I'll throw in a little something I've found and also ask for some help on a few things.
First, if you search in only the "Other" memory and and do an exact search for the value of 1 with a type of double you will get ~150 results. Go through the top 15 or so (I do one at a time.) and change the value to 2. When you exit out of the GG screen, if the video doubler pops up with x2 then you did it right and found the correct address. This value does some weird stuff including multiplying your current number of chickens, multiplying the hen house capacity for new purchases, and multiplying your income rate and/or egg rate if you are in a contract. WARNING: Don't go too crazy with this. I used this method to quickly complete all of the challenges and I ended up breaking my game. I can now only do contracts, loading into my home world crashes the app in a few seconds and I'm not sure why.
Now for the things I am trying to figure out.
Is it possible to increase just your shipping rate? Increasing the number of chickens doesn't really do any good after a certain point.
How do you handle searching for extremely large values in the random gifts (such as those in the decillions)?
Also any suggestions for how I could fix my home world without restarting would be great.
