PERFECT! Works like a champ. [r7.7] Once you have the necessary files  set up the relevant directories and configure the bluetooth or usb controller using OTG you'll be good to go. Confirmed working on galaxy note 3 SM-N900 (5.0 Stock)  Xperia Z Ultra (5.1.1 Custom - RXSW Z5 Experience)  HP Touchpad (4.4 Custom)  Galaxy S2 [r6] (Custom - Resurrection Remix). Once again great work guys. I appreciate your commitment. Madd respect.
