You cant, there is no playable character as Metal Mario.
You can get a Nintendo 64 GameShark at GameStop for $34.99, the GameShark has cheats for any game you can think of!!!!!!
Super Nintendo
You cannot unlock Metal Mario, as he is not a playable character. The only way to play as him is to cheat and use the Gameshark.
There are none.
You can't. It would be suicide anyway.
of course not it's a nintendo game.
Mario is owned by Nintendo, therefor Mario games can only be played on Nintendo consoles, without hacking or using an emulator.
They are ghosts that are by the Nintendo staff. But unlike the regular Nintendo ghosts, these are very fast and hard to beat. To unlock an expert Nintendo ghost, you need to beat the regular Nintendo ghost by several seconds to unlock the expert ghost.
You start the game as Yoshi. He has to unlock Mario, who then has to unlock Luigi, who then has to unlock Wario. (See other questions to find out how.) If you have an Action Replay card, if you find the right codes you can play as other various characters. Although some people even say that Waluigi can be unlocked without this... but that's another story.
If you are talking about Super Mario 64 for Nintendo ds The answer is yes. If you beat alot of levels (i forgot which level) you can unlock luigi but it takes practice. You can unlock wario too.
