New to the modding scene and WWE 2K in general..(noob questions)

[kbj]

I'd just like to ask about the different mod files here since it's all confusing and a bit overwhelming for a noob like me whose last WWE game was the SDvR series . I have been able to download some basic mods and got some of them to work(like a mod updating Ryback to his current attire) but I am still lost on a lot of things. I hope I can get some help regarding:

- What are pofo files/move set files and how do you install them or get them to work? set files and how do you install them or get them to work?
- What's this XPacker I see from time to time?  
- What are the Hex codes I also see in some of the posts here( I think they're Cheat Engine codes, but I don't know much about that)
- Is there any way to use custom music in this game?

I'm sure there are a lot more questions in my mind that I can't think of right now but any basic/advanced help with regards to modding and the WWE 2K games or modding programs in general would be greatly appreciated!

1-Pofo files are wrestler info files which are responsible for editing the name, height, gender etc....

2-X-Packer is the modding tool that makes everything possible. You install pofos using X-Packer and it does a lot more things too.

3-Hex codes are codes of files. You could mainly open everything in your pc using hex editor. If you're a starter stay away from hex codes, too complex for starters.

4-Yes, someone is working on a tool for that.
