If you want, add me on XBL since I live in NY and you're not that far away from me in Boston. I have a friend who I play and he is in Florida. We actually get some decent matches in. At most, maybe 3 out of 10 will have noticeable lag input.
As a Mac users myself, it's killing me that GGPO and all those other online services are Windows only. I'm eventually just going to try to find someone who knows how to install boot camp on a Mac so I can run a Windows partition. Yeah, it'll only be for GGPO, but at this point I really would love to get the ability to play KOF98, 2k2 and Garou online right on my laptop.
BTW, XBL GT is Positively Ralf. add me and let's see what kind of matches we get in. hopefully not so bad knowumsaying?
