Its simple flash game Im trying to read value from.
I found my values in three addresses and opened what accesses them
Its same instruction in every address so all info I need comes from it.
See attachment "2.JPG"

This is extra info of that instruction Attachment "3.JPG"
I guess it gives no use.

What I noticed that part of instruction never changes "****F20B - C3 - **" (* - changes). So what methods I should try in order to read these values and have access every time I restart game? Value should be in list/array so it even would be useful to get all information from that instruction.

I already tried pointer scanning but every try led me to 0.

That's not the instruction accessing your address. It's the repe movsb instruction under it. If that's in an implementation of memcpy, you'd be better off backtracing to the caller to avoid having to filter the irrelevant addresses passed to that subroutine.

Are you certain these values are what you want? Does changing them have any effect on the game? If not, it would be easier for you to find some other value.

There is no other addresses which store my needed value. I did scanning many times and only these come up. They show my needed values. "****F20B - C3 - **" always access them.

You didn't give much info on how do you hack it, I mean which process you use
Are your using chrome or Firefox or what ?

Does 'nop'ing this instruction doing anything ?
