You run the program on your phone, and leave it running in the background. It will definitely work in Morphgear. It's been around for at least 2 years, so it's definitely not news.

I have an unbranded version of that joystick - and overall can't recommend it. It's poorly built, the buttons pop out or stick and there's a minute bluetooth lag. If you get it, update to the latest drivers from their website.

It also requires a program running in the background. It'll work with the keypress fix. But, that means that including the emulator, you'll have 3 programs running in memory. If the emulator is intensive - then the lack of memory will kick you out of one program suddenly. So you may no longer have joystick control and die abruptly.

Finally, the joystick can only hold the 6700 in portrait mode. So there's a lot of wasted screen.
