Paper Mario: The Thousand-Year Door Cheats

When you get an important e-mail (ie; the e-mails from Princess Peach), wait a couple of seconds and you will hear music from Super Mario World.

In Glitzville, when you make a "comeback" after you beat Rawk Hawk the first time and fight your way to the finals, one of the spectators will, instead of cheering "Gonzales", or something to that effect, will cheer "Jumpman! I mean, who?" Jumpman was the original name for Mario before he was called Mario, IE back in the days of Donkey Kong Arcade.

After you sign into the Glitz Pit and win a few fights, come into the main lobby to see Rawk Hawk being adored by his fans. Use Mario's Hammer or Flurrie to get rid of the fans, and when all of them are gone, Rawk Hawk will get mad and scold you.

In X-Naut Fortress, go in to the ventilation shaft in sublevel 2 and drop through the far right vent in to the dressing room. Open the curtain of the stall you fall in to and Mario and all his partners will become 8-bit (they will look as they would on an 8-bit system like the NES) until you leave the room. Entering the room the normal way via the door and going in to this stall, closing the curtain, and opening it again will not work.
