I'm hacking the original Assassin's Creed to try making it screenshot friendly (adding some form of free camera or FOV changer).

Right now, I have found the memory location determining field of view. When I alter it, then set it to active, the value is constantly flickering. Skulking and searching through similar problems on the forum suggests that something is writing to the address to change it, and that setting a breakpoint on write should lock it further might work.

I tried this with the game, which promptly froze. Are there other suggestions as to modifying this value and ensuring it stays modified?

If the value is constantly flickering then that means that you didn't find the correct address.
What you found is a temporary scratch space address that is for calculations only for specific occasions.
See if you can find the FOV another way

Example: The game may show a FOV field in degrees between 70 degree to 120 degree. But internally it might be using Rads to store the current POV
This will make that the degree value can be found, as it's used for the display of the gui settings, but it won't have an effect and is read only

Thanks for your suggestion. I understand you have answered this question a lot, and apologize for whittling down your patience.

In my case, I had found the correct FOV altering value, as you predicted. It also flickered, but finding the code writing to it seemed to work, and I could replace it with nothing.
