 |
|
Well, I have a question for you. Recently I decided to hack a game, on this game you have lives and I want to make a hack on this. I found the addres where the lives are stored, so I can change the value manually and it works fine 
Then I decided to make an AA script, the original code is this
| Code: | alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
newmem:
originalcode:
add dword ptr [esi+000000A0],FF //original code
exit:
jmp returnhere
"GeometryWars.exe"+24AD3:
jmp newmem
nop
nop
returnhere: |
The only way that I found to make a "work" AA script is building full of nop's:
| Code: | alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
newmem:
originalcode: //full nop's to prevent decrease lives
nop
nop
nop
nop
nop
exit:
jmp returnhere
"GeometryWars.exe"+24AD3:
jmp newmem
returnhere: |
This works fine, but I think this is not the best way to do it. Can someone help me?
Thanks

mov [esi+000000A0],x
x can be whatever number that you want to set for health.
If there is no other code that would change the health, nop will work perfectly, doesn't matter that it is "elegant" or not.

why do you even alloc ?
| Code: | [ENABLE]
"GeometryWars.exe"+24AD3:
db 90 90 90 90 90 90 90
// since the code add dword ptr [esi+000000A0],FF is 7 bytes long we replace with 7 nops
// nop or db 90 is the same thing
[DISABLE]
"GeometryWars.exe"+24AD3:
add dword ptr [esi+000000A0],FF |
