I have the iDroid http://www.snakebyte-europe.com/en/container-produkte/products/android/idroidcon/
I have it set up in Game Controller mode.
It said it would auto detect it? It doesn’t work. I tried setting it to Keyboard mode and that works fine, I set my own keys and I can play the game, only bad thing is when I press a button, the reaction in the game is a bit delayed - any fix for that? Using on a Nexus 7.
