I haven’t. Not sure how well it would work. With one navi, there is a small issue where you have to restart it once or twice before it works. But then it is fine. With two navis that might get annoying.
I told Greg about it, hopefully he will fix that. He is going to add the trigger too. Right now I use the bumper as the trigger.
But I like the R1 anyway. It is kind of good to use it as the left controller as a free hand in game, for picking things up etc, and navi as a weapon.
