OpenTTD before 1.0.0 requires the original Transport Tycoon Deluxe data files in order to function. For OpenTTD 1.0.0 you can use the original Transport Tycoon Deluxe data files, but also it's free alternatives OpenGFX (graphics) and OpenSFX (sound). Please refer to the readme for more information.

For all binaries officially released by us we publish the MD5, SHA1, and SHA256 checksums. You can use these checksums to check wheter the file you downloaded got modified. All three checksums should match the file you downloaded; if this is not the case it means that either the file didn't came from us or that it got broken during transport. Either way it might possibly contain dangerous modifications and the file should therefor not be trusted!

Latest release in stable is 0.7.5, released on 2009-12-23 20:01 UTC.
