mrsinister sent me a dump of an upgrade kit for California Speed that updates the game from 1.0 to 2.1a. I'm not sure if it will be too useful or not, but it could be hooked up so that the update could run in mame, and also there is a chance it could make a cleaner version of 2.1a than we have. He also bought a few boxes of rom chips from an old arcade op to sort through. It could have undumped game revisions.
