Help/Support Modifying ARM 64 instruction (IDA)

[G0DSTIER 17 iPhone 6s Plus 12.4]

I found currency related offset and I want to modify that but I don't know how to do it.

I already search TUT section but I only found the one for arm7 and not arm64.

 

LDR             W0, [X0,#0x48]

Let say I want to load x amount of money into W0 (88888 for example), How can i achieve that?

That is one of the thing that idk until now, My brain only able to digest SUB, ADD and BOOL. HAHAHA

You can use

MOV W0, #Number-Here
MOV W0, #9999

 

If you want specific numbers like 88888, you need to do some manual calculation, but you can still store large values normally using MOV like powers of 2. Eg. 16777216

You can try

MOV W0, #44444
MOV W1, #2
MUL W0, W0, W1
