[Release] Yu-Gi-Oh! Master Duel PVP Surrender Opponent

[traumspieler]

As the title says.
Konami screwed up big time, you can make the opponent give up!
Only works on your own turn, then simply activate "surrender opponent", confirm, opponent surrenders.

In addition, a "No Surrender" feature is built in, which allows to surrender at any time, but the surrender is not counted, the game has virtually never taken place (for you).

Information:
directx 11 present gets hooked & some overlays can make the cheat not show up.
For example, if you are using RivaTuner, you must disable RivaTuner for Master Duel.

You could make your own dll with the following functions:

How it works:

void PVP_ComDoCommand(int player, int position, int index, int commandId)
{
    uintptr_t address = gameAssembly + 0x62BC00; //void YgomGame.Duel.Engine.PVP_ComDoCommand(int player, int position, int index, int commandId)
 
    return ((void (*)(int, int, int, int))address)(player, position, index, commandId);
}
 
bool IsMyself(int player)
{
    uintptr_t address = gameAssembly + 0x627890; //bool YgomGame.Duel.Engine.IsMyself(int player)
 
    return ((bool (*)(int))address)(player);
}

then just call

//send surrender command with the id of the opponent
if (IsMyself(0)) PVP_ComDoCommand(1, 0, 0, 11);
else PVP_ComDoCommand(0, 0, 0, 11);
std::cout << "opponent surrendering..\n";

in your main loop

Because many of you are reporting it doesn't work, my signature obviously bricked hard.
In the following lines I will provide a full noob proof how to compile your own surrender .dll tutorial.

First step: download and install visual studio (desktop development with c++).
Create a new project, search for the dll template (just search for dll and select Dynamic-Link Library with the c++, windows and library tags.
Change your build configuration to Release and x64 (the project will start in Debug x86).
Then right click on your project in the solution explorer (right side), select Properties -> C/C++ -> Precompiled Headers -> change precompiled header to "Not Using Precompiled Headers"

Select everything in your dllmain.cpp and replace it with the following code:

#include <Windows.h>
#include <iostream>
 
HINSTANCE dllHandle;
uintptr_t gameAssembly;
FILE* stream;
 
void PVP_ComDoCommand(int player, int position, int index, int commandId)
{
	uintptr_t address = gameAssembly + 0x62BC00; //void YgomGame.Duel.Engine.PVP_ComDoCommand(int player, int position, int index, int commandId)
 
	return ((void (*)(int, int, int, int))address)(player, position, index, commandId);
}
 
bool IsMyself(int player)
{
	uintptr_t address = gameAssembly + 0x627890; //bool YgomGame.Duel.Engine.IsMyself(int player)
 
	return ((bool (*)(int))address)(player);
}
 
DWORD exit(std::string output = "\nunloading..\n")
{
	std::cout << output << std::endl;
	Sleep(2000);
	fclose(stream);
	FreeConsole();
	FreeLibraryAndExitThread(dllHandle, 0);
	return NULL;
}
 
DWORD WINAPI attach()
{
	AllocConsole();
	freopen_s(&stream, "CONOUT$", "w", stdout);
 
	//get GameAssembly.dll address, if it doesn't even exist -> exit
	gameAssembly = (uintptr_t)GetModuleHandle(L"GameAssembly.dll");
	if (!gameAssembly) exit("GameAssembly.dll not found\n");
 
	//output text
	std::cout << "**can only be activated on your own turn**\n\n";
	std::cout << "'F1' = surrender opponent\n";
	std::cout << "'F2' = unload tool\n\n";
 
 
	//cheat loop
	while (true) {
 
		//surrender hotkey
		if (GetAsyncKeyState(VK_F1) & 1)
		{
			//send surrender command with the id of the opponent
			if (IsMyself(0)) PVP_ComDoCommand(1, 0, 0, 11);
			else PVP_ComDoCommand(0, 0, 0, 11);
			std::cout << "opponent surrendering..\n";
		}
 
		//unload hotkey
		if (GetAsyncKeyState(VK_F2) & 1) exit();
 
		Sleep(1);
	}
 
	return NULL;
}
 
BOOL APIENTRY DllMain(HMODULE hModule, DWORD reason_for_call, LPVOID lpResreved)
{
	switch (reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
		dllHandle = hModule;
		DisableThreadLibraryCalls(hModule);
		CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)attach, NULL, NULL, NULL);
		break;
	}
	return TRUE;
}

You should now be able to build the dll. If you get some errors feel free to contact me, I'll try to help.
You can inject the dll with pretty much any injector, but I would recommend Xenos for you (I know this works and you can find the download here on UC).

If this doesn't work for you (if nothing shows up on your screen after you pressed 'F1' on your own turn), it means that the offsets needs to be updated.
I will explain an easy way on how to get the offsets, that everyone should be able to follow. All you need is cheat engine.

How to update surrender offsets:

Open cheat engine and attach to masterduel.exe. A new menu should appear at the top, labeled "Mono". Click on it and select ".Net Info".
A new window will pop up.
On the left side select "Assembly-CSharp.dll", in the "Classes" window, search for "duel.engine" and select "YgomGame.Duel.Engine".
At the bottom right side there will be a new window with all methods that are in that class. Scroll through the list and search for "PVP_ComDoCommand".
Double click that entry. The disassembler should now show up and it should look like this:
https://prnt.sc/26qewdx
Write down the address one instruction above the PVP_ComDoCommand function and add 1 to it.
We have to do this because cheat engine doesn't tell us the address, it just tells us the function name (if anyone knows how to get CE to display the address instead of the name, I would appreciate a little tip ).
Now do the same with the IsMyself() function. Its also in the Engine class.

All you have to do now is change the offets in your dllmain for the given functions (and dont forget to add the 1!).

Thanks for your sharing! And I would like to ask is it possible to modify data in a PVP duel such as the number of trap cards being activated?t

[freestylez01]

Do you have a video to show it?

Yeah, but doesn't show the "new" surrender-doesn't-count feature & I'm too lazy to make a new video

Thanks a lot for sharing this, its a great way to exploit the game and rank up easily

I figure out how to make it work, just need to add some more work, thanks PAL it work so well.

[ZeedKaiser]

didn't work for me, instead of green mine all red menu..can u help me great sir?

[ztrickiv14]

only function that works seems to be hide and unload tool

Nothing happens when I try to launch it (maybe because I'm doing it on a VM but not sure) how did you make it work?

[fickoeizy]

i follow the video and its not working

[mbakamj91]

pretty sure its been patched

How did you manage to make it work? I also just get the text in red and nothing works except for hide and unload.

[BullyWiiPlaza]

It's not working. What's the usage guide? After launching the EXE nothing happens. Pressing F1, F2 etc. also does nothing. The file is VMProtected so I can't tell what it does, so is it a troll? I think the surrender mod isn't even possible.

Ok it injects normally outside of VM but the surrender option doesn't work, only "hide cheat" and "unload" works

Is the surrender opponent (f2) hotkey also red?
It is possible that from region to region the offsets are different.
For this I actually had a pattern scanner built in, unfortunately I don't know il2cpp very well and therefore use the classic native game hacking methods.

I will update this post with an guide on how to do it yourself and which function gets exploited.

Do you have rivatuner or msi afterburner installed? Or the discord overlay?
If rivatuner, set application detection level to none and restart the game

Should work on a vm, I'm also using it on a KVM, just checked with the official download and it works for me

[Friremwen23]

thank you

[SogenmuZero]

also having trouble with activating f2, unload and hide/display work. f2 stays red

[maule2]

Work Perfectly, nice Job traumspieler
