I was wondering whether anyone could point me in the right direction?

I want to attempt to learn how to create a multi-client. So I need to know what I have to learn and what I should have to do with that knowledge.

If anyone could point me in the direction of a tutorial for creating a multi-client for a MMO. That would be great.

Thank you!

P.S.
I posted this topic in another section of the forums because I wasn't sure which one I should post it in. Sorry.

Ohh and by the way. The game I am trying to make a multi-client for is "Dream Of Mirror Online" GameTribe's version.

Game Site Link:
gametribe[dot]com/gt/domo[dot]do

Come play if you like MMORPGs. It's pretty fun.

It depends on the game itself, not all games use the same method of preventing multiple clients. There are many different methods used to do this. A few would include:

- Checking hPrevInstance at startup in the WinMain function.
- Creating a MuteX thread.
- Checking for a given class / window name.
- Checking for a running service / process.

Find out what happens when you open the second client. Tell us what method the game uses. Patch the code.

Well I am new to it all. The code. I am un-sure what you mean. So I will just post the .exe file.

It is illegal to open more than one client. As it is on most games, but for some reason you are able to open two clients, but no more.

I have uploaded the .exe.

Hope you can help. Very Happy

Its not helping withoutthe other files, besides, its packed.
We can't do anything without other files, you're on your own. (simply search in ollydbg for every call and search for CreateEventA/CreateMutex)
