 * In Super Mario Bros., if the player manages to get 128 or more lives, they will receive an instant Game Over should they die again. The game interprets more than 127 lives as an negative number of lives due to the Two's complement system.
 * In the Frantic Factory level of Donkey Kong 64, an original arcade machine can be found. If Donkey Kong has learned how to pull levers, he can play the original game (as Mario, though). In order to reach King K. Rool, this game must be completed twice up to the last level, with Mario starting out with one life and able to gain one more each per 10,000 points.
 * In the Game Boy Advance remake of Super Mario World, a player can earn a maximum of 9,999,990 points.
