CHANGING MESSAGE WINDOW SIZE WITH Y6 ENGINE

Is it possible to change the message window size (height and width) so that more text is able to be displayed? I'm thinking a placement of between the Middle and Bottom default placements, but extending all the way to the bottom of the screen so I can fit more into it.

Is it possible to do with the Y6 Message script?
If not, are there any other scripts that allow me to do this while being compatible with Y6?


EDIT: Another question, thought I'd post here instead of a new thread - I'm using the Splash Screen script by Jet10985, and while it doesn't conflict with Y6, the screen resolution isn't changed until after the splash is displayed. This ends up with a sudden size change after the splash, which isn't a huge problem, but looks terribly awkward and if there are any fixes, please tell me

Whoops, replied instead of editing the OP... sorry about that
