Answer to question 1.
No it is not possible without being able to hack into the scripting part of the maker itself. Reason for this is because, the game would be unable to find and located the map files. As it currently set, the map files are found in local folder, or " project/ " Now if one was able to make it happen it would have to be through the Rpg_RT document. Which leads to question 2.
When opened you should see
[RPG_RT]
GameTitle=[current name of game]
MapEditMode=0
MapEditZoom=0
Where the line says GameTitle=[current name of game]
Just change your game name in that area without the brackets.
so if you wanted to name it The lands of hope
GameTitle=The Lands of Hope
hope this helps.
