From Bulbapedia, the community-driven Pokémon encyclopedia.
Inside of Truck (Japanese: トラックのなか Inside of Truck) is the location header used by Pokémon Ruby, Sapphire, and Emerald when the player is in the truck that appears right at the beginning of their journey.
Normally when the player exits the truck, no location header is displayed. However, in Ruby and Sapphire, if the player saves the game while Inside of Truck, reboots it, then exits the truck, the location header pop-up of Littleroot Town is displayed; this does not occur in Emerald.
In Pokémon Omega Ruby and Alpha Sapphire, it is instead labeled as ??? (Japanese: ？？？ ???), index number 114h.
