Assembly dll editing memory editing

[bepai]

Hello to all,

There's a section of memory which is being edited by one of two dll's when the relavent dll is loaded. I know what the code in the section of memory is and what the code gets changed to. What I dont know, and my question, is how to find the section of the dll which makes this edit. What do I look for? code in assembly.

Thanks

Use a debugger that allows you to put a watchpoint on that location in memory and see what code executes at the time the memory gets edited.

I'm using ollydbg do you know if it has this feature? there is "watches" but this is for expressions?
