FearLess Cheat Engine

So I'm taking a look (again) at Caribbean Legends, the game that is the successor to Sea Dogs To Each His Own.
Now, the game is mostly if not entirely handled with strings. I'm looking to make something for the game. How should I go about handling them? I can find the values each time without issue, but trying to pointerscan does not yield satisfactory results.
Can anyone enlighten me? Thanks.

Quick google search for the engine lead me to the github for it: [Link]

It's probably old compared to what is actually in the game but the way I would approach it is to first recompile that source and see if I can find the signature for any of the functions that handle the strings you're talking about.
