Ragnarok Online and OllyDBG [C#] - quincytynes - Jan 15, 2015
Hi,
I have plenty of programming experience in C# and recently I have been playing a game (ragnarok online) on a private server. I always liked things like RATS and Obfuscators and all that sort jazz and even wrote a RAT for fun 2 years ago 🎉.
So now I was curious if I could read (not modify) the positions of players / mobs in the game. After some googling I found ollydbg but when I attach ollydbg to the game it crashes ollydbg and the game. Reading memory with C# is going fine but it doesn't provide the tools ollydbg does.
So can anyone give me some pointers on how to continue ? This is my first time using ollydbg, its even my first time trying to do something with memory and processes. This is my first time posting here so if I did something wrong please tell me.
--edit--
I also saw the c# forum but this is not a programming question but more a question related to where I should start with hacking / attaching a memory reader.

Use cheat engine to find where the player positions are stored

That guy has some pretty good videos to get you started

Thanks for the reply, the channel looks like a good source of information for stuff like signature scanning etc. I think the game has some sort of protection against cheat engine because last time I checked I think the game didn't boot when cheat engine was open or shut itself down when cheat engine is opened.
I will verify that in a sec after re-installing the game on a different computer with a vpn on it. I heard they might have ip bans and hardware id bans and I don't want to lock myself out of the game.

You could possible use a virtual machine
I'm not sure if that will actually bypass hardware id bans but it's worth a try

Yeah already thought of that, currently testing out if the game works on a VM because I don't know if the virtual gpu can handle that. Luckily its a old game and supports software rendering so it will probably work.
Also thanks again for the channel it has a ton of good information :) will report back with some more information in a bit.

Yup seems like cheat engine is blocked by the harmony engine, need some sort of bypass for it. Currently writing my own c# program that reads out memory and is scanning for signatures, will report on how that turns out.
