Help [Resources request] - Learn to edit L2 client files

[MiniShop]

Hello all,
 

Developer for over 10 years but only lately I've started to fiddle with L2 client files, I'm a complete noob at this.

Are there any resources I can have to learn how to decompile and re-compile the files that ship with the game?

I have a ton of compilers and decrypters but can't make sense of how to use them and for what scenarios.

 

Understanding the files' structure an what they are doing would be a great start.

If you have any links/documents to share would be great!

 

Thanks in advance

Which files were you looking to decompile exactly?
