Help to make mod menu via dumping il2cpp

[ThienTeakee]

Hi guys,

I'm trying to make a mod menu for a game called "Space Shooter". I decompiled apk file, took libil2cpp.so and used il2cpp Dumper & dnSpy to dump it. So I had the function I want to modify and its information in the image bellow. What I have to do to find that function and change "0f" value insided it?

*** I used to hack it by editing the hex code of the il2cpp file but I couldn't turn it on/off or just turned on some needed features. That's why i want to do the above

Hope u guys can help

Sorry for my Eng

I think there are 2 ways of going about this

1) making the mod menu with GG using the offset to search and edit

2)using PMT's mod menu tutorial and injecting your own overlay menu made by following their tutorial.

Here's a decent tutorial on the PMT site that should be decently understandable for you https://platinmods.com/threads/mod-menu-for-il2cpp-and-native-android-games.64201/

Good luck!

Option 2 needs too much knowledge about Java. How can I search offsets in GG? I mean it has many type of value (DWORD, FLOAT,...) and I don't know what to choose :((

go to memory pages and hit the bulky arrow

Don't put in an address instead just hit XA and select the libil2cpp.so file (there isn't one for this game so I don't circle anything but your menu will look something like this choose the one with the libs file path)

This should give you the start of the lib files address, long press this and hit "offset calculator" then type in the offset from Dnspy and put a lowercase h and hit "go to"

This should bring you to the correct address

Shout out to @NoFear (sorry for pinging you) for his reply to my thread when I was wondering about searching offsets months back

Pretty sure from there you can search the address once you know it in hex which should help you go about automating the process with a script

I can't find libil2cpp.so in my menu. What do I need to do then?

Oh, I forgot. This game has 2 apk files: base and split_config_v8a. libil2cpp.so is in split_config_v8a file. I took them from /data/app with Root Explorer because it's a paid app.

Being a split apk shouldn't matter, but what app is it I'll take a look

The problem for GG WAS that it was a split apk, I was trying to post a non-split apk of the game but my internet is too bad and I was going to wait until I got to work tomorrow to do it. 

But glad to hear you got it working!

Yes, it worked with your help.

Oh, one more thing. Do u know how to dump il2cpp using GG? I searched but all tutorial videos were deleted. I used GG then choosed "Dump Memory" option but it had many "libil2cpp.so" lines which made me confused :((
