<BLOCKQUOTE>I've been working like a madman since I got my PassMe (about 28 hours ago now), reasonably steep learning curve, but here's what I've come up with. I'll release the source once I've tidied it up a bit - its not terribly readable at the moment.
I think I'm running out of texture memory, you notice it on the later models. Theres a few bugs on the texturing of the 3rd model.
This sort of works on the IdeaS emulator, but not very well. It has z-buffer issues, texture changing doesn't work properly, and the SELECT button doesn't seem to work at all. For full effect, run it on real hardware with the PassMe
