Hey guys, I am cheating (obviously) and have encountered some problems. I have found the address to store the Kill Count and have discovered that changing that value won't do anything as it is simply a copy of the value that is used to display the UI instead of the actual value. Digging deeper, it would appear that it is calculated and then stored in EAX. I found the instruction that basically moves it into the UI system:

oppw3.exe+FBCAB - 89 43 4C - mov [ebx+4C],eax

Changing the value of EAX to say FFF will make the UI update (one by one) animating to the FFF value. What I'm trying to do next is to find who writes the result to EAX. How can I do that? Is that even the right path to find the true value?

Thanks!

@Gniarf after doing what you suggested, I have found a weird value that's always being increased the same amount as the actual kill count but it is much larger. Looking at what writes to the address, I found the following:

oppw3.exe+203089 - 8B 84 1E C07C0200 - mov eax,[esi+ebx+00027CC0]
oppw3.exe+203090 - 40 - inc eax
oppw3.exe+203091 - 3D A0860100 - cmp eax,000186A0
oppw3.exe+203096 - 0F43 44 24 18 - cmovae eax,[esp+18]
oppw3.exe+20309B - 57 - push edi
oppw3.exe+20309C - 8D 8B D86B0200 - lea ecx,[ebx+00026BD8]
oppw3.exe+2030A2 - 89 84 1E C07C0200 - mov [esi+ebx+00027CC0],eax

The above line mov [esi+ebx+00027CC0],eax essentially copies eax into the value I see and looking above, it is loading it and increasing it by one and then do some compare and move it back in. If I want to make this value large instead of inc eax, what should I do here?

I tried modifying the value at eax but it doesn't seem to do anything. I've tried to change it to 99,999 which is one short of 000186A0 (100,000) and when I see my increase kill count in game, nothing special happened either. I am a bit lost.

Thanks!

Thanks for digging into the game! Basically there is a kill count, and a special move kill count they call "!". I simply want to make it so that I can change these values easily so that I can get a "S" score. I still need to figure out how to do that for the time variable as well.

I did find multiple copies of the variable that holds the kill count value. But changing all of them and go back to the game would result in them reverted to their original value. What's causing this?

EDIT 1: How did you find out they are increasing independently?

So the KO count can be modified like the way you described but the special KO count cannot. I am guessing this value is calculated from another value? What should I do here?
