Solved: for those of you having this issue, there are actually two 8 byte (unsigned long long) GUIDs that need to be written.
So i've been working on a basic multibox program. One issue i'm currently having is all my macros are using /assist on the leader to get their target. When I switch targets fast however, it sometimes takes them up to 1 sec to switch targets because of the lag on assist as well as the latency between updating the follower client from when the leader client has switched targets.
I know I can read memory to get the GUID of my current target, but does anyone know what all you have to write in order to overwrite your target?
Thanks
