To be honest, you're not missing too much. Nobody in the States really plays the game since anyone who cares about Darkstalkers is most likely on Savior, and nobody in Japan really plays it either since the version of Hunter that GGPO supports is the European version and not the Japanese version, which removed a number of bugs and glitches that the Japanese like. You'll find a couple of stragglers every now and then, but that's about it. I'd be down to play you, but I used my old roommate's PC since I have a Mac, so I no longer have access to GGPO since I no longer live with him.
