how can i do this?


Code:
game.dll+AA:     //when you come here
cmp [game.dll+10],1     //check if this value is "1"
jne do_not_change
   *inject this opcode to "game.dll"+CC,  but dont execute or jump here!
   --> nop
   --> nop


do_not_change:
   *inject this opcode to "game.dll"+CC,  but dont execute or jump here!
   mov eax,ecx     //this is orginal opcode

Inject at +cc instead of +aa and put your conditional there instead.

ofc that is a better idea but only if i have one place to inject like in first example. actually there are tens of injection points, and they have to be injected or not injected based on some values. so i need to do this in a clearer way, more practical way.

think about this, what would you do?

Code:
if [game.dll+10] = 1
   if [game.dll+14] = 5
       inject "bla bla..." at "game.dll"+CC
       inject "bla bla..." at "game.dll"+DD
       inject "bla bla..." at "game.dll"+EE
       inject "bla bla..." at "game.dll"+FF
       ...

I told you what I'd do... I'd set a flag and check it at each of the subsequent injection points. It's a clearer, more practical way compared to rewriting substantial executable code each iteration.
