The ideea of making a server that would "update" GameGuard with old files was commonly used at that time. People simply updated the tutorial and used it on other games that received GameGuard's "blessing". Which brings us to these days. GameGuard uses a module that determines speed of transfer and checks if updates for any of its modules are available.
If yes, the update begins, the modules are re-initialised, then launched and the game starts. Formerly, the tutorial stated that in order to achieve server emulation, one needed to know what GameGuard "tells" the server. In simpler terms, where does GameGuard update from and what is the server's structure. Using a simple firewall, one can find the site, but can't determine the server directory from which GameGuard updates.
For that I think I've heard something about a program called Ethereal which caught packets upon send. But it seems, GameGuard's packets are also encrypted nowadays. Why emulating GameGuard? Why am I saying this? Well, if you are having a dial-up connection and want to play the game, the simple fact of having GameGuard connect to its server will slow you load-up times drasticaly.
It simply froze and I had to wait like 10 minutes only for the update process, let alone re-initialisation. Well, if you want to play GPS from a far country, connection problems appear. Same goes for MapleStory Global. Back in the days when GameGuard would CRC the game's files, my connection got closed upon entering the game. This is the good part of the emulation. Emulating will also allow one user to use obsolete detected hacks, by simply downgrading the protection modules [reverting to old revision files].
So, when the regular modules are at revision 7xx and you are trying to use 4xx ones, your GameGuard. That can be overcome, if you manage to make GameGuard. Knowledge is power In order to achieve emulation, you need to know certain facts of the "trade".
My Questions: How entrenched is GameGuard? Improve this question. Lokked Lokked 45 5 5 bronze badges. Thanks to the 2 answers and some help from another, I was able to bypass GameGuard, discover the crypt routines Blowfish and now I have a stream of unencrypted packets to analyze. Thank you, all! I know this is old, but I just wanted to show my appreciation. Add a comment. Active Oldest Votes. Game hacker here.
Good luck! Improve this answer. That being said some input for general game hacking: Your first step would be to figure out how the anti-cheat is being loaded: is it being streamed from a secure server, is it a DLL which is loaded at runtime, etc.
This is where the actual reversing comes in as the game could use any number of library functions to achieve these tasks. Check the games import table, and function calls for clues. Two common networking libraries are Raknet, and Oodle Network, although it could be any number of other libraries - as a general rule of thumb, if you don't know what a DLL or function does, google it.
Sign up or log in Sign up using Google. If you dont have the game, but have the rom, that is illegal. Its like downloading music on the internet, no one cares anymore A quick google search for "roms" will bring up results I am NOT liable for if you get caught downloading roms seriously, you will never get caught, unless you run to nintendo, sony, or microsoft and show them your downloaded roms.
There are two ways of doing this; the sloppy method, and the neat method The sloppy method consists of dumping all of your roms into one folder. This makes it easy to find the folder, but harder to find the rom depending if you have thousands upon thousands. The neat method is to put all the roms you download in order, by that i mean by system. If your super neat, you could but the GBA roms in a folder abeled "roms" in the files of the emulator itself. Doing so wont effect preformance.
Start the emulator. If you havent installed the emulator idk why your at this step , go to step 2 2. Go to "file", then when the file munu expands, go to "open". This step is the same for almost all emulators 3. Go to the file where you store your roms and select the one you want to play. If you were able to secuessfully load and play something, Congratulations If you were not able to load a rom, you obviously did something wrong and should look over the past couple of steps.
I try to open the game through the emulator and it leaves me with a blank white screen what do i do. Question 11 months ago on Introduction. Tip 1 year ago on Introduction. Anybody Like It? Also when it says view and track your downloads it asks do you wish to open or save the file, and also x86 exe file should i press run? Then i get a message saying windows cannot open the file. Of course that only works for games that aren't 3D. As much as you would like GameGuard to work in Linux, that should not be the goal at all.
On Windows, GameGuard is practically a rootkit and has been known to cause numerous system and application problems, including invalidating the Windows Vista license so that Windows Update no longer detects the machine as a valid Windows machine.
The goal instead should be to get game companies to stop using this product to "protect" their software at their customer's expense. There must be a better way to prevent cheating that doesn't install hidden drivers that inject suspect code into running processes just like a virus , doesn't fail to exit when when the application it protects exits, can be uninstalled by normal means and doesn't potentially break the OS it runs on. Since GameGuard does all that and more, I for one, don't want it to work on Linux I don't even want that kind of thing on my Windows machine, that's why I still run anti-virus and anti-spyware in Windows.
One of the reasons I use Linux is because I don't have to run those products and it is inherently more secure, why in the world would I want to compromise that security by introducing something like GameGuard into my system?
Sure it makes people work a little harder, but cheating is just as prevelent in games that have little to no proper staffing reguardless on if gameguard is preasent or not.
