There are now at least three people working on getting Krystal playable in Star Fox Adventures. See some of their progress so far. Also, one of them might have found part of the old Dinosaur Planet demo code.
A Star Fox Adventures locale for your fighting pleasure. Now we just need a Krystal and General Scales mod...
What would Krystal have looked like if she had appeared in Star Fox 64? The Regressor helps figure that out with this free rig.
Dinosaur Planet, maybe? OK, probably not.
See how the games came to be.
