I still need to do a lot of work, but here is a very early version of the MOTHER 3 script listing. The entire game script is here, but things like battle text, menu text, etc. isn't included at the moment. The script isn't stored in a logical order in the game, so one thing I'm going to do at some point is reorder things for easier browsing.
I also intend to highlight all the unused lines and provide interesting notes for many lines of text. I have much more planned too, but I'm always busy with lots of projects and I need to set this one aside. That's why I'm showing this early version now.
Anyway, enjoy!
