BlazBlue doesn't use GGPO, in fact, no game company actually uses GGPO. Capcom licensed the algorithm for it from Ponder, but actually made their own netcode based off the GGPO coding. Other than that no one has used it in the least. Arc System Works and Aksys Games created their own netcode from scratch and it for the most part was superior to the SFIV netcode based off of GGPO. The only better netcode that exists is the VF5 netcode. SNKP USA could just be a 'red herring' used as an end run around dealing with Western Fanbase complaints.
