I'm so confused about all these comments. I already said that money is a double type value. So, a table really just needs to be made, to manipulate not only the cash, but the gems, build times, phone storage (for the photos) and girl outfits, etc. But I dont see any way to manipulate it through the game files and such.
The farthest I have seen so far is ah and aj. I think the money values goes down the alphabet.
