Help/Support Offset from LLDB

Ted2 · August 4, 2017

Hi,

I was trying to see if I could hack a game with ammo in it, since I've never played games like this lol

So I used lldb to set watchpoints from iGG adress, got a ida offset & removed aslr from it.

Then I loaded it in IDA, got the same instructions as lldb gave me, but for me it doesn't seem usefull at all.

1. It is a loc_.....

2. The sub_x function is long as hell & only used once

The loc_ function is this:

loc_1526D0                              ; CODE XREF: sub_150320+26F8�j
