Where in Time is Carmen Sandiego? (NES)

Easter Egg
‎ You start the game from the elevator on the Lobby floor. Head to the basement, and enter the "CREDITS" door in the Boiler Room. Once there, hold Right and press A, A, A, B, A, Start, A, Select, A, Select, A, Start, A, B, A, A.

After doing this, "ERIK T. KISS" will flash for about two seconds.

Now head to the Personnel floor and enter the personnel apartment. Instead of San Francisco, the starting point of your travels will be Vancouver. The game's developers originated from Canada, and DSI has had its headquarters in Vancouver since 1991.
