Sigh... Games load files off of their respective discs/sd cards. That means that your hack will not magically transfer over to the other person's game. Unless he/she has the same exact file under the exact name, it will not work. Plz lern 2 online games.
For the brawl vault sig go here. http://forums.kc-mm.com/Gallery/Sig.php For my other one just upload to photobucket or flickr and they should give you an IMG code, photobucket does for sure, dunno about flickr though. That is what you need to have images show up.
Is there such a thing yet to create a model from the ground up to work w/ brawl? Going to school soon so I will have access to all sorts of industrial software. i.e. 3DS max... Autodesk Inventor... Maya.
