How to Deobfuscate a game that has Il2Cpp ?

[NameLord]

I tried to deobfuscate a game that has Il2cpp with

• il2Cpp Dumper [extract all the dlls from UnityPlayer.dll]

• .Net Reflector 10.2 [Extract all the C# code from dlls]

• De4Dot [Deobfuscator for all the C# ] idk if this works

but for some reason it didn't worked to deobfuscate it.... so i think this is my last chance here.

is there a way to deobfuscate a game that has [Obfuscator And Il2Cpp ] ?

You need to learn ASM and use a tool like IDA-Pro or ghidra.

So is there a way? because im not willing to try if it doesn't.. like. i don't want to waste time and in the final not to work.

Yeah, although it will be difficult.

But there is software that can do that? or? sorry for late comment

You would need to use a tool like IDA or ghidra, These tools are far from perfect though and they have a very steep learning curve.

You can use Perfare's IL2CPP dumper, which will dump the symbols and metadata (which is extremely useful, when you have to RE) and then use ida and run the provided script by the dumper which will name all your subroutines, after that you have to reverse engineer the actual implementations yourself.

yeah there's no deobfuscation, it's just not C# anymore

technically its not obfuscated but rather compiled to native instead of managed .net
and most game dev studios do it when they want to increase performance, the amount of cheaters in their game will probably be the same its not any harder than C# decompilation but just requires more time

[NameLord]

Is De4Dot Usefull for deobfuscation?
and .Net reflector?

Ok i need a little help with Ghidra....
If you have discord add me

If not ... then never mind.

[xXTurnerLP]

For C# decompilation i would recommend dnSpy
And for native dissasembly I would recommend IDA, the free version doesnt have decompiler so you will only see the assembly, if you really want the decompiler you have to buy it.

Details

Or use alternative methods

Like downloading a cracked version of IDA Pro

I would like more easyer talking on discord

Are cheaters using GitHub now? interesting, no one's going to help u btw figure it out on your own.

There are many reasons to deobfuscate a game other than cheating you realise? People might want to make mods for a game or just see how it works. Just take minecraft for example a game that is probably like 99% decompile, while there is a few cheats hanging around there is pleanty more content that is just harmless mods which add to the game.
