Replace the host-frame 10 ms publication loop with the original timer matrix: 50/40/30/20/10 ms callbacks execute exactly 5/4/3/2/1 internal physics substeps. Ball state, claw progression, and flipper geometry are now visible only at the selected callback boundary rather than leaking intermediate substeps. Separate flipper input flags from flipper position. Key changes are sampled by the timer, then produce one delta edge, WAVE 2021, collision response, and rendered position update after physics, matching the Win16 callback order. Clear both input and position state on turn reset and keep tilt decay on the same timer cadence. Test Plan: - `cargo test --all-targets` -- passed, 70 tests - `cargo clippy --all-targets -- -D warnings` -- passed - `rumdl check CHANGELOG.md README.md 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:
|
|
|
|
```sh
|
|
cargo run
|
|
```
|
|
|
|
For a distributable optimized binary:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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, 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, 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](RECONSTRUCTION.md) for the evidence
|
|
ledger, known inference boundaries, and validation performed.
