Ok well i'm new to the forums so... hey?
CA with no textures, make a new map somewhere on ur pc then open your combat arms map [nexon>combat arms>game]
You will see like 4 files that begin with TEX, Select them open ca and click start. Now quickly move the TEX files to a map and there you go.
This is useful for people with bad computers. [like me rofl]
Your own music: In your combat arms folder you will see a map called: BMG, open it.
There will be 2 files both are music file [1 for game lobby other for server lobby]
Pick a song you want to replace it with and name it like what it's called in the BMG map and now you can listen to your own music.
