HEY, Here is how yu can change your music in combat arms this works for the lobby adn when yur in the game lobby(getting ready to play)
this is pretty easy to do i dont think you will need help with anything but if yu have any troubles doing this message me
Step 1: download your favorite MP3 song!
Step 2: go to C:\Nexon\Combat Arms\Game\BGM
Step 3: Take out those BORING music and put em in your desktop
Step 4: Place your MP3 file into the BGM folder (make sure you make an extra)
Step 5: Rename your MP3 file to UIBGM_LOOP for the login theme and others, Rename it to WAITINGROOM_LOOP for the waiting room
Step 6: Open Combat Arms!
I've tried this it does actually work! now you can listen to your favorite song while you wait!!
