PS2DIS Questions Of The Week

[dlevere]

Asked by lowproexplorer

Hey everyone! I'm new to the site and sorta new to programming code. I'm learning, but slowly. I've read over some C++, and also just about every tutorial on PS2DIS codehacking I can find. I have a few questions.

1. I've seen some mention on how to change color codes in games, but they are not very helpful. What would I want to look for as far as a color code? What command would it be with?

2. Is it possible to modify sounds or graphics? If I wanted to use say, engine sounds from one car on another, or swap some graphics, would that be possible?

3. Is there a way to convert hex code to text, like C++ code? Wouldn't it make finding a code slightly easier? I'm sure other programmers must have though about this before, right?

4. Just for my own curiosity, what exactly is on the .bin files on the game disc? Is this where the actual graphics and sounds are located, or are those done in code too? I like to know exactly how the game works, it helps me to understand what I'm actually doing when I'm modifying a line of code.

Thanks in advance for your help....Mike

I keep coming across these label names when I look through the ps2dis on a game:
.Imp
.tex
.vif
.anm
.vag
.irx
Does anyone know the definition of any of these?? I see one name occasionally with 2 or more of these labels and would like to know which one to look for. For example, a single enemy will usually be labeled like this:
demon1.Imp
demon1.tex
demon1.vif
Thank you...

Well, .bin files could be literally anything and everything. Er, well... I'd guess that .tex is a texture, .anm is the motion data for a model, .vag at least on the original playstation was an audio sample. I think .irx is often executable data of some kind (don't hold me to that, heh).

Thing is, hacking by poking about near labels isn't the best idea in the world. Really, I'm very impressed that people have had such good luck with it. Unfortunately most of what I know about PS2 hacking isn't really relevant to this technique...

Thanks, Liquid Man Zero.

.IRX is often a device driver module.

vif im guessing is graphics related since there is a a vif interface on the ps2

Visual InterFace?

Subject: About ps2dis Labels

Some ps2dis labels are hidden, & even hard to understand, like such a label could be about a certain something, but the label ITSELF could be just a munch of numbers or jumbled letters.

So to the best of your knowledge, is there some kind of tool or software I can use with this problem?

You can use CMP's LabelMates, to varying degrees of success:

Other than that, no.

Hello hackers, im an aspiring hacker that wants to understand what im looking at when observing 32bit instructions in the ps2dis. My main problem is with the registers, what are theyre purpose, do they help you find the correct value for a code that he/she is hacking, do registers corrospond with the data, do I need to learn algebra/arithmatic, do they corrospond with the operations such as lui and addui and such ?

Ive been to several tutorials on registers and theyre far too complex for my elementary mind to understand, along with the BIG words that these sites state in theyre tutorials. Im elementary, not a wiz kid (lol) can someone help me understand registers in an elemtary fashion so that my elemtary mind may understand ?
