Hi i am new to auto assemble pls help me pls as no one explained( i think so) why/how should i do this 3 things below..

1. why will messing around with code that decreases/increases ur health in an online game server sided? lets take maple for example...isnt it calculated by the server? why when we mess with THE CODE/MEMORY, it actually DOES DO god mode? isnt it client sided? im confused X_X

2. when we alloac unused memory to something..how do i know how much KB i need? and is it confirm that EVERY game has got unused memories??

3. why is it that sometimes when i do code injection on an address, it will have one command line...and when i do it on others..it will have about 3? is it link together or something?? ill show a picture...its so confusing X_X

Because when you jump out from gamecode, a standard jump will take 5 bytes. 5 bytes will destroy that dec edx command as it is only 1 byte in length. It will also take the mov eax,ebx and call 4f316c as they are 'eaten-into' so-to-speak. Whereas that first example you gave... the opcode has enough bytes (6), so a jump can be created and the jump balanced with a NOP. It doesn't usually matter what you destroy on the proviso that you re-create the instructions in the code-cave before returning back Wink

Ok, one, what I think you mean is "why when I change my health does it not work on online games?". And the answer to that is that the variable is known as 'server-sided', 'sync'ed' or similar. Basically the server has the last say, and it will override the value you hold on the client, or kick/ban you. Depends on the game itself and any memory protection it might have.

And two, allo and dealloc just assign memory for your use, and then strips it away when you don't need it anymore. Its space you use for your code-injection, and is known as a cave. Strictly speaking you don't need to allocate anything, as there is always free space within a game's modules that you can use for the same purpose.

As for the size of these allocations, it depends on how much your going to use. Just leaving it at the default of 2kb (2048 bytes) is more than enough for most people. If you however you are using the same area for multiple, sizeable injections, then that would warrant an increase.

Good enough? Razz

If you study assembly long enough you can pretty much tell what all the common appearances of the opcodes with be. Moving the value in an address like that into a 32-bit register is 6-bytes for example Wink

DarkArc, I suggest you read the thread again. He was talking about the number of bytes in an opcode, not how large data-types are for variables. Also, I hope your not implying that I simply 'found that info anywhere'. Despite what people may think, some of us do actually half-know stuff and work hard.
