Hello, I have been using GG on some easy, small apps for about two weeks now just to learn how it works. A few days ago I tried editing my gold in PD (Portable Dungeon II). First I used the exact search and the encrypted exact search to find the gold. After doing that I end up with these values; Due to problems that I will talk about later I switched to fuzzy search and found these values; With fuzzy search, I could only narrow the results down to 488 so I looked through all the numbers until I found values that seemed to be of use. Now my problem is that every time I try to edit my coins and go back to the game I see the number has changed to what I want but ends up going back to what I had before. I noticed that the searched always come up with multiple value types with the same number and an XOR value. With that in mind, I tried editing all the values (W,B,D and Q) at the same time thinking that having all of them change would possibly take out the possibility of the app checking back up values to reset itself. With all this being said I have a few questions: 1) How is it possible for values to have the same address? 2) Are there some techniques that developers use to make sure values stay unmodified? 3) What is the use of XOR values? I have already read a lot about XOR encryption/decryption and understand it but when I find XOR values in searches I am never sure how or if I can use them to assist me in cracking a game. Any information to point me in the right direction would be awesome. Thanks
