Just asking. Some tell me its possible, some tell me no. If yes, tell me how. I'd like to try.
Uh no. Metal Mario is only on Classic mode as a boss in that version. You can play as Metal Mario in SSBM by getting the metal box though, other than that it's not possable.
Mario + metal box = Mario with metal box
It's not possible to unlock metal mario. K *closed*
No, it's not possible. Same goes for all the "cheats" involving the Master Hand and all the other false characters.
