How to merge DBC files?

[mo9h0st]

Can someone tell me how to merge DBC files in Update directory?
(exactly achievements.dbc, achievements-category.dbc, achievements-ciriteria.dbc in wow-partial.MPQ.)

Remember those are different files from ones in Data/locale. ones in data directory are old, including test version, before wotlk data.
wotlk data is from update/partial-1.mpq file.

I'm using MPQEditor, TALIIS. I'm sure it works fine. the problem is opening, using dbc files in update/partial-1.mpq. When you extract it and open, it's not the dbc files but BSDIFF files. And still not the BSDIFF, blizzard modified ver BSDIFF.

After i tried to figure out the header information and modifying BSDIFF program by myself, I just think it's way to far i can't get.:confused:
so please. can anyone tell me how to patch this files to original(in Data directory)? or i'll just lnk 2 zipped DBCs that one from LOCALE mpq, one from PARTIAL mpq.

tell me how or hack it plz. my eyes are going to bleeding. spend so much time to know how.

here's the link
locale dbc
partial dbc

And i know there's merged achievement.dbc files for eng version and i have ti.
but i still need for korean locale version.
