TTDPatch - The Transport Tycoon Deluxe Patch

Development versions

Current version: 2.5 beta 9 from October 29, 2006.

• latest.zip for DOS TTD
• latestw.zip for Windows TTD

You can read the announcement with any instructions or notices about this version in the mailing list archives.

Terminology:

• Alpha is a development version not tested by anyone but myself, and may or may not contain serious bugs. Please be aware that it might crash or hang TTD, or your computer. It probably won't, though.
• Beta has already gone through a fair amount of testing by other people, and should be fairly stable, but might still have some rare bugs or crashes.
• Nightly is the current state of patch development, compiled each night. These versions are extremely cutting edge, they contain the code as it is being developed and may be very unstable. These builds are available on nightly.ttdpatch.net (thanks to Patric Stout & Miham Kerekes for providing them).

For even more cutting edge code, feel free to browse or check out the TTDPatch Subversion repository (graciously hosted by Owen Rudge).
