Thanks a lot.
This has tons of menus, most of them have text hardcoded (I mean, they are gfx, no simple way to dump them).
And I found a third table (I hope it's the last). I've identified latin/kanas, but there are still many kanjis.
Here are the glyphs :

And the table :
0123456789ABCDE
FGHIJKLMNOPQRSTU

Most of the menus for the 1st scenario are editable, and all the script too. I have found 240 kB of japanese text up to now (with redundancies as far I can tell), I don't know if there's still much.
Edit : realized there were 80 more glyphs. I just added them. I also noticed I forgot a katakana "ma", but it's fixed in the dumper.
