So I'm trying to freeze or change the value of a timer in one flash game. I extract the correct address which is the only one corresponding to the timer I see on screen and whenever I change its value, it bounces back to the original value. When I freeze it, however, the game become non responsive and crashes within seconds. Does that mean you can't freeze a timer at all or is there some method? I tried checking what writes to the adress but the "count" column beside no adress was equal to the timer so I don't know if that's a right way to go.

I see, thank you! The timer I'm dealing with here counts the time to the order of milliseconds (cause after you die you get a result like /minutes : /seconds : /milliseconds) - is there some known convention of how such timers are usually stored? Double, int?

As mentioned above from me, I guess it's a double. At least it's a common datatype to store such things like a timer.

Edit:
If you have problems finding the real address go from scratch and start searching with any datatype. Of course this will take alot of research time within the games memory...
Btw you can also try scanning for increase or decrease value (dont change between your scans, since a timer always counts to one direction (up or down with the exception is somehow (e.g. XOR) encrypted)). Just take some time and play around a little. Gather the information you need and then you're ready to manipulate

Mhm, I see, thank you. I tried looking for unknown initial value which increases (the timer here only goes up) in all numeric datatypes but none returned anything with value similar to what the timer is showing. I also tried speedhack and while it does speed up the moves in the game, the timer remains intact. Is there something else that I may try?

Edit: OK, found something! I found three Double type values which are all the same and correspond exactly to the timer in game being in a format [<seconds>,<milliseconds>]. When I freeze all of them, though, nothing happens. I tried looking at what writes into them - each one has only one thing writing to it. After I NOPed the instructions of the two addresses, nothing happened and after I NOPed the last one, the game froze and Firefox asked me if I want to terminate the Flash Player so the game crashed... How can I handle it?

Edit2: Huh, found another record as well - a 4 bytes Int which counts all the milliseconds. Freezing it or NOPing what writes to it (just one instruction again) does nothing either, though...

Oh, I see! Thank you a lot for all the answers, will fiddle around with it and hopefully something finally clicks
