The new Kameleons use five digit EFC codes rather than three digit EFC codes.

I never learned the rules for five digit EFC numbers. But several of the other JP1 experts did. It might be as simple as using 00085 instead of 085.

If it isn't that simple, I expect some other JP1 expert will correct me here.

If not, try this forum:

where you may get the attention of slightly more of the people who would know the answer. Be sure to mention that it is DVD/0539, since that may affect the 3-digit EFC to 5-digit EFC conversion method.
