I'm new to these forums and really could use some help.I've seen on You Tube SSBB played with characters like Shadow Silver Knuckles etc. and with extra characters as well. I've loaded homebrew and Gecko and want some codes  or gct files.Please excuse me for not being well versed on this.I've tried to find the Brawl packs and cannot.Can anyone steer me in the right direction? Thanks.
