Daytona USA Deluxe, National Park Speedway.

The game's also (or perhaps better) known as Daytona USA Champion Circuit Edition on the Sega Saturn.

This is the pc version, using the D3D patch that Sega released after the initial game release.

To run the game under Windows Vista, set compatibility to an older Windows version (does not really seem to matter which one) and disable visual themes. Also, don't forget to set the installer's compatibility to Win9x or it won't install.

Blue blue skies forever! ;)

(the D3D patch is hard to find nowadays, get it at: www.samor.nl/DDX_D3D.zip) (less info)
