Sorry to butt in on this thread as well. The psmove_extend_z switch I mentioned in the other thread, it’s related to the start+select sync that has been done for over a year now with psmove. They discovered that the psmove start select gesture can be overridden and a hard coded value can be used. it’s something to look into, as it could be the new method for this, and it may cause others headaches, like I had, in the future.
