I don't think he can.
Play 2 player mode and player 1 is Mario. Player 2 is Luigi.
You can't be first player because it makes you be mario, but if you are second, third, or fourth you can choose.
The only way to play as Luigi in the original SMB is in the 2-player mode. Luigi is player 2.
No!You Can Play Up To Four Player As Mario,Luigi,Yellow Toad Or Blue Toad
No.
You can’t play as luigi in Super Mario 64! Because he is not in the game
You can't. You can only be Mario unless you hack the game, which is not reccomended. If you are playing the DS remake, you can put Luigi's hat on and become Luigi.
I know that you can play as luigi on new super Mario bros for ds. You do this by holding L R and A when your chosing your profile
Luigi's counterpart in Super Mario Bros is his brother Mario.However, he has an "evil" opposite Waluigi (bad Luigi) who first appeared in the game Mario Tennis(2000). He appears mostly in spinoffs starring Wario.
There's no such thing as Luigi in Super Mario 64
In the original you can play as Mario and Luigi. In New Super Mario Bros DS you can play as MArio AND LUIGI. IN NEW SUPER MARIO BROS WII ITS MARIO, LUIGI, BLUE TOAD, AND YELLOW TOAD.
