The original RandSeed is program-global and is initialized once at startup. Rust stored the exact Borland generator inside Game but discarded its final state at game over and seeded every following game from Macroquad again, breaking stream continuity across high-score/attract flow. Expose the current seed, retain it when the App consumes a finished game, and construct the next game from that value. Attract, high-score, and portable UI continue to consume no gameplay draws. Test Plan: - `cargo test --workspace --all-targets --all-features` -- 125 passed - `cargo clippy --workspace --all-targets --all-features -- -D warnings` -- passed - `rumdl check --flavor commonmark RECONSTRUCTION.md CHANGELOG.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 loading, attract, highscores, name-entry,
effect-7, autoplay, launcher, flippers, panel, targets, 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 | Keypad + or the main +/] position |
= is also accepted |
| Charge launcher | Hold Down arrow, release to launch | - |
| Left flipper | Ctrl (left or right) | A or Left arrow |
| Right flipper | Enter (main or keypad) | D or Right arrow |
| Nudge | Space, Left Shift, keypad 3 |
Right Shift aliases keypad 3 |
| Help | F1 | Enter/Escape returns |
| Settings | TDKPIN.INI before launch |
F10 opens the portable settings screen |
| High scores | Automatic when a player finishes | F9 opens the portable table viewer |
| Sound | F12 | - |
The five original speed choices remain available in settings. Physics now uses the original invariant 100 Hz millipixel substep, batched as 5/4/3/2/1 steps on the recovered 50/40/30/20/10 ms callbacks. Claw animation, flipper edges, and visible state publication follow the same selected callback cadence.
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, settings
are imported from an adjacent original INI (or the embedded distributed
TDKPIN.INI), and the table is imported from the original HISCORES.DAT.
Reconstruction status
This repository distinguishes exact recovered material from behavioral reimplementation. See RECONSTRUCTION.md for the evidence ledger, known inference boundaries, and validation performed.
