http://goldeneyevault.com/viewfile.php?id=37 The exhaustive GoldenEye / Perfect Dark editor just received its first major update in eight years. Among its features is preliminary support for three more titles: Diddy Kong Racing, Jet Force Gemini, and Mickey's Speedway. Yes, Rare used a racing game engine for Jet Force Gemini...
Pretty cool, the number of features this has is quite ridiculous! Wish I had more time to go back to work on my N64 projects
