Booty: Routine at 43012

43012: Controller: Draw Room

Used by the routine at PrintStatusBar.
On a new game, the game starts with the room ID being 0 (which isn't a valid room ID; InitialiseGameStates). The reason is that it chooses between these two set up routines here (and corrects the starting room ID in UnpackAllRooms).
