Also, it's much easier for you, the human reader, to know what byte 75 means as opposed to bits 1110101, which is what the CPU ultimately understands. Not only is it unwieldy, but with some instructions, the numbers would take up a ridiculous amount of space in the row. Now imagine seeing all binary in that column in OllyDbg, as opposed to hexadecimal. Why not just show the binary numbers directly instead of in hexadecimal? Well, let's look at what 75 09 is in binary: 111010100001001. They are a concise representation of binary sequences that the CPU understands. This is where you'll want to find your way to in your program.ħ5 09 JNZ SHORT ac_clien.00463721: 75 09 and JNZ SHORT ac_clien.00463721 are the same thing. It's where your bytes of interest are stored. Look at the line you have highlighted in the screenshot: 00463716 75 09 JNZ SHORT ac_clien.00463721Ġ0463716: This is a memory address. Let's break down what that means for you. Given that, what you generally need to do is find a direct reference to the memory address that the bytes/instructions of interest are stored in. (If that's what you're thinking, that is I'm making an assumption to craft a reply based on.)įirst of all, what you want to do is luckily very easy (relatively speaking) since all you want to do is directly change bytes. That's an understandable train of thought given your level of experience. Correct me if I'm wrong, but it sounds to me like you're thinking you have to find your way to the beginning of the function so that you can then figure out how far into the function you need to go to change what you want to change. The beginning of the function there doesn't seem to matter in accordance to what you're trying to do.

It sounds to me like your problem is the code in VS, not what you've found through reversing.
Long story short, how do I know the exact start and finish of the function even when nopping gives the result making you think you found it but once compiled you end up finding out it the right place but not the exactly right start/finish.

This is because I don’t know how to determine what is the correct start and end of the function, though nopping a set of addresses still gave me my result but when compiled it will crash. But when I write my hack in Visual Studio and apply the nops, compile and run. When I nop addresses and it seems to be successful giving the results I need like automatic fire and no recoil. But I have a problem I also included a picture for you guy to reference. To find those I just nop one by one and see how it affects. Now I want to look inside that to find automatic shoot and no recoil. I just follow online videos and just guess and play around to see what results I get.Īnyways, I have found the gun function by placing breakpoints. I using Ollydbg to reverse though I have no theoretical understanding of asm at all. I am trying to reverse game called Assault Cube where I am gonna be making game hacks for.
