http://www.myspace.com/horsetheband Check them out, pretty neat band. They use a lot of nintendo sounds in there songs and dub themselves as nintendocore. Listen to "Murder" on their myspace for some intense nintendo action.
My thread about them was pretty unpopular I guess lol. I personally think these guys are super fresh and really put an awesome twist on metalcore. I don't care to call them Nintendocore (and they don't either anymore), as they're just a synth-heavy metalcore band (though an amazing + unique one)
