Cómo jugar online a CoD4 y evitar el ban de Punkbuster

Well, I've seen that, after downloading the Call of Duty 4: Modern Warfare due to post Lomotek (link) you had some problems playing online, and especially to prevent PunkBuster you ban the user to have a non original key, I'll hang it information I have obtained myself after conducting several tests, I hope that helps you:
To begin, we must do several things:
1-Download the game from the post of Lomotek here.
2-Install the game as Lomotek tells us both as in the video post: First install the game image, then upgrade to version 1.7 patch and then apply the crack (you should not ask for serial).
(It is important that respeteis this order, because if, for example, aplicais the crack before the patch, the latter, it's official, I detect the installed game as non-genuine, and you must reinstall the game to update.)
3-Apply the same solution that has been published in various forums, including this one, which theoretically runs only on Windows, only with some "adaptation", I tell you, the solution for Windows is:
This is the solution that is for windows
Message is generated *** *** WARNING: This server it is banned by Punkbuster
Note: This change does not adversely affect those of you with the original game.
This causes an uncomfortable messages generator as stated above, and the game locked up while we're on a server with a huge lag.
Always remember to Tools / Folder Options / (View tab) and point to see the file extensions and the option to show hidden files.
Enter the folder Call of Duty 4 - Modern Warfare / p b. The solution to the problem, and more effective is that he proposes Cpt_ThUNDER:
1) Open the lock application notes
2) write anything. Example: "Stop bothering me."
3) We keep as ... and we as the file name: pbns_c.dat.
4) We note the file, right click mouse / Properties
5) Down in attributes: read-only note.
6) Go to your pb folder of our call of duty 4
7) Copy the file you just created overwriting the existing one. We must do exactly what the problem is that the naked eye can not find the file or folder that you indicated, but it is very easy to find:
1.Nos go to the Applications folder and look for our CoD, which normally tends to be a folder containing launchers and CoD4 CoD4 Multiplayer, plus several folders. Right-clicking on the icon of CoD4 and give it to "Show Package Conetnido" ... et voilà, the Contents folder and find the folder "Pb".
2-We went and found the file you need, pbns_c.dat.
3-Now we can either create a new file to replace or modify the original directory (Copy that to the desktop before, just in case), to modify simply click the right button and check "Open With" and select TextEdit. Write anything and kept until accepting the option to replace. Done this, do the equivalent of windows "read only", ie right click> get information and at the end of the "general" check "blocked" and enter the administrator password if you request it.
4-The difference with windows is that you must repeat the process with the multiplayer, is that you ought to perform the operation on both executable dle game, both single and in multiplayer.
Once this is done you should be able to play online without any problem, but it is important that you have in mind a few things:
"As the game cracked, you can only play on cracked servers and the server you will find in the menu of the game itself can not be cracked, because that is the game servers from official sources only accept original copies of the game (and identify whether those copies are original or not part of the work of PunkBuster, the utility that bans you and you slow the game), therefore, unless rare exceptions, you can never access any server from those contained in their own menu the game without the original game. That is the reason why many you find yourself with little message "Key in use" when entering a server, you are entering an official server.
"To find cracked servers is easy, there are thousands on the Internet, and with the help of St. Google, you will find those who are searching writing texts like "cod4 cracked server" and you will also find many sites with full lists, which I often use is to ********* (link) that is the most complete, updated and easy to use (you can sort the list by country, rating, number of players ...).
"To assure that all this work, we recommend disabling the PunkBuster from the menu of options> multiplayer options.
"For those who do not know how to get into the cracked servers, there are two ways:
OPTION A)
1-Copy the IP of the server, which should be of 85.223.64.2:28960.
2-Start the game (multiplayer).
3-In the main menu, press "º ª \", which is below the Esc
4-In the top of the screen we will get a shaded band (console), which surely the symbol "º", we should delete. (This is the reason why many do not operate ip)
5 - write "connect", a space and copy the IP, for example:
85.223.64.2:28960 connect
Be sure that it is just like the example above, and do not you forget to delete the symbol, because if not, it will be introducing this:
No connect 85.223.64.2:28960
And just close the console, it will not recognize the command.
After entering the command correctly, enter pulsáis and play.
OPTION B:
Automatically connect to the servers using specific programs. There are several, for Mac and PC, but personally I think the best is XFire, and the version for Mac is iFire (link)
You ought to download, install and, once started you ought to start session (you need to create an account at XFire, here)
Once this is done, and the program open, you go for example to the list and pulsáis *********, the xfire icon, that is, the 3 icons you see on the left name server, the first from the left.
IFire automatically start the game and connected to the selected server.
Personally I recommend the option of iFire, is infinitely more comfortable, because you have to do shirk on hand a list of servers that you like and stuff, just abris page from the list of servers, which also is updated automatically .
I hope that despite the brick, I serve as a support to you had a problem, and for any doubt, you only have to expose it in this post.
Regards and see you on the battlefield!
