Typographical errors

Typographical Errors or Typos in Super Mario 64 are grammatical, syntactical, or semantical mistakes in the game's text.

English

There are 4 known typographical errors in the US version of the game:

An error on the file select screen

An error on a sign in BoB

An error when talking to Yoshi

1. When copying a file on the File Select screen, if the player attempts to copy a file to a location in which another file is already present, the game will show the error message "SAVED DATA EXITS" (missing the first S in "EXISTS").
2. A sign on the island in the sky in Bob-omb Battlefield, explaining how to use the Wing Cap, begins by saying "Pull back to to fly up" (duplicating the word "to").
3. The decapitated snowman in Cool, Cool Mountain asks Mario, "Have you run in to any headhunters lately??" (using "in to" rather than "into").
4. Yoshi says "Mario!!! It that really you???" (using "It" instead of "Is").

All four of these typos also exist on the PAL version of the game.
