I'm playing Thief Gold, and to find and lock arrows of various sorts. I found where the amount of arrows is located, it's not a 'green'/static address. So I asked CE to 'find out what accesses this address'. Give myself a couple extra arrows (which works just fine), and fire away, come back to CE. .... Nothing? Nothing accesses that address!? But... it changed! I have fewer arrows! ... What the...!? Tried the DBVM version, too... same result?
How do I proceed from here? Is there anything I can do at this point other than search for that value every level (actually, maybe multiple times a level since it moved)?

so "DBVM Find out what accesses address" didn't find anything ?
Or did you use kernelmode debug with DBVM ?

Check if the physical address changes when the value has changed

(oh yes, enable kernelmode openprocess before opening the process when using "DBVM find out what accesses" )

In Thief Gold, the inventory is a flat array of index-value pairs.
The index determines the type of the item defined for a level (meaning, that the same index might represent a different item on another level).
The value determines how many of them you have.
The order of the pairs is also changing - I did not find any specific logic in it; assume it's randomly populated.

What I did was simple - and usually the simplest things work best.
I hooked the read code and "if the value was more than 1", "but less than 5", I wrote there 5.
That way, no matter how many items/arrows I used, I never ran out but I could always collect more than 5. At the same time, it did not touch items you are supposed to have one of.

This was still true in The New Dark 1.27.

There. I just killed all chances of you having fun hacking it.
Well, good luck!
