FF3usME: Problem to export FF6's script

The "gibberish" just seems to be pointers to where the characters are located. Notice how all of the kanji start with "BK", but none of the hiragana, katatana, or numbers do.

For example, look at the number 1000. That's being rendered as <$54><$53><$53><$53>. That gives us a starting point, at least, where we know that
<$53> = 0
<$54> = 1

I'd be willing to guess that
<$55> = 2
<$56> = 3

The katakana is a bit trickier. The "no" character is listed as <$9B> in both instances, but the 2 "ka"s are 2 different hex codes.

Anyway, once you figure out what's what, you can export the script, go into Notepad++, and do a "find and replace all" on each character. That kanji's gonna be tough on you though.
