 Posted: Fri Dec 25, 2009 8:01 pm Post subject: Understanding Hacking |
  |
|
Hi, I am starting to become more interested in the technical aspect of hacking. I would like to learn more about hacking with gamesharks and understanding how and why they work. For example:
800B6F84 0001
This code causes a steady stream of ammo to pour out from the gun and destroys any object you point the gun at. How? I know that the first part of the code is the memory address and the second is the value being written to that address, but that's about it. Also, looking through the GE Documentation I ran across a few pieces of information that I don't know what they are.
What is an offset?
What is a float?
What does 0x18 or anything else in that format mean?
What is a pointer?
Which programming language is the best and where are some good resources to learn programming?

I can help with a few questions...
A float is any number with a fractional part.
Any number with 0x in front of it (ex. 0x14) tells you that the following value is in hex.
A pointer is a memory address which references another. In effect, pointers "point" to other memory locations. |

Ok thanks. But what is an offset? And the code in my first post is for Facility only it says. Why? And I used a Hex editor and looked at the game's code, and I thought that I would be able to find the address in there somewhere, but I can't, so obviously I'm not understanding something. Help?

An offset is just an address in the ROM. The ROM starts at offset 0, and ends at 0xBFFFFF. The 21990 editor is named after the huge compressed data block at offset 0x21990.
GameShark codes modify RAM, not ROM. |

Oh ok. Thanks. Any way to view RAM?

| I think the only N64 emulator with any sort of debugging features (which would include a RAM viewer) is Nemu. If you have a working GameShark and an expansion pak, you're probably better off just using that. |

| Renegade 64 is a very good tool for hacking, can do gameshark like things with emulators. I use that mostly, as well as hex workshop on dumps. |
