I am very excited in this game and I want to translate it for Korean.
But Korean translation patch for Civilization4 change CvgameCoreDLL.dll in Beyond the Sward fitting to that patch. So I could not execution the game. I deleted CvgameCoreDLL.dll in FFH2 mod pack. Then game was executed, but interface of game disappeared. Can I play the game without CvgameCoreDLL.dll in Mod pack? If I can, what should I do?

There's no way to play without the DLL, but it is possible to merge another patch into it if you have the source code for the Korean Translation patch.

Yeah, the dll is quite important to FfH. You could try merging the source files of the patch with the source files of the FfH dll and recompiling, but I'd probably find it easier to just edit CIV4GameText_FFH2.xml, replacing the text of one of the languages that FfH isn't translated into (Spanish of or Italian) with Korean (that is if I knew Korean, and assuming that the text file can handle the Hangul alphabet)

Would you help me to merge the Cvgamecoredll.dll from Korean Translation patch? I don't have any knowledge about programming.

The download for the first file doesn't seem to work - if you can host it elsewhere or fix it, I'll take a look at the changes and see what can be done.

Do you know if the sourcecode is available (the .cpp and .h files that make the .dll)?

The initial file you posted had "sdk" in it's filename - it's the SDK (source)files that are needed to combine two different DLL files. Sadly it can't be done without them.

I fix the problem to execute using new Chinese translation patch. But when I start the game with Korean Language, all of interface didn't appear. So I changed language to English and executed. Then all of interface appeared! Then I changed the language in game option while play the game. Interface didn't disappear! What happen? Can I start the game with Korean?
