Help/Support Search for the necessary structure in IDA(IOS & Android)

Archipunchi · February 19, 2023

Good evening, friends. I explain the situation. I hacked a couple of Bullet Echo game functions, but on Android, using GameGuardian, because the functions from the iOS version of the game were obfuscated, I couldn't find anything useful there. Thanks to GG and my perseverance, I was able to crack 2 very serious functions, moreover, I was able to find lines of code in IDA, from the Android version of the game. I put labels on them so as not to lose them, on all memory addresses. The only question was how I would transfer these memory addresses to the iOS version of the game, again using IDA. In short, I imposed IDA (Android) on IDA (iOS) versions of the game, to analyze and find the right one on the iOS version, since I am an Apple user. I managed to patch the zoom function, but I have problems with the second function, I can't find some memory addresses comparing Android and iOS. There are big differences in processor architectures in IDA. The code is different, the constants are different. Roughly speaking, almost everything is different. Are there those who can tell me how I can superimpose android on ios, find the memory addresses that I have already found in IDA (Android), how can I find the exact addresses in the iOS structure? Thx

Hello, I am not aware there are magic to port of Android offset to iOS.

Is it a Unity game? Do you familiar with Il2cpp dumper? You can actually get back the original function name of a Unity game in IDA with help of Il2cpp dumper.

You may refer to Stage 2 and Stage 6 of my tutorial here to understand a bit more.

This is where you’d need to learn strings.

Can you elaborate more on how it helps to port Android hack to iOS? Love to learn more.

I'll see what's inside, but it's not Unity, it's a server game

I pumped my IDA travel skills and found all the memory addresses for Bullet Echo with incredible actions)

In total, I have:

A map with light

an enlarged view from above (zoom)

a full vision of opponents in the grass

360 flashlight.

Maybe I'll post a mod menu a week before the next update😅 I don't want views from the developers
