Decrypt and Encrypt game files

[Baddy2]

Ok so many people (included me) seen that game files such as .ini .bin .lua .txt ant etc. can be opened with notepads,wordpads etc. but content of those files are scrambled example:


And i wonder how to at least decrypt those files (that would be first step) and it would be great to know how to make game use decrypted and modified files or how to encrypt them back.
So anyone who could help some how give tips or guides or what ever useful info would be great.

Even if i dont think that they are realy "encrypted" ..
This will work allways:

Put the Game into a Debugger and look what it is doing with the files.
