I am fed up with people saying that 8 player matches on Brawl are impossible because of the lack of costumes. I know that Ninty are not including anything more than 4 players, but not because of a lack of costumes
Not many people know this, but SSBM was originally designed for 6 player games (4 human and 2 cpu). If any of you were smart enough to invest in an action replay device, you can get ontot he debug menu and select previously unselectable characters such as Giga Bowser, Master hand, and even the Sandbag!
However, when coupled with another code (found on arcentral.net) you can actually play the 6 player games. This is awesome, particularly if all 6 players are the ice climbers so there will be 12 player models fighting per match.
Rep me if ya feel!
