Pre-release
Pre-release
Drag v0.10.0-beta.2
An updated, free Windows demo beta for two- and four-lane slot-car drag racing.
No track or controller is needed to try the software.
Download And Start
- Windows x64: most Intel/AMD Windows PCs.
- Windows ARM64: Windows on ARM.
- Extract the entire ZIP, then double-click Start-Demo.cmd.
- Click New Demo Tournament for sample racers, cars, and simulated heats.
- Packages are self-contained; no separate .NET installation is required.
SHA256SUMS.txtsupplies the checksums for both ZIPs.
New Since Beta.1
- Help menu: demo instructions, wiring, a four-lane commissioning checklist,
beta bug reports, About Drag, and Copy Version Information. Copied information
includes app/platform/controller details, not racer data or local paths. - Explicit result sources: confirmed tournament rows retain Simulated or
Controller labels through restart, history, and HTML/JSON/CSV exports.
Reports warn when simulated results are included; mixed-source tournaments
retain the individual row labels. Practice results also show their source. - Print-friendly reports: landscape pages, repeated column headings, wrapped
names, compact summary, and rows kept together where they fit. Modern-browser
PDF output was checked with a nine-page long-name stress report. - Commissioning worksheet: pin maps, sensor and Tree checks, moving-car pulse
measurements, trap-distance records, simultaneous-lane tests, and venue sign-off. - Focused GitHub beta bug-report form and updated sensor mounting documentation.
JSON archive schema is now version 3; CSV adds ResultSource. Unclassified
records are Unknown rather than inferred from tournament names. Controller
firmware remains DragMC 0.6.5; this update does not change its timing or pins.
Important Limits
- Experimental prerelease: moving-car and simultaneous four-lane track
qualification remains pending. Demo results are not hardware measurements. - Demo and normal operation use the same local database and settings.
- Unsigned Windows application: a publisher/security warning may appear. Use
the official download and do not disable Windows security protections. - x64 startup was tested on the development PC. Fresh-PC warning behavior and
this exact ARM64 package's runtime behavior still need independent testing. - Prior builds worked under Wine 11 on Intel Linux and ARM64 Wine 11 on Rock 5B;
that does not constitute runtime validation of this exact package. - Piper/models and avrdude are not bundled. Speech is optional and off by default;
firmware updating obtains its verified uploader separately. - Mega firmware uses 6,711 bytes (81%) of SRAM, leaving 1,481 bytes.
