What is the most efficient way to find out item hex locations?

[azul120]

I'm trying to pinpoint item hex locations for the Yu-Gi-Oh! DS games in particular, and am wondering what the most efficient means towards this would be. Would the save state method as covered in the RPG hacking document, for instance, be a good place to look?

Here is what I would try: I would look for the price of a few items and then look for a memory region where those numbers occur close to each other.

The most efficient way is probably debugging, though I know some people who swear on being faster with corrupting. However learning debugging won't happen overnight, it comes along with learning basic assembly hacking and is a very advanced topic. I agree that cheat code search style hacking might yield results the fastest - if it's data that can be found with it.

I would try following. Attach a debugger to the game if there is not a build one (TheCheat, Cheat Engine whatever)
When you buy an item you can start an initial unknown search.
after that increase the amount of items by 1 for example then decrease it, increase it until you have only 1-2 results left.
Now it depends on luck but often the hex of an item is right after or before the actual amount you are buying.
You can try that.
