I have recently tried and succeeded to make Portal and Half Life 2 work on my OnePlus One (I can't tell how because it's illegal and against the rules of the forum I think, do your own research). The only problem is, I need the Nvidia Shield controller, or a ps3 / xbox / or any other android-supported controller, as there are no touch controls. My problem is that I don't have any controller of this type (except a Wiimote which doesn't work with Android kitkat). Here is my question : is there an app / overlay which can simulate a physical controller so I can play it without a physical controller ? I know it's quite hard, but I'm pretty desperate, as I can look at the beautiful menu screen, but am not able to control it. Does anyone have an idea ?
Thanks in advance.
