Testing Methodology

This website is a statically generated HTML project. Technical checks cover its packaged HTML, links, assets, canonical tags, metadata, sitemap, structured data and JavaScript click handlers.

What a successful test means

A passing FileDrop event-handler test means the browser invoked the configured download function. It does not prove the remote service returned a file, that the file is safe, or that the resulting installer matches Transport Tycoon Deluxe.

What has not been claimed

We have not established verified Windows 10 or Windows 11 installation results for the original commercial 1995 executable, nor have we authenticated external game binaries. For current OpenTTD behavior, refer to its own documentation and official releases.
