Thread: Beginner question

I'm a beginner hacker/programmer my question for you was the following:

I want to make a emulator for the new Black ops: my idea was the MP isn't working right now and i wanted to know if it is possible to make it so it reverses the address that it connects to towards my network ( local play ) and saying that it should connect to the lobby.

What should i learn to create something like this, or is it not possible?

Thanks in advance,

MP = MultiPlayer the current Black Ops system you can't even play local because it connects to their server and checks if your game is legal if it isn't it returns a failed connection value.

Emulator = some kind of patch you have to run to fool the client.

And my question was: if we can redirect the connection it makes to our local network so that it connects to local lobby would that be possible and what should be learned to achieve this kind of things like e.g reverse engineering or something else?

so i've found out the following:

Code:

0000  00 1b fc 42 d1 a9 00 1a  92 db 89 46 08 00 45 00   ...B.... ...F..E.
0010  00 48 54 2f 00 00 80 11  00 00 c0 a8 01 07 c0 a8   .HT/.... ........
0020  01 01 d9 86 00 35 00 34  83 9e 46 dd 01 00 00 01   .....5.4 ..F.....
0030  00 00 00 00 00 00 09 63  6f 64 37 2d 73 74 75 6e   .......c od7-stun
0040  02 75 73 09 64 65 6d 6f  6e 77 61 72 65 03 6e 65   .us.demo nware.ne
0050  74 00 00 01 00 01                                  t.....

The following is the queries = the ip it connects to which should be fooled

Code:

09 63  6f 64 37 2d 73 74 75 6e   .......c od7-stun
0040  02 75 73 09 64 65 6d 6f  6e 77 61 72 65 03 6e 65   .us.demo nware.ne
0050  74 00 00 01 00 01

To make something to fool it would need intermediate C language understanding right?

And how does the client knows what ip to connect to it must be saved in one of the client files right? shouldn't it be possible to change that ip in the client files?
