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,

Please be more specific.
What is "MP"?
What do you mean under "emulator". You should describe your problem more precisely: what do you want to emulate, why.

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?

You can write proxy and re-rout traffic to a certain address (e.g. local host). Or analyze connection/verification routines in game client for understanding how you can fool it.
# Analyze client
# Analyze packets

So you want to find a way for running illegal game without server checks? If so, I think somewhere in internet you will find what you are looking for

so i've found out the following:

Code:

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?

You can hook send functions (or hook recv/WSARecv/send etc), then get data from packets and modify it.
All information about ip must be in configuration files or maybe hardcoded in client. But changing ip can't help you, 'coz client should receive answer from server and then it should decide to give you access or not
