Hey sorry for the late response, been away a few days:
I extended the hook you shared with me Relic to inject the memory as per Felipe's Auto Updater there:
Even so, the problem seems to be that I could not get the client to resize to the correct resolution that I set in the DLL. Instead, only the game scene would scale.
I can post some additional screenshots during my lunch break later today.
What I was wondering though is if Felipe's method of writing to memory here could change the window size of a window that is already created Or whether I would have to detour whatever the window draw function is to actually get it to resize.
