OK for all of you guys who HATE the BGM in CA (kinda like me :P) Here is how:
1. Open up the game folder in your CA Folder which is located in your Nexon folder. Then look for BGM.
2. Then look for the MP3 named BGM_LOOP.mp3. Then If you want to add another folder and name it BGM Original.(remember you dont have to do this if you want.)
3. Now get the MP3 you want and copy and paste it into the BGM Folder and name it BGM_LOOP. And there you have it. Now every time you get on your CA game it will play the MP3 you want it too.
Thank me plz
