On the video below, it seems like it's possible to use two controllers with FPse: http://www.youtube.com/watch?v=VxflRaMdVKM
I get both controllers to detect on the Sixaxis Controller app. I can then use "Assign He keys" for both Pad 1 and 2 to the different controllers.
However, when I boot up Tekken 3 on my S3 (which boots fine and plays fine in single player), I have issues where both controllers are being detected for Player 1 (and the Player 2 selection icon keeps vibrating up/down/left/right on screen).
When I manage to setup a VS game, it seems that the directional movements in both controllers apply to Player 1, but the punch/kick/etc. buttons work for both player characters simultaneously (regardless of which controller is used).
On a Galaxy S3, any thoughts?
