The title screen, as you refer it, is the room where the player stays, usually paused, during the main menu.
This player's position can be easy set, by changing the values of two defines from the gamedef.gs file, PLAYER_MAINMENUX and PLAYER_MAINMENUY. By default, they place the player in the first of the three rooms, in the simple map of the default template.
Use proper values to place the player in your initial room. Usually you can set it as the top-left room of the map, but it can be any other.
Also, by default you don't see this room during the main menu, because the cover image is painted over.
This cover image is part of the "1 menu.tga" tile and, as it is implemented on the draw hud handler, it can be activated (visible) or deactivated (hidden) from a global variable, G_COVER. In the main menu it is activated.
If you enable the attract mode and leave it in the main menu for a little while, you will see Dizzy jumping randomly through this room.
See the attract mode article:
