Hi,

I "hacked" like 2 games with CE by now. But at my current project, which isn't a game, something weird is happening.

I need to freeze the time that is limiting the current session. Means:
Starting the program also starts a countdown timer. If the timer equals 00:00
the session expires and you have to restart the program. We wrote a little prog that is restarting the other prog in certain intervals. But freezing the timer is much more efficient.

I found the address and the time is stored as a 4 Byte value.
Actually the time is mesaured in ms. As expected it is a dynamic address.
But it is more than only dynamic. While trying to find the static address suddenly the dynamic address changed. At first i wanted to know if that is common nowadays.

And may you help me finding the static address?
"What writes to this address" shows me 1 line of assembler code:
mov [ecx+ebx], eax // where ebx seems always to be 10
When i start a new scan to look up which addresses hold ecx I get like 288 hits. Do I have to examine each address to find the static pointer or is there a better method?

Edit:
I found an address (luckily) that is changing its value very often. Sometimes it contains the time. I am so confused now Very Happy

A non-static address that changes is often the result of something called 'DMA'. (Dynamic memory allocation.) Or possibly even 'code-shifting'. There are tutorials on this forum that cover both subjects on how to handle them.
