ddidderr d72db79af6 fix(physics): replace fitted flipper transfer
Remove the live-fitted upward and downward flipper polynomials. Port the
reconstructed 1000:7ed9 path with delta-specific pivots and record edges,
integer cross-product and radius gates, penetration, response-record gain,
wrapping velocity updates, and the final position delta.

Use resting records on press and the already-raised records on release, correct
the original delta direction, and apply each edge to both live ball slots. Keep
render-facing Vec2 projections, but adjust their float representation by ULPs so
every gameplay millipixel round-trips exactly instead of losing reconstructed
integer results.

Test Plan:
- `bash original/tools/test_reconstructed_c.sh` -- passed during raised-record reference capture
- `cargo test --all-targets` -- passed, 62 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md` -- passed
- `git diff --cached --check` -- passed

TDK Pinball Machine for modern PCs

This is a native Rust reconstruction of the 1995 Windows game TDK Pinball Machine. It uses the extracted original artwork and sound, recreates the playfield as a fixed-step simulation, and runs from the same source on Linux, macOS, and Windows.

The game opens at the original 640x460 canvas size and presents every artwork pixel one-for-one. The fixed, non-high-DPI client prevents desktop scaling from distorting or vertically offsetting the pixel-art presentation.

The original program is not required at runtime. All required game assets are embedded in the executable at build time.

Run

Install a current stable Rust toolchain, then run:

cargo run

For a distributable optimized binary:

cargo build --profile production

The binary is written below target/production/. On Linux, Macroquad's native development packages are also required (X11, OpenGL, and ALSA). Windows needs no extra runtime installation; macOS builds with the normal Apple developer command-line tools.

Deterministic mechanics validation

Named scenarios can be advanced without waiting in real time. The simulator uses exact 120 Hz steps, prints its final state as JSON, and can write both the complete step trace and the original-size 640x460 framebuffer:

cargo run -- --simulate claw-6 --at 0.15 \
  --trace /tmp/claw-6.json \
  --screenshot /tmp/claw-6.png

Use --step N instead of --at SECONDS to reproduce one exact update. The available scenarios are autoplay, launcher, flippers, claw-1, claw-6, claw-7, and claw-18; --seed N fixes random choices. autoplay charges each ball and operates the flippers from live ball position for long end-to-end validation runs.

Original and modern controls

Action Original key Additional modern key
Start game / add up to 4 players + = uses the same main-keyboard key
Charge launcher Hold Down arrow, release to launch -
Left flipper Left Ctrl A or Left arrow
Right flipper Keypad Enter Right Ctrl, D, or Right arrow
Nudge Space, Left Shift, keypad 3 Right Shift aliases keypad 3
Help F1 Enter/Escape returns
Settings F2 -
High scores F3 -
Sound F12 -

The five original speed choices remain available in settings. Physics now uses the original invariant 100 Hz millipixel substep, and claw animation follows the recovered 50/40/30/20/10 ms timer choices. Setting-specific repaint batching remains a presentation-only reconstruction boundary.

The help screen is the original artwork in English, German, French, Italian, or Spanish. As instructed on that screen, double-clicking its upper-left exit box closes the program.

Saved data

Settings and the ten-entry high-score table are stored as save.json in the platform's normal per-user application-data directory. On first run, the table is imported from the original HISCORES.DAT included with this reconstruction.

Reconstruction status

This repository distinguishes exact recovered material from behavioral reimplementation. See RECONSTRUCTION.md for the evidence ledger, known inference boundaries, and validation performed.
