There's some stuff in the japanese version of FFT that never made it into the english version. It mostly seems to be some mini-games, and some novels that you could read. I checked youtube, but strangely, no one has played the japanese version and uploaded videos of this content. Does anyone know where I can see what this stuff was?
From gamefaqs:
QuoteScore challenge mode (Japanese version)
Obtain the Book Of Life in Chapter two. Stop reading the book before reaching the "Good Ending". Then, read through the book again to access a hidden "Score Challenge mode". This mode allows the Chocobo Race sequence to be played for money.

they completely removed the sound test and I don't know about the sound novel routines yet.
I want to reactivate them sometimes though.
I don't know where you could find videos about this though...
Nicovideo would probably be the best spot (it's like a japanese youtube). However, I wouldn't know what the proper search terms would be to search for them.
