Basically there has been talk that the DVD9 (Full copy) of Super Smash Bros. Brawl does not work, this is not true, the full game does work, however there is a bug in the audio (located on the 2nd layer of the game) the way to fix this is to have a single layer copy of the game, can be found on torrents and the Dual Layer game (the full copy) this vid will show you exactly what you need to do to work around this bug. If you follow my instruction precisely, you should not have a problem.
