I guess for me, its update GG. I use Cheat engine on the PC all the time and comparing the two, GG is very limited in what it can accomplish. I don't know Android code, but I do know that GG cannot find "changeable" values for most games.
Take Final Fantasy 5 and 6, it can't change the EXP values, but it can with FF4. I dono, its just what I'm seeing.
:edit:
Figured out how to get the Fuzzy Search to work in FF5 for EXP value change with 4 bytes.
