    Hey guys,


    I am trying to hack diamonds in TREASURE DEFENSE using IDA. I got a function called GETDIAMOND. But I don't know which value I can edit. I need your help, guys.

    Here is a picture of the values.

    ive seen alot of your post about editing games, i think you may get a bigger knowledge gain from iver the unreal engine and unity3d engine forums theres alot of people there that make games so they have all done this. try not to mention its for the modding some one elses game . there all pirates so as long as its worded right and not how do i edit some ones elses game. they will add you to live workshops and help you step by step. if they dont and if you dont find what your after on those forums message me and ille show you how it all works

    Ignore the user above me, he clearly has no idea of what you're trying to do.

    - Download the mod here
    - Download the original APK (same version)
    - Extract the .so file of each of them, run them in UltraCompare/Beyond or some other comparing program.
    - Make a note of the offset where something is modified, load both files in IDA and make your way through.
    - You'll be able to see what was modified, and hopefully you learnt something new.

    Compare both .so files in some comparing program to find out the offset where the changes have been made.
    And then, yes, open both in IDA (or just one of them if you're used to the program), search for that offset in Quick Filter and you should come across the function(s) which have been modified. From that point, it should be rather self-explanatory

    Binary. You're just using it to trace the modified offset.

    i tried to check super robot game on IDA...but i didnt found any function like damage,power,life,atk,n such..
    do you think if the game can't be modded?

    the lib i opened was libcocos2dlua.so
    there's just 2 libs libcocos2dlua.so and libnativecrash.so
    no libgame.so there
