File Decoder

A game client uses encrypted files, only the client knows how to read it.

I need someone with knowledge on reverse engineering to debug the client check how the client is decoding/reading the files and create a program to replicate it.

The program can be coded in any language as long as the product is in windows binary.

One set of the files has the extension `.bin` this file is encypted, and the client reads it by XOR'ing it to 0x14.

There are more sets that I don't know how to decode yet, that's the job.

Points:

Understand how the client reads the files/data.

Create a program that can do it, so I can edit these data.

Game client,

You can use OllyDbg or any debugger you prefer to reverse engineer the client.

Files to be decrypted,

Legal Issues,

First thing I would like to point out is that we host the game itself and this is an effort to further develop the game. Then the question would be why don't I just ask the developer itself to do this. We'll the develop ceased to exist back 2009.
