Paper Mario: The Thousand-Year Door

In the modern age of data mining, its not uncommon for nearly every game or patch’s secrets to be outed within weeks of release. Back before the internet was quite so prevalent, secrets in games remained just that for sometimes years before the knowledge would enter the public consciousness, and many games from that time no doubt still contain little easter eggs that no one has managed to uncover.

Paper Mario: The Thousand-Year Door was one such game, up until recently, as data miners have now uncovered the debug code for the game. If you go onto the title screen and input “XBRBYL” debug mode will be activated. This doesn’t really do anything, but holding down the Z button will reveal the date that the game was made. Additionally, crash reports will be generated if the game happens to crash.
