Can you tell me what you're trying to achieve?

 

Hello @kiynox 

Thanks for your reply.

So basically I have this ARM64 Code :

mov w0,w21

I want to change W21 value if it's equals to (0xB0FF) then change it to (0xB0CC) that's it.

I am new to Game Guardian and it's powerful tool and I enjoy using it. I will be very thankful If you can help me

[How to make JMP/BR Opcode Injections in ARM64]

Hello scientists,

I am trying to make Opcode Injections for a game runs in ARM64 Device. 

In order to do that I have to use BR (Branch to Register). But I am currently getting error in GG and says : failed to organize arm64 opcode (movz x0, #0xE000).

I already allocated memory page it starts from address 78D26AE000 and here is the ARM64 Assembly Code I want to use :

movz x0, #0xE000
movk x0, #0x6AE0, LSL #16
movk x0, #0x78D2, LSL #32
br x0

The reason Im doing this because I want to inject this ARM64 Assembly Opcode in the game :

mov w0,w21

So I can check if W21 is equals to (0xB0FF) then change it to (0xB0CC) using this ARM64 Assembly Opcode :

cmp w21, #0xb0ff       
b.ne continue 
mov w21, #0xb0cc
continue:
// the remaining code.

Any helps or is there a better way to do it?

Kind regards.

[How to view .so (Shared Object) Functions Name and Address with Offset?]

Hello scientists,

I am trying to make Opcode Injections but I need to find the address with offset of the function which is inside "libmatch.so".

I also dumped IL2CPP functions in "libil2cpp.so" but the function I need is not in that dump file.

Any help please?
