The idea was to hook the window, not change the name xD
And even then, I'd assume to change the name you first need to hook it which was the problem in the first place...
But I think I said it before, I used some regex in the window title search and now works for any client with "Phantasy Star Online Blue Burst" anywhere on it.
Also, I don't know if changing the window name will trigger Soda's anticheat measures, prolly not but well.. no need to mess around with that.
