What a LIE! I saw those pics a while back and they were proved to be wrong. Luigi is basically a vertically stretched clone of Mario. Look how blocky it is around Luigi while Mario is not.
With those fake pics was a stupid, long, and annoying procedure. I read one part of it. The last thing of the dumb list was in Lava Lava Land, you were supposed to jump in the volcano, then jump in the lavafall. It would then warp you to Jolly Roger Bay where you could have the Metal Cap just long enough to open that box with the skull on it that slides on the sunken ship. It said when you broke, it would have a Luigi's hat in it. Mario would pick it up, say "Here we go!" then magically turn into Luigi. Or that you and Luigi could switch off at any point during the game.
Although, they had an idea to put Luigi in, but the confusion of saving and memory limitations forbid even thinking about Luigi to be put in the game. You know how Mario's head showed up on save file? Well, the confusion with his head and Luigi's on the save file would be too much trouble.
I'm probably wrong, but that's what I read about.
Well, to sum it up, Luigi couldn't be in he game and you need to take your fake pics back to where they originated.
Hey folks, you should try this. Show people your drivers license and ask them if "they have seen this man."
