Does anyone know where I can find Japanese video game scripts, with or without translations? Specifically, I`m looking for Twilight Princess. Thanks!

I don't know of any game script repositories or anything like that, but I usually have pretty good results by searching Japanese Google with a unique quote from the Japanese game script I'm looking for. I got most of the Final Fantasies that way.

You could also rip the scripts from the games yourself with a little bit of work.
