Mario's TV:
First, beat the game on every file (100%) and then delete them all. After that, reset the game and rather than seeing the logo, it goes right to Mario's face and he says "I'm-a depressed, all that-a work for nothing" with the game over music and it says "Freak" in the background rather than "Super Mario 64." After that, it'll go back to normal Mario face (like after the Game Over screen) and be the normal game again. Next, play all the files in this order: B, C, A, D (like BC and AD) in less than twenty minutes. You should be on the D file last, so after beating that fight Bowser #2. He'll say "you look tired Mario, come to my house and let's watch some TV" while smiling happily. Choose "Yes" to go there, or "No" to fight him. When you choose "Yes..." the game freezes. You will than have to reset it. If done correctly, they'll be captions to everything Mario says. If you get normal or the depressed one, you either did it wrong or you didn't save. Anyway, if it was done right, there should be a file called "TV." Click that and you get to watch old crappy Mario commercials like the one for Atari (Mario Bros.), Nintendo Cereal System, Dr. Mario, and more. If you did the Luigi trick and got the 121st star, you even have an option to watch the Super Mario Bros. Super Show! This is not in any version but the American one or the Swedish beta version (where Mario constantly switches from Swedish to Japanese).
