The only 100% way to know if its D2C2 is to try and mod it. If the chip you're using doesn't work, you need the D2Pro9 v2 chip. I've been trying to get this chip for a while now. Couldn't find it in Montreal, couldn't find it in Boston, and now I can't find it in New York City. I hear it'll be shipping in a week or so. Just hang in there, the other companies are out there working on this problem. It might take a few weeks, but they WILL release something and the new chips WILL ship.
