Step 1: MAKE A BACKUP OF "iw_13.iwd"! THIS IS CRUCIAL IF YOU EVER WANT YOUR OLD FILES BACK!!!
Step 2: Rename the music you want to "bt_mp_menumusic" without quotations.
Step 3: Now, here's where shet gets tricky. Go to the Hexic editor, and open your wanted music (Renamed to the above^) and the original music.
Step 4: Grab the original music's first two lines of hexic characters, copy and paste it into the first two lines of the music that you want. Then scroll down to the very bottom, and delete the last 4 hexic digits. (8 numbers/letters/both)
Step 5: Close the hexic editor and then open the CRCFixer. Copy the Original Menu Music folder address, paste it into "Original". Copy the "EDITED" folder address and paste it into "New". Press Execute, and then wait for a moment. Once the bottom loading bar is full green, give it 6 seconds, then press quit.
Step 6: Open "iw_13.iwd" with WinRAR, and then go to "sounds/music"
Step 7: Drag and drop your music into the folder, let it finish compressing.
Step 8: Close the window, and you're good to go!
