Hello.

İm work on KnightOnline. İ edit your code for knightonline. Remapping succes no error but game is crashing. "unable to start correctly 0x00???" here is code.

ConsolePrint("Waiting for 'KnightOnLine.exe' process..."); int KO_PID = 0; IntPtr bAdress = IntPtr.Zero; while (KO_PID == 0) { Process[] processlist = Process.GetProcesses(); foreach (Process p in processlist) { if (p.ProcessName == "KnightOnLine") { KO_PID = p.Id; bAdress = p.MainModule.BaseAddress; } } } ConsolePrint("'KnightOnLine.exe' found."); IntPtr hProcess = OpenProcess(ProcessAccessFlags.PROCESS_ALL_ACCESS, false, KO_PID); ConsolePrint("Opening process..."); ConsolePrint(bAdress.ToString()); if (hProcess == IntPtr.Zero) { ConsolePrint("Failed on OpenProcess. Handle is invalid.", ConsoleColor.Red); ConsolePrint("Press any key to exit...", ConsoleColor.Yellow); Console.ReadKey(); return; } ConsolePrint("Suspending process..."); NtSuspendProcess(hProcess); ConsolePrint("Process suspended"); IntPtr regionBase = (IntPtr)0x00C70000; IntPtr regionSize = (IntPtr)0x00010000; ConsolePrint("Remapping process.."); bool ok = RemapMemoryRegion(hProcess, regionBase, regionSize.ToInt32(), MemoryProtectionConstraints.PAGE_EXECUTE_READWRITE); ConsolePrint(ok.ToString()); ConsolePrint("Resuming process.."); NtResumeProcess(hProcess); CloseHandle(hProcess); ConsolePrint("Done!", ConsoleColor.Green); ConsolePrint("Press any key to exit...", ConsoleColor.Yellow); Console.ReadKey();

Here is Remap function ;
