 Posted: Wed Aug 15, 2007 1:13 am Post subject: PS2DIS experts? |
 |
|
Are there any ps2dis experts here? we need urgent help on something!
Here we go!
Im trying with a friend, to edit the memory of our test psp application , so we can get a better understanding of how memory works.
Here's what we have , and our progress:
we have a simple eboot , that does this:
| Quote: |
int somevariable=0;
while (inloop) {
CLEAR;
//track changes
printf("PRESS X/O TO INCREASE/DECREASE THE VARIABLE ");
switch(somevariable)
{
case 0: THE_MESSAGE="DEFAULT!";break;
case 650: THE_MESSAGE="Hey , why you edited my data?";break;
case 445:THE_MESSAGE="STOP IT!";break;
}
}
|
Now , with cheat master we're able to locate & edit the address.
All fine here.
But guess what happens if we edit the code a little:
| Quote: |
int somevariable=0;
|
to
| Quote: |
int *somevariable= new int;
|
What actually happens , is , that the address is always different on each run.
We heard that we have to use PS2dis(so we can find the secret pointer) , and we tried to learn...but we need a little help.
We searched for the actual variable name (which is MANA_POINTS) , but the address is fake.
Can someone expert/experienced help us?
thanks. |

| New allocates memory at runtime. There's no reason the address would be the same each time. |

Yes , we know it , but let me explain why were doing it that way.
Our target , is to create CHEATS for our favorite games that we own& share them to the public.
Some games allocate memory DYNAMICALLY (people call them "dma games"), and you have to search all the time for addresses.
There is a reason that we call our demo-app "D.M.A EMULATOR"...
So , can someone help us with some tips on how to locate the wanted address? |
