As you'll see from the video above by Hard4Games, Hugo Peters has been working hard to find ways of getting new model files off of the Star Fox Adventures in-store kiosk disc. Of note this time are several near-complete in-game locations, a model for Krystal's companion Kyte, a beta Fox McCloud model, Krystal's first-person hands, and the log that Krystal rides on in one screenshot from Dinosaur Planet.
2Tie (who apparently has been working side by side with Hugo Peters) created an open source project that purports to be a Dinosaur Planet Model Viewer. Not sure if it actually works, but it was posted about here. Hugo Peters appears to have integrated the Dinosaur Planet viewing tools he made into his Warlock Engine, which doesn't appear to be available for public download at this time. However, if you're interested in tools for Dinosaur Planet (and other games), Hugo Peters made several of his older tools available on a project page for Dinosaur Planet Leftovers.
For even more Dinosaur Planet research, check out Heck Yeah, Dinosaur Planet!, this massive forum post about extracting the script (where 2Tie's Dinosaur Planet Model Viewer project appeared), The Cutting Room Floor's Star Fox Adventures entry, and a huge info dump by user Gilgamesh. Lastly, our very own site reader, kokorogensou, has both Story of Sauria, a blog dedicated to recreating the story and gameplay of Dinosaur Planet, and an organized Dinosaur Planet script using text found in the demo disk.
Thanks to Rozurabu and FoxTrot for some info found in this post.
