Most (all?) Playable Fighter ships (and the Great Fox 2) have been ripped by Nooga and are available for download. This includes Krystal Cloud Runner ship.
This is what Krystal probably would have looked like in-game if she were around for Star Fox 64. Free download on The Models Resource.
16 different Star Fox Adventures location models, and a bunch of Krystal textures, models, and sound effects I hadn't yet posted.
The floating Krystal head, and two versions of Krystal's Staff have been ripped from Star Fox Adventures.
Both Krystal trophies and Krystal from Adventures included!
