Hello all,

I was wondering if anyone knows where in the game the code for the simulant AI is located? I wanted to toy around with it to see what happens. I guess to experiment . Anyone know if it's possible or where it is?

[SubDrag]

I must admit, not sure. I think the best way to hack, is to breakpoint on the type of simulant set (of the settings) - CheetahSim, etc, and see what switch statement (set of TLB jump registers) it has. Shouldn't be too hard to locate those routines that at least deal with those special ones - and maybe lead to AI in general.

[kariko]

Hmm...um..what does that mean exactly?

Well I used the magic of Google to learn what a breakpoint is, and now I realize I've done that before using the console gameshark (I think? It's where the game paused and you could see the code all over the screen right?) but is it possible to do that in an emulator, specifically PJ64? and if not, where can I go about maybe...looking at the code and just "adding cheats" to replace specific lines?

I think I need to learn more about the actual game code and how it works because I'm looking at the preset codes and it doesn't really help... but would my idea maybe work? Sorry for so many questions, I feel really excited to try it, I just don't know where to start.

[SubDrag]

You should use the nemu emulator, it lets you breakpoint, and see registers and memory.

[kariko]

Hmm...is there someplace where I can learn about the N64 code? There's so much numbers and letters and things, I'm afraid I won't be able to do this very well with my current knowledge of it, which isn't much. I downloaded Nemu64 and I'm looking at the code but I'm unsure what I'm looking at/doing, hehe.

EDIT: I think I might not be able to do this.

[SubDrag]

Yeah you don't get a nice C++ set of functions, it's mips assembly code.

[kariko]

Ah crap. I'm going to learn C++ soon, but I know hardly anything about it at the moment. And I assume mips assembly is even harder then, for me. Ah well. I can still toy around with the Editor. Maybe after I learn more about C++ and programming in general I'll have a better understanding.

[acceptable67]

Yeah, it is really confusing stuff. Well, breakpointing atleast to find addresses/offsets. I personally don't even know how to do it yet... SubDrag just assumes you know all

You should have a lot of background knowledge about the game and how it functions before ever diving into something like this.

See hacking tutorials at therwp.com MIPS it's good to know C++ well, so you know how it goes where.

To be honest, I'd imagine that the artificial intelligence routines are not going to be something a new(-ish) programmer would find easy to Understand. Especially on the N64, and not just because the N64 is (so I've heard) complicated to program, but because the AI routines will be programmed as efficiently (in memory terms) as possible, to save space on the cartridge and in the N64's memory, which will make the routines even harder for a beginner to understand.

I really *really* wish Rare would release the source code to their games, as id Software, 3D Realms, and very few others have done. Probably never happen, but we can dream.
