To create a game where others can join you have to create a session. When you create a session, a code is generated and displayed as `#### #### #### ####` where `#` is hex numbers.

There's an option in-game to show/hide the information, which makes the string swap to `**** **** **** ****` instead.

It's easy to find the string as it's very unique, however, every time I restart the game the address changes. And the value I'm finding is only the display value, if it's hidden, I cannot find the session id.

My end goal is to find the session id in memory without having to talk to the NPC so I can display it to the user and allow them to copy & paste the code without the need to use OCR.

Relevant findings:

Code that swaps between `****` and `####`


Code that calls the swap function


String display memory


Any ideas on how I can find the session code before it's displayed? How is it stored in memory? Concatenated? Different format? Can I find it every time the game restarts?[/img]

Code that swaps between `****` and `####` - that's just a memcpy routine, or something analogous to it.

Code that calls the swap function - not enough information to figure out what's going on. Maybe that `test r12b,r12b` instruction checks if it's displayed as `****` or `####`, but that's naively hopeful. Everything below that in the image is just string / vector operations. Everything above that... no idea.

I guess I don't really know what I'm doing.

I managed to get a pointer



But this only shows the value if I talk to the NPC and unhide the info. I wish I could get the value that's stored somewhere else.
