a game has always libs, but when a game has .dlls in assets/... then you mod the .dlls.
thank you, need some advice :
1. tried to dump with Il2CppDumper i got dummy dll which contain assembly-csharp.dll but if decompile with apktools no assembly-csharp. so I modified libil2cpp instead. is that the correct way?
2. after I modified libil2cpp, I run the game but stuck in loading page. is there any way to debug running game ?
thanks again for your help
Could you please rephrase your 1st point?
2: The offset you modified is not what you're looking for, or maybe the opcode you placed in it doesn't work. And yes, you can debug the library using IDA.
thank you, im able to mod it after i check on arm version.
One more question, any tutorial to make sure we will not get banned by game dev?
Just test. Use your own mod, and see how far can you get. You could try looking for integrity checks in the .smali or functions inside the il2cpp that might detect abnormal behaviours for the game.
thank you for your help, absolutely will do it :)
sorry this is one last question. I was able to modify and change value in hex or change status by true/false.
but what if I would like to add function into existing ?
this is what i found inside .dll what i believe func to send card
by default this will send 1 card in one time, and I would like to modify the func so I can send 100 cards in one time. any advice on how to add function in hex?
Sorry if I asked too much, and really appreciate your help
Size of the .so should not be changed, that would mess everything, since branches are done with pointer arithmetics on the static offsets. Adding an extra instruction means displacing the others by 2 or 4 bytes, all those branches from before the addition to after addition or the reverse will be broken.
Yo can still edit existing instructions, and make some interesting stuff in there as long as your new func is equal or shorter in size.
You will have to analyze that function using IDA, and see how it works. It's a void function, which means there's no "final value" coming from it. All the important changes will be made inside the functions, some values will be stored or loaded, etc. I believe function will begin with a "push {x, y, z...}" instruction.
Try adding pop {x, y, z...} bx lr in offset following the push, and see what happens.
There are several layers of knowledge on modding, but something is certain:
Some games requiere some time to mod, the time IDA needs to disassemble the lib.
And also, figuring out what to mod.
Allowing everybody to learn how to mod, leaves the pros with more time to mod the hard ones, since the easy ones can be taken by trainees.
