Thank you very much for your help.
I was able to build a table file for the dejap's English version, it's here if anyone wonder

Strangely, with the table file I can locate some Item and character names, but I can't find any dialogue with it. Perhaps the game is heavily DTE-ed, which is a nightmare to deal with. My focus is the original Japanese version but haven't found any thing with this one yet.
Lastly, may this be a stupid question, but what is the meaning of this offset $EC:6689?
I set a break point on read for this offset, then the game freezes at the begining of the first dialogue of the game. So it must be related to the dialogue anyhow...
I twisted the value at this offset and the game freezed.....
It seemed to be this offset is not the dialogue itself but some kind of information for the dialogue...
