Nope it isn´t so easy tatsunoko seems to use fpk files with everything packed in it and at the moment there is no way to unpack them (at least i don´t know any tool haven´t looked for it a long time and i tried many programms) even then it´s still possible that they are packed again.
Anyway i´m pretty sure that the text in this game are graphics.
found this one yesterday it works on naruto fpk files

inside the fpk you will find brres files the biggest issue is finding the packers
its also worth looking in the games for the required tools i found this also whilst browsing
QUOTEI believe Naruto uses the same fpk files as this game and naruto actually includes all the un compressed files as well as the compressed files. It even includes the bat file they use to compress them into one file all that was missing was fpack.exe.
Hope this helps I can upload the files in both forms if it would help crack this format
