tyler ur a noob dude.he means glitching.ANYWAYS sephiroth the way to glitch for say has bin patched.there is one glitch called corners but ive only bin able to do that in market day.so i just use vertical clipping,and skywalker :).if u can get nitepr and cfw u can hack.use tuts if u need,and dont try glitching,or your scores will be deleted.
