I got a unpacked 3.51 client and when i replace one of the codes using ollydbg for the hack code and safe the file, it wont do anything, the client just stays normal, why could this be?
i search for 0045C9F8 |. C74424 20 0B00>MOV DWORD PTR SS:[ESP+20],0B
and replace for 0045C9F8 |. C74424 20 0000>MOV DWORD PTR SS:[ESP+20],00
same with
004A3809 . C74424 2C 0000>MOV DWORD PTR SS:[ESP+2C],00
004A3809 . C74424 2C 0B00>MOV DWORD PTR SS:[ESP+2C],0B
then i save, go test and the client stays normal..
