A 3GB archive of Spirit of Speed 1937 and 2002 (PC and Dreamcast) has been preserved. After reflection, I am not able to propose it to you.
It includes promotional, marketing, conceptual and explanatory documents about some of the game's development tools (3D Studio Max 2.5, level editor, engine etc.). The archive contains the source code of the Unreleased version of SOS 2002, development tools such as the track editor and a variety of assets (different build) for SOS 1937 such as cancelled tracks (to be confirmed).
This article allows you to see the contents of the archive and learn more about Spirit of Speed 1937, a game created by the development studio Broadsword Interactive:
