-made wait animation faster -removed a few unneeded lines in the wait message code -fixed booting wii games from disc -fixed possible bug in wii game launching in general -gecko output again on wii game booting -converted alot of spaces to tabs, fitting the general wiiflow coding style -general cleaning up things
