So, I'm posting some research done by daniilS. The content of this whole post should be credited to him. The offsets here are for Firered.
In order to change the xy position and the height and width of the textbox in the overworld, you just have to make some simple byte changes. Keep in mind, the positions and sizes are in tiles, so you may need to divide your needed dimensions by eight for things to line up.
To change the x coordinate, change the byte at 0x41F42D.
To change the y coordinate, change the byte at 0x41F42E.
To change the width, change the byte at 0x41F42F.
To change the height, change the byte at 0x41F430.
Fortunately, the text itself will automatically adjust to its relative new position in the box. Here's a link to the rboxbase's code.
