evidence boundary explicitly: artwork and PCM samples are exact,
static geometry is recovered, and several numeric scoring/impulse values remain
best-evidence behavioral tuning rather than bit-identical Win16 arithmetic.
Add a native three-OS CI matrix and retain every decoded resource for future
fidelity work.
