A member on the atari forums has released a hex editor and tutorial to make any car in RCT3 to work on any other track. Now you can get Extended Dive Machines and anything else your heart desires. I think people will be dusting off there RCT3 disk now. This has been tested and worked. Be careful though and make back-ups of everything otherwise you will have to reinstall all of RCT3.
