You can make it bigger. I did it for XP, but never tried for VX.
Basically, you need to change Window_Message's height and add a new message code that will do the same thing as \n (new line).
Something like:
Hi!\NMy name is Ralph!\NBlablabla!\N0123456\NQWERTY
in a single line would Result in
Hi!
My name is Ralph!
Blablabla!
0123456
QWERTY
This should be easy to do. I don't have RM in front of me so I'll give you more informations about it later today.
Of course, the editor only allows you to fill up to 4 lines, but I'm sure there's a way to read the next message and append it to the current one. So you could have up to 8 lines (2 messages) in one message or even more.
Edit:
To create a new line code, go in your Window_Message, find def convert_special_characters and add
@text.gsub!(/\\L/)Â Â Â Â Â Â Â { "\x10" }
at the end of the method.
Then, find def update_message and change this line
when "\x00"Â Â Â Â Â Â Â Â Â Â Â Â # New line
for
when "\x00", "\x10"Â Â Â Â Â Â Â # New line
Now, adding \L in your message should create a new line.
I can't test this because I'm at work, but it should do the trick.
Take care!
