This is a screen of my actual values hope that it proves that this is working. I made this on 1 Android emulator, 1 iphone 5 iOS 7.1, 1 ipad air 8.3.
After 10 days i'm still able to have my modded values and use them.
To come to your problem here's what i'd suggest you:
-first of all try gameplayer instead of gamegem before say "can someone verify this is working" and see if it works, it's written that the tut is made on gameplayer but IT SHOULD WORK on gamegem due to the fact that is based on the same idea, this means that if you want to do it by yourself you have to use brain or, if you can't manage to do it, follow the steps proved and working.
-The search has to be done as i say, and it's obviously impossible due to logic that those processes number will increase instead of decrease when you follow this procedure, it's a "ricorsive" search on the processes hitted by the changements and every time you do it, the app will find the useless processes, so it sounds strange that they increase instead of decrease.
-I'm not pretending and not asking you to change the value of a int16 that has his max range at (-)32768.
-Dwords and Qwords are used to store money and gems.
-This game"modders" are usersided and not serversided so in some games you may issue a "fake" coin value due to the simple string modification, BUT if you would edit just the string you won't be able to buy anything in game cause the value shown is not a real one. This is not that chase, i'm sorry. Try to do it again, it's written that for ios is required a bit more brain usage than android in order to have this to work.
