Kytim, Turtles in Time ain't coming to VC. No chip is stopping it. It's called "licensing" and "not worth anyone's time at this point."
I love the game to death, but the Wii VC is a barren wasteland, and Turtles in Time would require a bit of effort to get on the service. That effort would be between Ubisoft and Konami, and I doubt other company gives a crap.
