Orpheu replace variable
I want to replace variable value in function for example
Code:
signed int __cdecl SV_CheckKeyInfo(int a1, int a2, int a3, int a4, int a5, char *s) |
Re: Orpheu replace variable
- Hook Q_atoi and change the returned value.
- Why 5 ? Returning 5 whatever the checks, I guess, hooking SV_CheckKeyInfo and returning such value would work. If hookable. |
Re: Orpheu replace variable
- how ?
- it's just for example :) |
Re: Orpheu replace variable
How ? You don't know how to make signature file ?
|
Re: Orpheu replace variable
but Q_atoi is not function on engine or mod , or maybe I'm blind :D
|
Re: Orpheu replace variable
If it's used into the engine library, it means, it's referenced there and it is, just checked.

Re: Orpheu replace variable
change value is easy, but could u tell what exactly you are going to do?
|
Re: Orpheu replace variable
I wana just learn how to do that.
how to change code in function no just return but set that some of the code is skipped , changing values of variables and others that give us a powerful capabilities |
Re: Orpheu replace variable
so, this is not a particular hacking demand. You just want to know how to patch memory?
well, then you need to know at least some asm operation first. changing value is the easiest thing of patching memory, espeically a const. sorry can't give u example with orpheu, cause I never use that module before. I suggest u coding a module for hacking memory, that's an easy way to do that. |
Re: Orpheu replace variable
Ok I will read about it :)
maybe someone give example in orpheu , also how to check variable address in IDA if I have address I could use OrpheuMemoryReplaceAtAddress some of the code is skipped - it can be done with memory patch ? or with orpheu ? |
