i have the gpdxd, and i wish to play with a friend. i connected an otg cable and an xbox 360 controller adapter, and booted up happy chick or whatever it's called. when i set up the controllers and whatnot, there's an issue with his controller. the buttons work fine, but when left, right, up or down is pressed, nothing happens. this dosent happen with every game i have, but i just want to play some gundam battle assault 2 with my friend.
