Hello RageZone!

Hey buddy, here's a tutorial for you!

Step 1: Add this code to detect if client is running already
Step 2: Only one process will run!

C++:

#include <windows.h>
#include <stdio.h>

int main()
{
	CreateMutex(NULL, 0, "MYMUTEX12345");
	if( GetLastError() == ERROR_ALREADY_EXISTS )
	{
	    MessageBox(0, "Error; process is already running.", 0, 0);
	    return 1;
	}

	printf("Press F5 to exit loop.");

	while( !GetAsyncKeyState(VK_F5) ) Sleep(500);

	return 0;
}

It works the same way in any language, just import CreateMutex and GetLastError! Enjoy

Working on making an emulator tutorial, it's complicated to explain but I will try my best when I have some free time
