The begin

First post smell like shit. But I want to improve my knowledge. And I´m here to suggest create a tutorial about the begin. No, I wont to take my hand and say : oh! little boy! Do u want icecream ? What flavor ? No !
I want to learn and I ever search much.

I found in forum the programmer requirements. I´m studying Assembly and C, again. But if possible, elucidate few locks in my progress and certanily from many many peoples, like me.

How to enable a DEV console ? I found http://www.mpgh.net/forum/356-call-d...r-console.html

But, this code is for inject after compiled in C or to inject in console ?
I try in console, but thinking... No make sense. After all, Is it injected ?

First I search by how to uncompress (decompress) and compress the source.
I found the offzip and packzip, FastFile Tool. I was able to extract the .dat files and I got to extract the code.

1. Copy offzip.exe and packzip.exe to dir
2. In this dir, I put code_pre_gfx_mp.ff file, from BO dir in steamapps.
3. C:\pack>offzip -a -z -15 code_pre_gfx_mp.ff ./ 0

- open input file: code_pre_gfx_mp.ff
- enter in directory: ./
- zip data to check: 32 bytes
- zip windowBits: -15
- seek offset: 0x00000000 (0)

0x0000000e ............... 29051 --> 123104


- 1 valid zip blocks found

I realized that the header was fucked ! Right !?????????

4. Now I have 0000000e.dat in my dir. Use a HEX editor to open it.
U see a code like this


In this Step I could not extract nothing useful (For my brain)

5. I swap for common_mp.ff. Same process
offzip -a -z -15 common_mp.ff ./ 0

Oh a secret here: The size of file is : 57.232.416 bytes but...

Why ?

After that I isolate part of code.
