answered Need help with Black 2 ROM, mainly about changing the music.

Hi, I'm new to ROM hacking, and I'd like to know how to change the music on a Black 2 ROM. For example, things like battle music or trainer encounter music. I've searched online, but I can't find an answer, or at least one that I can understand. There's also other things that I'd like to know, like how to change the Xtransceiver sprites, item sprites, and battle backgrounds. I don't know anything complicated, and I'm mostly using KazoWAR's B/W Tools. If anyone can help me with anything I just listed above, it would be greatly appreciated. (Edit: I know where the files are located, but I don't know how to edit most of them.)(I realized I posted in the wrong forum after I posted.)

Editing music should be possible with something like this:

Unfortunately for everything else, I don't know enough to help with.
