Replace the overlap-and-separate circle approximation with the original swept ball-center entry test and radial/tangent fixed-point response. Preserve every type-1 record's Real48 rebound and tangent coefficients, plus the bumper normal 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. Test Plan: - `cargo test --all-targets` -- 44 passed - `cargo clippy --all-targets -- -D warnings` -- passed - `cargo build --profile production` -- passed - 20-second deterministic launch traversed bumpers and drained without rescue - live object 155 and bumper 51 fixed-point transitions matched exactly - `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 960x690, an exact 1.5x enlargement of its original 640x460 canvas, so modern desktop scaling cannot distort or vertically offset 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 launcher, flippers, claw-1, claw-6, claw-7,
and claw-18; --seed N fixes random choices for later seeded scenarios.
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, either Shift, 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; exact setting-specific timer batching for presentation and mechanism animation remains under reconstruction.
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.
