Not sure how many of you guys know this but Real Bout Fatal Fury,Last Blade, Fatal Fury Wild Ambition, and Samurai Showdown Warriors Rage has hit the the PS3 store. the only catch is they are available for the hong Kong store and no word form SNK yet if we will get them on the US PS3 store yet. Also Galaxy Fight has hit the PS3 Store in Japan.
Maybe some HK SRKers can give some insight on how they play on PS3. As far as I can tell all of them seam to be the PS1 ports judging by the art they are using for them.
