the reason why most people aren't heping you is that this game is coming to north america and they(myself included) do not see the point of hacking this game
any ways, it could be that the text is compressed and for images well joker#1 was pretty easy to find the images.
have you fiddled with the settings and searched multiple times though the rom?
find a file that you know has text that you know is not compressed open it in Emeditor and let emeditor autodetect the format to open that file if not reload it til you see the characters that you know should be there and then get a character code value (this will tell you what table file you need to use/ download and use to view the text in ct2)
otherwise use ct2 to decompress the rom and then search that if thers still no luck then its in the images and you already know how to look through that
