No. This is a myth. Luigi was never programmed into the game to begin with. There WAS talk about it if you do your research and discover he was supposed to be a "PART" in the game as NPC's are concerned.
You can’t play as luigi in Super Mario 64! Because he is not in the game
There's no such thing as Luigi in Super Mario 64
Wauligi was not included as an Unlockable Character in Super Mario 64. Thanks for using Answers!
You can not unlock Luigi in super Mario 64 without hacks, but he is playable in super Mario 64 DS
Because there was no room in the game for him so Mario fired him..

Luigi is not in Super Mario 64. But he would likely just be Mario with a green shirt, green hat, and an L on his hat.

In Super Mario 64, Wario is not Unlockable, nor any other character for that matter. However, he was added in the DS remake. You'll get him through normal gameplay though, because he is needed to complete the game. (Unless you're a glitchy speedrunner mess)
No. the luigi costume only works with yoshi.

Link is not a character in Super Mario 64 DS. The available characters are Yoshi, Mario, Luigi, and Wario.
