Add a bit-exact six-byte Real48 implementation for integer conversion, rounding, comparison, add/subtract, multiply/divide, and Newton square root. Use the normalized Borland random-register result and route speed clamps, segment/circle detection, moving flippers, captures, triggers, and magnetic fields through the recovered arithmetic instead of host floating formulas. Preserve Real48 spin per ball and feed it through the original tangent/spin response, separating zero-spin C fixtures from retained-spin Wine traces. Replace path-progress selection with surface-distance ordering and implement dynamic records 174/175, including impulse transfer to the other slot, normal_velocity-1000 response, and the second post-collision speed clamp. Test Plan: - `cargo test --all-targets` -- passed, 69 tests - `cargo clippy --all-targets -- -D warnings` -- passed - `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md` -- passed - `git diff --cached --check` -- passed

|
## [Unreleased]
|
|
|
|
### Fixed
|
|
|
|
- Add a bit-exact Borland Real48 core and route speed clamps, type-1 circles,
|
|
type-2 segments, moving flippers, capture pulls, trigger randomization, and
|
|
magnetic impulses through its original rounding behavior.
|
|
- Preserve per-ball Real48 spin and use it in collision tangent response, so
|
|
zero-spin C fixtures and retained-spin Wine traces are both represented.
|
|
- Implement dynamic records 174/175 with bidirectional ball impulse transfer
|
|
and the original post-collision speed clamp instead of a one-sided secondary
|
|
bounce.
|
|
- Split collision contact state into per-player 16-bit type-3 contact words and
|
|
transient type-4 entry flags. Type-3 records now use the original deep-inside
|
|
gate, `v*0.9 +/-150` pull, stationary sound/contact publication, 5-step age
|
|
progression to 300, and `99`/`2` completion sentinels.
|
|
- Replace the live-fitted flipper transfer polynomials with the reconstructed
|
|
`1000:7ed9` millipixel geometry gates, penetration, gain, response-record,
|
|
velocity, and position calculations for both directions and both balls.
|
|
- Preserve every gameplay millipixel across the float-only render projection so
|
|
exact integer physics results are not changed when stored for drawing.
|
|
- Restore launcher input to the setup scalar: each Down keydown subtracts 750
|
|
millipixels, release subtracts 1,500, then applies the recovered `-3800` and
|
|
`-2280` clamp/jitter branches and the ten original decoration thresholds.
|
|
- Apply the original independent `1.03 - Random * 0.08` X/Y velocity response
|
|
after entering radius-bearing type-4 targets, preserving both motion and the
|
|
subsequent shared PRNG sequence.
|
|
- Check every player against the high-score table when their own last ball is
|
|
lost, prefill the original `TDK Pinball Player` name, show the table before
|
|
resuming the next player, and use the original signed-high/unsigned-low score
|
|
ordering instead of selecting only the maximum score at whole-game end.
|
|
- Preserve each player's complete rule-record state across turn changes instead
|
|
of globally clearing wheel holes, top targets, 176 active/contact slots,
|
|
selected effect, and multiball readiness on every drain.
|
|
- Store lock-hole and effect awards in the original per-player secondary score
|
|
instead of a global bonus. The fifth hole now transfers
|
|
`310000 * score_multiplier`, clears it, increments the multiplier and ball
|
|
count, while effect 6 transfers the same display value and drain leaves it
|
|
intact.
|
|
- Replace the cooldown/float-meter nudge approximation with the original
|
|
Left-Shift, keypad-3, and Space formulas using scalar 15, the shared Borland
|
|
random stream, 32-bit velocity wrapping, and the decaying 16-bit `+25` tilt
|
|
counter with its randomized `30..39` threshold.
|
|
- Replace the Xorshift gameplay RNG with the original Borland linear stream and
|
|
unbiased `Random(n)` high-word mapping. Launcher variation, effect selection,
|
|
claw terminals, and magnetic-field impulses now share the recovered sequence.
|
|
- Restore the magnetic-field response as `vx * 0.9` and a randomized
|
|
`-3800 * (1 - Random * 0.3)` vertical impulse instead of a fixed upward speed.
|
|
- Dispatch the original per-call-site sound sequences instead of assigning one
|
|
guessed WAV to each logical event. This removes the nonexistent WAV 2022
|
|
playback and restores bank, trigger, capture, nudge, tilt, and drain cues.
|
|
- Advance media/extra-ball thresholds only from score additions, preserve
|
|
32-bit score wrapping, and restore the ninth-diamond 24,464-point award plus
|
|
the later double-score and secondary-score bank states.
|
|
- Match the original 640x460 window, native 16x28 score glyphs, and
|
|
`TDK Pinball Machine 1.00` title so the recovered artwork is presented
|
|
one-for-one instead of enlarged or resampled.
